Low Tech Gender Selection

It’s important to remember that with each pregnancy, a couple has a 50 percent chance of having either a boy or girl. All semen contains a 50:50 ratio of X-bearing sperm to Y-bearing sperm.

Timed intercourse, sex selection kits and special diets may seem to influence gender, but the research does not support anecdotal evidence.

For example, Shettles’s Method claims an 80 percent success rate for boy conceptions and about 74 percent success rate for girl conceptions. However, the American Journal of Obstetrics and Gynecology published a study that failed to confirm Shettles’s theory on intercourse at ovulation would result in more male offspring. The New England Journal of Medicine reported similar findings.

Elizabeth Whelan claims the Whelan Method is 68 percent effective for conceiving a boy and 56 percent effective for conceiving a girl, but fertility experts disagree.

You always have a 50 percent chance of conceiving a baby of the sex you want. The only sure way to choose the sex of your baby is via a high-tech method: preimplantation genetic screening (PGS), which is 99.9 percent effective.
