If you're hoping for a specific baby gender, you may be interested in this new UK based research. According to Reuters, your baby's gender might have more to do with the father's genes, than the mother's. Reuters Health notes the following: A UK researcher, Corry Gellatly, a scientist at Newcastle University, has a new theory about how the human race keeps "A fairly even balance of males and females, despite massive deaths of young males in war and selective abortion of female fetuses in certain parts of the world." Gellatly thinks there's "A gene that determines whether a man will father more sons, more daughters, or equal numbers of each." Some of the research shows that... When females are in short supply, they're more likely to find a partner, which means they're more likely to pass the gene for fathering daughters on to their offspring. When males are in short supply, they of course have a better chance of finding a partner, and thus also passing along the gene for having sons. Oddly, throughout history, at the end of each major world war, male births have jumped higher than female births. This is just one example of the population righting itself. Some theories are that "Returning soldiers have extra-frequent sex with their partners, which could lead to fertilization earlier in the menstrual cycle, possibly making male births more likely or that larger males are more likely to survive wars and more likely to father boys." Gellatly explanation is that men carry a gene that controls their ratio of X to Y sperm which is directly related to their likelihood of having a boy or girl baby. Women have this too, but they don't express the gene. It's an interesting article, and well worth a read if you're interested in gender odds.
