Patient's question:
How to choose the right condom?Doctor's answer:
Hello, according to international standards, the longest condom is 198 millimeters, with a sheath thickness of 0.06 to 0.07 millimeters, and ultra-thin thickness is only 0.03 millimeters. The average weight of a condom is 1.4 grams, and its elongation should be 7 times its original size. It takes 13 kilograms of force to tear it in half. In our country, there are three sizes of condoms: large (35 millimeters), medium (33 millimeters), and small (31 millimeters).Correct selection and proper use of condoms directly affect contraceptive effectiveness and disease prevention.
First, one should strictly select condoms. Choose the style and size that suits your needs based on the size of your penis and your partner's preferences. When selecting, make sure they are produced by reputable manufacturers, as many condoms on the market are counterfeit or substandard products. After purchasing condoms, open the package to check if they are expired or moldy. Before use, also check if they are leaking or damaged.
Second, use condoms correctly. Condoms must be used throughout the entire sexual activity. Some people only put on condoms when they are about to ejaculate, which may lead to contraceptive failure. During sexual intercourse, the pre-ejaculate fluid may contain a small amount of seminal fluid from accessory glands. This fluid may very well contain sperm, and if these sperm enter the vagina and reach the uterus, they may combine with the advancing egg, leading to pregnancy.
