Suppressed ovarian follicle development in obese women may underlie reduced fertility

Women with obesity, even those with regular menstrual cycles, have suppressed ovarian follicle development and reduced production of reproductive hormones, which may underlie reduced fertility, according to a new study being presented Saturday at ENDO 2022, the Endocrine Society's annual meeting in Atlanta, Ga.

Anti-Müllerian hormone plays an active role in polycystic ovary syndrome

High levels of anti-Mullerian hormone (AMH) have traditionally been thought of as merely a passive byproduct of polycystic ovary syndrome (PCOS), but a new preclinical study by Weill Cornell Medicine researchers suggests that the hormone plays an active role in the disorder and may contribute to problems with ovulation and fertility.

New approach could treat infertility caused by abnormal GnRH secretion

Reports suggest that at least 25% of ovarian disorders are due to dysfunction of the brain mechanism in the hypothalamus that controls the gonadotropin-releasing hormone (GnRH), which is a molecule that governs the reproductive function in men and women by regulating the release of a range of reproductive hormones into the body, particularly gonadotropins, from the pituitary gland, which is located underneath the brain.
