Pheromone Science: Effects Of Copulins On Men

Happy Friday, Love Scent fans!

This week, we’re going to look into a topic that should interest male and female pheromone users alike: the effects of copulins on men.

Copulins, as you may already know, are acidic secretions found in the female reproductive system. Women produce these acids at particularly high levels during ovulation, and exposure to copulins can affect a man’s sexual desires and behavior. Because of these strong sexual effects, copulins are found in many women’s pheromone products, including some of Love Scent’s most popular pheromone perfumes.

But some men have wondered: can men benefit in some way from wearing copulins themselves? There have been rumors about the benefits of men doing so, ranging from decreased aggression from other men (perhaps because they are pacified by the scent of the copulins), to greater acceptance from women (possibly due to women feeling less threatened by men who, well, smell like women), to greater sexual interest from women (maybe because the scent of copulins on a man indicates that he has had success with other women and is therefore a good candidate for mating).

The speculations and rumors listed above are based on personal anecdotes and theorizing rather than laboratory research, but men who have worn copulins definitely have reported increased confidence and better success with women. So, what’s going on? Does wearing a distinctly female pheromone really benefit men, or are the benefits all in men’s heads?

The answer: it’s definitely not all in their heads, and men can certainly benefit from wearing copulins. Before we get into the details of why, let’s take a look at copulins and how they affect men’s behavior, and what that means for both male and female pheromone users.

In the late 1990s, researchers in Austria determined that exposure to copulins affected men’s perceptions of women and induced changes in men’s hormones[1]. Since then, other studies that have exposed men to female pheromones collected during ovulation, including on t-shirts[2] and on pads[3], have increased men’s testosterone levels. The increases in testosterone are highest when participants are exposed to copulins collected when a woman is at the “most fertile” stage of her monthly cycle. As increased testosterone has been linked to increased interest in sex and the likelihood of seeking out a sexual relationship, it’s easy to see why copulins are a popular addition to women’s sexual pheromone formulas.

Men exposed to copulins are also more likely to make risky decisions, which can make them bolder in their dating lives, and more likely to mimic a female partner’s body language and behavior. They are also more likely to rate themselves as more attractive to women, thus increasing their confidence and the likelihood that they will approach women. On top of all this, men exposed to copulins are more likely to find women attractive, which in turn contributes to an increase in sexual desire and desire to approach a woman.

But what about negative side effects? Pheromone users, particularly those who use sexual pheromones, know that these products can sometimes have unpleasant side effects, and copulins may require caution too. Copulins have been linked to mate-guarding–that is, increased possessive or aggressive behavior from men around their female partners[4]–and increased testosterone can lead to increased aggression in men. Anecdotal evidence from female copulin wearers confirms that some men may be more aggressive when exposed to copulins, but other women report an increase in a man’s submissiveness and desire to please when under the influence of copulins. The response, as with many other pheromones, probably depends on the man.

To complicate things further, a recent study conducted in 2016 found no significant changes in mate-guarding behavior in men who had been exposed to copulins[5], so we need more research to solidify the link between copulins and aggressive or possessive behavior.

So, let’s review the benefits of men’s exposure to copulins:

  • Increased testosterone >>> increased sexual desire
  • Improved self-confidence
  • Increased likelihood of finding women attractive

And the potential drawbacks:

  • Possible increased aggression
  • Possible increase in possessive behavior

So far, it’s clear why women would use copulins. Many pheromone users are hoping to increase their sexual desirability, whether they’re in a relationship or are hoping to start a new one, and copulins can certainly do that for women. But what about male pheromone users?

Men interested in copulins should consider what they’ve learned here. Would you be interested in something that increases your self-confidence? What about something that increases your feelings of sexual desire toward women, whether it’s toward your wife or girlfriend or to a potential new partner? And what about something that overall increases your interest in sex?

Based on our experiences with pheromone users, we’re willing to bet that the effects of copulins would be intriguing to plenty of men. Men in long-term relationships can benefit from a boost to their sexual desire and interest, which can lead to a more intimate, positive relationship with their partners. Men who are looking for a new partner can benefit from the increased self-confidence and improved perceptions of their own sexual desirability. And all men could sometimes use a little nudge when the time comes to take a risk in their love life!

So, back to the question we started with: can men benefit from wearing copulins? The research shows that the answer is a clear “yes” for a lot of men, though, as with all pheromones, men should pay attention to how the copulins affect them and stop using them if the effects are unpleasant. Always do what works for you!

Now that we’ve established that copulins can be highly beneficial for men, let’s take a look at some products that men might be interested in.

Master Pheromones for Men1. Master Pheromones for Men ($48.95)

Master Pheromones for Men is one of Love Scent’s most popular formulas for men. It combines pheromones, including copulins, with an intriguing cover scent. The formula was designed to elevate a man’s mood, confidence, and arousal, and it is worn for its self-effects as much as it is worn for its effects on others.

Master already contains a distinctive cover scent, so you do not need to combine it with your own cologne. It’s ready to wear right out of the bottle. We recommend wearing some under the nose to make sure you’re benefiting from the self-effects.

You can try the Master formula with a 10 ml roll-top bottle for $48.95. Order yours today!


2. Essence of a Woman ($29.95)

Our most popular product for women, Essence of a Woman also offers plenty of benefits for men. This is a very strong copulin concentrate–it contains copulins, and nothing else. One small bottle will last you a very long time. You can use this product on its own, or in combination with other pheromones.

Essence of a Woman contains no cover fragrance, but it has a very strong natural smell of its own. Because of the strong scent, this formula must be worn with a cover fragrance of some kind. Use any cover scent you like, as long as it masks the natural smell of the copulins.

If you want to try copulins, Essence of a Woman is a cost-effective way to experiment with them. A 7.5 ml eyedroppper bottle is yours for $29.95. Order now!

UPDATE: We no longer carry Essence of a Woman. Try our Love Scent Copulin Concentrate instead!


Primal Women3. Primal Women ($59.95)

Another popular women’s product that men can easily use, Primal Women contains the social pheromone AndrosteNOL and copulins. AndrosteNOL improves mood and reduces stress, and can act as a social lubricant–meaning that it could act as a counterweight to any potential negative side effects of the copulins. Primal Women mixes well with other pheromone formulas, but is also suitable for use on its own.

Primal Women does not have a cover scent added to it, and we do recommend combining it with your favorite fragrance. Use any scent you like!

Primal Women is a good choice for anyone who wants to experiment with copulins while also reaping the benefits of AndrosteNOL. You can order a 10 ml dripper bottle for $59.95. Try it today!


That’s all for today, Love Scent fans! We hope this has given you a better understanding of how copulins work, and has given any men out there the encouragement they need to try out this powerful and fascinating pheromone.
