Number of millions of Spermatozoa available in male but only one sperm fertilize female egg, only one.

It takes just one sperm to fertilize a woman’s egg. Keep in mind, though, for each sperm that reaches the egg, there are millions that don’t.On average, each time men ejaculate they release nearly 100 million sperm. Why are so many sperm released if it takes only one to make a baby? To meet the waiting egg, semen must travel from the vagina to the fallopian tubes, a tough journey that few sperm survive. Experts believe this process may be nature’s way of allowing only the healthiest sperm to fertilize the egg, to provide the best chances of having a healthy baby.
