The Weird Way Your Menstrual Cycle Affects Your Guy’s Hormones

We all know how that moodiness around our periods can drive our partners just a bit insane. But your menstrual cycle actually has a biological effect on your partner, too. Yup, per a study, your cycle could boost his testosterone levels. Ah, hormones…

The study

Animal studies found that olfactory cues of ovulation (when a biological female releases an egg, awaiting fertilisation by sperm) affected male testosterone levels. Studies conducted by researchers from Florida State University found that the same thing happens to male humans.

In the studies, women wore t-shirts during different phases of their menstrual cycles. The men in the studies smelled one of the t-shirts worn by a female or unworn t-shirts. Saliva samples were collected before and after smelling the t-shirts s and measured for testosterone levels.

Men who smelled the t-shirts of ovulating women had higher levels of testosterone than men who smelled a t-shirt worn when the women were not ovulating or a control t-shirt. The scent of t-shirts worn when the women were ovulating was rated as the most pleasing. These olfactory findings brighten the signal that when you’re ovulating, it’s prime time for fun in the sheets.

But the needle can swing both ways. In another study, researchers measured levels of hormones in heterosexual partners throughout the woman’s menstrual cycle. What they found was surprising: during ovulation, when levels of estradiol are elevated, both partners felt more negatively toward each other than at other times of the cycle. Clearly, your menstrual cycle plays a bigger part in the relationship than you’d think.

When his testosterone starts to wane…

With age, men’s testosterone levels do naturally start to decrease. Instead of shoving your nightie under his nose once a month, you could also steer him in the direction of these healthy foods, proven to up his levels: eggs, peanuts, yoghurt, oysters, garlic, oats, avocado, salmon (or other oily fish), fresh fruit and veg, pine nuts, brown rice and liver.
