Semen pH

Semen pH is an indicator of acidity or alkalinity of the seminal fluid. Under normal conditions, semen is slightly alkaline with a pH ranging from 7.2-8.0 according to WHO guidelines.

Semen helps nourish and protect sperm. Having the optimum pH level in semen is important to keep sperm cells healthy and mobile, while the alkalinity helps to neutralize the acidic vaginal environment. If the semen pH is abnormal, either acidic or too alkaline, it can interfere with the sperm quality, causing subfertility or infertility.
