Which hormone is primarily responsible for preparing the reproductive tract for pregnancy?

• A. Estrogen
• B. Gonadotropins
• C. Follicle stimulating hormone
• D. Leutinizing hormone

Answer: (A)

Estrogen plays a crucial role in preparing the reproductive tract for pregnancy. This hormone, primarily produced by the ovaries, helps to transform the endometrial lining of the uterus, making it thick and rich in nutrients, which is essential for the implantation of a fertilized egg. Additionally, estrogen helps regulate other reproductive hormones and promotes changes in the cervix and vaginal environment conducive to sperm transport and fertilization. Other hormones, such as gonadotropins, follicle stimulating hormone (FSH), and luteinizing hormone (LH), primarily play roles in the earlier stages of the reproductive cycle, such as follicle development and ovulation. Though they are critical in the overall reproductive process, they do not have the same direct impact on preparing the reproductive tract for early pregnancy as estrogen does.
