oestrogen
progesterone
where do the ovaries develop?
on the posterior abdominal wall
where do the ovaries move to after development and how?
onto the lateral wall of the pelvis
assisted by the round ligament of the uterus
what is the vagina?
a muscular tube
describe the normal position of the walls of the vagina

examining finger in the lateral fornix
feel in the 4 and 8 o clock positions
