Patient's question:
Can retrograde ejaculation also lead to pregnancy?Doctor's answer:
Hello: It is possible! The withdrawal method of contraception refers to the practice where, during sexual intercourse, the male partner interrupts the act at the moment of impending ejaculation, quickly withdraws his penis, and discharges the semen outside the female's vagina to achieve contraception. This is an ancient form of birth control.The withdrawal method, although simple, has a high failure rate. The reason for failure is that a small amount of semen may have already entered the vagina before the male withdraws his penis. Since the act of nearing ejaculation and actual ejaculation are continuous, the time between them is extremely short. Most men cannot accurately the timing, leading to failure in withdrawing the penis from the vagina in time just as they are about to reach orgasm. This allows the first semen to enter the female's vagina, and since this initial semen contains the highest number of sperm, it increases the likelihood of pregnancy.
Additionally, a small amount of sperm may enter the vagina before ejaculation occurs. This is due to sperm stored in the vas deferens, which, during sexual arousal, are released into the urethra first through the contraction of the vas deferens, and then spill into the vagina along with urethral secretions. This pre-ejaculate sperm leakage is uncontrollable and can also result in contraceptive failure.
The withdrawal method is also known as coitus interruptus. To prevent semen from entering the vagina, both partners (especially the male) become highly tense during intercourse and may abruptly interrupt the act during orgasm. This can disrupt the occurrence of orgasm and lead to a lack of sexual satisfaction. Over time, this may result in nervous exhaustion, and some men may experience sexual dysfunction.
