How do Endogenous pheromones work?

I have some burning questions I hope can be answered.
I believe pheromones play a major role in attraction and I would like to understand them better.

So my questions are:

Ignoring supplemental/synthetic pheromones…

  1. Are there better and worse profiles(broader or stronger appeal), if so do they correlate with physical appearance?

  2. If you find someone’s profile(scent) attractive is it much more likely they will find yours attractive too?

  3. Is there a way to change your natural profile endogenously, eg food, strengthening your immune system or using genetic drugs? I do not mean strengthening it but actually changing it.

  4. At what distance do endogenous pheromones play a role and how soon can we be judged on them?

  1. It’s not clear we consciously perceive mones, but, they do affect behavior.

  2. The lack of a good tool to measure metabolism daily makes obtaining objective measurements harder. A urine stick test (compare diabetes strips) would be ideal and possible in future.

  3. For now, urinalysis of DHEAS is a could marker for androgen metabolites.

  4. Any attempts at high serum T naturally would have to be monitored via analysis of DHEAS, etc.

  5. Vitamin D is reported to raise T levels. This could be verified by measuring T itself and key metabolities thereof. D and T metabolites have phero properties. The latter are indicators of masucline characteristics in men and women.

Let me try to give you a partial answer.

Vitamin D can raise testosterone levels.

Testosterone - Wikipedia, the free encyclopedia

And it seems that bacteria (axillary microflora / ACB) could transform free testosterone (16 androstenes - non odorous) into androstenol and androstenone.

One would measure that T is increased in blood and on axillary skin. The microflora must be normal and allowed to convert T into pheromones, before the precursors, bacteria or phero metabolites of bacteria are washed away.

Don’t wash underarms for a long time. Nature will do the job, if there is T there.

Any medical cause of insufficiency (infertility) could lower phero output; the phero output here being a red light/green light of basic fertility. Making an exact correlation between supplementation and subsequent phero output, other than stronger body odor, is more difficult without analysis of the underarm sweat per se.

Thanks that helps.

I might make another thread or try look in to it myself but it is related so I will ask here. I am wondering if there is a higher divorce rate for couples who both smoke (both, as I think I remember there is when only 1 smokes).
I could be wrong but I imagine smoking would weaken pheromone effect either through masking it or weakening the immune system.
And I know the answer doesn’t completely conclude it would be due to pheromones, it could just be that smokers are less willing to conform to others expectations of them or that they are less tolerant to stress. But I am hoping smoking has been studied in the pheromone community.

It seems health does certainly affect the natural mone signature an individual gives off, and I’m fairly certain I’m not the first to make this statement.

I quit smoking 2 months ago, and the consequential healing taking place makes me feel a lot better which in turn boosts my confidence. It could very well be the lack of negative self talk compared to before, since i have a relative who treats lung cancer which made me feel extremely guilty for smoking.

Regardless, we all know that pheremone’s are our body’s nonverbal way of communicating with others of our own species. If both partners are smokers, and their health is compromised as a result, their phero signatures would theoretically convey the same, telling the other partner that they are less fit for mating as the phero signatures of other people an individual may pick up.

Don’t forget that medications can alter your chemistry as well (Accutane changes sebum production, birth control, anti-depressants, diuretics, etc) Many people use anti-bacterial soaps to reduce acne or for medical purposes which can lead to over-growth of resistant bacteria while reducing the flora that change your odor/signature.

This topic has become more and more interesting to me as time goes on. As with all things endogenous, there are precursors to hormones.

Soy based products have been shown to increase estrogenic activity in human beings, as have green tea.

Now, as human beings we can engage in activities that actively produce certain hormones. For instance, there was a study done by harvard i believe, that tested people “posing” either confidently or submissively for 5 minutes prior to the evaluation.

The people who posed confidently showed a higher percentage of testosterone, whereas the people who posed submissively showed a higher percentage of cortisol, a stress hormone.

This directly influenced the confidence the individual had to “gamble” or take a risk.

soy products and other plants produce “phyto-estrogens,” they have higher affinity for estrogen receptors but a weaker net effect than regular estrogen. Just important to recognize that:

They beat your own estrogen to the place where it transfers the signal to the rest of your body, but it only sends a weak message. So technically, if consumed in large doses, it can out-compete your natural producing estrogen and produce LESS of an estrogenic effect.

Noted. Thanks for verification ladyscientist.

Just to confirm, do you mean that ingestion of high amounts of phyto estrogens has a counterproductive effect on estrogen? by binding to the estrogenic receptors, and preventing the effects of estrogen?

The phenolic ring of plant estrogens (three double bonds) makes them mimic animal estrogens.

not counter-productive, still an estrogenic effect just not as strong as your own estrogen.
