Q

What is the embryology of the testes and how do they descend

A

Testes originate at posterior abdominal wall ~T10 level

By birth, they have descended into the scrotum by the pull of the gubernaculum

17
Q

What is failure of testes descent called

A

Cryptorchidism

18
Q

What happens in the absence of SRY protein and absence of the Y chromosome

A

Female development occurs

19
Q

In females, what do somatic support cells become

A

granulosa cells

20
Q

What are thecal cells

A

Equivalent to Leydig cells in males

21

A

endoderm

22
Q

What is the embryological origin of the inferior 2/3rds of the vagina

A

mesoderm

23
Q

What is the embryological origin of the glans penis
