British researchers: Wan Ai may weaken male fertility

British medical researchers have warned that takingdrug used to treatdysfunction inmen"Wan Aike"( commonly known as Viagra ) , which could damage male fertilitythe team, led by Dr David Glenn, a consultant gynaecologist at Queen's University Belfast,, came to the conclusion through two sets of experiments, theObserver reported
ThursdayIn the first set of experiments
researchers immersed semen samples taken from volunteers in a low-concentration "Wan Aike" solution, with the same concentration ofsolution as the "Wan Aike" concentration in the blood after the man took a 100 mg dose of the Wan Aico pilllater, researchers compared these semen samples with standard semen samples , found that Wan Aike can damage sperm head proteinwhile while enhancing sperm activity Sperm cephaloproteins can produce enzymes that break down the surface membrane of the egg cells, allowing the sperm to enter the egg cells and form a fertilized egg The second group is animal experiments The researchers found that when mice took "Van Aiko," their sperm reduced the ability of egg cells to fertilize by 40 percent But there is no evidence that mice born after taking Van Aiko suffer any damage as a result " These findings raise major concerns about two things,
" Glenn said Our work reveals the possibility that taking 'Wan Aike' may have an effect cumulative, which can cause serious reproductive problems later in the year warned that some medical institutions give male patients "Wan Aico" to increase the probability of their spouse getting pregnant And according to Glenn et al., for couples who already have reproductive problems, the use of "Wan Aike" may be just exacerbating those reproductive problems Glenn et al.'s study will be published in the American journal Fertility and Infertility
