A study published in the Journal of Proteome Research found that sperm can’t fertilize an egg immediately after entering the female reproductive tract. No, sperm are fickle little guys. An activation process scientists call “capacitation” has to take place in them. Basically, the cells in the sperm have to be “turned on” for them to do their deed. So, not only do you and your man have to be in the mood to make babies, but so do his male reproductive cells. Researchers are working on figuring out what gets sperm in the mood.
