One of the more recent trends among parents-to-be is the so-called gender reveal, a party complete with pink or blue cake to answer the burning question, "Is it a boy or girl?" After all, it's presumed that there's a 50-50 chance you'd have one or the other. In a new article published in Current Biology, Michigan Medicine researchers studying the sex chromosomes have discovered genes that, at least in mice, skew that assumed ratio to favor one sex and that could have major implications for male infertility.
