Interesting Facts About Sperm

After reaching g puberty, a male produces millions of sperm cells every day. Sperms are tiny bodies (about 0.05 millimeters long) produced and stored in the testes of male reproductive system. They consist mainly of genetic material and a long tail that helps them move through the female’s reproductive tract to reach an egg cell. Each ejaculation can contain up to 500 million sperm. But those new sperm cells aren’t made overnight. A complete cycle of sperm production and maturation (spermatogenesis) takes approximately 64 days on average. Dr Nisha Pansare, Fertility Consultant, Nova IVF Fertility, Pune, shares some more interesting facts about sperm.
