In women, estradiol levels rise and progesterone, and in men testosterone levels. They are produced primarily in the gonads (ovaries in the female case and testes in the male), but can also be generated in the adrenal glands (important for stress responses) and some brain regions. in sexual activity are involved substances such as oxytocin, prolactin, serotonin, dopamine, norepinephrine, gamma amino butyric acid and opioid endogenous enkephalins and endorphins.
In the process of sex there are plenty of changes in the levels of these substances , which allows humans to enjoy the relationship, says the professor. Several studies have reported that this process is rapid muscle contractions, subsequently leading to total relaxation. Camacho, a member of the National System of Researchers, indicates that orgasm "there is almost total change in all our brains" . In his laboratory, Professor CF has investigated some of the biological consequences of love . "In biological terms, this is a complex neuroendocrine process in which emotions are expressed positive (security, confidence and euphoria) and negative (anxiety, mania and depression). " This process involves various chemical agents. So " no one can speak of a single molecule of love . Speakers significantly neurotransmitters. as serotonin and dopamine, peptides such as oxytocin and vasopressin, which form the bonds between partners, children or parents, as well as peptides Opioids are associated with pain and pleasure, " he says.
