What is the cause of luteal phase discharge?

The period after a woman's ovulation and before her menstrual period is called her luteal phase, during which progesterone, estrogen and relaxin are secreted. If a woman who is trying to get pregnant has less secretions during the luteal phase, this will result in too little progesterone, making it difficult for her to get pregnant. The corpus luteum is very important to women and is related to female infertility issues. So, when exactly is the luteal phase?

When is the luteal phase

According to experts, the main function of the corpus luteum is to secrete progesterone, estrogen and relaxin. However, not everyone knows when the luteal phase of women is.

In women with luteal insufficiency, progesterone secretion is mostly insufficient. Progesterone mainly acts on the endometrium, causing secretory changes in the uterus, which is very necessary for the implantation of the fertilized egg and the maintenance of pregnancy. If progesterone is not secreted sufficiently, the secretory changes of the endometrium will be adversely affected.

What is the female luteal phase? In clinical practice, endometrial biopsy often finds that some infertile women have poor secretory function, which is not conducive to the implantation of the fertilized egg. Even if the fertilized egg implants, miscarriage may occur due to insufficient progesterone secretion. According to statistics, 3-4% of infertile women are caused by luteal insufficiency.

Generally speaking, the female luteal phase refers to the 15th to 29th day of the menstrual cycle. The ovulatory follicle forms a corpus luteum and secretes a large amount of progesterone and estrogen. Progesterone reaches its peak on the 22nd to 23rd day. At this time, it is most reliable to measure the progesterone level and evaluate the corpus luteum function. The endometrium continues to thicken and reaches 15-19mm before menstruation.

At the end of the luteal phase of a woman's life, the growth of the endometrium reaches its peak, preparing the conditions for the implantation and continued development of the fertilized egg.

The gynecologist explained that under normal circumstances, after ovulation, the follicle will luteinize, form a corpus luteum and secrete estrogen and progesterone to stimulate the growth of the endometrium. However, if neuroendocrine regulation dysfunction or other reasons lead to insufficient progesterone secretion during the luteal phase or premature luteal recession, it will lead to endometrial hypoplasia and shortened luteal phase, causing female infertility.

The above is the specific inference method about the luteal phase. The luteal phase is roughly between the 15th and 29th day of the menstrual cycle. After the ovulation period, the luteal phase begins, when progesterone and estrogen are secreted. If some female friends have luteal deficiency, they should go to the hospital for examination and treatment in time to avoid infertility.
