Coitus interruptus (withdrawal) is a well used contraceptive technique. With this method intercourse takes place until ejaculation is about to occur, at which point the male pulls his penis out of the vagina before he ejaculates (comes) to keep sperm from joining the egg. The problem is that there are often sperm present in the little dribble of semen that escapes from most men prior to ejaculation so it cannot be guaranteed as a method of contraception.
This method requires a high level of trust and cooperation and couples may find it unsatisfying to use. Withdrawing before ejaculation is better than using no method at all but this method is definitely not to be recommended.
|is acceptable to most religious groups||the male may fail to withdraw or may not withdraw fast enough to prevent sperm from being released|
|strong self control is needed|
|before ejaculation, almost all penises leak fluid that can cause pregnancy.|
|does not eliminate transmission of HIV and other STDs|
|some men cannot tell when they are going to ejaculate|
|some men ejaculate very quickly, before they realize it|
extremely unreliable as a method of birth control
