Withdrawal also known as 'pulling out' is when the man removes his penis from the woman's vagina before ejaculation. This prevents the semen from entering the woman's body. However, even if the penis is withdrawn before ejaculation, pre-ejaculate fluid may contain sperm cells that can cause pregnancy and it may also contain organisms that cause sexually transmitted infections STIs , including HIV. Withdrawal is not recommended as a main method of contraception. It is dependent on the male partner, it requires great self-control, self-awareness and motivation, it may affect sexual pleasure, and it provides no protection against STIs. Couples are advised to use withdrawal only if both partners are prepared to deal with the consequences of the woman becoming pregnant.

The good news, there are some very tangible lifestyle changes that men can make to improve their sperm health and overall fertility. It is generally known that most men produce millions of new sperm every day. You also might not realize that when sperm are initially formed within the testicles, they lack the ability to swim forward or fertilize an egg until they make their way through the reproductive tract. Sperm are living cells within the male body and are subject to whatever conditions the rest of the body is exposed to throughout their development cycle. Extreme temperatures, smoking, drug use, and poor diet can all impact the quality of sperm.

Sperm in the first fraction of ejaculate are more numerous, move more and present better quality DNA than those lagging behind. This is the conclusion of a study led by the Ginemed fertility clinic, which confirms that while the objective of the first fraction is to fertilize the egg, the second phase is so that no sperm from any other male has a chance to fertilize it. A study led by the Ginemed Assisted Human Reproduction Clinic analyses the advantages of using fractions of ejaculate separately in in-vitro fertilization as a way to improve the sample of the semen. The researchers' hypothesis was that, comparing the different fractions of semen in an ejaculation, the first would contain sperm with better seminal parameters and could be used as an effective method for selecting sperm prior to fertilization. The first objective of ejaculate would be to fertilize the egg and the second so that no other male has the opportunity to fertilize it.
