Explore the function and hormonal regulation of the gonads in this biology lecture on the endocrine system. Learn about the hypothalamic-pituitary-gonadal axis, including the role of gonadotropin-releasing hormone (GnRH) from the hypothalamus and follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary. Discover how these hormones interact with the ovaries to produce estrogen and progesterone, and with the testes to produce testosterone and dihydrotestosterone (DHT). Gain valuable insights for MCAT, DAT, NEET, and other medical entrance exams through this comprehensive overview of gonadal endocrinology.
