Canadian researchers have found that a hormone generated during pregnancy may be a potent tool in fighting multiple sclerosis,the crippling disease of the central nervous system, according to a new report.Taking note that MS often goes into remission in pregnant women, scientists at the university of calgary studied the way that the hormone prolactin, generated during pregnancy, acts to protect myelin, the all-important substance which coats nerve cells and helps conduct messages through the central nervous system. Studying mice, the scientists showed that prolactin helps the formation of new myelin, according toa summary of their research. In people with MS,myelin is attacked and damaged by the body's own immune system.
A man usually needs about two or three minutes of stimulation to have an orgasm,a woman generally needs 10 times more. For a man,an orgasm is instinctive.For a woman,it happens only after direct stimulation of the clitoris. A man's climax usually lasts for 10-13 seconds.For a woman,it lasts 6-60 seconds. A man must recuperate after an orgasm but a woman can have repeated orgasms within minutes or in rapid succession. Wonder why a man rolls over and sleeps after? During sex,his body releases oxytocin,a hormone that induces drowsiness.A woman is more relaxed after sex,which is why she wants to talk or cuddle.
