What is the normal standard for a small penis?
Before the 9th week of the embryo, the fetus has no gender difference. Whether the external genitalia differentiate in the male direction depends on whether there is the effect of androgen. For example, the size of the penis, the length of the penis, and the size of the testicles have a relatively normal range. However, this normal range is usually based on the standard after maturity. In terms of the length of the penis, it should be 4.5-8.6 cm. The size of the testicles should be 15 ml in volume.
