Theories from past copulin research that have been proven false:

THEORIES DEBUNKED:
Copulins are Pheromones. It has been widely accepted by the hormonology community that copulins are a form of pheromone. Copulins do behave like pheromones, but are chemically dissimilar to any other compound that is regarded as a pheromone. It is my belief that copulins should be placed within a class by themselves.  UPDATE: Copulins DO act like pheromones in one instance, and that is they do appear to become airborne.

Copulins increase feminine attractiveness: To date, no copulin studies have proven that copulins increase male perception of female attractiveness. These claims, similar to those for pheromones, have been assumed because of the incorrect association with pheromones. Given that copulins are transmitted during copulation, for them to affect male perceived attractiveness of the female mate would be redundant for apparently the male has already accepted the female's attractiveness enough to mate with her!

Copulins enter the bloodstream via penile capillaries: Again, this deduction was based on assumptions. Unlike pheromones, copulins take much longer to trigger the target brain. Pheromones, once detected by the vomeronasal organ, never enter the bloodstream; once triggering the VNO, a message is sent directly to the brain via the nervous system. Hence, pheromone triggers are almost instantaneous. Copulins, on the otherhand, travel through the penile duct and into the gonads where they are then transmitted by the bloodstream directly to the hypothalamus. Prolonged transmission of copulins can literally flood the hypothalamus by 80%. Note that pheromones NEVER enter the human brain.

Some women have stronger copulins than others: There are too many factors to consider to be able to confirm this. First, the more vaginal fluid produced, the better the results. Second, a woman's vaginal walls that don't contract will be slower to transmit the copulins into the penile duct. And third, women who have been with their mates longer, and have established a frequent routine of coupling are more effective than women who have not been with their partners long, or are sporadic couplers.

After continuous exposure to copulins, the male hypothalamus alters itself to better accept copulins: My studies have shown that it is the copulins themselves that break down the male hypothalamus resistance to their effects. Normally, the hypothalamus secretes releasing and inhibiting hormones. These function to cause other glands in the body to secrete hormones, so the hypothalamus is the "power behind the throne", because it controls all other hormone triggers in the body. The more often copulins are transmitted to the male hypothalamus, the quicker they take effect, because the copulins themselves inhibit the hypothalmus from remembering how to correctly function when a foreign agent enters it. The hypothalamus "thinks" the copulins are its own hormones and allows the copulins to shut down its own directive. The copulins, not the hypothalamus itself, mutates the hypothalamus for its own purposes.

Copulins detect male testosterone or sperm: No, copulins detect male semen.

Copulins play many roles: Researchers stated that copulins did many things, including opening the penile duct, desensitizing the penis tissue, holding the penis in place, and seeping into the penile duct. All of these functions are actually performed by supporting fluids that copulins cause the female vagina to produce. Copulins are not a fluid, but a chemical suspended in a fluid. Thus, all of these roles are different fluids, not copulins themselves.
