Why Does Vaginal pH Become More Acidic During Puberty? Explained by Science

Which change is a result of puberty and defends the vagina frominfection?a. The pH stabilizes between 7 and 8.b. A thin squamous epithelial liningdevelops.c. Vaginal pH becomes more acidic.d. Estrogen levels are low.a. The pH stabilizes between 7 and 8.b. A thin squamous epithelial liningdevelops.c. Vaginal pH becomes more

CAt puberty, the pH becomes more acidic (4 to 5) and the squamous epithelial lining thickens. These changes are maintained until menopause (cessation of menstruation), atwhich time the pH rises again to more alkaline levels and the epithelium thins out.Therefore protection from infection is greatest during the years when a woman is most likely to be sexually active. Estrogen does not play a role in infection protection

c. Vaginal pH becomes more acidic is the answer.

During puberty, the production of estrogen in the female body increases. This increased production of estrogen is responsible for changes in the female reproductive system, such as the development of the breasts, growth of pubic hair, and the start of menstruation.

One of the changes that occur in the female reproductive system as a result of puberty is a more acidic vaginal pH. The normal vaginal pH in prepubertal girls is around 7.0, which is close to neutral. However, during puberty, the growth of lactobacilli, a type of bacteria in the vagina, increases due to the higher levels of estrogen. These lactobacilli produce lactic acid, which lowers the pH of the vagina to around 3.8 to 4.5.

The acidic environment helps to protect the vagina from infection by preventing the growth of harmful bacteria and fungi. It also helps to maintain a healthy balance of microorganisms in the vagina, which is necessary for proper vaginal health.
