The nervous system. Sex hormones masculine or feminize the brain and influence sex drive. Hypothalamus regulates timing of puberty; neural reflexes regulates events of sexual responses

Endocrine system. Gonadal hormones exert feedback effects on hypothalamic pituitary axis; a placental hormone promotes maternal hypermetaboilism. Gonadotropins (and GnRH) help sregulate function of gondas.

Cardiovascular system. Estrogen lowers blood cholesterol levels and promotes cardiovascular health in premenopausal women; pregnancy increases workload of the Cardiovascular system. Cardiovascular system transports needed substances to organs of reproductive system; local vasodilation involved in erection; blood transports sex hormones.

Lymphatic system/immunity; developing embryo/fetus escapes immune surveillance (not reject). Lymphatic vessels drain leaked tissue fluid; transport sex hormones; immune cells protect reproductive organs from disease; IgA is present in breast milk.

Respiratory systempregnancy impairs descent of the diaphragm, promotes dyspnea. Respiratory system provides oxygen; disposes of carbon dioxide; vital capacity and respiratory rate increase during pregnancy.

Digestive system digestive organs crowded by devolving fetus; heartburn, constipation common during pregnancy. Digestive system provides nutrients needed for health.

Urinary systemhypertrophy of the prostate gland inhibits urination; compression of the bladder during pregnancy leads to urinary frequency and urgency. Kidneys dispose of nitrogenous wastes and maintain acid-base balance of blood of mother and fetus; seamen discharge through the urethra of the male.

Integumentary systemandrogens activate oil glans which lubricates skin and hair; gonadal hormones stimulate characteristic fat distribution and appearance of pubic and axillary hair; estrogen increase skin hydration; enhances facial skin pigmentation during pregnancy. Skin protects all the organs enclosure; mammary gland secretions (milk) nourish the infant.

Skeletal systemandrogen masculinizes the skeleton and increase bone density; estrogen feminizes the skeleton and maintains bone mass in females. The bony pelvis encloses some reproductive organs; if narrow, the bony pelvis may hinder virginal delivery of an infant.

Muscular systemandrogens promote increase in muscle mass. Abdominal muscle active during childbirth; muscles of the pelvic floor support reproductive organs and aid erection of penis/clitoris
