stem cells in the ovaries which produce primary oocytes, each month one develops into a secondary one capable for fertilisation
what are the male reproductive hormones
hypo-GnRH gonadotrophins- FSH- spermatogonia LH- leydig cells testosterone
where is sperm produced

describe term travel and release
sperm created in testes
travels in epididymis
seminal vesicles and prostate make semen then travels along urethra
ejaculation
describe spermatogenesis
spermatogonium primary spermatocyte secondary spermatocyte spermatids mature sperm
what is the lifespan of a spermatoza
60-70 days
10-14 days in epididymis
factors affecting oogenesis or spermatogensis
problem with hormonal control-tumours, geentic
problem at site of production
