FSH Part 2

As a woman nears perimenopause, the number of small antral follicles recruited in each cycle diminishes and consequently insufficient Inhibin B is produced to fully lower follicle stimulating hormone (FSH) and the serum level of FSH begins to rise. Eventually the FSH level becomes so high that down regulation of FSH receptors occurs and by menopause any remaining small secondary follicles no longer have FSH receptors. Continue reading

FSH Part 1

Follicle-stimulating hormone (FSH) is a hormone found in humans and other animals. It is synthesized and secreted by gonadotrophs of the anterior pituitary gland. FSH regulates the development, growth, pubertal maturation, and reproductive processes of the body. FSH and luteinizing hormone (LH) act synergistically in reproduction. Specifically, an increase in FSH secretion by the anterior pituitary causes ovulation. Continue reading
