Many scientific studies have demonstrated that women who produce higher than average amounts of female pheromones(also known as copulins) have greater success with men. These are the women that men are unable to resist because they’reexciting, seductive, desirable — and they have that alluring quality that men fall in love with. Oftentimes, these women are notmore beautiful, sexier or more charming than most other women. They just have the edge because they produce more copulins than the average woman.
According to Vienna University biologists, Karl Grammer and Astrid Jtte, copulins block a mans ability to judge a woman’s attractiveness by the way she looks and the sound of her voice.
