Ovulatory DUB

Introduction Ovulation dysfunctional uterine bleeding mainly occurs in women of childbearing age. The clinical manifestations are regular menstrual cycles, and there is no abnormality in pelvic internal examination. Ovulation dysfunctional uterine bleeding occurs mostly in women of childbearing age, mainly due to follicular dysplasia or hypothalamic pituitary dysfunction, resulting in insufficient luteal function after ovulation, or shortening of the luteal phase, or corpus luteum atrophy. The unsound development of the corpus luteum is mainly due to hypoplasia of the corpus luteum, and the secretion function is not good, so that the amount of progesterone secretion is insufficient. The corpus luteum is well developed, and its function can last for a long time because the corpus luteum fails to shrink in time.

Cause

The cause of ovulatory dysfunctional uterine bleeding:

Examination and diagnosis of ovulatory dysfunctional uterine bleeding:

1. Luteal dysfunction: due to premature luteal phase degeneration, the luteal phase is shortened by less than 10 days. Clinical manifestations of frequent menstruation, shortened cycle, premenstrual bleeding and excessive menstrual flow, often combined with infertility and early abortion. The endometrium of the curettage showed poor secretion, and the secretion reaction lags behind normal for 2 days.

2. The corpus luteum atrophy: the patient has ovulation, the corpus luteum develops well, but the process of atrophy is prolonged, and the clinical manifestation is prolonged menstruation and dripping. In the menstrual period of 5 to 6 days, the endometrium of the menstrual period showed a change in the proliferative phase and the secretory phase, and the basal body temperature in the menstrual period was still high, not falling or falling slowly.

3. Ovulation menstrual disorders: puberty ovarian sensitivity to gonadotropin is enhanced to accelerate follicular development, shortening follicular phase, frequent menstruation. If the patient is premenopausal, both the follicular phase and the luteal phase are shortened or early menopause.

4. Menstrual mid-term hemorrhage: that is, bleeding during ovulation, due to fluctuations in estrogen during ovulation, a small amount of uterine bleeding for 1 to 3 days, no more bleeding, basal body temperature in the ovulation period, increased body temperature, uterine bleeding.

Differential diagnosis

Symptoms of ovulation dysfunctional uterus:

Differential diagnosis:

(1), no ovulation and dysfunctional blood:

1. Medical history: menstrual cycle, irregular menstruation, less or more menstrual blood, or even shock due to more blood loss, common in adolescent or menopausal women, no dysmenorrhea or premenstrual bloating.

2. Check: Adolescent women have slightly worse breast development, slightly smaller uterus, bilateral ovaries may be slightly smaller or slightly larger, B-ultrasound sees follicles, BBT monophasic; menopausal women have normal or slightly larger uterus, no special ovary, before menstruation Diagnostic curettage of the endometrium is proliferative or proliferative. The levels of blood FSH and LH may be slightly lower, blood E2 levels may be lower or normal, and blood T levels may be normal or slightly higher.

(B), there are ovulation dysfunctional blood:

1. History: The menstrual cycle rule is shortened to about 20 days, the menstrual period is normal or lasts for more than 7 days and can reach more than 10 days. Before the menstruation, there may be short-term bloating, less abdominal distension, mild abdominal discomfort during the influx, often infertility or Abortion during early pregnancy.

2. Examination: BBT monitoring, diagnostic curettage and hormone level determination.
