DRUGS AND MALE FERTILITY - Orange County Rehab - Alcohol & Drug Addiction Treatment

By Lois Rogers. From eating the right foods to adopting certain positions, there is much conventional wisdom about what couples should do to boost their chances of having a baby. One popular idea is that men should abstain from sex before trying to conceive to build up their sperm count and improve their potency. Crucially, it is the second attempt that is thought to count. The study involved 73 couples who were all undergoing intrauterine insemination IUI , a fertility treatment where sperm is placed directly into the womb. When the men, who were classed as sub-fertile, produced two sperm samples within the hour and the second sample was the one used in the treatment, it resulted in a pregnancy rate of 20 per cent — more than three times the 6 per cent success rate expected with this technique.

We are drawn to features of the human body that tell us our partner is healthy and will provide us a fighting opportunity to carry on our genetic lineage. But a new article appearing in the February issue of Current Directions in Psychological Science suggests that the human male has evolved mechanisms to pass on his genes during post-copulation as well, a phenomenon dubbed "sperm competition. In their article, Todd Shackelford and Aaron Getz at Florida Atlantic University describe sperm competition as "the inevitable consequence of males competing for fertilizations.
