Corpus luteum releases:

Options

A. Luteinising hormone
B. Estrogen
C. Progesterone
D. Both B and C.

Answer

**Step-by-Step Solution:**

1. **Understanding Corpus Luteum**: The corpus luteum is a structure that forms in the ovary after an egg has been released during ovulation. It plays a crucial role in the female reproductive system, particularly in establishing and maintaining pregnancy.

2. **Hormones Released by Corpus Luteum**: The corpus luteum primarily releases two hormones: estrogen and progesterone. Both of these hormones are essential for preparing the uterus for potential implantation of a fertilized egg and supporting early pregnancy.

3. **Evaluating the Options**:
- **Option A: Luteinizing Hormone (LH)**: This hormone is produced by the anterior pituitary gland and is not released by the corpus luteum. Its primary function is to trigger ovulation and regulate the menstrual cycle.
- **Option B: Estrogen**: This hormone is released by the corpus luteum and is important for the development of female secondary sexual characteristics and the growth of the uterine lining.
- **Option C: Progesterone**: This hormone is also released by the corpus luteum and is crucial for making the uterine lining suitable for implantation and supporting early pregnancy.
- **Option D: Both B and C**: Since both estrogen and progesterone are released by the corpus luteum, this option is correct.

4. **Conclusion**: The correct answer is option D, which states that the corpus luteum releases both estrogen and progesterone.

**Final Answer**: The corpus luteum releases both B (Estrogen) and C (Progesterone).
