Abstract
Progestins are used to treat some hormone-sensitive tumors. This review discusses the mechanisms of progestins' effects on tumor cells, the differences in the effects of progesterone and its analogs on different tumor types, and the influence of progestins on the antitumor immune response. Progestins cause a cytostatic effect, but at the same time they can suppress the antitumor immune response, and this can promote the proliferation and metastasis of tumor cells. Such progestins as dienogest, megestrol acetate and levonorgestrel increase the activity of NK-cells, which play a major role in the body's fight against tumor cells. The use of existing progestins and the development of new drugs with gestagenic activity may hold promise in oncotherapy.

Reprod Sci 2023; 30:3037-3045.

Abstract
We conducted a double-blind, randomized, placebo-controlled clinical trial to evaluate the efficacy of oral dydrogesterone (DG) on maternal and neonatal consequences in the treatment of preterm labor. We included 100 nulliparous mothers (24-34 weeks) with normal pregnancy who had preterm labor pain. Participants who received magnesium sulfate were randomly assigned to the investigation group (DG 30 mg/day) or placebo group. Maternal and neonatal outcomes were compared between the two groups. Recurrent uterine contraction (UC) rates (92% vs. 88%, P = 0.862) and the incidence of preterm delivery (66% vs. 58%, P = 0.834) were not different in the DG and placebo groups. No significant differences were observed in terms of gestational age at delivery (33.5 ± 3.5 vs. 34.2 ± 3.2, P = 0.281), latency period (5.53 ± 2.29 days vs. 5.59 ± 2.57 days, P = 0.622), cervical dilation (1.82 ± 0.26 cm vs. 1.84 ± 0.29 cm, P = 0.281), and effacement (53 ± 4.47% vs. 57.21 ± 6.27%, P = 0.622) between the placebo and DG groups. The percentage of neonates with a 1-min Apgar score < 7 was higher in the placebo group compared with that of the DG group (12% vs. 0%, P = 0.0001). However, both groups were similar in the frequency of a 5-min Apgar score < 7. No differences in the term of adverse effects of medications were recorded. Our results showed that DG adjuvant to magnesium sulfate could not be effective in improving the incidence of preterm labor, rate of recurrent UC, latency period, pregnancy outcomes, and maternal and neonatal outcomes when compared with the placebo group.

Abstract
Higher mammographic breast density in premenopausal and postmenopausal women is related to a higher breast cancer risk. In this review, we analyze the correlation between estrogen, progesterone, and mammographic density in postmenopausal women and clarify whether these findings are consistent across different types of mammographic breast density. We extracted data concerning mammographic density increases in the populations treated with estrogen-only hormone replacement therapy and those treated with estrogen and progestin hormone replacement therapy. Postmenopausal women treated with estrogen and progesterone regimens had a statistically significant lesser mammographic density increase than estrogen-only hormone replacement therapy regimens.

Abstract
OBJECTIVES Progesterone, a sex steroid, is measured in serum by immunoassay in a variety of clinical contexts. One potential limitation of steroid hormone immunoassays is interference caused by compounds with structural similarity to the target steroid of the assay. Dydrogesterone (DYD), an orally active stereoisomer of progesterone, is used for various indications in women's health. Herein, we report a systematic in vitro investigation of potential interference of DYD and its active metabolite 20α-dihydrodydrogesterone (DHD) in seven widely used, commercially available progesterone assays. METHODS Routine human plasma samples were anonymized and pooled to create three graded concentration levels of progesterone (P4 high, P4 medium, P4 low). Each pooled P4 plasma sample (6-7 mL) was spiked at high, medium, and "none" concentration with DYD/DHD and was divided into 0.5 mL aliquots. The blinded aliquots were analyzed by seven different laboratories with their routine progesterone assay (six different immunoassays and one liquid chromatography-tandem mass spectrometry assay, respectively) within the Dutch working group on endocrine laboratory diagnostics of the Dutch Foundation for Quality Assessments in Medical Laboratories. RESULTS The sample recovery rate (P4 result obtained for sample spiked with DYD/DHD, divided by the result obtained for the corresponding sample with no DYD/DHD × 100) was within a ±10% window for the medium and high P4 concentrations, but more variable for the low P4 samples. The latter is, however, attributable to high inter- and intra-method variability at low P4 concentrations. CONCLUSIONS This study does not indicate any relevant interference of DYD/DHD within routinely used progesterone assays.

Abstract
Dydrogesterone is an orally active synthetic progestogen, with a molecular structure similar to that of natural progesterone. As dydrogesterone does not inhibit ovulation at standard doses, is devoid of estrogenic or androgenic properties, and does not induce metabolic side effects, it is suitable for use throughout a woman's lifetime, from adolescence to older age, for conditions associated with altered levels of endogenous progesterone. Aside from its well established role as a component of menopausal hormone therapy, dydrogesterone is indicated in younger women for treatment of dysmenorrhea, irregular menstrual cycles, premenstrual syndrome, and threatened or recurrent miscarriage; and is effective as luteal phase support during assisted reproduction techniques. In this narrative review, evidence is examined for use of dydrogesterone across a range of disorders affecting menses and pregnancy. A case study woven into the review illustrates the clinical uses of dydrogesterone during a young woman's journey to become a mother.

Abstract
INTRODUCTION Hormone replacement in females with hypogonadism is advocated to address the various clinical aspects of estrogen deficiency. AREAS COVERED This article focuses on hormone replacement in young females with hypogonadism, including a rationale as to why hormone replacement in such patients differs from treatment in postmenopausal females, a summary of symptoms encountered by females with hypogonadism and a comprehensive discussion of the various treatment options available, specifically focusing on the latest advances in the subject. A Medline search was conducted using different combinations of relevant keywords, giving preference to recent publications. EXPERT OPINION Whilst traditionally oral contraceptive pills (containing ethynyl estradiol) were commonly used as a form of hormone replacement, it is now increasingly recognized that this is not the optimal treatment option. Physiological hormone replacement with transdermal estradiol is found to be superior. Evidence suggests that micronized progesterone may be associated with fewer side effects, although its effect on endometrial protection is not yet proven. Synthetic progestins confer varying degrees of androgenic and thromboembolic properties which should be kept in mind when prescribing individualized treatment. Further studies in different sub-cohorts of female patients with hypogonadism might help address the specific needs of individual patients.

Abstract
Transdermal estradiol (TE) application (using gels, patches or a novel spray) is now a preferred route of hormone therapy (HT) in menopausal women, because various risks such as venous thromboembolism, stroke and unwanted hepatic effects can be reduced compared with oral HT. However, in the presence of an intact uterus, concurrent administration of progestogen is needed for endometrial protection. Due to the variety of progestogens available and differences in their clinical effects, the selection of the most appropriate substance and dosing for individual combination therapy can be difficult. This is especially true for TE gels and the novel spray because no fixed combination products are commercially available, meaning all progestogens must be added separately, and even for patches only two transdermal synthetic progestogens are available. The aim of this review was to summarize data on the endometrial effects of the different progestogens and to provide practical recommendations for the choice of progestogen (type and dosing), with a focus on endometrial protection when using TE, especially when using the novel estradiol (E2) spray.

Abstract
Stroke is a worldwide epidemic disease with high morbidity and mortality. The continuously exploration of anti-stroke medicines and molecular mechanism has a long way to go. In this study, in order to screen candidate anti-stroke compounds, more than 60000 compounds from traditional Chinese medicine (TCM) database were computationally analyzed then docked to the 15 known anti-stroke targets. 192 anti-stroke plants for clinical therapy and 51 current anti-stroke drugs were used to validate docking results. Totally 2355 candidate anti-stroke compounds were obtained. Among these compounds, 19 compounds are structurally identical with 16 existing drugs in which part of them have been used for anti-stroke treatment. Furthermore, these candidate compounds were significantly enriched in anti-stroke plants. Based on the above results, the compound-target-plant network was constructed. The network reveals the potential molecular mechanism of anti-stroke for these compounds. Most of candidate compounds and anti-stroke plants are tended to interact with target NOS3, PSD-95 and PDE5A. Finally, using ADMET filter, we identified 35 anti-stroke compounds with favorable properties. The 35 candidate anti-stroke compounds offer an opportunity to develop new anti-stroke drugs and will improve the research on molecular mechanism of anti-stroke.

Abstract
1. The metabolism of dydrogesterone was investigated in human liver cytosol (HLC) and human liver microsomes (HLM). Enzymes involved in dydrogesterone metabolism were identified and their relative contributions were estimated. 2. Dydrogesterone clearance was clearly higher in HLC compared to HLM. The major active metabolite 20α-dihydrodydrogesterone (20α-DHD) was only produced in HLC. 3. The formation of 20α-DHD by cytosolic aldo-keto reductase 1C (AKR1C) was confirmed with isoenzyme-specific AKR inhibitors. 4. Using recombinantly expressed human cytochrome P450 (CYP) isoenzymes, dydrogesterone was shown to be metabolically transformed by CYP3A4 and CYP2C19. 5. A clear contribution of CYP3A4 to microsomal metabolism of dydrogesterone was demonstrated with HLM and isoenzyme-specific CYP inhibitors, and confirmed by a significant correlation between dydrogesterone clearance and CYP3A4 activity. 6. Contribution of CYP2C19 was shown to be clearly less than CYP3A4 and restricted to a small group of human individuals with very high CYP2C19 activity. Therefore, it is expected that CYP2C19 genetic variations will not affect dydrogesterone pharmacokinetics in man. 7. In conclusion, dydrogesterone metabolism in the liver is dominated primarily by cytosolic enzymes (particularly AKR1C) and secondarily by CYP3A4, with the former exclusively responsible for 20α-DHD formation.

Abstract
Dydrogesterone is widely used for menstrual disorders, endometriosis, threatened and habitual abortion and postmenopausal hormone replacement therapy. Although progestins have a promiscuous nature, dydrogesterone does not have clinically relevant androgenic, estrogenic, glucocorticoid or mineralocorticoid activities. To date, systematic biochemical characterization of this progestin and its active main metabolite, 20α-dihydrodydrogesterone, has not been performed in comparison to progesterone. The objective of this study was to evaluate the selectivity and potential androgenic/antiandrogenic effects of dydrogesterone and its metabolite in comparison to progesterone and medroxyprogesterone acetate by analyzing their interference with AR signaling in vitro. We characterized dydrogesterone and its metabolite for their binding and transactivation of androgen and other steroid hormone receptors and for their potential inhibitory effects against androgen biosynthetic enzymes, 17β-hydroxysteroid dehydrogenase types 3 and 5 and 5α-reductase types 1 and 2. We found that dydrogesterone resembled progesterone mainly in its progestogenic effects and less in its androgenic, anti-androgenic, glucocorticoid and antiglucocorticoid effects; whereas, 20α-dihydrodydrogesterone showed reduced progestogenic potency with no androgenic, glucocorticoid and mineralocorticoid effects. Effects on the androgen and glucocorticoid receptor differed depending on the technology used to investigate transactivation. Progesterone, but not dydrogesterone and 20α-dihydrodydrogesterone, exerted anti-androgenic effects at the pre-receptor level by inhibiting 5α-reductase type 2. Dydrogesterone, 20α-dihydrodydrogesterone and progesterone inhibited the biosynthesis of testosterone catalyzed by 17β-hydroxysteroid dehydrogenase types 3 and 5; however, due to their micromolar K(i) values, these activities appeared to be not of relevance at therapeutic levels. Overall, our data show that the anti-androgenic potential of dydrogesterone and 20α-dihydrodydrogesterone is less pronounced compared to progesterone.
