Sexual differenciaton by default follows a pathways for development of female internal and external genitalia, requiring no active intervention. Endocrine activity of the testes, production of Androgens by Leydig cells and Mullerian Inhibiting hormone (MIH) by Sertoli cells, is required for sexual differenciation to be diverted down the male genitalia development pathway. | Sexual differenciaton by default follows a pathways for development of female internal and external genitalia, requiring no active intervention.
