Document Summary
6 weeks: male and female embryos contain common gonads, gonads turn into testes or the ovaries, primitive reproductive tracts. Y chromosome causes the testes to develop. Testicular cells produce mullerian inhibiting hormone (mih) causing mullerian duct to regress. Mullerian duct develops into: the fallopian tubes, uterus, cervix, part of the vagina, male. No testosterone causes wolffian duct to regress and female external genitalia to develop. Surge of testosterone stimulates wolffian duct to develop into: epididymis, vas deferens, seminal vesicles, urethra. Presence of testosterone causes external genitalia to develop. List the functions of each of the male reproductive organs: function of male reproductive system, produce the sex steroid testosterone, to produce sperm and deliver it to the female vagina, external genitalia consists, penis cavernosum, scrotum. Erectile tissue corpus spongiosum and corpus: sperm and testosterone are produced, consists of 1000 coiled seminiferous tubules, seminiferous tubules, site of spermatogenesis, contains sertoli cells. Secrete fluid that pushes the immature sperm to the epididymis.
