You may find the following scientific explanations interesting to read:
- Pheromones are chemical substances excreted by men to trigger reproductive behavioral response from a woman. Women have structures in the nerve cells lining the nose that can detect these Pheromones.There are many reputable and credible scientific studies that have been performed that validate the role of pheromones in mating behavior and as the driving force behind all sexual attraction in women. Pheromones secreted by men attract women causing an increase in the luteinizing hormone (LH) in women, thereby causing a woman to have a heightened sexual responsiveness to a man. This LH surge elevates a woman’s predisposition towards sexual activity.
- Dopamine: There is a combination of things that come in effect when it comes to an orgasm in the brain. Neurotransmitters dopamine in particular for example, is heavily involved in the sexual response. There is some evidence showing that oxytocin (produced by dopamine) levels increase during sexual arousal and orgasm in women.
- HLA (human leukocyte antigen) : are large number of genes in humans. This group of genes reside on chromosome 6, although being attracted physically to someone by itself is not inherited, some people inherit a characteristic, or characteristics, which give them a special susceptibility to be attracted to certain people (you like blond or red head….etc). Among the most widely studied of inherited characteristics in people is the system of human leukocyte antigens (HLA), Your particular set of HLA genes is unique, however, credible mechanism is sexual attraction in which females are able to detect males with different HLA relative to their own type.
