How Do You Improve Your Chances of Conceiving a Boy?

Special diets, certain intercourse positions, careful timing of intercourse and fast intercourse are all methods some couples have used to naturally increase the odds of conceiving a boy, according to Babble. Experts advise men to wear boxers instead of briefs and women to consume cough syrup prior to intercourse. Most doctors, however, stress that gender-testing embryos prior to in vitro fertilization is the only way to ensure conception of a boy.

Some experts claim that women should avoid acidic foods to increase the chances of conceiving a boy, since fragile, Y-chromosome sperm survive longer in more alkaline environments, notes Babble. Additionally, such experts advise that women eat caloric foods throughout the day and consume cough syrup to thin the cervical mucous, which assists Y-chromosome sperm in swimming faster. Men are advised to consume caffeine immediately before intercourse to further speed along Y-chromosome sperm.

One expert, Dr. Landrum Shettles, author of "How to Choose the Sex of Your Baby," believes that sexual positions that allow for deeper penetration favors the conception of boys due to the acidity of a woman's vagina near its entrance, as reported by Babble. Dr. Shettles also advocates that abstaining from intercourse until after ovulation increases the chances of conceiving a boy, because Y-chromosome sperm is faster than X-chromosone sperm and have a better chance of reaching the egg before it disintegrates.

Some couples claim to have successfully conceived a boy by having intercourse according to a lunar calendar and by having quick intercourse, notes Babble, although no science backs the use of these methods.
