The importance of reproductive hormones, such as testosterone, estrogen, and progesterone, in regulating reproductive processes and maintaining homeostasis will be emphasized, alongside the hormonal feedback mechanisms of the hypothalamic-pituitary-gonadal (HPG) axis. The process of fertilization will be described, demonstrating the intricate coordination required for the union of sperm and egg and subsequent development of a zygote. Finally, the lesson will address common reproductive health disorders, such as endometriosis, polycystic ovary syndrome (PCOS), and infertility, and their impact on overall health and well-being.
