Step-by-step explanation:
The most common cause of ovulatory dysfunction in reproductive age women is polycystic ovary syndrome (PCOS). PCOS causes hormone imbalances that can interfere with normal ovulation, leading to anovulatory cycles. Another possible cause of ovulatory dysfunction is primary ovarian insufficiency, which is when the ovaries stop working normally and producing viable eggs at a relatively early age.
Diagnosing the cause of ovulatory dysfunction generally requires monitoring signs of ovulation, such as using an ovulation test kit or ultrasound of the ovaries. It is important to note that diagnosing the specific cause of ovulatory dysfunction may require additional testing and evaluation by a healthcare professional.
