F&S SCIENCE 2023; 4:302-310. [PMID: 37579932 PMCID: PMC10841328 DOI: 10.1016/j.xfss.2023.08.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/28/2023] [Revised: 08/08/2023] [Accepted: 08/08/2023] [Indexed: 08/16/2023]
Abstract
OBJECTIVE To investigate in vitro fertilization (IVF) outcomes in an adolescent transmasculine mouse model mimicking gender-affirming hormone therapy in prepubertal youth, both on testosterone (T) and after T washout. DESIGN Experimental laboratory study using a validated mouse model. SETTING University-based basic science research laboratory. ANIMAL(S) A total of 80 prepubertal 26-day-old C57BL/6N female mice were used in this study. INTERVENTION(S) Animals (n = 10/group) were implanted subcutaneously with gonadotropin-releasing hormone agonist at 3.6 mg or received sham surgery. After 21 days, they were implanted with silastic tubing containing either T 10 mg or placebo for 6 weeks. After 6 weeks, a group of animals were superovulated for immediate IVF, and another group had the implant removed and went through superovulation for IVF after 2 weeks (washout IVF). The total number of oocytes yielded, oocyte maturity rate, fertilization rate, and numbers of 2-cell embryos, 4-8-cell embryos, morula, blastocysts, and hatching blastocysts were recorded. RESULT(S) Testosterone treatment negatively impacted IVF outcomes in animals stimulated when receiving T, but not after T washout. Pretreatment with gonadotropin-releasing hormone agonist did not affect IVF outcomes. CONCLUSION(S) Although current T had a negative impact on IVF outcomes compared with controls, animals were still able to produce viable oocytes for fertilization and develop into blastocysts. Future efforts to study the impact of long-term T exposure on oocyte quality, especially aneuploidy rates, pregnancy outcomes, and live birth rates, are necessary.

Abstract
CONTEXT Base medium containing knock-out serum replacement (KSR) has been found to support formation and maintenance of follicles in one-day-old mice ovaries, but has not been shown to properly support activation and growth of primordial follicles. AIMS The present study was conducted to tailor the hormonal content of base medium containing KSR to enhance development of primordial follicles in neonatal ovaries. METHODS One-day-old mice ovaries were initially cultured with base medium for four days, and then, different hormonal treatments were added to the culture media and the culture was proceeded for four additional days until day eight. Ovaries were collected for histological and molecular assessments on days four and eight. KEY RESULTS In experiment I, the main and interactive effects of FSH and testosterone were investigated and FSH promoted activation of primordial follicles and development of primary and preantral follicles, and upregulated genes of phosphoinositide 3-kinase (Pi3k ), KIT ligand (Kitl ), growth differentiation factor 9 (Gdf9 ) and follicle stimulating hormone receptor (Fshr ) (P Bmp15 ), Connexin-43 (Cx43 ) and luteinising hormone and choriogonadotropin receptor (Lhcgr ) (P P Lhcgr (P P >0.05). CONCLUSIONS Supplementation of culture medium containing KSR with gonadotropins, particularly hMG, could improve follicular growth and expression of factors regulating follicular development. IMPLICATIONS This study was a step forward in formulating an optimal medium for development of follicles in cultured one-day-old mice ovaries.

Abstract
OBJECTIVE Sleep characteristics may potentially affect the hormonal environment related to follicular degeneration. The present study aimed to examine the association between sleep duration and the onset of menopause in Japanese women. METHODS We conducted a prospective study among 3,090 premenopausal Japanese women aged 35 to 56 years derived from participants in the Takayama Study. Habitual sleep duration was determined by a self-administered questionnaire at the baseline. Menopausal status was defined as the absence of menstruation for 12 months or more. The Cox proportional hazard model was used to estimate the hazard ratio of the occurrence of menopause for each category of sleep duration (≤6, 8, and ≥9 h) as compared with 7 hours of sleep after controlling for age, parity, body mass index, smoking status, years of education, and lifelong irregular menstrual cycle. RESULTS During the 10 follow-up years, 1,776 women experienced natural menopause. Sleep duration of ≤6 hours was significantly associated with decreased hazard ratio of menopause (0.88; 95% confidence interval, 0.78-0.99). CONCLUSIONS The data suggest that short sleep duration is associated with later onset of menopause.

Abstract
Complementary and alternative medicine (CAM) encompasses a wide range of different non-mainstream therapies that have been increasingly used for the treatment or adjunct treatment of various ailments, with premature ovarian failure (POF) being one of the most common conditions treated with CAM. This review updates the progress of CAM in the treatment of POF, and we focus specifically on reviewing the evidence for the efficacy and mechanisms of a range of CAM treatments in POF, including single herbal medicines and their active ingredients, compound Chinese medicines, acupuncture and moxibustion, psychotherapy, exercise, vitamins, massage, and dietary supplements. According to the literature, CAM is very helpful for improving POF symptoms, and we hope to provide some instructive suggestions for clinical treatment and experimental research in the future. However, more clinical trials are needed to prove the safety of CAM.

Follicle Rescue From Prepubertal Ovaries After Recent Treatment With Cyclophosphamide-An Experimental Culture System Using Mice to Achieve Mature Oocytes for Fertility Preservation. Front Oncol 2021; 11:682470.

Abstract
Ovarian tissue cryopreservation is the only feasible method for fertility preservation in prepubertal girls that will undergo gonadotoxic chemotherapy. To date, the only clinical use of cryopreserved tissue is by a later tissue retransplantation to the patient. Clinical challenges in fertility preservation of very young patients with cancer include time constraints that do not allow to retrieve the tissue for cryopreservation before starting chemotherapy and the preclusion of future ovarian tissue transplantation due to the risk of reintroduction of malignant cells in patients with systemic diseases. To overcome these two challenges, we investigated using an experimental model the feasibility of retrieving secondary follicles from ovaries of prepubertal mice after cyclophosphamide (CPA) treatment in increasing doses of 50, 75, and 100 mg/kg. The follicles were thereafter cultured and matured in vitro. The main outcomes included the efficiency of the method in terms of obtained matured oocytes and the safety of these potentially fertility preservative procedures in terms of analyses of oocyte competence regarding normality of the spindle and chromosome configurations. Our findings demonstrated that it was feasible to isolate and culture secondary follicles and to obtain mature oocytes from prepubertal mice ovaries recently treated with CPA. The efficiency of this method was highly demonstrated in the 100 mg/kg CPA group, with near 90% follicle survival rate after 12 days' culture, similarly to control. Around 80% of the follicles met the criteria to put into maturation, and more than 40% of them achieved metaphase II, with normal spindle and chromosome configurations observed. Suboptimal results were obtained in the 50 and 75 mg/kg CPA groups. These paradoxical findings towards CPA dose might probably reflect a more difficult selection of damaged growing follicles from ovaries recently treated with lower doses of CPA and a hampered ability to identify and discard those with reduced viability for the culture.

JOURNAL OF ETHNOPHARMACOLOGY 2021; 277:113789. [PMID: 33422655 DOI: 10.1016/j.jep.2021.113789] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/28/2020] [Revised: 12/28/2020] [Accepted: 01/03/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Zihuai recipe (ZHR), a Chinese herbal prescription, is widely used for the clinical treatment of Diminished ovarian reserve (DOR) infertility. However, little is known regarding its underlying mechanisms of DOR treatment. AIM OF THE STUDY This study aimed to investigate the beneficial effects of ZHR on the treatment of DOR and to reveal the underlying mechanisms. MATERIALS AND METHODS Sixty female 8-week-old Sprague-Dawley rats were randomly divided into the following six groups (n=10 per group): control, DOR, low-dose(2.7 g/kg/day) ZHR (L-ZHR), medium-dose(5.4 g/kg/day), ZHR (M-ZHR), high-dose(10.8 g/kg/day) ZHR (H-ZHR), and hormone replacement therapy (HRT) treatment groups. The DOR model was established in all the groups, except the control group, by a single intraperitoneal injection of 90 mg/kg cyclophosphamide. After the induction of the DOR model, rats were weighed and administered either the relevant dose of ZHR or an equal volume of saline solution (in the control and DOR groups). Rats in the HRT group received estradiol valerate tablets (0.16 mg/kg/day), and with medroxyprogesterone acetate tablets (0.86 mg/kg/day) added on day 4. After 32 days of treatment, the rats were euthanized and the ovaries were collected for sampling. Ovarian morphology was observed by hematoxylin and eosin staining and the number of follicles was counted under a microscope. The serum levels of anti-Müllerian hormone (AMH), gonadotropin-releasing hormone (GnRH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and estradiol (E2) were quantified by ELISA. A TUNEL assay was used to analyze the level of apoptosis of the ovarian cells. The protein expressions of p-PI3K, p-AKT, PI3K, AKT, cleaved caspase-3, BAX, and Bcl-2 were measured by western blotting and immunohistochemistry. Data analysis was performed with SPSS 20.0 software. RESULTS ZHR administration increased the ovarian index and the serum levels of AMH, GnRH, and E2, while lowering those of FSH and LH. ZHR treatment also increased the number of primordial, primary, secondary, and antral follicles, as well as the number of corpora lutea, but decreased the number of atretic follicles. Furthermore, ZHR administration decreased the percentage of TUNEL-positive ovarian cells. After treatment with ZHR, the protein expression levels of p-PI3K/PI3K, p-AKT/AKT, cleaved caspase-3 and BAX were decreased, whereas the level of Bcl-2 was increased. CONCLUSIONS ZHR improved the ovarian reserve in CTX-induced DOR rats. The mechanisms of ZHR on DOR may be mediated through the regulation of gonadal hormones of the hypothalamic-pituitary-ovarian axis (HPOA), and the inhibition of PI3K/AKT-mediated apoptosis in granulosa cells.

Moxibustion against Cyclophosphamide-Induced Premature Ovarian Failure in Rats through Inhibiting NLRP3-/Caspase-1-/GSDMD-Dependent Pyroptosis. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:8874757. [PMID: 33613687 PMCID: PMC7878072 DOI: 10.1155/2021/8874757] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/25/2020] [Revised: 01/20/2021] [Accepted: 01/21/2021] [Indexed: 11/17/2022]
Abstract
Premature ovarian failure (POF) is a clinical term used to describe a condition in which women present with amenorrhoea, hypergonadotropic hypogonadism, and infertility under 40 years old, which are mainly characterized by ovarian granulosa cell inflammation and death. Pyroptosis is a proinflammatory form of programmed cell death. However, the roles of pyroptosis in POF and moxibustion (Mox) on pyroptosis in POF have not been elucidated. The aim of the present study was to investigate the protective effect of moxibustion against cyclophosphamide- (CP-) induced POF and to determine the underlying mechanisms. The results indicated that Mox could decrease the follicle-stimulating hormone (FSH) and luteotropic hormone (LH) and increase estradiol (E2) in serum, which indicated that it could improve ovarian reserve capacity. Mox also ameliorated CP-induced ovarian injury accompanied by decreased levels of interleukin-1β (IL-1β), IL-18, and gasdermin D (GSDMD), which are key features of pyroptosis. Further investigation showed that Mox alleviated POF through NLRP3-mediated pyroptosis. On the one hand, Mox directly inhibited TXNIP/NLRP3/caspase-1 signaling-induced pyroptosis, and on the other hand, it indirectly decreased NLRP3, pro-IL-1β, and pro-IL-18 through inhibiting TLR4/MyD88/NF-κB signaling. Our results show that Mox might be a new therapeutic strategy for the treatment of POF.
