Progesterone testing is primarily used to detect which condition?

Progesterone testing plays a critical role in evaluating conditions related to the female reproductive system, particularly concerning pregnancy and infertility. In women, progesterone is a hormone produced by the ovaries after ovulation. Its primary function is to prepare the endometrium for a potential implantation of a fertilized egg and to maintain pregnancy. Therefore, measuring progesterone levels can help determine if ovulation has occurred and assess the health of the pregnancy.

In cases of suspected infertility, progesterone testing can help ascertain whether a woman has adequate ovulation and hormone levels to support pregnancy. It is also used to monitor pregnancies, particularly in those who may be at risk for complications such as miscarriage. Thus, progesterone testing is essential for understanding reproductive health and diagnosing conditions related to pregnancy and infertility.
