Researchers at the Biotechnology Institute of the National Autonomous University of Mexico (UNAM) work on the development of a contraceptive method for men, the first of its kind in the world. This contraceptive would not have a hormonal load and once its intake is sopped, the man will be fertile again immediately and without side effects.
Claudia Treviño, a researcher at the Institute of Biotechnology at UNAM, said that the purpose of this project is to develop a drug that has effectiveness above other methods in the market, beyond 96 percent.
Treviño explained that when a woman who has used the contraceptive pill for many years in may cause difficulty to conceive once she stops taking the pill, and in many cases they need infertility treatment. With this drug, scientists seek to free women from being the only ones responsible for birth control.
There are currently two male contraceptive methods: the condom and vasectomy.
How does it work?
The contraceptive developed by the UNAM blocks the movement of the sperm, preventing it from reaching the egg.
“From the point where the sperm is ejaculated to the point where it finds the ovule it is a very long road so it has to move using its tail, beating it hard. This compound would inhibit this shaking and prevent the sperm from swimming the distance needed to find the ovule so they are not found and there is no fertilization,” said researcher Claudia Treviño.
To immobilize sperm, the UNAM researchers are proposing the use of venom of poisonous animals such as snakes, spiders and scorpions, among others. The presentation of this contraceptive would be in patches or pills. The researchers hope it could be available to the public in about five years.
