Question 2

What do Leydig cells do?

Question 15

What are the different parts that make up the Broad ligament?

Answer 15

Mesometrium > connects body of uterus to pelvic wall

Mesosalpinx > connects the fallopian tube the rest of the broad ligament

Mesovarium > acts as a mesentery for ovary & connects ovary to rest of the broad ligament
