What are the two important cells of the gonad that produce testosterone under LH drive?
♂ Leydig cells and ♀ theca cells.
What are the two cells that secrete various hormones under FSH drive?
♂ Sertoli cells and ♀ granulosa cells.
What is the role of inhibin in the reproductive system?
Inhibin inhibits FSH secretion from the pituitary gland.
What is the role of anti-Müllerian hormone (AMH) in the reproductive system?
AMH is responsible for suppressing ♀ sex organ development during sexual differentiation in utero.
What is AMH a marker of in adult females?
Ovarian reserve.
At what age does AMH peak in females?
Early twenties.
What happens to AMH levels in females after the age of 30?
It falls from the age of 30 years onwards to undetectable levels at menopause.
