3.2.2 Normal and Disordered Feedback Mechanisms -- Male (Animation) -How do GnRH, inhibin and estradiol regulate the pituitary in males? -How do estradiol, progesterone and testoterone regulate the hypothalamus in males? -What other hormonal, neurogenic and psychogenic factors regulate the hypothalamic-pituitary unit in males? -How does orchiectomy affect plasma levels of testosterone and inhibin? -How are spermatogenesis, testosterone production, and secretion of inhibin, GnRH, FSH and LH affected by : -Orchiectomy -An FSH beta-subunit defect -An inactivating mutation of FSH receptor -High levels of prolactin (hyperprolactinemia) -Hypothalamic oligospermia -Secondary hyperthyroidism due to a hypothalamic TRH-secreting tumor -Kallman's syndrome -Secondary hypothyroidism -How is prolactin secretion affected by: -Primary hypothyroidism -TRH-secreting tumor -Secondary hypothyroidism 3.2 Objective: To describe the negative and positive feedback mechanisms of hypothalamic-pituitary-gonadal axis in females and males and consequences of interruption of feedback mechanisms. GOAL: To describe the function components of the reproductive systems of male and females, the physiological basis for reproductive cyclicity in females and changes in the reproductive systems that occur at the puberty in males and females.
