With respect to neurological causes, involvement of any nerve group, either central or peripheral, may lead to erectile dysfunction. Cerebral diseases lead to decreased sexual interest, possibly through over-inhibition of spinal centres. Among patients with spinal cord injury, 95% of those who have upper motor neuron lesions are capable of reflexogenic erections, 25% of patients who have lower motor neuron lesions are capable of psychogenic erections, and more than 90% of patients who have incomplete lesions of either kind retain their erectile function.21 Direct injury to the cavernosal nerve and blood supply commonly occurs during therapy for prostate cancer; erectile dysfunction is present to some extent in 80% of patients so treated, whether by surgery or external beam radiation therapy.22 But what was it about cycling that led particularly to erectile dysfunction? Goldstein's study hadn't uncovered a cause, but another study done at the University of California, San Diego, offered an explanation. The study -- done in conjunction with Serfas, a bicycle accessory company in Lake Forest, Calif. -- found that the rub lies not in cycling itself but in the seats. The drug, originally developed to treat high blood pressure and angina, might alleviate jet lag by interfering with a molecule that sends signals to the hamster brain's body clock mechanism, Golombek said. viagra at canadian pharmacy canadian pharmacy viagra What is PMS?
