Options

A. relaxin only
B. estrogen only
C. progesterone
D. human chorionic gonadotropin

Answer

**Step-by-Step Solution:**

1. **Understanding the Corpus Luteum**: The corpus luteum is a structure that forms in the ovary after ovulation, specifically from the ruptured Graafian follicle. It is often referred to as the "yellow body" due to its yellowish color.

2. **Identifying the Main Function**: The primary role of the corpus luteum is to produce hormones that are crucial for reproductive health. The main hormone produced by the corpus luteum is progesterone.

3. **Role of Progesterone**: Progesterone is essential for maintaining pregnancy. It prepares the uterine lining for the implantation of a fertilized egg and helps sustain the pregnancy if implantation occurs.

4. **Considering Other Options**: While the corpus luteum does produce other hormones such as relaxin and estrogen, the question specifies the "main function." The term "only" in the other options indicates that they are not the primary function of the corpus luteum.

5. **Conclusion**: Based on the above points, the correct answer to the question is that the main function of the mammalian corpus luteum is to produce **progesterone**.

**Final Answer**: The main function of the mammalian corpus luteum is to produce **progesterone**.
