Female pigs can recognize the sex of sperm and influence the sex of their offspring PhysOrg - May 21, 2014
Female pigs' reproductive systems recognize whether a sperm will produce a boy or a girl before it reaches and fertilizes the egg, and their oviduct (fallopian tubes) change in response. Scientists think this may be a way females unconsciously influence the sex of their offspring. Although in nature the ratio would normally be 50:50, this suggests females might be able to change the environment of the oviduct to favor one sex over the other, giving that sperm a better chance of winning the race to the egg.
