- Makes cervical mucus thin and slippery so the ovum can travel through the fallopian tube easier
Progesterone
- Thickens and maintains the uterine lining for egg implantation
- Helps maintain the pregnancy
Human Chorionic Gonadotropin (hCG)
Stimulates the corpus luteum to produce progesterone to maintain the pregnancy
