Background: The antral follicle count is a marker of ovarian reserve. Follicular Output RaTe (FORT) evaluates the proportion of follicles responsive to exogenous follicle stimulating hormone (FSH) during controlled ovarian stimulation. Our objective was to evaluate whether the diameter (AFC6: ≤ 6 mm or AFC > 6: > 6 mm) of the follicular cohort could be a predictor for ovarian responsiveness, assessed by FORT, in a prospective cohort with 92 women with IVF indication, regular cycles and no abnormality in both ovaries.
Results: The mean age (±SD) of the women was 36.03 years (± 3.87 years), the median FORT was 43.30%. We found correlation between the FORT and AFC6 (r = - 0.237, P 0.023) but not between the FORT and AFC > 6 (r = - 0.055, P 0.602).
Conclusions: The inverse correlation between FORT and AFC6 suggests that those follicles were less responsive to the exogenous FSH.

Bona fide diminished ovarian reserve or profound ovarian suppression by long-term oral contraceptive use?

Combined oral contraceptives (COCs) are widely used by reproductive-aged women. Current data suggest that long-term use of COCs can suppress ovarian reserve markers, including anti-mullerian hormone and antral follicle count, which may negatively impact ovarian response and oocyte yield in patients undergoing planned oocyte cryopreservation to preserve future reproductive potential. Discontinuation of COCs can improve ovarian stimulation outcomes, though the ideal duration of cessation is unknown.

Phthalates are known endocrine disrupting chemicals and ovarian toxicants that are used widely in consumer products. Phthalates have been shown to exert ovarian toxicity on multiple endpoints, altering transcription of genes responsible for normal ovarian function. However, the molecular mechanisms by which phthalates act on the ovary are not well understood.

Background: Sex hormones are frequently implicated in the development of cerebral small vessel disease among midlife women. However, few studies directly measure endogenous sex hormones and consider them in relation to white matter hyperintensities (WMH), indicators of cerebral small vessel disease. Further, existing work on hormones, menopause, and the brain typically focuses on ovarian estradiol (E2), with limited consideration of estrone (E1), the primary postmenopausal estrogen, or follicle stimulating hormone (FSH), an indicator of ovarian age.

Ovarian tissue cryopreservation and transplantation has emerged as a promising fertility preservation technique for individuals facing premature ovarian insufficiency due to various medical conditions or treatments. Xenotransplantation, involving the transplantation of ovarian tissue into animal hosts, has played a pivotal role in refining ovarian tissue cryopreservation and transplantation techniques and addressing key challenges. This review provides a comprehensive overview of the current landscape of ovarian tissue xenotransplantation research, focusing on its applications in investigating ovarian biology, optimizing ovarian tissue cryopreservation and transplantation protocols, and assessing safety concerns.

Objective: This study analyzed the role of traditional Chinese medicine (TCM) treatment on the cumulative live birth rate (CLBR) in women with poor ovarian response to the patient-oriented strategies encompassing individualized oocyte number (POSEIDON) criteria.
Methods: This cohort study selected 3347 patients with low ovarian response and divided them into four subgroups according to the POSEIDON criteria: Group 1 (n=947), Group 2 (n=778), Group 3 (n=164), and Group 4 (n=1458). Logistic regression analysis was used to evaluate the role of TCM treatment on the CLBR of patients with poor ovarian response to POSEIDON criteria.
