A semen-like smell "down there" is often normal, caused by vaginal pH changes from sweat, hormones, diet, or recent sexual activity (semen is alkaline, changing pH). However, if accompanied by unusual discharge, itching, or persistent odor, it could signal an infection like bacterial vaginosis (BV) or trichomoniasis, requiring a doctor's visit for treatment with antibiotics or antifungals. Keeping the area clean, wearing breathable cotton underwear, and staying hydrated can help manage temporary changes.
Semen is naturally alkaline, while the vagina is slightly acidic. When semen mixes with vaginal fluids, it can temporarily raise the pH level, creating an environment that is more conducive to the growth of certain bacteria. This change in pH can sometimes lead to an increase in vaginal odor.
The smell is sometimes described as insipid – a bit like sperm. If you have symptoms that are not normal, such as a very different or unpleasant-smelling discharge, you should see a doctor. The symptoms may be caused by an infection in the vagina, fungal infection or bacterial vaginosis.

Normal, Healthy Vaginal Odors

In most cases, vaginal scents are very normal, and odor alone is not a symptom of a problem. The vagina and the area around it (groin skin, vulvar, etc.) contain healthy bacteria that are a part of our microbiome and include sweat glands. These can produce an odor that varies for each person.

This distinct smell is due to an imbalance of vaginal bacteria, leading to an overgrowth of odor-causing bacteria.
