Is there a relationship between age at pregnancy and giving birth to a girl?

Patient's question:

No

Doctor's answer:

Hello, as you mentioned, it is generally not very relevant. The method of eating baking soda to increase the chances of having a boy may increase the alkalinity in the body, inhibit the activity of sperm with the X chromosome, and enhance the activity of the Y chromosome, thereby increasing the likelihood of it combining with the egg and raising the probability of having a boy.
