Reproductive systems, sometimes called sexual organs, are the sets of organs humans need to make a baby or “reproduce” (that’s where we get the name!). They are also the body parts that make men and women physically different from one another.
A man’s reproductive system includes the penis, testicles, vas deferens and prostate. Most of a man’s reproductive system including penis and testicles is outside his body.
A woman’s reproductive system is made up of a vulva, vagina, cervix, uterus, fallopian tubes, ovaries and breasts. Unlike men, most of a woman’s reproductive system is located inside her body through an opening between her legs. This opening connects several of her reproductive parts to her uterus, which is where a baby grows during pregnancy. The uterus is pretty close to the stomach, which is why it sometimes looks like a pregnant woman has a baby in her tummy.
One male and one female system are needed to reproduce, and that is why boys and girls have certain body parts that are different.
