Doctors offer a new method of contraception for men as an alternative to vasectomy. Unlike vasectomy, the new method is non-operative. Its advantage is that the process is reversible and the fertility possibilities can be restored again if the man wishes. Instead of removing the seminal canal, scientists from Seattle propose to introduce a silicone tube into it, which does not let the sperm through. The success rate of the method is high according to clinical research data. According to the volunteers, already on the second or third day after the manipulation, they feel in condition. Restoring fertility after vasectomy requires a much longer period and is associated with unpleasant sensations from the operation.
