Study Notes
Secondary Sexual Characteristics in Males
- Development of increased muscle mass and strength.
- Growth of facial and body hair, including chest, abdomen, and back.
- Deepening of the voice due to enlargement of the larynx.
- Enlargement of the testes and penis.
- Increased bone density and growth spurts.
Maturation of Ova and Formation of Sperm
- Follicle-stimulating hormone (FSH) plays a crucial role in stimulating the maturation of ova in the ovaries.
- Luteinizing hormone (LH) triggers the production of testosterone, which is essential for sperm formation in the testes.
- Both hormones are produced by the pituitary gland.
Beginning of the Reproductive Period in Humans
- Puberty marks the transition into reproductive capability, typically beginning between ages 10 to 14 for males and 9 to 13 for females.
- Initial physical and hormonal changes initiate the formation of secondary sexual characteristics.
Secretions of Testes and Ovaries
- Testes secrete testosterone, which regulates the development of secondary sexual characteristics and sperm production.
- Ovaries produce estrogen and progesterone, which regulate the menstrual cycle, ovulation, and the development of female secondary sexual characteristics.
Initiation of Changes at Puberty
- The hypothalamus releases gonadotropin-releasing hormone (GnRH), signaling the pituitary gland to release FSH and LH.
- Increased levels of sex hormones trigger physiological and anatomical changes associated with puberty.
