Why do boys have penises, and girls don’t?
The questions kids ask us about science aren’t always the easiest to answer.
During the 9th week after conception, a baby’s genitals start to form. At this point, the baby’s sex isn’t determined yet as it only has what are called “indifferent gonads,” which have the potential to develop either testicles or ovaries.
The process development may be different for everyone, but gender really comes from a variety of areas both on the inside and outside of the body. For some, the penis is created by complex interactions between hormones and chromosomes.
