How can I smell like a man

Can you smell a woman's fertile days?

When we cuddle up to our partner in bed in the evening, we prefer to do so if he also smells good. We don't mean perfume or aftershave, but the very own body odor that each of us has. Allegedly, the smell of another person should even be decisive when looking for a partner in order to achieve the best possible “genetic match”. Quasi: Always follow your nose when choosing a partner!

When it comes to having children, this evolutionary bag of tricks goes a step further. Because supposedly men can "sniff" a woman's fertile days and then find her even more attractive! But is that really true?

Changed body odor thanks to estrogens

Swiss researchers say: yes! Estrogens, the female sex hormones, are “to blame” for this. They are released more strongly around the fertile days than on other days of the cycle and stimulate ovulation. The changed hormone level is then reflected in the woman's body odor.

A study at the University of Bern with a total of 28 women and 57 men proved that women smell more attractive on their fertile days. The test subjects had to follow a very strict protocol: They were not allowed to use hormonal contraception, wash themselves with perfumed shower gel or sleep in bed with others. In addition, the women had to stick cotton pads in their armpits, which took on their smell and were "presented" to the men. Her cycle status was determined by taking a blood sample.

The result: the women who were about to ovulate tended to smell more attractive to the men. The higher the women's estrogen level in the blood, the better the male study participants rated the odor sample. There are purely evolutionary reasons for this: the reproductive instinct is still firmly anchored in most of us. The attractive body odor makes men aware that a woman is fertile and ready to reproduce.

Incidentally, the study also showed that the genetic factor is not decisive for the judgment of men. It is always said that you choose your partner by smell because he is supposed to tell us something about genetics and the state of health - sort of whether someone is a suitable reproductive partner for us. The result of the study showed, however, that men did not judge the attractiveness of women or their smell according to this, but purely according to the hormone status or cycle status. The typical body odor does not play a major role when choosing a partner - but it does play a role when it comes to "using" ovulation and passing on your own genes. In short: ovulation beats genetics!

Artificial hormones and body odor

But why weren't women actually allowed to use hormonal contraception? It is believed that the pill and other hormonal contraceptives can adulterate the woman's own odor. This is understandable because most pills deliver an artificial form of the hormone progesterone, which permanently prevents ovulation. It is the hormone of the second half of the cycle after ovulation. At the same time, the estrogen level remains permanently low. Too much progesterone, too little estrogens: In the study, too, this combination was not particularly irritable for the male test subjects.

But you have probably also heard of the theory that women who take the pill often choose the “wrong partner” for themselves - and suddenly cannot smell them anymore after they have stopped. Studies have found a slight association, but the evidence is too thin to make a definitive judgment. So don't worry: your relationship isn't doomed just because you're using birth control without artificial hormones!

What about the period?

In fact, previous studies have shown that a woman's body odor is most intense during menstruation. Men who are particularly sensitive to smell can even perceive this smell. But this is more the exception than the rule. And of course this body odor has nothing to do with your actual hygiene! It is simply genetically determined and shows that you are currently not fertile or only fertile to a limited extent.

It's interesting what our hormones do in the body! But if you don't want to rely exclusively on your partner's nose, femSense® will help you narrow down your fertile days. The sensor in the femSense patch uses another body indicator to determine your ovulation: your temperature. So you know for sure where you are in the cycle - even before your partner can “sniff” it.
