Abstract
Steroid hormones are highly potent compounds that can disrupt the endocrine systems of aquatic organisms. This study explored the spatiotemporal distribution of 49 steroid hormones in agricultural soils, ditch water, and sediment from suburban areas of Guangzhou City, China. The average concentrations of Σsteroid hormones in the water, soils, and sediment were 97.7 ng/L, 4460 ng/kg, and 9140 ng/kg, respectively. Elevated hormone concentrations were notable in water during the flood season compared to the dry season, whereas an inverse trend was observed in soils and sediment. These observations were attributed to illegal wastewater discharge during the flood season, and sediment partitioning of hormones and manure fertilization during the dry season. Correlation analysis further showed that population, precipitation, and number of slaughtered animals significantly influenced the spatial distribution of steroid hormones across various districts. Moreover, there was substantial mass transfer among the three media, with steroid hormones predominantly distributed in the sediment (60.8 %) and soils (34.4 %). Risk quotients, calculated as the measured concentration and predicted no-effect concentration, exceeded 1 at certain sites for some hormones, indicating high risks. This study reveals that the risk assessment of steroid hormones requires consideration of their spatiotemporal variability and inter-media mass transfer dynamics in agroecosystems.

Abstract
The synthetic progestin, 17α-hydroxyprogesterone caproate (17-OHPC), is administered to pregnant individuals at risk for preterm birth and is likely transferred from mother to fetus. Yet, there is little information regarding the potential effects of 17-OHPC administration on behavioral and neural development in offspring. In rats, neonatal 17-OHPC exposure altered dopaminergic fiber distribution and density in the prelimbic medial prefrontal cortex (mPFC) in neonates and adolescents, respectively. Additionally, neonatal 17-OHPC exposure in male rats increased response omissions in a delay discounting task of impulsive decision-making. Because developmental 17-OHPC exposure has differential effects in males and females, investigating the effects of 17-OHPC on impulsive decision-making in female rats is necessary. The present study tested the effects of developmental 17-OHPC exposure (P1-P14) in a delay discounting task in which female rats chose between a small immediate reward and a larger delayed (0, 15 30, or 45 s) reward. 17-OHPC-exposed females made more omissions than controls. There was no effect of 17-OHPC on large reward preference nor on response time, and omissions were similar during both free- and forced-choice trials. The present study also aimed to investigate the neural mechanisms underlying omissions in 17-OHPC-exposed female rats. The dopamine transporter inhibitor, methylphenidate (MPH), was administered prior to delay discounting testing. MPH treatment did not reduce omissions in 17-OHPC-exposed females. If anything, MPH increased omissions in control females nearly fourfold during the longest delays. These results suggest that developmental 17-OHPC exposure increased omissions without affecting impulsivity or slowing decision-making. Furthermore, omissions may be regulated, at least in part, by dopaminergic mechanisms.

Abstract
A variety of progestogens are widely used by women for contraception and menopausal hormone therapy. The progestogens undergo extensive metabolism by oral and parenteral routes of administration to form many metabolites. Although a small number of metabolites have been shown to be biologically active, most have not been tested for biologic activity. The present review shows that we know most about progesterone metabolism, followed by the metabolism of levonorgestrel and norethindrone. Very few studies have been carried out on metabolism of most of the progestogens. The clinical significance of this deficiency is that those progestogen metabolites that bind to the progesterone receptors may also bind to other steroid receptors and be responsible for some of the well-documented side effects of administered progestogens. We also discuss how obesity and genetic polymorphisms alter progestogen metabolism, and how development of oral progestogen formulations that are targeted to the colon, where the concentration of steroid-metabolizing enzymes is much lower than in the proximal gut, may have a beneficial effect on progestogen metabolism.

Abstract
STUDY OBJECTIVE To explore the role of progestins as potential contributing factors for the development of hepatocellular adenoma (HA) METHODS: We describe 3 cases of adolescents and young adults who developed HA while on norethindrone (NET), as well as their management. In addition, we provide a comprehensive literature review on the association between progestins and HA. RESULTS Since 1983, 16 cases of HA in patients on progestins have been reported. Ten patients were on NET and 5 on a prodrug of NET (4 on norethindrone acetate [NETA] and 1 on lynestrenol). One individual had a norgestrel implant. Eight subsequently ceased all hormones: 4 experienced a size reduction, and 3 had complete resolution of their HA. Among our patients, 1 ceased NET and instead had a levonorgestrel intrauterine device inserted, and another swapped from NET to oral medroxyprogesterone acetate. Both experienced complete resolution of their HA. The third ceased NET and underwent a hysterectomy, with size reduction of her HA. CONCLUSION These cases and the literature review suggest an association between progestin exposure, in particular NET and its prodrugs, and the development of HA. The pathophysiology is unknown but may include peripheral conversion of NET and NETA to ethinyl estradiol or a specific action of 19-nortestosterone derivatives on hepatocytes, especially those with higher systemic doses compared with the levonorgestrel intrauterine device. There are no case reports relating to other forms of progestins, such as 17-hydroxyprogesterone, which may be important when considering alternative therapeutic options in females requiring effective menstrual management who have comorbidities.

Abstract
Progestins used in hormonal contraceptives and menopausal hormone therapy (MHT) have been linked to increased breast cancer risk. Whether the association holds for all progestins is unclear and the underlying mechanisms remain poorly understood. We directly compared the effects of four progestins (medroxyprogesterone acetate (MPA), norethisterone acetate (NET-A), levonorgestrel (LNG) and drospirenone (DRSP)) to each other and the natural progestogen progesterone (P4) on selected cancer hallmarks. To provide mechanistic insight into these effects, we assessed the role of the progesterone receptor (PR), and the extracellular signal-related kinase (ERK1/2) and c-Jun N terminal (JNK) signaling pathways. We showed that the increased proliferation of the luminal T47D breast cancer cell line by P4 and all progestins, albeit to different extents, was inhibited by PR knockdown and inhibition of both the ERK1/2 and JNK pathways. While knockdown of the PR also blocked the upregulation of MKI67 and CCND1 mRNA expression by selected progestogens, only a role for the ERK1/2 pathway could be established in these effects. Similarly, only a role for the ERK1/2 pathway could be confirmed for progestogen-induced colony formation, whereas both the ERK1/2 and JNK pathways were required for cell migration in response to the three older progestins implicated in the etiology of breast cancer, MPA, NET-A and LNG. Together our results show that all the progestins elicit their effects on cell proliferation via a mechanism requiring the PR, ERK1/2 and JNK pathways. While the ERK1/2 and JNK pathways are also required for increased cell migration by the older progestins, only a role for the ERK1/2 pathway could be established in their effects on colony formation. Notably, the cytoplasmic PR was not needed for activation of the ERK1/2 pathway by the progestogens. Given that DRSP showed significantly lower proliferation than MPA and NET-A, and that it had no effect on breast cancer cell migration and colony formation, hormonal formulations containing the newer generation progestin DRSP may provide a better benefit/risk profile towards breast cancer than those containing the older generation progestins.

Abstract
Progestin-primed ovarian stimulation (PPOS) is being increasingly used for ovarian stimulation in assisted reproductive technology. Different progestins have been used with similar success. The available studies suggest a similar response to ovarian stimulation with gonadotrophin-releasing hormone (GnRH) analogues. Any differences in the duration of stimulation or gonadotrophin consumption are minor and clinically insignificant. PPOS has the advantage of oral administration and lower medication costs than GnRH analogues. As such it is clearly more cost-effective for fertility preservation and planned freeze-all cycles, but when fresh embryo transfer is intended PPOS can be less cost-effective depending on the local direct and indirect costs of the additional initial frozen embryo transfer cycle. Oocytes collected in PPOS cycles have similar developmental potential, including blastocyst euploidy rates. Frozen embryo transfer outcomes of PPOS and GnRH analogue cycles seem to be similar in terms of both ongoing pregnancy/live birth rates and obstetric and perinatal outcomes. While some studies have reported lower cumulative live birth rates with PPOS, they have methodological issues, including arbitrary definitions of the cumulative live birth rate. PPOS has been used in all patient types (except progesterone receptor-positive breast cancer patients) with consistent results and seems a patient friendly and cost-effective choice if a fresh embryo transfer is not intended.

Abstract
Endometriosis is characterized by the implantation of endometrial cells outside the uterus. This hormone-dependent disease is highly prevalent among women of reproductive age. Clinical symptoms of endometriosis include dysmenorrhea, pelvic pain, and infertility, which can negatively impact the overall quality of life of those affected. The medical treatment of endometriosis serves as an important therapeutic option, aimed at alleviating pain associated with the condition and suppressing the growth of endometriotic lesions. As such, it is employed as an adjuvant therapy following surgery or an empirical treatment after the clinical diagnosis of endometriosis. Dienogest, a fourth-generation progestin, has received approval for the treatment of endometriosis in many countries. A growing body of evidence has demonstrated its efficacy in managing endometriosis-associated pain, preventing symptoms, and reducing lesion recurrence. In this review, we examine the clinical efficacy, safety, and tolerability of dienogest in treating endometriosis. We also provide updated findings, drawing from clinical studies that focus on the long-term use of this medication in patients with endometriosis.

Abstract
Sexuality in people with mental disorders is a topic usually tinged with prejudice and stigma. Women with severe mental disorders are more exposed to suffer sexually transmitted diseases, becoming victims of gender violence and being involved with unintended pregnancies. In adults and adolescents, sexual intercourse under the influence of alcohol or other drugs, or during worsening or exacerbation of baseline symptoms or condition, are often unplanned, unprotected, with casual partners from high risk groups, without contraceptive methods and with less capacity to agree or deny safe sexual practices. Sexual and reproductive rights as well as gender perspective need to be considered an integral part of women with mental disorders health being and treatment. For this reason, discussing with patients about their desire or not to have children, their sexual life and provide them the most adequate options of contraceptive methods taking into consideration their needs so that and informed decision should be part of the psychiatric consultation. Hormonal contraceptives are widely used globally, being one of the most prescribed groups of drugs. It is estimated that more than 100 million women take oral contraceptives to prevent pregnancy, to treat menstrual pain and/or menstrual heavy bleeding or to control acne. Oral contraceptives result from the combination of estrogen and progestin derivatives, or progestins alone. This review will focus on the description of each hormonal contraceptive methods and hormone replacement therapy and the special features of their concomitant use with psychotropic drugs during treatment of women with psychiatric disorders.

Abstract
The risks of meningioma associated with the use of cyproterone acetate at high doses (25 to 100 mg/day) have been known since 2007. Recently, two additional molecules have been incriminated: nomegestrol acetate and chlormadinone acetate. The higher the cumulative dose and the longer the treatment duration, the bigger the risk of meningioma (12-fold after 5 years of treatment for nomegestrol acetate, and 7-fold after 3.5 years of treatment for chlormadinone acetate). Nevertheless, these medications have many indications that demonstrate their importance in the daily practice of the general practitioner, of the gynecologist and of the reproductive endocrinologist. Therefore, caution is required when introducing a powerful progestin that is incriminated in the long term at high doses. If the benefit/risk balance favours the initiation of progestin therapy, it is recommended to use the minimal effective dose and to limit the duration of use. Clinical and brain imaging monitoring should also be performed. Finally, if a meningioma develops on progestin, it is recommended that any medication containing a progesterone agonist be suspended.

Abstract
We developed and validated the use of ultra-high-performance liquid chromatography-heated electrospray ionization-tandem triple quadrupole mass spectrometry to simultaneously analyze serum concentrations of ethinylestradiol, dienogest, norelgestromin, norethindrone, gestodene, levonorgestrel, etonogestrel, segesterone acetate, medroxyprogesterone acetate, and drospirenone. The calibration range for all targets was 0.009-10 ng/mL, with lower limit of quantification of 0.009 ng/mL for all analytes except gestodene (0.019 ng/mL). We used our assay to check compliance among participants in a clinical trial, confirmed the use of drospirenone in 11 of 13 study participants, and evidence of noncompliant progestins in 2 (levonorgestrel = 1, norethindrone = 1). We conclude that this approach provides an accurate method to check protocol compliance in contraceptive clinical trials. IMPLICATIONS: The availability of a liquid chromatography-tandem triple quadrupole mass spectrometry multiprogestin analysis panel for simultaneous evaluation of the most common contraceptive steroids approved worldwide could improve monitoring of compliance and protocol adherence in clinical trials.

Abstract
Progestins (synthetic progestogens) are progesterone receptor (PR) ligands used globally by women in both hormonal contraception and menopausal hormone therapy. Although four generations of unique progestins have been developed, studies seldom distinguish between the activities of progestins via the two functionally distinct PR isoforms, PR-A and PR-B. Moreover, not much is known about the action of progestins in breast cancer tumors where PR-A is mostly overexpressed relative to PR-B. Understanding progestin action in breast cancer is crucial since the clinical use of some progestins has been associated with an increased risk of developing breast cancer. This study directly compared the agonist activities of selected progestins from all four generations for transactivation and transrepression via either PR-A or PR-B, and when PR-A and PR-B were co-expressed at ratios comparable to those detected in breast cancer tumors. Comparative dose-response analysis showed that earlier generation progestins mostly displayed similar efficacies for transactivation on a minimal progesterone response element via the PR isoforms, while most of the 4th generation progestins, similar to the natural progestogen, progesterone (P4), were more efficacious via PR-B. Most of the progestogens were however more potent via PR-A. We are the first to show that the efficacies of the selected progestogens via the individual PR isoforms were generally decreased when PR-A and PR-B were co-expressed, irrespective of the ratio of PR-A:PR-B. While the potencies of most progestogens via PR-B were enhanced when the ratio of PR-A relative to PR-B was increased, those via PR-A were minimally influenced. This study is also the first to report that all progestogens evaluated, except 1st generation medroxyprogesterone acetate and 4th generation drospirenone, displayed similar agonist activity for transrepression via PR-A and PR-B on a minimal nuclear factor kappa B containing promoter. Moreover, we showed that the progestogen activity for transrepression was significantly increased when PR-A and PR-B were co-expressed. Taken together, our results highlight that PR agonists (progestogens) do not always display the same activity via PR-A and PR-B, or when PR-A and PR-B are co-expressed at ratios mimicking those found in breast cancer tumors. These results suggest that biological responses are progestogen- and PR isoform-dependent and may differ in target tissues expressing varying PR-A:PR-B ratios.

Abstract
OBJECTIVES To evaluate oncologic and pregnancy outcomes of fertility-sparing treatment (FST) using progestin in patients with stage I grade 2 endometrioid endometrial cancer (EC) without myometrial invasion (MI) or grade 1-2 with superficial MI. METHODS Multicenter data of patients with stage I grade 2 EC without MI or grade 1-2 EC with superficial MI, who received FST between 2005 and 2021, were analyzed. Cox regression analysis identified independent factors for progressive disease (PD) during the FST. RESULTS Altogether, 54 patients received FST [medroxyprogesterone acetate (500-1000 mg) in 44, megestrol acetate (40-800 mg) in 10] with concurrent levonorgestrel-releasing intrauterine devices use in 31. With median time to achieve a complete response (CR) of 10 (3-24) months, 39 patients (72.2%) achieved CR. Of the 15 patients who attempted to conceive after achieving CR, 7 (46.7%) became pregnant (2 abortions, 5 live births). During a median FST duration of 6 (3-12) months, nine patients (16.6%) were diagnosed with PD. Fifteen (38.5%) experienced recurrence with a median recurrence-free survival of 23 (3-101) months. In the multivariable analysis, tumor size before FST ≥2 cm (HR 5.456, 95% CI 1.34 to 22.14; p = 0.018) was significantly associated with a high PD rate during FST. CONCLUSION The overall response rate to FST was promising, however, the PD rate was significant during the first 12 months of FST. Therefore, performing thorough endometrial biopsy and imaging studies is essential to strictly evaluate the extent of the disease every 3 months from FST initiation.

Abstract
To examine the effectiveness of progestin re-treatment for recurrent endometrial intraepithelial neoplasia (EIN), atypical endometrial hyperplasia (AH) and endometrial cancer (EC) following initial fertility-sparing treatment. A comprehensive systematic review and meta-analysis were conducted by an Expert Panel of the Japan Society of Gynecologic Oncology Endometrial Cancer Committee. Multiple search engines, including PubMed/MEDLINE and the Cochrane Database, were searched in December 2021 using the keywords "Endometrial neoplasms," "Endometrial hyperplasia," "Endometrial intraepithelial neoplasia," "Fertility preservation," "Progestins," AND "Recurrence." Cases describing progestin re-treatment for recurrent EIN, AH and EC were compared with cases that underwent conventional hysterectomy. The primary outcomes were survival and disease recurrence, and the secondary outcome was pregnancy. After screening 238 studies, 32 with results for recurrent treatment were identified. These studies included 365 patients (270 received progestin re-treatment and 95 underwent hysterectomy). Most progestin re-treatment involved medroxyprogesterone acetate or megestrol acetate (94.5%). Complete remission (CR) following progestin re-treatment was achieved in 219 (81.1%) cases, with 3-, 6- and 9-month cumulative CR rates of 22.8%, 51.7% and 82.6%, respectively. Progestin re-treatment was associated with higher risk of disease recurrence than conventional hysterectomy was (odds ratio [OR]=6.78; 95% confidence interval [CI]=1.99-23.10), and one patient (0.4%) died of disease. Fifty-one (14.0%) women became pregnant after recurrence, and progestin re-treatment demonstrated a possibility of pregnancy (OR=2.48; 95% CI=0.94-6.58). This meta-analysis suggests that repeat progestin therapy is an effective option for women with recurrent EIN, AH and EC, who wish to retain their fertility.

Abstract
BACKGROUND Exogenous progestins are an effective tool for hormonal contraception and family planning. Progestins may be delivered as oral pills, intramuscular or subcutaneous injections, vaginal rings, or intrauterine devices. Drug concentrations may vary based on the route and duration of delivery. Measurement of synthetic steroids in blood plasma can aid in determination of product adherence, evaluation of drug-drug interactions, and investigation of unintended pregnancies. METHODS Drug-free K2EDTA plasma was spiked with the synthetic steroids etonogestrel (ETO), levonorgestrel (LNG), medroxyprogesterone acetate (MPA), and norethisterone (NET). Plasma was combined with isotopically labeled internal standards, and drugs were extracted via liquid-liquid extraction. Samples were then subjected to liquid chromatographic-tandem mass spectrometric (LC-MS/MS) analysis. The method was validated in accordance with regulatory recommendations. The assay was evaluated in a cohort of remnant plasma samples in individuals using one of the aforementioned progestins. RESULTS The analytical measuring range for ETO, MPA, and NET was 20-10,000 pg/mL; the primary linearity for LNG was 20-20,000 pg/mL. The method showed acceptable precision and accuracy for all progestins. Stability was established for 72 h with room temperature storage and through 3 freeze-thaw cycles. All analytes were stable in whole blood incubated at room temperature for 25 h, and at 40°C and 100% humidity for 2 h. Ion suppression was observed for all analytes spiked in plasma; average ion suppression was 31.6%, 66.6%, 32.1% and 41.2% for ETO, LNG, MPA, and NET, respectively. However, internal standards showed comparable ion suppression, and relative matrix effects were minimal. ETO, LNG, MPA, and NET could also be quantified accurately in K3EDTA plasma and serum. Progestins were successfully measured in remnant samples from individuals using hormonal contraceptives. CONCLUSIONS A multiplexed LC-MS/MS assay for the quantification of ETO, LNG, MPA, and NET has been developed and validated. The assay met acceptable performance characteristics and may be used in downstream studies to evaluate progestin pharmacology.

Abstract
OBJECTIVES Exogenous estrogen is associated with growth of hepatocellular adenomas (HCAs), although the influence of progestin-only agents is unknown. We therefore evaluated the association of progestin-only agents on HCA progression compared to no hormone exposure and compared to estrogen exposure in female patients. STUDY DESIGN In this single-center, retrospective cohort study of reproductive-aged female patients (ages 16-45) with diagnosed HCAs between 2003 and 2021, we evaluated radiographic HCA growth during discrete periods of well-defined exogenous hormone exposures. RESULTS A total of 34 patients were included. Nineteen (55.9%) had follow-up scans during periods without hormone exposure, 7 (20.6%) during estrogen exposure, and 8 (23.5%) during progestin-only exposure. Over a median follow-up of 11 months, percent change in sum of adenoma diameters from baseline to last available scan was -15.0% with progestin-only agents versus 29.4% with estrogen exposure (p = 0.04), and -7.4% with no hormonal exposure (p = 0.52 compared to progestin-only). Greater than 10% growth was observed in two individuals (25.0%) with progestin-only agent use (one patient on high-dose progestin for menorrhagia) versus five individuals (71.4%) with estrogen use (p = 0.13), and 7 (36.8%) with no exogenous hormone use (p = 0.68 vs progestin-only). CONCLUSIONS During discrete periods of progestin-only use, HCA growth overall declined, similar to declining growth during periods without exogenous hormonal exposure. This differed from discrete periods of exogenous estrogen exposure, during which time HCAs demonstrated overall increased growth. Though larger studies are needed, these findings support recent guidance supporting progestin-only agents for female patients with HCAs seeking non-estrogen alternatives for contraception. IMPLICATIONS In this small retrospective study, we observed overall decrease in HCA size during discrete periods of progestin-only contraception use, similar to that observed during periods without exogenous hormone exposure, supporting their use as a safe alternative to estrogen-containing contraceptives in this patient population.

Abstract
Although copulatory behavior is thought to have a strong innate basis in mice, there is also clear evidence that sexual experience shapes its expression. Reinforcement of behavior through rewarding genital tactile stimulation is a primary candidate mechanism for this modification. In rats, manual tactile clitoral stimulation is rewarding only when it is temporally distributed, which is hypothesized to result from an innate preference for species-typical copulatory patterning. Here we test this hypothesis using mice, which have a temporal copulatory pattern which is distinctly less temporally distributed than that of rats. Female mice received manual clitoral stimulation which was either temporally continuous every second, or stimulation which was temporally distributed, occurring every 5 s, This pattern of stimulation was paired with environmental cues in a conditioned place preference apparatus to assess reward. Neural activation in response to this stimulation was evaluated by measuring FOS immunoreactivity. Results indicated that both temporal patterns of clitoral stimulation were rewarding, but that continuous stimulation better reproduced brain activation associated with sexual reward. Furthermore, continuous, but not distributed stimulation elicited a lordosis response in some females, and this response increased within and across days. Sexual reward, neural activation and lordosis resulting from tactile genital stimulation were eliminated by ovariectomy and restored with combined 17β-estradiol and progesterone treatment but not 17β-estradiol treatment alone. These observations are consistent with the hypothesis that sexual reward resulting from species-typical genital tactile stimulation has a permissive effect on copulatory behavior of female mice.

Abstract
Studies directly comparing the efficacies and potencies of multiple progestins used in contraception and menopausal hormone therapy (MHT) in parallel via human progesterone receptor isoform A (PR-A) in the same model system are limited, and how these parameters are influenced by the density of PR-A are unclear. This is surprising as it is known that the expression levels of PR-A vary in different tissues and diseases. We thus determined for the first time the relative efficacies and potencies for transactivation of the natural PR ligand, progesterone (P4), the PR-specific agonist promegestone (R5020), and selected progestins from all four generations in parallel via different densities of PR-A overexpressed in the MDA-MB-231 breast cancer cell line. Comparative dose-response analysis showed that P4, R5020, the 1st generation progestins medroxyprogesterone acetate and norethisterone, 2nd generation progestin levonorgestrel, 3rd generation progestin gestodene, as well as 4th generation progestins nesterone, nomegestrol acetate and drospirenone display differential agonist efficacies and potencies via PR-A. Moreover, we showed that the agonist efficacies and potencies of the progestins via PR-A were modulated in a density- and progestin-specific manner. Our finding that the potencies of the progestins via PR-A, at all densities, do not exceed reported progestin serum concentrations in women, suggest that these progestins are likely to elicit similar effects in vivo. We are the first to report that P4 and the selected progestins display similar agonist activity for transrepression via PR-A, and that the density of PR-A enhances the transrepression activity of some, but not all progestogens. Collectively, our findings provide proof of concept that the effects of the selected progestins via PR-A is progestin-specific and dependent on the density of the receptor, suggesting differential progestin responses in women using these progestins in contraception and MHT.

Abstract
BACKGROUND Endometriosis is a complex chronic disease that affects approximately 10% of women of reproductive age worldwide and commonly presents with pelvic pain and infertility. METHOD & OUTCOME MEASURES A systematic review of the literature was carried out using the databases Pubmed, Scopus, Cochrane and ClinicalTrials.gov in women with a confirmed laparoscopic diagnosis of endometriosis receiving progestins to determine a reduction in pain symptoms and the occurrence of adverse effects. RESULTS Eighteen studies were included in the meta-analysis. Progestins improved painful symptoms compared to placebo (SMD = -0.61, 95% CI (-0.77, -0.45), P < 0.00001) with no comparable differences between the type of progestin. After median study durations of 6-12 months, the median discontinuation rate due to adverse effects was 0.3% (range: 0 - 37.1%) with mild adverse effects reported. CONCLUSION The meta-analysis revealed that pain improvement significantly increased with the use of progestins with low adverse effects. SYSTEMATIC REVIEW REGISTRATION PROSPERO CRD42021285026.

Abstract
Hormonal contraceptives (HCs) and hormone replacement therapy (HRT) are therapies designed to target the progesterone receptor (PR) to prevent unwanted pregnancy and to alleviate the symptoms of menopause, respectively, in women. Although these therapies are widely used globally, few studies have investigated in parallel how the transcriptional responses of the progestogens used in these therapies compare to each other via the PR isoforms (PR-A and PR-B). Using dose-response promoter-reporter and endogenous gene expression assays, we compared the transcriptional responses of six widely-used progestogens via each PR isoform. The present study shows that progestogens exhibit progestogen-specific potencies and efficacies via both PR isoforms. In addition, the endogenous gene expression data reveals that progestogens exhibit promoter-specific effects. Furthermore, this study reveals that progestogen responses via PR-A are significantly more potent and less efficacious than those observed via PR-B, and that this is unlikely due to differences in PR protein levels. Correlation analysis revealed that there is no detectable correlation between potency or efficacy of progestogens for PR-B or PR-A versus reported relative binding affinity (RBA) of progestogens for the PR, consistent with complex mechanisms of PR regulation. Taken together, our data show that it cannot be assumed that all progestogens have similar transcriptional responses on all genes. Since the PR plays a role in cognition, regulation of inflammation, mitochondrial function, neurogenesis, female reproduction and disease, the data suggest that these important physiological functions could be differentially affected depending on progestogen, promoter, and ratios of PR isoforms.

Abstract
The consumption of progestins has increased considerably in recent decades, as has their disposal into the environment. These substances can negatively affect the reproduction, physiology, and behavior of non-target organisms, such as fish. We aimed to evaluate the effects of exposure to environmentally relevant concentrations of levonorgestrel-control birth based (1.3, 13.3, 133, and 1330 ng/L) on the development and behavior of zebrafish (Danio rerio) in terms of mortality, hatching, spontaneous movement, and larval and adult behavioral tests. Exposure caused anxiogenic-like behavior in larvae, which persisted in adults, as demonstrated by the light-dark test. In contrast, it caused anxiolytic-like behavior in the novel tank test. There was a high mortality rate at all tested concentrations and increases in the hormone cortisol at 13.3 ng/L that affected the sex ratio. These changes may lead to an ecological imbalance, emphasizing the risk of early exposure to progestins in the environment.

Abstract
Background This study aimed to investigate the medroxyprogesterone acetate (MPA) + HMG protocol vs ultra-long gonadotrophin releasing hormone (GnRH) agonist protocol in patients with advanced ovarian endometriosis who received in vitro fertilization (IVF). Methods Three hundred patients with advanced ovary endometriosis who underwent IVF were included, and embryological and clinical outcomes were assessed between March 2017 and September 2017. Patients were divided into MPA + HMG group and 1-month ultra-long GnRHa protocol group. Results Lower hMG dose and shorter medication time were found in the MPA + HMG group than in the GnRHa group (P < 0.05). Follicle to-Oocyte Index was significantly different between MPA + HMG group and GnRHa group (P < 0.001). No differences were found in the ovary response and numbers of mature oocytes, fertilized oocytes and viable embryos. The clinical pregnancy and live birth outcomes were similar between MPA + HMG group and GnRHa group, and these outcomes were independent of fresh or frozen embryo transfer in the GnRHa protocol group. There were no significant differences in the time to embryo transfer, medical cost and adverse effects. Conclusion The number of oocytes retrieved and pregnancy outcomes after MPA + HMG protocol are similar to those after ultra-long GnRHa protocol in women with ovarian endometriosis. MPA + HMG protocol may be an alternative to ultra-long GnRHa protocol for IVF in ovary endometriosis patients. Trial registration The trial was registered in the Chinese Clinical Trial Registry (ChiCTR-INR-17010924) Plain English summary In conclusion, the administration of MPA in COH showed similar number of oocytes retrieved, no premature LH surge, and similar pregnancy and live birth outcomes in patients with advanced ovarian endometriosis undergoing IVF/ICSI as compared to the one-month long protocol. The use of MPA in COH appears to be promising although many questions remain to be elucidated, including the dose and time of progestin priming as well as its possible influence on the oocyte development potential and microenvironment. Given their good tolerability, few metabolic influence, and low cost, progestogens provide a novel alternative to the conventional protocol for patients with endometriosis.

Abstract
BACKGROUND There has been increasing interest in medical management of uterine Arteriovenous Malformations (AVMs) in hemodynamically stable patients as a means of decreasing the need for invasive treatment that may impact fertility. CASES Amongst six cases of sonographically diagnosed uterine AVM managed medically with combined oral contraceptive pills or medroxyprogesterone acetate, three experienced complete resolution and three experienced partial resolution. Amongst those with complete resolution, all had a subsequent pregnancy that had no complication attributable to previous AVM or medical therapy. Amongst those with partial resolution, one is currently pregnant, one remains on therapy, and one has discontinued treatment with resumption of normal menses. CONCLUSION Medical management is effective in completely or partially resolving uterine AVMs. Subsequent pregnancies in this population are feasible and are not at higher risk for perinatal complications.

Abstract
The glucocorticoid receptor (GR) regulates transcription of genes involved in multiple processes. Medroxyprogesterone acetate (MPA), widely used in the injectable contraceptive Depo-MPA (DMPA), has off-target effects via the GR, which may result in side-effects in endocrine therapy. However, very little is known about the GR activity of other progestins used in endocrine therapy. This study compared GR activities for several progestins, using whole cell binding, dose-response, and GR phosphorylation assays, in both a cell line model and peripheral blood mononuclear cells (PBMCs). MPA, etonogestrel (ETG) and nestorone (NES) exhibit greater relative binding affinities for the GR than levonorgestrel (LNG) and norethisterone/norethindrone (NET) and are partial GR agonists for transactivation but agonists for transrepression on synthetic promoters in COS-1 cells. MPA is a potent agonist for endogenous GR-regulated GILZ and IL6 genes in PBMCs. While ETG and NES also display agonist activity on IL6, they have little effect on GILZ. In contrast, LNG and NET exhibit little to no activity in transactivation models, while both exhibit some transrepressive activity but are generally less potent and/or efficacious than MPA. Antagonist and phosphorylation assays confirmed that MPA and NES act via the GR on endogenous genes in PBMCs. Our results suggest GR-mediated dose-dependent and gene-specific transcriptional side-effects are likely to occur at physiologically relevant concentrations in vivo for MPA, may possibly occur selectively for ETG and NES, but are unlikely to occur for LNG and NET. This suggests that these progestins will exhibit differential side-effects in endocrine therapy via the GR.

Abstract
Emerging evidence suggests that the novel Coronavirus disease-2019 (COVID-19) is deadlier for men than women both in China and in Europe. Male sex is a risk factor for COVID-19 mortality. The meccanisms underlying the reduced morbidity and lethality in women are currently unclear, even though hypotheses have been posed (Brandi and Giustina in Trends Endocrinol Metab. 31:918-27, 2020). This article aims to describe the role of sex hormones in sex- and gender-related fatality of COVID-19. We discuss the possibility that potential sex-specific mechanisms modulating the course of the disease include both the androgen- and the estrogen-response cascade. Sex hormones regulate the respiratory function, the innate and adaptive immune responses, the immunoaging, the cardiovascular system, and the entrance of the virus in the cells. Recommendations for the future government policies and for the management of COVID-19 patients should include a dimorphic approach for males and females. As the estrogen receptor signaling appears critical for protection in women, more studies are needed to translate the basic knowledge into clinical actions. Understanding the etiological bases of sexual dimorphism in COVID-19 could help develop more effective strategies in individual patients in both sexes, including designing a good vaccine.

Abstract
Progestins and estrogens are widespread in various aquatic environments and their potential endocrine disruption effects to aquatic organisms have drawn growing concern. However, their combined effects in aquatic organisms remain elusive. The aim of the present study was to assess the effects of the binary mixtures of gestodene (GES) and 17α-ethinylestradiol (EE2) on the hypothalamic-pituitary-thyroid (HPT) axis of zebrafish (Danio rerio) using the eleuthero-embryos. Embryos were exposed to GES and EE2 alone or in combination at concentrations ranging from 41 to 5329 ng L-1 (nominal ones from 50 to 5000 ng L-1) for 48 h, 96 h and 144 h post fertilization (hpf). The results showed that the transcripts of the genes along the HPT axis displayed pronounced alterations. There was no clear pattern in the change of the transcripts of these genes over time and with concentrations. However, in general, the transcripts of the genes were inversely affected by EE2 (increase 0.5 to 4.2-folds) and GES (inhibition 0.4 to 4.9-folds), and their mixtures showed interactive effects in embryonic zebrafish. In addition, physiological data (mortality, malformation, body length and heart rate etc.) denoted higher toxicity of the two chemicals in combination than alone based on the developmental toxicity and neurotoxicity (locomotor behavior). These results indicated that the interactive effects of these two chemicals might be different between at the transcriptional level and at the whole organismal level. In summary, GES and EE2 affect the HPT axis (related genes expression and thyroid hormones (THs) levels) and exhibit developmental toxicity and neurotoxicity.

Abstract
PURPOSE Medical management of adenomyosis largely revolves around symptom management, with very few drugs having received regulatory approval for the disease. However, the level of evidence supporting the use of pharmacological interventions is low, making it difficult to establish their efficacy in the treatment of adenomyosis. Hence, the aim of our systematic review is to identify the strength of evidence currently available and evaluate the effectiveness of different medical interventions in the management of adenomyosis. METHODS The search was performed in MEDLINE, Embase, Cochrane Library, CENTRAL and ClinicalTrials.gov. Articles published between 1 January 2010 and 30 November 2020 were considered. Randomized controlled trials and observational studies that assessed the efficacy of medical interventions in patients with adenomyosis were included. The quality of the data was analyzed using RevMan 5.3 software. RESULTS LNG-IUS (levonorgestrel intrauterine system), dienogest and gonadotropin-releasing hormone (GnRH) analogues were effective in reducing pain, uterine volume and menstrual bleeding. However, these data were largely obtained in the non-trial setting and were fraught with issues that included patient selection, short duration of therapy, small sample size, and limited long-term safety and effectiveness data. CONCLUSIONS Although LNG-IUS, dienogest and GnRH analogues have better evidence for effectiveness in adenomyosis, the need of the hour is to thoroughly evaluate other novel molecules for adenomyosis using well-designed randomized controlled trials.

Abstract
INTRODUCTION Although several studies suggest beneficial effects of low-dose estrogen-progestins (LEPs) and progestins on dysmenorrhea in Japanese women, the difference in efficacy between drugs remains unknown. METHODS We identified studies by searching the MEDLINE, Cochrane Library, and ICHUSHI databases and included randomized controlled trials (RCTs) that used total dysmenorrhea score and visual analogue scale (VAS) as outcome measures to evaluate LEPs and progestins for primary and secondary dysmenorrhea. We analyzed results by meta-analysis and network meta-analysis (NMA). RESULTS We identified 10 articles on eight RCTs and included seven drugs (six LEPs and one progestin, i.e., dienogest) and placebo in the analysis. Meta-analysis showed improvements in total dysmenorrhea score and VAS for almost all drugs compared with placebo. In NMA, VAS in secondary dysmenorrhea improved more with dienogest than with norethisterone/ethinylestradiol (mean difference - 25.84 [95% CrI - 44.46 to - 7.15]). In the comparison of administration regimens, VAS improved more with progestin-continuous than LEP-cyclic and the surface under the cumulative ranking (SUCRA) of LEP-extended and progestin-continuous appeared to be higher than that of LEP-cyclic. CONCLUSIONS We confirmed that LEPs and dienogest are effective for primary and secondary dysmenorrhea and suggest that continuous regimens may be more effective than cyclic regimens in improving outcomes.

Abstract
INTRODUCTION Hormonal contraceptives have been used in perimenopausal women to manage a variety of symptoms and prevent unintended pregnancy. However, it is unclear what contraceptive regimen is best for these women. OBJECTIVE To evaluate hormonal contraceptive methods in women experiencing perimenopause using two prespecified outcomes: perimenopausal symptom management and long-term effects. METHODS A literature search of PubMed and EMBASE databases was performed (January 1990 to October 2021) using search terms "perimenopause" and "contraception." Relevant full-text articles in English were included. RESULTS Fifteen clinical articles were reviewed. Fourteen were internationally-based and one study was conducted in the United States. Nine articles evaluated symptom resolution, and six of these nine reported statistically significant changes in favor of treating perimenopausal women with hormonal contraceptives compared with no treatment. Seven studies evaluated long-term outcomes including bone loss and metabolic parameters, and six of these seven showed statistically significant improvements with hormonal contraceptives. Based on limited data and a lack of comparative studies, the use of a levonorgestrel intrauterine device with supplemental low-dose menopausal estrogen has positive results for the management of disruptive perimenopausal symptoms and long-term outcomes. CONCLUSION Hormonal contraception in perimenopausal women improves symptom management and long-term outcomes if patients do not have contraindications. When selecting a contraceptive for women in perimenopause, clinicians and pharmacists need to address specific patient risk factors, symptom profiles, long-term risks and benefits, and patient preferences.

Abstract
OBJECTIVES To compare body mass index (BMI) changes in adolescents using long-acting reversible contraceptives (LARCs), specifically, the etonogestrel subdermal implant (ENG-implant), levonorgestrel intrauterine device (LNG-IUD), and copper IUD (Cu-IUD), by initial BMI category from the time of LARC insertion to within 6-18 months after insertion. DESIGN This was a single-center retrospective cohort study. SETTING AND PARTICIPANTS We reviewed electronic health records from our large health system to identify and follow a cohort of 196 adolescents aged 14-19 years with LARCs inserted from 2010 to 2016. We excluded adolescents with conditions or medications affecting weight, including childbirth. MAIN OUTCOME MEASURE BMI change from LARC insertion to first BMI documented after 6-18 months RESULTS: Mean age was 17.2 ± 0.2 years; 59% of the cohort was Hispanic and 29% Black. Mean BMI was 26.4 ± 7.1 kg/m2. Of the total cohort of adolescents, 51% were underweight/normal, 24% overweight, and 25% obese. Mean time to first BMI documented after LARC insertion was 10.1 ± 3.2 months. Mean BMI change for the total cohort was +0.73 ± 1.8 kg/m2, indicating weight gain. Mean BMI change for the ENG-implant + LNG-IUD users (n = 127) was larger than for Cu-IUD users (n = 69) (+0.92 ± 1.9 kg/m2 vs +0.37 ± 1.6 kg/m2, respectively, P < .05). Two-way analysis of variance showed that both initial BMI category (P = .001) and type of LARC (P = .011) had an independent significant main effect on BMI change. A significant interaction effect (P = .017) showed that obese adolescents had a larger increase in BMI when they were using a progestin-releasing LARC, either ENG-implant or LNG-IUD, as compared to a Cu-IUD (P < .05). CONCLUSION Adolescents using progestin-releasing LARCs had a larger increase in BMI within 6-18 months after device insertion than those using Cu-IUDs. The disproportionate increase in BMI with progestin-releasing LARCs was primarily contributed by obese users.

Abstract
INTRODUCTION The relationship between meningioma and progestins has not been elucidated. Meningioma regression after acetate cyproterone (CA) withdrawal has been reported. Our purpose was to evaluate the meningioma evolution after withdrawal of progestins in patients who underwent long-term exposure to CA, nomegestrol acetate (NA), chlormadinone acetate (ChlA). METHODS Our study retrospectively included 69 patients with intracranial meningioma and exposed to one of these 3 progestins between December 2006 and March 2019. In each patient, clinico-radiological (MRI) follow-up was performed every 6 months after diagnosis and treatment withdrawal recommendation. Statistical analyses were applied to compare tumor location and respect of prescription rules between the 3 groups. RESULTS The mean hormonal exposure was 16 years in CA group (n = 46), 16 years in NA group (n = 12) and 9.7 years in ChlA group (n = 11). A higher rate of "out of label" use was observed in the CA group (p = 0.003). Multiple meningiomas were demonstrated in more than 60% of cases in each group. Anterior skull base location was noted in 60.5% of cases in CA group, 25% of cases in NA group and 36.7% of cases in ChlA group (p = 0.05). Incomplete tumor regression was recorded in 11 cases of CA group and in 2 cases of ChlA group. CONCLUSION In CA group, our results suggest a strong relationship between this treatment and development of intracranial meningioma. In presence of voluminous asymptomatic meningioma, treatment can be delayed due to the potential regression after withdrawal. On the contrary in NA and ChlA groups, further studies are needed.

Abstract
Background Estrogen therapy in early menopausal women decreases the risk of coronary heart disease and parenteral, but not oral, estrogen is reported to reduce blood pressure (BP). Progestogens are typically added to estrogens to prevent unopposed endometrial stimulation. The effects of progestogen on BP have been less well studied to date. This study was conducted to explore the impacts of micronized progesterone (MP4) combined with percutaneous estradiol gel (PEG) on hemodynamics in postmenopausal Korean women with grade 1 hypertension. Methods Fifty-two postmenopausal women (aged 49–75 years) with systolic BP (SBP) of 140–160 mmHg or diastolic BP (DBP) of 90–100 mmHg were randomly assigned for 12 weeks to placebo (n = 16), estrogen therapy (ET) (n = 19) with PEG (0.1 %, 1 g./d), or estrogen + progestogen therapy (EPT, n = 17) with PEG and MP4 (100 mg/d). The primary endpoint was ambulatory BP and the secondary endpoints were arterial stiffness as brachial–ankle pulse-wave velocity (baPWV) and aortic parameters on applanation tonometry. Results One woman in the ET group dropped out, so 51 participants were finally analyzed. Outcome measures for ambulatory BP and arterial stiffness were not different between groups. Within-group comparisons showed that EPT significantly decreased daytime heart rate and baPWV: the changes from baseline (mean ± standard deviation) were − 2.5 ± 5.7 bpm (P = 0.03) and − 0.6 ± 1.4 m/s (P = 0.04), respectively. After adjusting for baseline, linear regression analysis revealed a significant difference in the relationship between baseline and 12-week baPWV among groups (P = 0.02). The relationship was significantly different between placebo and ET (P = 0.03) and EPT (P = 0.01), respectively, but not between ET and EPT. Additionally, pooled results of active treatments disclosed that SBP, DBP, PWV, and augmentation index at the aorta were significantly reduced relative to baseline. Conclusions There was no difference in ambulatory BP between ET and EPT in postmenopausal Korean women with grade 1 hypertension. Further, ET and EPT similarly decreased baPWV from baseline as compared with placebo. MP4 might not adversely influence estrogen effects on ambulatory BP and arterial stiffness.

Abstract
The results of the WHI, which reported a doubling of the risk of Alzheimer's disease (AD) and a decline in cognitive function in women who were given menopause hormone therapy (MHT), have raised concerns on the deleterious impact of MHT on the central nervous system. Such as for the cardiovascular system, the very late age of initiation of treatment and the nature of the molecules have led to conclusions that cannot be extended to women in their fifties, at the onset of their menopause which is the usual age of MHT initiation. The molecules, which are used in France, 17-beta estradiol and natural progesterone (or its isomer, dydrogesterone) are very different from the equine conjugated estrogens and medroxyprogesterone acetate used in the WHI. It can now be stated that if MHT is started within the window of opportunity (i.e. before the age of 60 or within the first 10years after the beginning of menopause) no deleterious effect on cognition is observed. Moreover, cognition remains relatively stable at the beginning of menopause since the cognitive reserve as well as the different compensation circuits allow compensation for estrogen deficiency. This does not in any way prejudge a possible positive effect of MHT on AD, which is very difficult to demonstrate, as the age of onset of this dementia is very late, 20 or 30years after the initiation of treatment.

Abstract
OBJECTIVES To analyze the oncologic outcomes of long-term fertility-sparing treatment (FST) in patients with early-stage endometrial cancer (EC) and to determine the optimal duration of FST that would not hamper survival outcomes. METHODS Patients undergoing FST for presumed stage IA, grade 1 EC between 2005 and 2018 were retrospectively analyzed. Oncologic outcomes were compared between the group with ≤6 months of FST and the group with >6 months of FST. Segmented regression analysis was used to estimate the dynamic changes in cumulative complete response (CR) rates according to FST duration. RESULTS A total of 122 patients received oral progestin, with concurrent levonorgestrel-releasing intrauterine device use in 108 (88.5%) and 105 (86.1%) achieved CR with a median time to achieve CR of 10 (3-42) months. Of the patients not achieving CR at 6 months of FST, 95.1% (78/82) continued further FST. The overall CR rate (88.9% [32/36] vs. 84.9% [73/86], P = 0.436] was not significantly different between the groups with ≤6 and > 6 months of FST. The changes in cumulative CR rates were significantly different between the two segments divided by 15 months from the initial FST (P = 0.0015, segmented regression analysis). The overall progressive disease (PD) rate was 3.3% (4/122), and PD was first detected during 9-12 months of FST. CONCLUSION Patients not achieving CR and not showing PD at 6 months of FST could continue further FST. If disease progression is excluded, 15 months of FST can be considered as the cutoff for the optimal FST duration.

Abstract
BACKGROUND Endometriosis affects the responsiveness to ovarian stimulation. This study aimed to assess the role of Dienogest pretreatment for endometriosis suppression as compared to Gonadotropin-releasing hormone agonist (GnRHa) in patients with endometriosis pursuing IVF treatment. METHODS In this randomized controlled trial, 134 women with endometriosis-related infertility were randomly allocated to group A (n = 67) who had monthly depot GnRHa for 3 months before ovarian stimulation in IVF treatment (Ultra-long protocol), and Group B (n = 67) who had daily oral Dienogest 2 mg/d for 3 months before starting standard long protocol for IVF. The primary outcome measure was the number of oocytes retrieved. The secondary outcome measures included the number of mature oocytes, fertilization rate, quality of life assessed by FertiQoL scores, cost of treatment, and pregnancy outcomes. RESULTS Although there was no statistically significant difference between both groups regarding ovarian stimulation, response parameters, and pregnancy outcomes, the Dienogest group had a lower cost of treatment (2773 vs. 3664 EGP, P < 0.001), lower side effects (29.9% vs. 59.7%, P < 0.001), higher FertiQoL treatment scores (33.2 vs. 25.1, P < 0.001) and higher tolerability scores (14.1 vs. 9.4, P < 0.001 < 0.001). CONCLUSION Our study indicates that Dienogest is a suitable and safe substitute for GnRHa pretreatment in endometriosis patients.

Abstract
BACKGROUND Endometriosis is one of the most common diseases in women of reproductive age. Despite characteristic symptoms such as dysmenorrhea, chronic abdominal pain, dysuria, dyschezia and dyspareunia, the average latency until diagnosis is around 10 years. In addition to the individual limitations, the disease also has economic and health policy relevance. The complaints are followed by reductions in working hours, cyclically recurring short-term sick leave or presenteeism with reduced performance. OBJECTIVE An overview of the main recommendations of the S2k guideline on the diagnosis and treatment of endometriosis. MATERIAL AND METHODS For the S2k guideline "Diagnostics and therapy of endometriosis", a systematic literature search was conducted in PubMed and Cochrane according to a defined algorithm and over a period of more than 5 years, from 01.01.2014 to 31.12.2018. For the evaluation, 322 publications, including systematic reviews, meta-analyses and randomized controlled trials were considered and these were assessed by 41 mandate holders and representatives from 25 Association of the Scientific Medical Societies in Germany (AWMF) and non-AWMF professional societies, organizations, associations and working groups of the German Society for Gynecology and Obstetrics (DGGG), as well as two patient target groups. RESULTS In a structured consensus process, 48 recommendations and 27 statements were formulated, which are presented in extracts in this paper. DISCUSSION Interdisciplinary cooperation is essential in the treatment of patients with (suspected) endometriosis. This team should include all necessary disciplines in a cross-sectoral network. This is most likely to be achieved in a certified structure.

Abstract
Arginine vasotocin (VT) is the basic neurohypophysial nonapeptide hormone in teleosts. VT is also distributed in the ovary of the catfish Heteropneustes fossilis and induces final oocyte maturation (FOM) and ovulation by stimulating the maturation-inducing hormone (MIH). The present study reports the effects of cAMP (0.5 mM), phosphodiesterase inhibitors (IBMX -0.5 mM and theophylline- 0.5 mM), the inositol triphosphate (IP3) receptor inhibitor heparin (10 μg/mL) and the Ca2+ chelator BAPTA-AM (25 μM) on VT (100 nM) - induced progestin stimulation, FOM and ovulation. Incubation of post-vitellogenic follicles with cAMP, IBMX and theophylline for 0, 8, 16 and 24 h stimulated basal secretion of progesterone (P4), 17-hydroxyprogesterone (17-P) and 17, 20β-dihydroxy-4-pregnen-3-one (MIH) in a duration-dependent manner. The incubation of the follicles with heparin stimulated P4 modestly, and 17-P and MIH levels in a duration-dependent manner. The incubation of the follicles with BAPTA-AM stimulated P4 and MIH levels marginally and 17-P robustly. The stimulation was in the order cAMP > IBMX > theophylline > heparin > BAPTA-AM. The incubation of the follicles with VT stimulated P4, 17-P, MIH, GVBD and ovulation in a duration-dependent manner. The co-incubations with VT and the test compounds inhibited the VT-induced stimulation of P4, 17-P and MIH levels in a time-dependent manner in the order heparin > BAPTA-AM > cAMP > IBMX > theophylline. Concurrently, the VT-induced stimulation of GVBD and ovulation were also inhibited by the test compounds in the same order. The results show that VT induces FOM and ovulation preferentially acting through Ca2+ pathway and a crosstalk between Ca2+ and cAMP signaling pathways seems to integrate the processes.

Abstract
This study evaluated the role of progesterone (P4) and medroxyprogesterone acetate (MAP) on the molecular status of immature cumulus-oocyte complexes (COCs) and the implications for oocyte quality in sheep. The number of viable COCs per ewe and the rate of COCs screened for developmental competence by brilliant cresyl blue positive (BCB+) were similar (P > 0.05), respectively, across treatments (P4: 7.7 ± 0.7 and 4.7 ± 1.2; MAP: 5.7 ± 1.0 and 3.5 ± 2.3; and control: 5.7 ± 1.1 and 3.6 ± 2.4). The COCs' gene expression was altered by exogenous progestogens compared with the control group: markers of steroidogenic pathway (FSH receptor [FSHr], LH receptor [LHr], and estradiol receptor α) and of quality (zygote arrest 1, growth differentiation factor 9, and B-cell lymphoma 2) were in abundance in P4 (P < 0.05). In addition, reelin protein (RELN) was downregulated, and Bcl-2 was upregulated in MAP (P < 0.05). In the P4 vs MAP comparison, FSHr, LHr, and RELN genes were upregulated (P < 0.05) in the P4 group. In conclusion, P4 and MAP promoted dissimilar effects on transcriptome profiling of immature BCB-selected COCs, possibly due to the differences in the chemical structure of progestogens and concentrations of serum P4. Exogenous P4 impacted positively on the profile of genes related to oocyte quality.

Abstract
Antiretroviral therapy has slowed the HIV/AIDS pandemic and is currently being used as a prophylactic measure for individuals at high risk of infection. However, concerns over adverse effects of long-term use need to be explored. We hypothesize that this may occur, at least in part, through off-target effects via select steroid receptors (SRs) that broadly regulate multiple physiological processes. We investigated the effects of maraviroc (MVC), tenofovir disoproxil fumarate (TDF), and dapivirine (DPV) on progesterone receptor B (PR-B) transcriptional activity. We found that MVC and TDF activate PR-B transcription in the absence of progestogens on a PR-regulated promoter reporter construct and on endogenous PR-regulated genes. MVC and TDF exhibited no direct binding to PR-B; however, increased PR-B phosphorylation was detected with TDF but not MVC. DPV transactivated gilz and ptgs2 in the absence of progestogens and exhibited PR-B binding while showing no effects on phosphorylation, suggesting that it may activate PR-B through a direct mechanism. Our study shows that potential off-target immunomodulatory effects of MVC, TDF and DPV occur in vitro and these are most likely mediated by different mechanisms of PR-B activation.

Abstract
Among young persons, ease of use, high efficacy, and high acceptability makes the etonogestrel contraceptive implant an important choice for this age group. Adolescent-friendly, patient-centered counseling considers the patient's cognitive development, the influence of friends and family, as well as their own preferences and values. Age-appropriate language, graphics, and models are useful to explain contraceptive options and relevant side effects. Effectiveness, reversibility, safety, noncontraceptive benefits, and side effects are important attributes and should be discussed when teens are choosing a contraceptive method. In this review we describe suggested best practices for counseling adolescents about the etonogestrel implant so they can make informed, prudent decisions about using this contraceptive method.

Abstract
Different progestogens are widely used in hormonal therapy and mediate their therapeutic actions via the progesterone receptor (PR). Little published data exist on their relative efficacies and potencies via the PR, while those available may be confounded by off-target receptors, different methodologies and model systems. We performed dose-response analysis to investigate the efficacies and potencies for transcription of progesterone and several progestins widely used in contraception via the B isoform of human PR (PR-B). We compared responses using three different cell lines and two different transient transfection conditions. Results show that in vitro biological responses via PR-B for the select progestogens can vary significantly in biocharacter, rank order and absolute values for efficacies and potencies, depending on the cell line and transfection condition. Progestogen rank orders for published relative binding affinities are mostly different to those for relative efficacies and potencies. These in vitro differences suggest that rank orders and absolute values of the efficacies and potencies of the progestogens are likely to vary in vivo in a cell-specific and progestogen-specific manner, and cannot easily be extrapolated from in vitro data, as is usually the practice. While obtaining such data in vivo is not possible, these in vitro data show proof of concept for likely significant cell- and progestogen-specific PR-B effects.

Abstract
PURPOSE Deep infiltrating endometriosis (DIE) is associated with severe pelvic pain and functional impairment of bowel, urinary, and sexual functions. Though hormone therapy with progestins, either as single agents or combined with estrogens, is effective in managing symptoms, some patients may experience a suboptimal response. Endometrial thickness assessed by transvaginal ultrasound examination, reflecting the overall estrogen stimulation, may correlate with the clinical response to hormonal treatments. METHODS A retrospective study was carried out on 61 women with DIE affecting the bowel or the recto-vaginal septum, undergoing hormone treatment. The symptoms of patients were evaluated at the baseline and after 12 months of therapy, calculating a global Visual Analogue Scale score (gVAS) encompassing dysmenorrhea, dyspareunia, chronic pelvic pain, dyschezia, abdominal pain and dysuria. Patients were divided into two subgroups using, as a calculated cut-off value, the mean endometrial thickness in our population at 12 months. The change in gVAS score during the 12 months of treatment was then compared between the two groups. RESULTS Women with a thinner endometrium (< 3.3 mm) showed a better response to treatment in terms of symptoms control as compared to patients with a thicker endometrium (mean gVAS score reduction 9.2 ± 1.3 vs. 5.2 ± 1.3, p = 0.036). The correlation between endometrial thickness and symptomatic response was also confirmed (p = 0.041) on multivariate linear regression analysis including as covariates age, size of lesions of DIE, presence of uterine adenomyosis, ovarian endometriosis and type of medical treatment. CONCLUSION Endometrial thickness on ultrasound transvaginal examination is correlated with better response rates to hormone therapy in terms of symptoms control. A thinner endometrium, probably resulting from a more efficient suppression of estrogen stimulation, is associated with improved symptoms. These results may aid clinicians in monitoring and tailoring hormonal treatments during follow-up of women with symptomatic DIE.

Abstract
Progesterone and its related molecules are a crucial tool in modern clinical practice, particularly in the fields of reproductive medicine. Its history is old, but still under development. Presently, the pharmacokinetic and pharmacodynamic profiles of progesterone is well-known and knowledge on natural progesterone (P4) and other molecules with progestational activity, namely progestogens or gestagens, are improved and their interest is still alive. Topics of great and current interest are progesterone and its role in assisted reproductive protocols, threatened and recurrent pregnancy loss, threatened preterm birth with favorable results on pregnancy, and perinatal outcomes. Moreover, progesterone provides several other positive effects on women's health. This paper describes the main chronological steps that characterized the history of progesterone, where scientific research and clinical practice are arrived and WHICH are the future perspectives on this hormone with a "never-ending history."

Abstract
PURPOSE To examine whether there is a positive association between sexual dysfunction (SD) and different types of progestin-based contraceptives. METHODS Nested case-control study in women of child-bearing age (15-45 years) from the IQVIA® Ambulatory electronic medical record database from 2008 to 2018. Cases defined by diagnosis of sexual dysfunction identified by international classification for disease clinical modification code 9th and 10th. Each case was matched to four controls and rates of prescriptions of the following were compared: levonorgestrel intra-uterine device (IUD), progestin, and ethinyl estradiol (EE) combined oral contraceptive (COC) formulations including levonorgestrel, norgestimate, drospirenone, desogestrel, norethindrone, and norgestrel; etonogestrel vaginal ring; and medroxyprogesterone injection. RESULTS Overall, 6689 cases of patients with SD were matched to 26,756 matched controls. Compared with matched controls, more subjects with SD used levonorgestrel IUD (OR 1.24, 95% CI 1.08-1.44), EE-levonorgestrel COC (OR 1.18, 95% CI 1.00-1.41), EE-drospirenone (OR 1.28, 95% CI 1.00-1.67), and medroxyprogesterone (OR 1.38, 95% CI 1.12-1.70). The use of norgestrel exhibited a protective effect (OR 0.83, 95% CI 0.73-0.95). When using the EE-levonorgestrel COC as a comparator, norgestrel users exhibited a protective effect (OR 0.70, 95% CI 0.57-0.87) while no other contraceptives showed a statistically significant difference in association with SD. CONCLUSION Our study found an increase in the use of levonorgestrel (COC and IUD), drospirenone, and medroxyprogesterone in subjects with SD. The risk of contraceptives did not differ when compared with oral levonorgestrel. The small association size and lack of difference between drug formulations suggest a minimal impact of progestin-based contraceptives on sexual dysfunction.

Abstract
Peri- and postmenopausal disorders can have a significant impact on quality of life. Hormone replacement therapy (HRT) might be necessary in order to decrease women's symptoms. The German S3 guideline "Peri- and Postmenopause-Diagnostics and Therapy" (2020) provides recommendations that include the most recent evidence as well as the Women's Health Initiative (WHI) study results from 2002 and 2004. These results led to reduced prescription patterns due to a high risk of cardiovascular diseases as well as an increased risk for breast cancer if HRT had been administered. Both ongoing analyses of subgroups and other studies extenuated the WHI data, since the increased risks were neither generalizable to the typical postmenopausal patient (regarding age and risk profile) nor to the medication being used today. This article summarizes all aspects of HRT in peri- and postmenopausal women (indications, contraindications, practical approaches, risks, prevention) and provides recommendations with respect to the most recent S3 guideline.

Abstract
This chapter discusses the mechanisms of action of hormonal male contraception, which suppresses the hypothalamic-pituitary-testis axis. When the intratesticular concentration of testosterone is subsequently suppressed to adequately low concentrations, spermatogenesis is arrested. Androgens are a necessary hormonal male contraceptive component because they not only suppress the hypothalamic-pituitary-testis axis, but also provide the male hormone necessary to maintain peripheral androgen functions. Past studies using testosterone alone and testosterone combined with progestins demonstrated contraceptive efficacy in the female partner at rates similar to combined hormonal female methods. Newer hormonal male contraceptive formulations and the alternative routes of administration are discussed, along with potential barriers, challenges, and opportunities for hormonal male contraceptive development. Novel methods that are safe, effective, reversible, user-friendly, and coitus-independent are intrinsic to equitably meet the various needs and limitations of an increasingly diverse population.

Abstract
This experiment was designed to evaluate breeding strategies involving natural service or fixed-time artificial insemination (FTAI) in Bos indicus-influenced beef heifers (n = 1456) when there were field-type management conditions. Body weights and reproductive tract scores (RTS; Scale 1-5) were obtained for heifers before assignment to one of five treatments: 1) Non-synchronized control exposed for natural service (NS), n = 299; 2) melengestrol acetate + natural service (MGA + NS; 0.5 mg/heifer/d), n = 295; 3) 14-d controlled internal drug release insert + natural service (CIDR + NS), n = 289; 4) 14-d MGA-prostaglandin F2α (PG) + FTAI, n = 295; or 5) 14-d CIDR-PG + FTAI, n = 278. Fertile bulls were placed in pastures with heifers of the three NS treatment groups for a 65-day period which began 10 days after progestin treatments (MGA or CIDR) ended. Heifers in FTAI treatment groups were administered PG (25 mg, IM) 16 days after CIDR removal or 19 days following MGA withdrawal, respectively, and FTAI was performed at 66 (CIDR-PG) or 72 h (MGA-PG) after PG. Gonadotropin-releasing hormone (GnRH; 100 μg, i.m.) was administered at FTAI. Pregnancy status was determined at the end of a 65-day breeding period. Pregnancy rates on Days 21 and 65 of the breeding period differed among treatment groups based on pre-treatment pubertal status (P ≤ 0.02) and body weight (P ≤ 0.05) but did not differ by group. These data highlight the need for continued research efforts to improve reproductive management of Bos indicus-influenced females.

Abstract
A variety of structurally and functionally distinct progestins is used in contraception and menopausal hormone therapy (MHT). Some progestins elicit off-target effects by binding to steroid receptors other than the progesterone receptor, which may impact their therapeutic and side-effect profiles. We directly compared the binding affinities, efficacies and potencies of selected progestins via the mineralocorticoid receptor (MR). We did not detect a significant difference in the affinities of medroxyprogesterone acetate (MPA), norethisterone acetate (NET-A), levonorgestrel (LNG), gestodene (GES), etonogestrel (ETG), nestorone (NES) and nomegestrel acetate (NoMAC) for the MR, while these were significantly lower compared to drospirenone (DRSP). While GES and NoMAC display affinities indistinguishable from progesterone (P4), the binding affinity of DRSP is significantly greater and all other progestins significantly lower than that of P4. Dose-response analyses showed that P4, GES and ETG display indistinguishable MR antagonist potencies for transactivation to the well-known MR antagonist spironolactone, while LNG, NoMAC and DRSP are significantly more potent than spironolactone and MPA, NET-A and NES are significantly less potent. Similar to our previous findings for NET-A, we show that LNG, GES, ETG and NES dissociate between transactivation and transrepression via the MR. Together our results provide strong evidence for progestin- and promoter-specific transcriptional effects via the MR, which are poorly predicted by relative binding affinities. A comparison of the binding affinities and potencies with reported free serum concentrations of progestins relative to the endogenous mineralocorticoid aldosterone, suggest that all progestins except MPA, NET-A and NES will likely compete with aldosterone for binding to the MR in vivo at doses used in hormonal therapy to elicit physiologically significant off-target effects.

Abstract
Fish are exposed to progestins and steroid mixtures in contaminated waters but the ecotoxicological implications are not sufficiently known. Here we analyze effects of the new generation progestin dienogest (DNG) followed by investigating effects of mixtures of new generation progestins containing DNG, cyproterone acetate and drospirenone and the hormone progesterone. Furthermore, effects of this mixture were studied after adding 17β-estradiol (E2) and clobetasol propionate (CLO) in zebrafish embryos and larvae at concentrations between 0.01 and 10 μg/L. DNG showed only very minor transcriptional alterations among the 24 assessed genes with downregulation of the fshb transcript only. The progestin mixture caused weak induction of the lhb, cyp2k22 and sult2st3 transcripts. Addition of E2 to the mixture caused strong induction vtg1, cyp19b, esr1 and lhb, as well as downregulation of fshb from 0.01 μg/L onwards. Besides altering the same transcripts, addition of CLO altered glucocorticoid regulated genes mmp-9, mmp-13, g6pca, fkbp5 and irg1l. While each steroid class exhibited its specific activity independently in the mixture, sult2st3 and cyp2k22 were regulated by both E2 and CLO. Furthermore, CLO alone and in mixtures decreased spontaneous muscle contractions, increased heartrate and induced edema. Our study highlights the prominent effects of E2 and CLO in environmental steroid mixtures, while new generation progestins show relatively low activity.

Abstract
There is increasing evidence that reproductive hormones exert regulatory effects in the central nervous system that can influence behavioral, cognitive, perceptual, affective, and motivational processes. These effects occur in adults and post-pubertal individuals, and can be demonstrated in humans as well as laboratory animals. Large changes in 17β-estradiol and progesterone occur over the ovarian cycle (i.e., the menstrual cycle) and afford a way for researchers to explore the central nervous system (CNS) effects of these hormones under natural physiological conditions. Increasingly, oral contraceptives are also being studied, both as another route to understanding the CNS effects of reproductive hormones and also as pharmacological agents in their own right. This mini-review will summarize the basic physiology of the menstrual cycle and essential facts about oral contraceptives to help novice researchers to use both paradigms effectively.
