Summary
Fertility in men is determined by how the testis grows during fetal and juvenile life. We recently discovered that the Sertoli cells which nurse developing sperm are highly sensitive to cross-talk between testosterone and the growth factor activin during puberty. This project studies how this cross-talk is controlled to understand how altered hormone actions in boys, including exposure to harmful endocrine disrupting chemicals, reduces adult fertility.
Polycystic ovary syndrome (PCOS) affects 5-10% of women worldwide, yet its origins remain unknown. Androgens are implicated in the development of PCOS, but the decisive, invasive studies needed to confirm and elucidate their roles are not feasible in women. Hence, using our innovative mouse models of androgen resistant female mice, this study will determine the role of androgens in PCOS aiming to better understand, and identify new treatments for this common female reproductive disorder.
