Sexual Positions for Gender Selecting

There are many arguments surrounding the topic of gender selecting. Some experts believe there are sexual positions and certain methods involving timing, positions and depth of penetration that can help a couple purposely conceive a boy or conceive a girl. Other experts believe that there’s no way to predict or pre-determine an embryo’s gender using such methods. However, there is scientific evidence that shows certain situations can yield gendered results.

Every woman’s egg carries an X chromosome (one of two chromosomes needed to make up a biological gender). Every man carries millions of sperm, some of which are female and contain X chromosome, and some of which are male and contain a Y chromosome. Whether a child is a male or female depends solely on the male’s sperm contents. Most gender selection methods focus on the characteristics of these chromosomes. For example, X chromosomes (girls) are slower and larger than Y chromosomes (boys). Also, X chromosomes are more resilient to acidity inside of the vagina and cervix, therefore allowing them to sort of “wait out” the Y chromosomes and increasing your chances of having a girl.  pH levels can be altered by things like diet and the presence of fertile cervical mucous. You can also dilute your acidity levels by douching after sex, however, this is not recommended if you are TTC.

Best Sexual Position for Conceiving a Boy

The most popular position for conceiving a boy is from behind, or doggy style. Male sperm do not live as long as female sperm, but they travel fast, rushing towards the uterus. The doggy style position allows for deep penetration and less traveling time to the egg, increasing the odds of conceiving a boy.

TIP: Women should ease up on the dairy and sodium, as male sperm prefer a more alkaline environment. Men should drink caffeine rather than alcohol to speed up the male sperm.

Best Sexual Position for Conceiving a Girl

Many experts say that since female sperm are resilient and last longer than male sperm, that sexual positions should include ones that penetrate shallowly. Spooning is a great example of a sexual position that has shallow penetration. Female sperm take their time traveling to the egg, allowing them to live up to 3-5 days longer than male sperm, which increases the odds of conceiving a girl.

TIP: Women should eat more dairy products and sweets, as female sperm love an acidic environment. Men should try not to drink too much caffeine or anything that will cause your male sperms to energize.
