Coitus interruptus as a method of contraception

Coitus interruptus is a contraceptive method whose reliability is questionable, as it is still uncertain today whether or not there are sperm in the pre-seminal fluid. Moreover, the success of this method also depends on the timely withdrawal of the penis before ejaculation, which may not always be possible.

Finally, it is very important to remember that this method, also known as reversal, does not prevent sexually transmitted diseases (STDs).
