The testis makes two major hormones involved in sex determination-

-Anti-Müllerian hormone (AMH), causes the Müllerian duct to regress.

-Testosterone, causes differentiation of the Wolffian duct into the male internal genitalia.

Induced pluripotent stem cell (iPSC) with the pluripotency of an embryonic stem cell. These genes were 

a. Sox2 and Oct4 (Oct3, Oct3/4, and Pou5f1) -which activated Nanog and other transcription factors that   established pluripotency and blocked differentiation

b. c-Myc which opened up chromatin and made the genes accessible to Sox2, Oct4, and Nanog

c. Klf4 -which prevents cell death
