New contraception: Injecting silicon causes obstruction of the vas deferens

The blockbuster silicone injection is a new method of contraception given by British firm Shepherd. When needing to restore fertility, surgery can be done to get silicon gel . Shepherd has researched and released a new product called Intra Vas Device or IVD.

IVD has been tested for 2 years with the participation of 30 volunteer men. All of these people had the necessary number of children, and wanted vasectomy.

IVD is a silicone gel that is injected through the skin of the scrotum directly into the vas deferens to the vas deferens to prevent ejaculation during intercourse. When it is necessary to restore fertility, silicone gel can be removed by microsurgery to stitch the vas deferens. This is a method to prevent men from taking hormones. It is possible to have local surgery, less invasive and able to recover when needed.

Initially, the researchers appointed male volunteers in St Paul, Minnesota, but when deployed, due to the effectiveness of the new method, there was no vasectomy, so many men asked to be tested.

The main obstacle to this method of contraception is that, theoretically, IVD can create a pressure in the vas deferens, does this affect the spermatogenesis in the testicles? To proactively prevent this risk, Chinese researchers are looking for ways to allow a small amount of semen to pass through, creating pressure again but not enough to conceive.

Although it is a contraceptive method that users cannot set and remove themselves, but according to Dr. Richard Anderson of Edinburgh University, who has for many years studied male hormonal contraceptives in the UK will be an attractive choice because when needed, fertility can be recovered.

Evidence is a recent study of more than 9,000 men in 9 countries in 4 continents, of which more than 60% of men are Spanish, German, Mexican and Brazilian, said they are ready to use measures. This new contraceptive, because they want to ease the burden on their partners.
