Gonadotropins

Hormones that stimulate the gonads; includes LH (Luteinizing hormone) and FSH (Follicle Stimulating Hormone).

Progestins

A classification of hormone related to progesterone.

Cervix

The final barrier to uterine infections, keeping infection out and pregnancy in.

Ovary

The female gonad responsible for producing gametes and hormones like estrogen and progesterone.

Endometrium

Follicle

A structure in the ovary that contains an oocyte and produces hormones.
