The Reproductive System in People Who Can Become Pregnant
People have reproductive parts on both the outside and inside of their bodies. These parts are called “reproductive organs” or genitals. In a person who can become pregnant, all the parts on the outside are together called the vulva. Sometimes people may use the word vagina for this whole area. But the vagina is the part that begins as an opening in the vulva and leads inside to the womb. The vagina is sometimes called the birth canal.
Breasts come in all shapes and sizes. They start to grow during puberty, usually when a person is between 10 and 15 years old. Breasts develop further during pregnancy, and make milk following birth. For some people, sexually touching the breasts can cause pleasure and vaginal wetness.
