Erectile dysfunction and testosterone level

Men who have erectile dysfunction and low testosterone may get no additional help from adding the hormone to their Viagra instruction, a new study suggests.The first-selection treatments for erectile dysfunction are drugs called PDE5 inhibitors, which include sildenafil (Viagra), vardenafil (Levitra) and tadalafil (Cialis). They travail by helping the smooth muscles of the penis to modify, which increases blood stream. When men with erectile dysfunction also have low testosterone levels, doctors often prescribe testosterone gel along with a PDE5 inhibitor. But now a new clinical experiment of 140 men with erectile dysfunction and low levels of testosterone puts that treatment association into question. “We had expected to see some added good from testosterone,” said lead researcher Dr. Matthew Spitzer, an endocrinology person at Boston University University of Medicament. “But that’s not what we observed.” Researchers organize that, over 14 weeks, men who were randomly assigned to take Viagra plus testosterone gel did no better than those given the medication plus a hormone-at liberty placebo gel.
