Male Genitalia Function Flashcards
penis
involved in sexual arousal, excretion of urine and transfer of sperm
foreskin
- unclear
- may protect the glans
- smegma can build up under the foreskin and develop foul smell/taste
cavernous bodies (corpora cavernosa)
- fill with blood during arousal
- account for most of the penile erectile ability
spongy body (corpus spongiosum)
spongiosum raises the visible ridge on the underside of the penis during sexual arousal
urethra & urethral opening
transport of urine and semen
corona and frenulum
corona and frenulum are usually the most erotically sensitive regions
PC (pubococcygeneous) muscle
- contraction during sex stiffens vaginal walls
- contractions stronger at orgasm
- prevents urinary/fecal leackage
- PC muscle control can allow men the ability to delay ejaculation
scrotum
- contains testicles
- maintains proper testicle temperature
- stimulation of the scrotum is sexually arousing to most men
testicles
- produce sperm
- secrete sex hormones
seminiferous tubules
production of sperm
sperm
fertilization of ovum (egg)
interstitial cells
secrete sex hormones
epididymis
site of sperm maturation and storage
vas deferens (vas)
transport and storage of mature sperm from the epididymis to the ejaculatory duct
ejaculatory duct
empties into urethra within the prostate
