**Core Concept**
Dysfunctional uterine bleeding (DUB) refers to abnormal uterine bleeding in the absence of any identifiable organic cause. It is often associated with hormonal imbalances, particularly anovulatory cycles, and can be categorized into two main types: estrogen-dominant (unopposed estrogen) and progesterone-dominant (withdrawal bleeding).

**Why the Correct Answer is Right**
The treatment of DUB aims to regulate menstrual cycles and alleviate symptoms. Hormonal therapies are commonly used, including combined oral contraceptives (COCs) to suppress ovulation, progestins to induce withdrawal bleeding, and GnRH agonists to induce a temporary menopausal state. In some cases, antifibrinolytics like tranexamic acid may be prescribed to reduce menstrual blood loss.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is not a treatment for DUB.
**Option B:** This option is not a treatment for DUB.
**Option C:** This option is not a treatment for DUB.

**Clinical Pearl / High-Yield Fact**
It's essential to differentiate between DUB and other causes of abnormal uterine bleeding, such as polyps, fibroids, or endometrial cancer, as the treatment approach varies significantly.

**Correct Answer:** C.
