Internal structures of the erect penis
-The penis and the clitoris are developmentally similar
-corpous cavernosum – surrounded by the tunica albuginea which further contributes to erectile
properties of the shaft
-2 muscles associated with the penis, the ischiocavernosus and bulbospongiosus muscles, assist
with erection and ejaculation
-of the end most portion of the glans, tube that allows for elimination and excretion of sperm and
urine – urethral meatus
Medical problem associated with the penis
-”it is” = inflammation
-HPV can cause cancer in the penis
The male reproductive tract
-scrotum – located behind the penis and contains the testicles
-in adult males, lots of sweat glands around the scrotum
-shape and size of scrotum changes around puberty
-the production of sperm needs to take place at a cooler temperature (4-7 degrees cooler than the
-sweat glands in scrotum region help to maintain temperature
The scrotum and its contents
-first place where sperm start to leave once mature – epididymis
-spermatic cord – often suggested to be the lifeline of the testis
-connects the testis to the abdominal cavity and provides nutrition to the testis through the
exposure of blood
-has a sheet-like covering of connective tissue that surrounds it
-if connective tissue rips there could be a lot of pain
-contains lots of arteries, nerves and veins
-cremaster muscle – striated muscle β—Š light and dark bands (striations)
-important for movement of the testicles
-pulls testicles closer to body if exposed to cold harsh environment fore example
-vas deferens – runs throughout male reproductive system
-carry mature sperm away from the epididymis and urine away from the bladder
-flowing blood also provides temperature regulation – flowing blood produces heat
Internal structure of the testis and epididymis
-site of sperm production – seminiferous tubule
-sertoli and leydig cells important for hormone production
-sertoli cells start to produce hormones which go up to the brain of the fetus and start
differentiating the male brain from the female brain
-have impact and start cell differentiation
-leydig cells produce similar hormones as sertoli
-contribute to sex differentiation
