- Cyclic menstruation refers to the regular monthly cycle of menstruation that occurs in females during their reproductive years. It is a sign of a functioning reproductive system.

2. **Identifying the Indicator:**
- The question asks for what cyclic menstruation is an indicator of. It indicates a normal reproductive phase in females. This means that the body is capable of ovulation and menstruation, which are essential for reproduction.

3. **Defining Menarche and Menopause:**

- Menopause, on the other hand, is the time when menstruation ceases, usually occurring around the age of 45.

4. **Determining the Extent of Cyclic Menstruation:**

5. **Final Answer:**
- Thus, cyclic menstruation is an indicator of a normal reproductive phase and extends between menarche and menopause.

Cyclic menstruation is an indicator of the **normal reproductive phase** and extends between **menarche** and **menopause**.
