When looking for the perfect man, women rely on their sense of smell, though many don’t realize they’re doing so. Although there’s still a great deal to be learned about why some women are attracted to men who smell a certain way, research indicates that it could have something to do with an age-old, instinctive desire to find a mate that’s in good health.
Researchers have invested many hours into observing mice and trying to determine why the females were drawn to a particular male. The scientists quickly realized the prized male was the one who had a very strong immune system. This corresponded nicely with research gathered during the course of another experiment, which indicated that the female mice appeared to seek out males that had an immune system which varied slightly from the females and which should have resulted in baby mice that were healthier and stronger than their parents.
Researchers also discovered that the peptides the mice used to help choose the perfect mate were secreted in the male’s urine, and each of these peptides was unique to the mouse they came from, acting as a kind of fingerprint.
It turns out that the females are able to smell the peptides, and keep a record of the scent and her prospective mate’s health by using the vomeronasal organ within her nose.
Researcher, Frank Zufallexplainedhow important peptides are in healthy reproduction among mice. “Exposure, during a critical period, to urine odor from another male, will prevent embryo implantation, leading to loss of pregnancy, while exposure to the familiar odor will not.
We can trick this odor memory and the outcome of the pregnancy-block test by adding peptides to urine. In other words, we can switch an unfamiliar urine odor to a familiar one (and vice versa) by spiking the urine with only a few peptides.
“Zufall feels that the scent of the male’s peptides doesn’t just impact the reproductive life of mice. “We believe that detection of [immune system] peptides via the nose may be of general significance for social behaviors in all vertebrates.”
There’s no denying that the way a human man smells plays a huge role in whether or not a woman will agree to go out on date with him, and there’s also evidence that men secrete a different kind of smell when they’re interested in sex. It stands to reason that men who use peptide supplements to boost their immune system might also improve their love life. Specifically, men in search of love would need additive free peptides to boost thymus activity.
Is it possible that peptides could be the solution for men who want to find lasting love? Scientists are still doing research to learn more about how peptides impact sexual attraction, but with many other benefits of peptide supplements already well known, it couldn’t hurt to try.
