Summary: A novel missense mutation (I423T) in the FSHR second transmembrane domain was identified in a woman with primary ovarian failure, leading to impaired receptor expression and signaling. Meanwhile, the D408Y mutation severely affected membrane expression and signal transduction. Molecular dynamics simulations showed important disruptions in both mutant FSHRs, explaining the differences in expression levels, signaling, and phenotypic expression between I423T and D408Y mutant FSHRs.

Summary: This review assesses the effectiveness of various therapies in recovering ovarian function in patients with primary ovarian insufficiency (POI) and explores a comprehensive evaluation method. The results indicate a lack of scientific evidence supporting any therapy in effectively restoring ovarian function in patients with POI.

Summary: The study found that rFSH-alfa group had higher number of retrieved oocytes, transferable embryos, fresh embryo transfer rate, and multiple birth rate compared to the uFSH group. However, both groups had similar pregnancy rates and LBR per transfer cycle, with rFSH-alfa group achieving higher CLBR per started cycle. This suggests that rFSH-alfa might produce more transferrable blastocysts and higher overall success rates compared to uFSH.

Summary: The study suggests that FSH, rather than LH, may directly stimulate the growth of androgen-independent prostate cancer. Continuous suppression of FSH during GnRH antagonist treatment may offer a therapeutic advantage over agonist in inhibiting tumor growth.

Summary: This study compared the use and clinical efficacy of three different follicle-stimulating hormones (FSHs) for follicle growth and development in long-protocol controlled ovarian hyperstimulation (COH) treatment. The results showed that the three types of FSH led to comparable growth rates of the three largest follicles and clinical pregnancy rates per fresh cycle in long-protocol COH treatment.

Summary: The study found that TPhP delayed puberty timing in mice and affected ovarian function, possibly by inhibiting estrogen receptor signaling. After 40 days of exposure to TPhP, a significant decrease in the number of follicles was observed in mice, indicating a decline in ovarian reserve.

Summary: The study investigated the impact of controlled ovarian hyperstimulation (COH) for in vitro fertilization (IVF) on thyroid function and found a significant increase in serum TSH levels during IVF, especially in women with hypothyroidism. New thyroid function screening strategies for women undergoing COH are warranted.

Summary: Translation: Despite advances in ovarian cancer therapy, recurrent OC remains a poor-prognosis disease. Targeting the follicle-stimulating hormone receptor (FSHR) with monoclonal antibodies has shown potential for treating OC and other FSHR-positive cancers, and may overcome the challenge of off-target interactions.

Summary: Recent studies have shown that the hypo-glycosylated FSH glycoform FSH21/18 is more bioactive than the fully-glycosylated FSH24. FSH21/18 predominates in women of reproductive prime while FSH24 is more common in peri-post-menopausal women. Differential FSH glycosylation modulates FSHR oligomerization, with high concentrations of FSH21/18 and FSH24 leading to dissociation of FSHR oligomers into monomers, and low concentrations promoting FSHR association into oligomers.

Summary: This study identified two novel homozygous missense variants in PANX1 associated with the oocyte death phenotype, expanding the inheritance pattern of PANX1 variants to an autosomal recessive mode. The destructive effect of these homozygous variants on PANX1 function was weaker than that of previously reported heterozygous variants, highlighting the critical role of PANX1 in human oocyte development.

Summary: This study identified three pathogenic variants in FBXO43 that are associated with early embryonic arrest in humans. By investigating the effects of these variants in cells and mouse oocytes, a causal relationship between FBXO43 and female infertility was established. These findings contribute to understanding the role of FBXO43 in human early embryonic development and provide a new genetic marker for female infertility.

Summary: This study aims to explore the potential epigenetic biomarkers associated with endometriosis (EMS) and traditional Chinese medicine (TCM) syndrome EMS types. By using reduced representation bisulfite sequencing (RRBS) and pyrosequencing methods, the researchers identified differential DNA methylation profiles and verified differentially expressed genes (DEGs) in peripheral blood samples of EMS patients with cold coagulation blood stasis (CCBS) syndrome and Qi stagnation blood stasis (QSBS) syndrome. The findings suggest that changes in DNA methylation may be associated with EMS and TCM syndrome EMS types, and the methylation level of the HDAC6 gene may be used as a distinguishing factor in QSBS-EMS patients.

Summary: This study investigated genetic risk factors for venous thromboembolism (VTE) in pregnant women through a large-scale prospective cohort study. The findings suggest that the presence of known pathogenic variants, damaging variants in thrombophilia genes, and rare damaging variants are associated with VTE in pregnancies. Exome-wide association analysis identified several genes related to basement membranes, sterol accumulation, atherosclerosis, lipid metabolism, and coagulation deficiency as potential mechanisms of VTE in pregnancies.
