Doctors investigating a theory that contemporary orgasms succor fertility found that women who experienced pleasurable sex retained more active sperm from their partners than those that did not. The best way to get pregnant is to have a contemporary orgasm with your partner, scientists have ascertained.
Dr Cathy, from the School of Psychology at Ohio University, studied 65 women with an average age of 32. The women were asked to go to a clinic within a few hours after their sexual encounter for a post-coital test to measure how much sperm had been viable in the cervical mucus.They were also asked about whether their sexual encounter had been satisfying, and whether and when they had achieved orgasm.
Dr Cathy found that approximately half the women who experienced disappointing sex retained no sperm at all, compared with only one in twelve women who had enjoyed a satisfying sexual encounter. There are two preeminent hypothesis based on the findings.
The "in-suck" surmise argues that contraction during orgasm draws in the sperm after ejaculation. Arousal has also been shown to reduce acidity inside the vagina. According to this theory an acidic vagina lessens the chances of sperm surviving to the reproductive tract.
Dr Cathy added: "The number of sperm in the cervical mucus is an important predictor of future fertility, then the findings outlined may have cardinal implications for infertile couples.
