Is the vaginal environment better acidic or alkaline?

Patient's question:

No

Doctor's answer:

Under normal circumstances, the vaginal environment of a woman is an acidic environment,
while semen is an alkaline environment. Although there is no evidence, it is generally believed that an acidic environment is beneficial for having a daughter, while an alkaline environment is beneficial for having a son. Generally, consuming a large amount of fruits before giving birth is considered, but this is all a probabilistic event and cannot be considered scientific.
