The correct Answer is:
To determine what influences the formation of the corpus luteum, let's go through the steps systematically: ### Step 1: Understand the Corpus Luteum The corpus luteum is a structure that forms from the remnants of the Graafian follicle after ovulation. It is responsible for secreting hormones, primarily progesterone, which is crucial for maintaining pregnancy. **Hint:** Remember that the corpus luteum is formed from the Graafian follicle after ovulation. ### Step 2: Identify the Role of Hormones The formation of the corpus luteum is closely linked to the process of ovulation. Ovulation is triggered by specific hormones. **Hint:** Focus on which hormones are involved in the ovulation process. ### Step 3: Recognize the Key Hormone for Ovulation The hormone that primarily triggers ovulation is Luteinizing Hormone (LH). LH surges just before ovulation, leading to the release of the secondary oocyte from the ovary and the subsequent formation of the corpus luteum. **Hint:** Think about which hormone peaks right before ovulation. ### Step 4: Evaluate Other Hormones - **FSH (Follicle Stimulating Hormone)**: This hormone is involved in the growth and maturation of ovarian follicles but does not directly cause the formation of the corpus luteum. - **Progesterone**: While it is produced by the corpus luteum, it does not influence its formation. - **PRL (Prolactin)**: This hormone is related to lactation and does not play a role in the formation of the corpus luteum. **Hint:** Consider the functions of each hormone and how they relate to the formation of the corpus luteum. ### Step 5: Conclusion Based on the above analysis, the hormone that influences the formation of the corpus luteum is **Luteinizing Hormone (LH)**. **Final Answer:** The formation of corpus luteum is influenced by **LH (Luteinizing Hormone)**.
