Q1. What are the types of reproductive hormonal feedback control?

Background

Topic: Endocrine Regulation in Reproduction

This question tests your understanding of how hormones regulate reproductive processes through feedback mechanisms.

Key Terms:

• Examples: GnRH, LH, FSH, estrogen, progesterone.

Step-by-Step Guidance

1. Identify the main hormones involved in reproductive feedback (e.g., GnRH, LH, FSH, estrogen, progesterone).

2. Describe how negative feedback works in the hypothalamic-pituitary-gonadal axis.

3. Explain an example of positive feedback in the reproductive system (such as the LH surge before ovulation).
