A pheromone is a secreted or excreted chemical factor that triggers a social response in members of the same species. Pheromones are chemicals capable of acting outside the body of the secreting individual to impact the behavior of the receiving individual. There are alarm pheromones, food trail pheromones, sex pheromones, and many others that affect behavior or physiology.

Have you ever met someone and instantly disliked them? Or felt unreasonably attracted to them? Have you also heard that when a women live together in one house, eventually their menstrual cycles tend to be the same?

What causes that? Yes, pheromones.
Humans have pheromones too, but we don’t act on it the same way animals do. Partly this is because of humans being hygienic. We wash away our sweat and flush away our excrements, the exact things containing our personal pheromones.

Many studies have been done to determine whether human pheromones exist, and like with so many different kinds of studies, there are evidence for both sides. Some studies show that human pheromones exist, others show they don’t. I am a believer that they do exist.

Researchers in the University of Chicago claimed that they managed to link the synchronization of women’s menstrual cycles to unconscious odor cues. The head researcher was called Martha McClintock, hence the coined term the McClintock effect. When exposing a group of women to a whiff of sweat from other women, their menstrual cycles either accelerated or slowed down, depending on when during the menstrual cycle the sweat was collected – before, during or after ovulation. The scientists said that the pheromone collected before ovulation shortened the ovarian cycle, while the pheromone collected during ovulation lengthened it. Even so, recent analyses of McClintock’s study and methodology have questioned its validity.

My uterus had been removed just before I turned 25. When our younger daughter started menstruating, I noticed that my nipples hurt about one week after that. At first I did not make the connection, until I realized that my cycle must be running parallel with hers. Had I still been menstruating, we might both have menstruating at the same time of month. Thanks to her regular cycle, I realized that the menopause started, since my nipples didn’t hurt anymore every time our daughter menstruated. I guess this means pheromones helped me to understand that my body is in its menopause.

There are four principal kinds of pheromones:

Releaser pheromones – they elicit an immediate response, the response is rapid and reliable. They are usually linked to sexual attraction.
Primer pheromones – these take longer to get a response. They can, for example, influence the development or reproduction physiology, including menstrual cycles in females, puberty, and the success or failure of pregnancy. They can alter hormone levels. In some mammals, scientists found that females who had become pregnant and were exposed to primer pheromones from another male, could spontaneously abort the fetus.
Signaler pheromones – these provide information. They may help the mother to recognize her newborn by scent (fathers cannot usually do this). Signaler pheromones give out our genetic odor print.
Modulator pheromones – they can either alter or synchronize bodily functions. Usually found in sweat. In animal experiments, scientists found that when placed on the upper lip of females, they became less tense and more relaxed. Modulator hormones may also affect a female’s monthly cycle.

But, there’s another kind of pheromone. Synthetic pheromones. If you search the Internet for pheromones, you come across several sites that sell pheromones. Each site claims that their pheromones are the best and they guarantee you sexual success. Up to 11 years ago I was involved in selling pheromones. Do not let those websites tell you that using their pheromones will give you men instant success with the ladies, or ladies, that men will be powerless and groveling at your feet, begging you for sex. That is not the purpose of the pheromones.

How Pheromones Work

Scientists isolated and synthesized human pheromone molecules which are nearly colorless and odorless. Then they are mixed with attractive fragrances. The pheromones mixed in with the fragrance is detected by a tiny organ in the nose, called the vomeronasal organ (VNO), which is an auxiliary olfactory sense organ. You can read more about this organ on Wikipedia. When the VNO detects the pheromones, the other person will automatically react by willingly being open because there is ‘something about you’, something they want to get to know better. Their first reaction is to trust you. The ‘ice’ is broken and they are ready to hear the first words you speak.

This last paragraph was on the website we had back then, me and my American business partner. I have tried the pheromones myself. My mom and I did it together and on the day we tested it, we encountered a whole lot of very friendly people. Strangers spoke to us for seemingly no reason, people smiled at us when they passed us, children seemed to give us extra attention. Yes, it could’ve been the pheromones we used that day, it could have been our good moods that attracted the attention or it could just have been that the sunny weather had everyone around us in a good mood too. However, when my mom had a job interview shortly after that day, she used the pheromones and she got the job. Exactly the same happened to me not long after. That makes you think, doesn’t it.

Maybe it’s the pheromones that did its work and maybe it’s because we wore the pheromones that we felt more confident and that it was our self-confidence that made us successful. I am not going to tell you that pheromones definitely works, but it’s definitely fun to try it. And even if the only thing it does is to help you feel more confident and it doesn’t do anything else it claims to do, I would say it’s a successful product.

So, you decide. Pheromones… fact or fiction?

  1. I totally agree – we do not know everything about the human body and I wonder if we ever will. I think there’s still a huge amount to be discovered, but it might take thousands of years for it to happen.

  2. Very informative. Yes, I believe in the women’s cycle being in sync. Experienced that. I will admit to a strange time (to me) when my pregnant daughter lived with us. It was a bit uncomfortable how my body reacted to “whatever” her body was giving off. From my nipples leaking to a super high sex drive to an off schedule cycle.
    I have bought pheromone body spray. The first time I used it, I noticed a difference with ppl. The few times after that I noticed no change. I just used it because it actually smelled good.
    I have seen studies about pheromones/hormones/attraction on TV. It was informative and thought provoking. One test was a group of couples. The men removed their t-shirts and left the room. Their female partners came into the room with the shirts and were asked to pick out what they thought were their partners shirt just by smelling it. Scientists were saying one way that females pick their partners by the sense of smell. I do believe in all this, only because I believe we are mammals. There is a very basic primal part of each of us. Great Post Marie!

    1. Thanks for your comment, SassyCat. Indeed, I agree, we are primal, it’s just such a shame that some people cannot tune into that anymore or refuse to follow their instincts.

  3. Sometimes fact is stranger than fiction! . . . but I tend not to think too much about the rhymes and reasons . . . just try and go with the flow.
    Interesting what you are saying about yours and your daughters cycles though as I’ve had a similar experience.
