Both LH and FSH attain a peak level about.......... of menstrual cycle.

Answer

**Step-by-Step Solution:**

1. **Understanding the Menstrual Cycle:**
- The menstrual cycle is a monthly cycle that occurs in human females, typically lasting about 28 days. It involves various hormonal changes and physiological events that prepare the body for potential pregnancy.

2. **Identifying Key Hormones:**
- The two key hormones involved in the menstrual cycle are Luteinizing Hormone (LH) and Follicle Stimulating Hormone (FSH). These hormones are produced by the pituitary gland and play critical roles in regulating the menstrual cycle.

3. **Timing of Hormonal Peaks:**
- During the menstrual cycle, LH and FSH levels fluctuate. They both reach their peak levels around the mid-cycle, which is approximately 14 days into the 28-day cycle.

4. **Role of LH and FSH:**
- The peak in LH and FSH levels triggers ovulation, which is the release of a mature egg (ovum) from the ovary. This is a crucial event in the menstrual cycle as it prepares the body for potential fertilization.

5. **Conclusion:**
- Therefore, both LH and FSH attain peak levels around the mid-cycle, specifically about 14 days into the menstrual cycle.

**Final Answer:**
Both LH and FSH attain a peak level about **mid-cycle (around 14 days)** of the menstrual cycle.
