Patient's question:
Is a condom not a 100% effective measure for contraception?Doctor's answer:
Condoms have a very high success rate in preventing pregnancy, nearly reaching 100%. However, this is conditional:1. The quality of the condom must be good, such as: sufficient capacity at the tip to ensure sperm does not leak out due to being too small; a diameter that fits properly so it does not fall off midway; no defects or pinholes (otherwise, under the dual friction of the penis and vagina, the condom may break).
2. Proper and standardized use, such as: expelling air from the tip of the condom before putting it on the penis; ensuring the condom's diameter matches the smallest circumference of your penis; withdrawing the penis immediately after ejaculation before it becomes soft, and placing it far away from the woman's vagina.
