Patient's question:
What is the probability of conception through coitus interruptus? Why is there no absolutely effective method of contraception?Doctor's answer:
The contraceptive method of withdrawal (coitus interruptus) is quite risky. The pre-ejaculate fluid secreted by men during foreplay contains a portion of semen. Moreover, do not place too much trust in a man's control, as it is difficult to guarantee absolute safety by withdrawing the penis before orgasm. In fact, most men experience pre-ejaculate leakage, and the number and motility of sperm are sufficient to cause pregnancy. Even if ejaculation occurs outside the vagina on the vulva, pregnancy is still possible. Active sperm may enter the vagina and continue to move towards the uterus, causing pregnancy in women. It is recommended that you pay attention to your menstrual cycle and use a pregnancy test kit around 7-10 days after a missed period. Alternatively, you can visit a hospital for an ultrasound or blood test to more accurately determine whether you are pregnant.
