Having sex every day improves sperm quality and increases the chances of pregnancy, reveals an Australian study. The research, carried out by David Greening of the Sydney IVF in vitro fertilization center, was presented at the conference of the European Society for Human Reproduction and Embryology in Amsterdam (Netherlands).
According to Greening, eight out of ten men with fertility problems who participated in the study showed a 12% reduction in DNA damage in their sperm after a week of sexual activity. In addition, the sperm also became more active after seven days, experiencing a small increase in motility. The researcher supports the theory that the longer the sperm spends stored in the testes, the more likely it is to accumulate DNA damage , attacked by free radicals.
As a conclusion to her study, Greening recommends that if couples are trying to conceive naturally, sexual intercourse every one or two days could ensure that sperm remain as healthy as possible. Of course, this assiduity is only recommended immediately before and while the woman is ovulating, since having sex daily for more than two weeks could perhaps reduce the volume of sperm too much, adds the expert.
