Clinical manifestations of ovulatory dysfunctional uterine bleeding

Many people may not be very familiar with ovulatory functional uterine bleeding. In fact, during the ovulation period, there will be slight bleeding in the uterus. However, the amount of bleeding is generally not too large. If it is too large, you can only seek treatment, which means that there is something abnormal in your body. Some patients have this problem because of luteal insufficiency, which is also a very common cause of the disease.

There is a regular menstrual cycle, but the cycle is shortened, or there is a small amount of bleeding a few days before the period, and the amount of menstrual blood may not change.

It mostly occurs in women of childbearing age, mostly during the recovery period after childbirth or miscarriage. Generally speaking, the gonad axis of women of childbearing age should be in a stable state. Abnormal uterine bleeding is mostly caused by organic diseases, such as inflammation, fat, uterine fibroids, endometriosis, etc., and you should go to the hospital for examination and diagnosis in time. It also sometimes occurs during menopause. It can be divided into two types: corpus luteum insufficiency and corpus luteum atrophy.

1. Luteal insufficiency

Due to insufficient estrogen secretion before ovulation, the corpus luteum may become poorly developed and atrophy prematurely. When the corpus luteum is incompletely developed, its secretory function is poor, resulting in insufficient progesterone secretion. The clinical manifestations are regular menstrual cycles, but the cycles are shortened, or there is a small amount of bleeding a few days before the menstrual period, and the amount of menstrual blood may not change. Premenstrual endometrial biopsy may reveal poor or uneven glandular secretion. Interstitial edema was not obvious. The basal body temperature is biphasic, but rises slowly, and the luteal phase is shorter than normal, generally around 10 days. Due to insufficient gestational period, infertility or early miscarriage often occurs.

2. Corpus luteum atrophy

The corpus luteum is usually well developed, but its function may last too long because it fails to fully atrophy in time. The amount of progesterone secreted is insufficient, but the secretion time is prolonged. At this time, the endometrium sheds irregularly, the bleeding time is prolonged, and the amount of menstrual blood increases, but the menstrual interval is still mostly normal. The amount of blood is high on the 2nd and 3rd days of the menstrual period, and there may be continuous bleeding for more than ten days afterwards. If the endometrium is taken on the 5th or 6th day of menstruation and secretory reaction is still found, it can be one of the bases for diagnosis. The basal body temperature is biphasic, often rising slowly after ovulation, with a low increase and a short duration after the increase, before slowly falling.
