Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Males are born with all the sperm cells that they will ever have?

A	True
B	False
C	Either A or B
D	None of the above

Explanation:

Detailed explanation-1: -Spermatogenesis. Men aren’t born with ready-made sperm cells-they have to be made later, from puberty onwards. (Interestingly, when females are born they already have all their quota of eggs.) Spermatozoa are made in vessels, within the testicles, called seminiferous tubules.

Detailed explanation-2: -Sperm cells are male reproductive cells that originate in the testicles. Sperm cells swim to and fertilize a female reproductive cell called an oocyte, or egg. Two key factors that can affect male fertility are sperm count and sperm motility. Those experiencing fertility issues may benefit from a semen analysis.

Detailed explanation-3: -Each sperm cell contains half the father’s DNA. But it’s not identical from sperm to sperm because each man is a mixture of the genetic material from his parents, and each time a slightly different assortment of that full DNA set gets divided to go into a sperm.
