Explanation:
Detailed explanation-1: -The production of sperm–otherwise known as spermatogenesis–generates more than 1, 000 sperm per second in normal males.
Detailed explanation-2: -A fertile male human ejaculates between 2 and 5 mililiters(ml) of semen (on average about a teaspoon). In each ml there are normally about 100 million sperm.
Detailed explanation-3: -For healthy men, testis weight (19 testes) averages 16.9 + or-1.2 gm and daily spermatozoal production was 4.25 times 10(6)9m (range = 1.4-6.3 times 10(6)/9m). Based on our total sample of 23 patients, 67% of the men 20-50 years old probably produce between 45 times 10(6) and 207 times 10(6) spermatozoa/day.
