What is indicated by the cessation of menstruation?

The cessation of menstruation, known as amenorrhea, signifies that the menstrual cycle has halted, which can lead to infertility. This is because, without menstruation, the ovulation cycle may also be disrupted or halted entirely. The hormonal balance necessary for regular ovulatory cycles has shifted, indicating that the ovaries may not be releasing eggs, which is essential for conception.

In contrast, increased estrogen production, irregular ovulation, and recurrent menstruation do not accurately describe the implications of menstruation stopping. Increased estrogen typically occurs before menstruation when the body is preparing for ovulation. Irregular ovulation indicates that some menstrual activity is still occurring, and recurrent menstruation suggests that menstruation is still taking place, which contradicts the notion of its cessation. Thus, the correct understanding centers on the ending of the menstrual cycle and its implications for fertility.
