Diagnosis of anovulatory dysfunctional uterine bleeding

Diagnosis of anovulatory dysfunctional uterine bleeding

Anovulatory functional uterine bleeding is a type of functional uterine bleeding. The specific diagnostic methods are as follows:

1. Monophasic basal body temperature. In the menstrual cycle of normal women, the basal body temperature can be divided into a low temperature phase and a high temperature phase. The low temperature phase starts 1-2 days before the menstruation. In the first half of the menstruation, the basal body temperature fluctuates around 36.5℃ and lasts for about 14 days. It drops slightly during the ovulation period, then rises to enter the high temperature phase, and the body temperature fluctuates around 37℃, maintaining for about 12 days, and drops again 1-2 days before the next menstruation. This is called a biphasic basal body temperature. If there is no ovulation, the basal body temperature has no high temperature phase, which is called a monophasic basal body temperature.

2. Patients with anovulatory dysfunctional uterine bleeding have typical symptoms, including irregular menstrual cycles, sometimes amenorrhea, sometimes continuous bleeding, or heavy bleeding like metrorrhagia, or light bleeding like leakage, alternating between metrorrhagia and leakage.

3. Diagnostic curettage: Pathological examination of the endometrium shows different degrees of proliferative endometrium: such as proliferative stage, hyperplastic stage, excessive hyperplasia, cystic hyperplasia, adenomatous hyperplasia or atypical hyperplasia.

4. Hormone measurement: Estrogen and progesterone measurement can help understand the functional status of the ovaries and whether ovulation occurs.

5. The B-ultrasound examination of the pelvis showed normal results. Although there was follicular development during ovulation monitoring, no dominant follicle was formed and there were no signs of ovulation.

6. The crystals in cervical mucus are fern-shaped crystals without ellipsoids.

7. Gynecological examination showed that the uterus was slightly enlarged and soft, with no organic lesions.
