Hmmm. No evidence that the effect transfers to humans though. From the same article;
“There is no evidence of such effects in humans, but there has not been any research on this possibility in humans. There is a potential for such effects in mammals,” explained Crean. “For example, there is a lot of foetal DNA in maternal blood during pregnancy, and this could potentially play a role in such effects. There is also evidence in mammals that seminal fluid affects offspring development, so semen from one male could potentially influence the development of eggs fertilized by another male (which is what we think is happening in flies).”
Crean added that due to ethical restraints it would be difficult to conduct a similar experiment on humans.
The key phrase here IMO is "could potentially"; I'd say the jury is out on this one. (Where is Udarnik when you need him?)
