Document Summary
Sexual anatomy: male and female sex organs arise from the same structures and fulfill many of the same functions, gonads (ovaries/testes) produce germ cells (ova/sperm) and sex hormones. Fallopian tubes extend from top of the uterus: end of each oviduct surrounds an ovary. Involuntary reflect: may contain sperm pull-out method is not reliable, can spread stis. Hormones and the reproductive life cycle: males and females produce testosterone, estrogens, and progestogens, quantities differ, androgens: male sex hormones made by the testes, testosterone: most important. Estrogens and progestogens: female sex hormones made by the ovaries. 2: adrenal glands also produce sex hormones in both males and females. Sex chromosomes: 23rd pair of chromosomes: mothers contribute x; fathers contribute x or y. In puberty : reproductive system matures, secondary sex characteristics develop, bodies of males and females begin to appear more distinctive, changes are induced by testosterone in males and estrogen and progesterone in females.
