Neurobiology of Human Sexuality :: Biology Essays Research Papers

Neurobiology of gay SexualityHuman informality is a topic that has been taboo for many centuries. The orgasm, for example, is one picture of sexuality that has been overlooked. In particular, the female orgasm is an important function to reference book because its a subject that has been socially steeped in silence and shame, and is directly committed to female health in general. Not many people are willing to admit, that orgasms actually benefit a woman physically and psychologically in many ways (i.e. easing workforcestrual cramps to alleviate stress). ace mystery about the female orgasm is why some women thespian orgasms during sexual activity. One thing that is for sure, is that even though the male orgasm is reached quicker, the female orgasm is capable of repeated pleasure. Why do so many women have difficulty experiencing an orgasm and why do men climax so fast? Interestingly enough, most women will pretend that their partners do not give them orgasm. Instead, they a llow themselves to have orgasms. Not unless that, but they can have a variety of different types of orgasms at the same time. (i.e. clitoral orgasms, G-spot orgasms, vaginal orgasms, ejaculatory orgasms, blended orgasms, etc). Men will translation for example, that the scent of a woman is what drives them crazy during sexual activity and makes them ineffectual to hold the sensation for long. So do women have more realise over physical pleasure in the brain than men? How do sexual problems happen in the brain? There is a conspiracy of things that come in effect when it comes to an orgasm in the brain. Neurotransmitters, and neuro-peptides for example, are hard involved in the sexual response. To reach an orgasm, the central nervous dodging sends orders to the heart, so that it pumps faster, sending blood to oxygenate the increase of blood period in muscles involved in sexual activity. Nitric oxide, serotonin, dopamine, epinephrine, and norepinephrine, are in force(p) a few of the neurotransmitters and neuro-peptides involved in sexual activity. Nitric oxide (NO) plays a critical role in both male and female sexuality. In penile erections, NO stimulates the release of guanylate cyclase, which, in turn, converts GTP to cGMP and produces relaxation of smooth muscles and change magnitude blood flow into the penis. This information is used in the popular medicate sildenafil (ViagraTM) that inhibits the metabolism of cGMP to prolong the effects of the erection. (1) Serotonins role in sexual function is that of constriction of smooth muscles in the genitals, and peripheral nerve function.
