Summary Introduction
Introduction:
Some of the male and female reproductive organs are homologous, which are related and share a common developmental path. For example, vas deferens and oviduct are male and female reproductive organs, respectively. Vas deferens carries sperm and oviduct carries the egg. Scrotum and labia majora are homologous reproductive organs in male and female, respectively.
