Are you the mom of three boys and you are just dying to get that baby girl you’ve always dreamed of? Or, maybe you have always wanted your first born to be a boy. Well, according to modern science, some popular research and many people who swear by these methods, there are several things you can try to increase your chances of conceiving the gender you desire.
How a Baby’s Gender Is Determined
Before getting into the different methods of gender selection, let’s talk a little bit about how a baby’s gender is determined. If you are a female you carry two X chromosomes (XX). If you are a male, you carry an X chromosome and a Y chromosome (XY). When a man and a woman conceive a child, they each pass on one of their chromosomes. The woman passes on an X chromosome (which is all she has to offer) and the man can pass on an X chromosome or a Y chromosome. If he passes on an X chromosome, the baby will be a girl. If the man passes on a Y chromosome, the baby will be a boy. So, basically it is the dad’s DNA that determines what sex the baby will be.
Girl = XX
Boy = XY
The mom passes on an X chromosome and the dad can pass on either an X chromosome or a Y chromosome, determining the baby’s gender.
Now that you understand the basics of gender DNA, let’s talk about some ways that can increase your chances of conceiving one gender over another.
The Shettles Method
Probably the most popular method of gender selection is that determined by Dr. Landrum B. Shettles in the 1960s and made popular by his book How To Choose The Sex of Your Baby. The basis for this method is the premise that sperm carrying the female (X) chromosome and male (Y) chromosome have different characteristics and you can encourage one or the other to reach the egg and fertilize it first through the timing of intercourse and how you do it.
Characteristics of Female Versus Male Sperm
- Female sperm (containing X chromosome) are more resilient (live longer), but are slower. They thrive in an acidic environment where Y sperm struggle.
- Male sperm (containing the Y chromosome) are faster, but die sooner. They thrive in an alkaline environment.
To Conceive a Girl Using the Shettles Method:
- Have sex 2-3 days before ovulation, so that the long-living female sperm will remain inside the woman waiting for the egg while the male sperm die off.
- Refrain from having sex in the couple of days leading up to ovulation and for two days after to avoid the speedy male sperm beating the female sperm to the egg.
- Have intercourse in a shallow position that will deposit the sperm furthest from the cervix, like the “missionary position.” This gives the advantage to the female sperm because they live longer and can travel longer distances and the cervical fluid closer to the entrance is more acidic, thus favoring the female sperm.
- The female should avoid having an orgasm as it can make the internal environment more alkaline, thus favoring male sperm (fun times, huh?).
To Conceive a Boy Using the Shettles Method:
- Have sex at the time of ovulation and just before so that the speedier male sperm have a chance to reach the egg first.
- Have intercourse in a deep position that will deposit sperm closest to the cervix, like with the man entering from behind. The cervical fluid closest to the cervix is more alkaline, favoring male sperm, and the short-lived male sperm have less distance to travel.
- The female should have an orgasm as this decreases the acidity of the woman’s i
