Hey baby, you smell hot

A new study showed that men can smell when women are fertile, and rate those smells as "pleasant" and "sexy". From the New Scientist article:

"Singh and his colleague, Matthew Bronstad, gave a pair of previously unworn T-shirts to women volunteers.

Women slept in the first T-shirt during the fertile phase of their cycle - 13 to 15 days after their previous period. They slept in the other T-shirt during the infertile phase on days 21 to 22 of the cycle.

The women avoided contact with strong odours to avoid masking subtle scent changes. They washed with unscented toiletries, avoided sex and gave up spicy or aromatic foods, such as garlic. Two women had to drop out after indulging in pizzas and cigarettes.

When men sniffed the 21 pairs of T-shirts, 17 gave a resoundingly higher rating to the smells from the fertile phase. They had been told that one set of T-shirts came from women who were more attractive."
