Q: Can sperm be released without ejaculation?

A: Shortly before the man has an orgasm and ejaculates, it is possible for him to release some fluid, which can contain sperm. This fluid is popularly known as 'pre cum' (not a scientific term). 

The method of birth control where the man pulls his penis out shortly before he ejaculates is called 'coitus interruptus.' It has a high failure rate because it is possible for her to get pregnant from this small amount even when he pulls out and he does not ejaculate into her vagina.
