Progesteron

Progesterone is a steroid hormone that is mainly produced in the ovaries and during pregnancy in the placenta. It plays an important role in the regulation of the menstrual cycle and the maintenance of a pregnancy. The laboratory value measures the progesterone concentration in the blood serum.

A Progesterone test is recommended for: Women with irregular menstrual cycles or missed periods Women who have difficulty getting pregnant Women suspected of having a miscarriage or corpus luteum deficiency Monitoring hormone status during artificial insemination Pregnant women at risk of preterm birth or other complications

The test helps to confirm ovulation, check ovarian function, and identify possible causes of menstrual disorders or infertility. During pregnancy, it is used to monitor the course of pregnancy and detect risks.

A low progesterone level can indicate ovarian weakness, which can lead to problems with implantation of the egg or an increased risk of miscarriage. Symptoms of a low value are: Irregular or absent menstruation Difficulty getting pregnant Spotting during early pregnancy An elevated progesterone level can be caused by pregnancy, hormonal therapy, or rarely by cysts or tumors.

The testing should be carried out in the second half of the menstrual cycle (luteal phase), about 7 days after ovulation (cycle day 21-23). In pregnant women or in case of suspected cycle disorders, the test can be performed at any time.

Progesterone levels fluctuate during the menstrual cycle and are highest in the luteal phase. The testing is often performed together with other hormones (e.g. LH, FSH, estradiol) to obtain a complete picture of the hormonal status. Progesterone plays a role not only in reproduction, but also has an influence on the skin, the brain and the immune system.
