The secretion of gonadotropins increase rapidly during

Options

A. ovulatory phase
B. follicular phase
C. luteal phase
D. menustral phase

Answer

**Step-by-Step Solution:**

1. **Understanding Gonadotropins**: Gonadotropins are hormones that stimulate the gonads (ovaries in females and testes in males). The primary gonadotropins are Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH).

2. **Identifying the Phases**: The menstrual cycle consists of several phases: the menstrual phase, follicular phase, ovulatory phase, and luteal phase. Each phase has distinct hormonal changes.

3. **Analyzing the Options**: The question provides four options:
- Ovulatory phase
- Follicular phase
- Uterine phase
- Menstrual phase

4. **Recognizing the Key Phase for Rapid Increase**: The question specifically asks about the phase where there is a rapid increase in gonadotropins.

5. **Reviewing Hormonal Changes**: During the ovulatory phase, there is a significant surge in LH and FSH. This surge is responsible for triggering ovulation, which is the release of an egg from the ovary.

6. **Conclusion**: Based on the analysis, the phase during which the secretion of gonadotropins increases rapidly is the **ovulatory phase**.

**Final Answer**: The secretion of gonadotropins increases rapidly during the **ovulatory phase**.
