German scientists have developed a "semen switch" that weighs only two grams and is inserted into the scrotum.
It can be used to "switch on" or "switch off" your fertility by squeezing the spermatic cords. The concept was developed several years ago, but now researchers are confident that it can already be used in practice.
I read this in the news. It's funny. Because here they whine about HRT causing a "terrible" side effect associated with the fact that sperm is no longer produced. Meanwhile, a sperm switch has been developed for men as a method of contraception, and it is expected that it will be in high demand, since the orgasm remains, but the semen is not released.
