What are the symptoms of corpus luteum insufficiency?

The corpus luteum refers to progesterone, which is a natural progesterone secreted by the female ovaries. If the corpus luteum is insufficient, it often leads to difficulty in conception, ovulation bleeding, or poor implantation of the fertilized egg after conception, causing threatened abortion. Luteal insufficiency is the main factor of female infertility and has a great impact on women's physical and mental health. Understanding the symptoms of luteal insufficiency will help with targeted treatment.

1. Symptoms of luteal insufficiency

Luteal insufficiency refers to the insufficient endocrine function of the luteum formed after ovarian ovulation, resulting in insufficient secretion of progesterone, insufficient secretion and transformation of the endometrium, and ovulatory dysfunctional uterine bleeding.

The main symptoms of patients with luteal insufficiency are as follows:

1. Menstrual disorders: Patients with luteal insufficiency will experience shortened menstrual cycles (less than 28 days), increased frequency of menstruation, and heavy premenstrual bleeding.

2. Infertility: Women in their childbearing period will find it more difficult to conceive, or they may easily suffer miscarriage if they become pregnant.

3. The endometrium cannot produce normal secretory response, and the endometrial response is unbalanced.

4. Basal body temperature: The day after a woman ovulates, the corpus luteum is formed in the ovaries. The secretion of progesterone by the corpus luteum will cause the body temperature to rise by about 0.6 degrees Celsius, causing the body temperature to fluctuate between high and low phases. The high temperature period lasts about 14 days. However, patients with luteal insufficiency will experience a slower rise in body temperature, or a lower increase, usually less than 0.5°C.

2. The clinical manifestations of corpus luteum insufficiency are:

1. The menstrual cycle is normal, but the period is prolonged, which can be up to 9-10 days or even longer, but the amount is not too much. That is, 2-3 days after the menstruation is over, the vagina will drip again.

2. Secretion of brown secretions. During the days when there is this kind of vaginal secretion, there will be a dull pain in the lower left abdomen, as if there is air that is not flowing and is blocked there.

3. Some women may experience ovulation bleeding (a small amount of bleeding between two menstrual periods) and lower abdominal pain.

4. The basal body temperature is biphasic but decreases slowly, and often has not dropped to the normal proliferation level during the menstrual period (the body temperature during the menstrual period is still in the high temperature period).
