Progesterone
Progesterone is a hormone produced by the ovaries that helps regulate the menstrual cycle. Progesterone levels spike during ovulation and drop again just before menstruation begins. This fluctuation in hormone levels can cause changes in vaginal odor. Some women report that their vaginal odor becomes more pungent during ovulation, while others say it becomes sweeter or muskier.
Another way that progesterone can affect vaginal odor is by altering the pH balance of the vagina. During pregnancy, progesterone levels increase and can cause the vagina’s pH level to become more alkaline. This change in pH level can make the vagina more susceptible to infections, leading to changes in vaginal odor.
Vaginal odor is not necessarily an indicator of good or bad hygiene. The vagina is home to millions of beneficial bacteria that help to keep it healthy. These bacteria produce enzymes that break down sweat and other fluids into compounds with a distinctive and often strong smell. This is perfectly normal and nothing to be concerned about. However, if a woman notices a sudden change in her vaginal odor that lasts more than a few days, it is best to see a doctor immediately.
