Some people find out their baby’s sex through noninvasive prenatal testing (NIPT). This is a blood test that can detect Down syndrome and a few other chromosomal conditions at 10 weeks of pregnancy or later. It also looks for pieces of the male sex chromosome in the expectant mother’s blood to see if she’s carrying a boy or a girl.
Others find out their baby’s sex from a genetic test like CVS or amniocentesis. These tests are usually used to determine whether a baby has a genetic disorder or a chromosomal abnormality like Down syndrome but may carry a slight risk of miscarriage. CVS is typically done between 10 and 13 weeks and amniocentesis between 16 and 20 weeks.
How to Have a Baby Girl or Boy: Other Factors that Decide Your Baby’s Gender
1. The pH of the woman’s vaginal tract can be important.
For those who want to know how to have a baby girl, a more acidic environment favors the conception of a girl. This is because the acidic environment will kill the weaker Y-sperms first. This leaves a greater quantity of X-sperms available to fertilize the egg.
On the other hand, a more alkaline environment favors boys. The Shettles method recommends a douche of water and vinegar (acidic) immediately before intercourse to positively influence the conception of a girl; a douche of water and baking soda (alkaline) will help for a boy.
2. Position of intercourse and depth of penetration are also important.
The closer to the entrance of the vagina, the more acidic a woman’s tract is. Also, deep penetration places the sperm closer to the egg, and gives those aggressive Y-sperms a head start. So, shallow penetration favors the conception of girls and deeper favors the conception of boys. Scientists recommend the missionary position for a girl, and rear-entry (dog-style) for a boy.
3. Women’s orgasms can also be important.
Once again, this factor involves pH balance. When a woman has an orgasm, the body releases a substance that makes the environment more alkaline, favoring boys. Scientists recommend no orgasms when trying for girls!
