Which hormone initiates the preparation of the endometrium of the uterus for pregnancy?
- A. FSH
- B. Estrogen
- C. LH
- D. Progesterone
Correct Answer: B

It is essential for creating a suitable environment for implantation of a fertilized egg. FSH (Follicle Stimulating Hormone) is involved in stimulating follicle development in the ovaries, LH (Luteinizing Hormone) triggers ovulation, and Progesterone is crucial for maintaining the endometrial lining post-ovulation and during early pregnancy.
