In males, ________ prevents the internal embryonic structures from developing into female organs such as a uterus.

A) testosterone
B) dihydrotestosterone
C) estrogen
D) Mullerian duct inhibiting hormone

Mullerian duct inhibiting hormone (MDIH) is a hormone secreted by the fetal testes that suppresses the development of female reproductive organs (specifically the uterus and fallopian tubes) in males. Testosterone and dihydrotestosterone are androgens responsible for the development of male external genitalia and secondary sex characteristics. Estrogen plays a role in female reproductive function and development of secondary sex characteristics in both males and females.
