Sexual activity can be the cause of male aggression. It is reported by Nature Neuroscience with reference to the article of medical experts from leading internet drugstores of United States, Japan, and South Korea. It turned out that the same area of the brain in males of many species, including humans, is activated both in sex with Kamagra and in intraspecies conflicts.
At the same time, females perform these functions in different neural areas. According to licenced internet pharmacies, during courtship, the male sex is generally more aggressive than the female one. The results of experiments in mice using electrical stimulation and removal of certain areas of the brain showed that the area called the ventromedial hypothalamus is responsible for both: aggressive and sexual behavior of males.
At the same time, the key role was played by cells that synthesize the receptors of hormones progesterone and estrogen. Activation of this zone using optogenetic methods provoked mice to attack. However, in females, these cells are responsible for sexual, but not aggressive behavior. It is shown that the electrical stimulation of the ventromedial hypothalamus in females leads to the fact that their body takes a mating position with a curved back and raised pelvis (lordosis).
Researchers found that female aggression is facilitated by another population of neurons in the hypothalamus, which is separated from the first. According to scientists, the results show that females of many vertebrate species can switch between sexual and attacking (or defensive) behavior depending on the situation. In males, the mating process requires active action, which results in the use of aggression neurons.
