Final answer:
The most common cause of reproductive-aged ovulatory DUB is ovulatory dysfunction, diagnosed by menstrual history and treated with hormone therapy. PCOS is a common cause of female infertility, diagnosed with hormonal evaluation and ultrasound, and treated with ovulation induction.
Step-by-step explanation:
The most common cause of reproductive-aged ovulatory dysfunctional uterine bleeding (DUB) is ovulatory dysfunction. To diagnose DUB, a thorough menstrual history is taken to understand the pattern of bleeding and any related symptoms. Treatment typically involves hormone therapy, which can regulate the menstrual cycle and reduce abnormal bleeding. In the context of diagnosing and treating female infertility, it is important to assess for ovulation, which can be done with home ovulation test kits, blood tests, or ultrasound imaging. If the ovaries are found to have multiple cysts and other symptoms such as irregular menstruation or excess androgen levels are present, a diagnosis of Polycystic Ovary Syndrome (PCOS) may be suspected. Treatment for PCOS-related infertility may include ovulation induction to help the ovaries to produce viable eggs for fertilization.
