We know that the constructs of sex and gender are ever-evolving. For the sake of this article, when we refer to conceiving a girl, we are speaking strictly about chromosomes — specifically a baby with two X chromosomes. Chromosomes determine the biological sex of a person. Females have two X chromosomes and males have one X and one Y chromosome. During conception, sperm will contribute either an X or a Y chromosome.
When the sperm passes an X chromosome girl sperm , the couple conceives a girl. And when the sperm passes a Y chromosome boy sperm , the couple conceives a boy. For generations, scientists have tried to determine if there is a link between maternal diet and natural sex selection.
And while there are a handful of studies that seem to have come to similar conclusions, many of these studies were performed on other mammals such as cows or rats. Therefore, more research on human subjects is needed before we can say for certain if there is a link between maternal diet and conceiving a specific sex. According to a study , women who consumed a strict diet high in magnesium and calcium along with timing intercourse had a greater chance of conceiving a girl.
A study from looked at the diet of women and found that mothers who consumed higher calories tended to have boys. Researchers believed that there was potentially a link between higher levels of glucose in the blood, which was favorable to male sperm. To ensure healthy blood sugar levels , avoid foods high in added sugar and be sure to consume plenty of fiber, protein, and healthy fats. But, we do know that healthy sperm helps increase the likelihood of conception, and diet can help boost healthy sperm count.
This option, however, is expensive, and even illegal in some countries. Get the BabyCentre app. Brazil Canada Germany India. Connect with us. This Internet site provides information of a general nature and is designed for educational purposes only.

Myth 3: To increase likelihood for a boy, women should increase potassium in their diet. One study indicated that there was an association between potassium and having a male baby, but offered only minimal proof that this was a reliable method. Myth 4: Women who use an expectorant like cough syrup can increase the fluidity of their cervical mucus to lubricate the way for Y-chromosome sperm.
Myth 5: Changing the pH factor in the vagina can help. If you make the vagina more acidic by using a vinegar douche, it favors a girl. If you make it more alkaline by using a baking soda and water douche, it favors a boy. Currently, the only way to guarantee sex is a technique called preimplantation genetic diagnosis PGD , where a single sperm is implanted in the egg in a type of in vitro fertilization called ICSI intracytoplasmic sperm injection.
A cell of the developing embryo is tested to determine sex prior to placement in the uterus of the mother.
