Story summary

A study published in Evolution and Human Behavior finds that modern women may not chemically signal fertility through vulvar odor.
Researchers found no evidence that men could detect a woman's fertile phase based on scent.
The study involved 28 women aged 20–30 who followed strict dietary protocols and underwent hormone testing.
Future research may explore these cues in more natural settings or examine the vaginal microbiome's role in scent production.
