While men have only three methods of preventing pregnancy at this moment, women have a wide range of such methods that are more than ten in number. Women can resort to birth control through contraceptive and the morning after pills, diaphragms, cervical cap, intrauterine devices, and even implants. At this moment, men can use condoms and the withdrawal method which typically has a low rate of success. There is one more possibility for men which is the vasectomy. However, this can be a too intrusive operation for some. In light of growing demand for an effective male contraceptive, a new study came up with VasalgelTM.
New surveys detected a larger demand for an innovative male contraceptive that has high chances of success. Not only bachelors but also 20% of couples are willing to try an effective male method for birth control. This is why a new clinical study has given full attention to an innovative contraceptive method. The new product is called Vasalgel, and it showed great potential among primates.
The new Vasalgel is a strong molecular weight polymer which is based on SMA that are styrene-alt-maleic acids. These acids are then dissolved in dimethyl sulfoxide, and the result is the most versatile male contraceptive ever to enter the consumers market. The final shape of the product is a gel that can be injected in the vas deferens. This procedure has as its main goal to fully obstruct the passage of sperm.
The gel is flexible enough to release the pressure of a blockage. The fluids can get past the obstacle, but only in small portions at a time. The effects of the Vasalgel can be easily reversed with a second shot of a solution of sodium bicarbonate. However, this procedure has been tried only in rabbits, and the results were successful.
On the other hand, the main procedure of the new male contraceptive has proved to be effective in monkeys. The team of scientists from the University of California had a group of 16 monkeys to test the new solution. Out of these, ten of them were already fathers. After two periods of breeding, no female monkey became pregnant during the research.
Even though this is a simpler operational procedure with fewer side effects than a vasectomy, few health care companies showed interest in the new product. On the other hand, the product still has to go through a human trial to prove its potential for the market.
