Gender selection by diet?

Question

Has anyone else heard of this? My first child was a boy and A girl at work was telling me that there are certain foods that you can eat to change the pH balance of your body to be welcoming to female sperm? I looked it up and found a lot of websites suggesting this diet

Answer

I think they are called the HE and LE diets? However I don't think there is much scientific evidence backing it. Now I did just read a book and it suggests timing before ovulation is the way to go, and it did mention numerous studies involving both animals and humans. In a nutshell to attempt to conceive a female you'd want to have intercourse once, 2 days prior to ovulation. For a male you have sex closer to ovulation and multiple times. Their research points to the way X and Y sperm encapsulate.
