Prolactin
The female body is constantly undergoing hormonal changes, which can affect a woman’s vaginal odor. In particular, the prolactin can have an impact on the way a woman’s vagina smells. Prolactin is a hormone that is produced by the pituitary gland. It is best known for promoting lactation but also plays a role in a woman’s reproductive cycle. Prolactin levels are highest during pregnancy and breastfeeding, but they also increase during times of stress.
While various factors influence vaginal odor, the most important factor in determining vaginal odor is the balance of bacteria in the vagina. These bacteria produce acids that keep the vagina clean and free of infection. The pH level determines the level of acidity in the vagina. This acidic environment keeps harmful bacteria from growing out of control.
Conversely, when the pH level becomes too high or too low, it can lead to an overgrowth of bacteria, resulting in an unpleasant smell. It is important to note that not all women will experience this side effect from high levels of prolactin. Some women may find that their vaginal odor improves when their prolactin levels are high.
