Getting pregnant Pregnancy happens when a sperm fertilises an egg, which can happen even if you've not had sexual intercourse (penetration). During vaginal penetrative sex (where the penis enters the vagina) semen can be ejaculated. Semen is the liquid produced during ejaculation and contains millions of sperm.
How can a girl get pregnant at first try?
Yes, a girl can become pregnant the first time she has sex. Anytime a girl has vaginal sex with a guy, she is at risk for becoming pregnant. Even if a guy ejaculates outside of but near a girl's vagina or pulls out before he comes, a girl can get pregnant.
