How to prevent pregnancy without condoms

Men don’t like to use condoms because they don’t like the “membrane” created by condoms. When men don't use condoms, contraception becomes women's responsibility, and women become victims of "love". The latest contraceptive vaccine allows men to prevent pregnancy without using condoms. How could you not know about such a good thing?

During sex, do you want to throw away those annoying condoms? Experts from Nanjing Medical University in my country, together with authoritative experts from the United States and France, have successfully developed what is said to be the most advanced male contraceptive vaccine in the world. It is currently expected that the experiment will be completed in three years. Just a few injections can prevent sperm and egg from combining. This magical potion is the male contraceptive of the new era. When this vaccine is put into use, gay men will be able to throw away condoms and enjoy "love" without constraints and barriers.

In the past 20 years, scientists around the world have been developing male contraceptives, but they have not yet been put into use. Nanjing Medical University has a common topic with the United States and France, which is the development of male contraceptive vaccines. Through the joint research of many reproductive medicine scientists from the three countries, a contraceptive vaccine specifically for men has been successfully developed. Moreover, this can be said to be the most effective vaccine currently in the world.

As the main person in charge of vaccine production and molecular mechanism research explained, the male contraceptive vaccine they are studying is based on sperm surface antigens. The vaccine contains an antibody that can bind to the sperm surface after being injected into the body, making the sperm like carrying a heavy burden. The sperm can no longer move and its vitality is poor, so it has no chance to combine with the egg.

It is understood that the vaccine has been successfully tested in preliminary experiments on mice and monkeys. This is the most effective male contraceptive vaccine among the dozen or so currently under research around the world. It is equally effective on both mice and monkeys, while many other vaccines are often effective on mice but ineffective on monkeys. However, the vaccine still needs to undergo about three years of large-scale animal and human experiments to observe its toxicology, etc. Once successfully applied in clinical practice, as long as one shot of the vaccine is given every week for three consecutive shots, it can provide contraceptive effects for half a year, and condom contraception will become a thing of the past.

Currently, there are only two contraceptive methods for men: condoms and sterilization. These two methods are often rejected by many men, so contraception has become a task for women. However, birth control pills and IUDs may have adverse effects on women's health. Therefore, the National Population and Family Planning Commission proposed that men should also take responsibility for population control in the future. The "male contraceptive vaccine" project studied by Wang Zengjun and his team has also become an "Eleventh Five-Year Science and Technology Research Plan."
