What is progesterone

The ovaries also play an important reproductive role in a woman's body. If there is a problem with the ovaries, it will affect the normal secretion of hormones in a woman's body, thereby affecting the overall endocrine system. Among them, progesterone is an important hormone secreted by the ovaries. Especially for women who are preparing for pregnancy, they will have progesterone tests regularly. Next, we will share some knowledge about progesterone for women.

By testing human luteinizing hormone, we can detect the best time for women to become pregnant, so that families who want children can conceive as soon as possible. We can also detect the reasons why women cannot become pregnant, so that infertile families can find the cause of infertility and provide treatment. In addition, we can also monitor and monitor to ensure that the luteinizing hormone level is not too high or too low, which will cause discomfort to our body.

Therefore, we need to test luteinizing hormone. In the test, we can use an enzyme-linked immunosorbent assay combining monoclonal and polyclonal antibodies to detect the peak secretion period of luteinizing hormone in urine of women of childbearing age to predict the time of ovulation. It is a new method for detecting ovulation. Qualitative determination of the LH peak phase using morning urine to predict ovulation is a non-invasive, economical, convenient and accurate method. Urine LH enzyme-linked immunosorbent assay is an effective method for predicting ovulation that is both accurate and economical, and can be used to treat infertility within 48 hours of a positive result. The urinary LH enzyme-linked immunosorbent assay has the advantages of simple operation, continuous measurement, rapid and sensitive reaction, low price, and can also be used for home self-testing. Magnetic particle separation and enzyme-linked immunosorbent assay can also be used to measure luteinizing hormone in serum.

Observe the linear range, reagent color stability, precision, accuracy and radioimmunoassay pairing comparison. This method has good repeatability, high specificity, accuracy and reliability, good correlation with RIA, and no radioactive contamination, so it is worth recommending. Luteinizing hormone (LH) is a glycoprotein hormone secreted by the pituitary gland. It exists in human blood and urine. Its function is to stimulate the release of mature eggs in the ovaries. LH is secreted rapidly in the middle of the menstrual period, forming an LH peak, which rises rapidly from the basal level to the peak period. The LH in urine usually rises sharply 36-48 hours before ovulation, reaches a peak at 14-28 hours, and about 14-28 hours after the peak, the ovarian membrane ruptures and the mature egg is discharged. LH returns to basal levels two days after ovulation and the luteal phase begins, which usually lasts 14 days. Then new follicles begin to develop and enter the next menstrual cycle, and this cycle repeats until pregnancy occurs. Women are most likely to conceive within 1-3 days after the LH peak.
