all fetuses in the womb are female until about the fourth month of gestation, then the Y chromosome induces production of male hormones that force the physical changes in the female to create the male testes from the female ovaries and prevents the formation of the uterus. Without the uterus, there is no need for a vaginal canal, so seminal fluid is directed through the same outlet as the urine.
