Normal Human Reproductive Male (between 20 to 50 years)
Spermatozoa Number/Time
produced / day (two testes) 45 to 207 million
compare adult human red blood cell production / day 250,000 million
produced / second each day (approx) 2,000
stored (epididymal reserves) up to per epididymis 182 million
stored extragonadal 440 million
extragonadal - ductuli deferentia and caudae epididymides per ejaculation 225 million
spermatozoa / gram testicular parenchyma / day (all animals approx) 23 million
Spermatozoa Transit Times
through the caput 0.72 day
through the corpus 0.71 days
through the cauda epididymidis 1.76 days
