27.2 Reproductive anatomy of the human female ZOvaries ZContain follicles that nurture eggs ZProduce sex hormones ZOviducts ZConvey eggs to the uterus

Ovulation ZAn egg cell is released from a follicle at the surface of an ovary

Reproductive anatomy of the human male ZSemen ZSperm, which are expelled through the ducts during ejaculation ZGlandular secretions that carry, nourish, and protect the sperm ZTestes ZProduce sperm ZLocated outside abdominal cavity within the scrotum

Bladder (excretory system) Bulbourethral gland Prostate gland Epididymis Vas deferens Urethra

Androgens stimulate sperm production Z They also maintain homeostasis by a negative feedback mechanism that inhibits the secretion of FSH (follicle-stimulating hormone) and LH (luteinizing hormone)

Stimuli from other areas in the brain Hypothalamus FSH LH Testis Androgen production Sperm production Negative feedback Releasing hormone Anterior pituitary
