Can Alkaline Food Help Conceive A Boy and Acidic Food Conceive A Girl?

The pro side claims to change the internal acid-base environment of women. However, the pH value in human body is relatively constant and the change by eating alkaline foods is temporary, limited and insignificant. There is no scientific evidence of changing the pH value in human body through food intake.
 

In fact, the human body is ingenious and complex: from the digestive system to the excretion system and the respiratory system, the acid-base balance is precisely controlled; the intake of only alkaline drinks or alkaline foods cannot change the pH in the female reproductive tract. In the process of fertilization, sperms move through the uterus, pass through the cervix and finally reach the fallopian tube. The acid-base environment of these reproductive tracts varies, and the pH value is always in a certain range to ensure the normal physiological functions.
 

The normal vagina is in acidic environment, which can effectively inhibit the growth of harmful bacteria. The uterus has a neutral environment while the fallopian tube is in weak alkaline environment. Eggs are very sensitive to pH value during fertilization. The change in pH value, whether significantly or insignificantly, will affect the fertilization and even lead to infertility. Actually, a significant change in the pH value of female reproductive tract often indicates inflammation or pathology. For example, the imbalance of bacteria in vagina leads to a more acidic environment, which will inhibit the growth of probiotics secreting acid, while the vigorous growth of harmful bacteria can increase the chance of vaginitis. Another example is that in some patients of fallopian tube jam, the salpingal fluid is more alkaline than the normal. Therefore, it is better to spend more time to get fully prepared for a healthy baby by balancing diet, doing physical exercise, keeping in expansive mood and improving physical quality than to increase the chance of conceiving a baby boy by making the body alkaline thru diet.
