While a woman is born with all the eggs that they will ever create, men create new sperm cells every 74 days. The exact time frame differs from person to person. The male reproductive cell is the sperm. The word sperm is derived from the Greek word “sperma” which means seed and is the smallest cell in the human body. It is a haploid, which means it contains 23 chromosomes, which is half the genetic material required to create a fetus.
While an egg always contains an X chromosome, the sperm can have either an X or Y chromosome. Therefore, the DNA carried by the sperm will determine the sex of the fetus. (XX for female or XY for male).

All About Sperm
Many different medical conditions and other factors contribute to fertility problems, and often there is a combination of causes. Overall, one-third of fertility problems are caused by male reproductive issues, one-third by female reproductive issues, and one-third by unknown factors. While 7% of the male population is affected by infertility, sadly, the subject of male infertility is rarely discussed openly, mainly due to social and cultural taboos.
