Question: is cervical mucus acidic or alkaline?
Answer: PH Levels of Cervical Mucus Sperm perform best in a pH of 7.0 to 8.5 - neutral to slightly basic. However, normal pH for the vagina is between 3.5 and 4.0 - actually rather acidic. Much as the consistency of cervical mucus changes during ovulation, its pH also increases, becoming more alkaline.
