No condoms, no contraceptives ... Not only spermicidal contraception, prevention of infection, but also no sense of its existence. After several years of careful research by American biologists, a more humane new contraceptive product developed through a large number of clinical experiments-"invisible condom", was approved in 2004 and quickly became popular throughout the United States. Newsweek has listed it as a hot event report for four consecutive weeks.
The survey found that traditional methods such as condoms and birth control pills are experiencing embarrassment. More than 80% of men do not have a "cold" for condoms; 82% of women are forced to choose contraceptives. Oral contraceptives can easily lead to weight gain, irregular menstruation, vaginal bleeding, and amenorrhea. Experts do not approve of the contraceptive method of the safe period and external sperm excretion. Even if a woman's menstrual period is absolutely regular, it will still lead to pregnancy due to accidental ovulation; external sperm ovulation will also lead to unexpected pregnancy because a small amount of sperm slides out in advance.
The invisible condom has obvious advantages. First, it quickly kills sperm and various viruses and has a good effect on contraception and infection prevention. Second, the foam is soft and delicate, and it is not irritating to the vagina and skin. It has no effect. In addition, the foam forms a protective film on the vaginal wall, which not only prevents damage but also enhances lubrication and enhances the fun.
Invisible condoms allow people to get rid of the limitations of traditional contraception and enjoy sex freely. This new type of safe contraceptive is not only popular in the United States, but has also entered the European markets such as the United Kingdom, France, and Germany, and has been welcomed by people.
