Guide | Progesterone Testing: How It Helps Assess Female Fertility
Progesterone is a hormone that plays a key role in pregnancy and the menstrual cycle. A progesterone test is a blood test that measures this hormone and can provide important information about female fertility and pregnancy. This article explains the test's uses, procedure, and results.
1. What Is a Progesterone Test?
A progesterone test measures the level of progesterone in the blood. Progesterone is essential in pregnancy: it prepares the body for implantation of a fertilized egg and helps prepare the breasts to produce milk. It also helps regulate the menstrual cycle. Progesterone levels rise around ovulation each month; if pregnancy does not occur, they fall and trigger menstruation.
2. Uses of Progesterone Testing
A doctor may recommend a progesterone test to:
Investigate difficulty becoming pregnant
Determine whether and when ovulation occurs
Assess whether there is a high risk of miscarriage during pregnancy
Monitor a high-risk pregnancy
Diagnose an ectopic pregnancy, in which a fertilized egg implants outside the uterus
Progesterone Test Procedure
The procedure is simple and requires no special preparation. A doctor or other healthcare professional inserts a needle into a vein in your arm and sends a small blood sample to a laboratory.
3. Progesterone Test Results
Results may indicate the following:
Irregular progesterone fluctuations: If repeated testing shows that progesterone does not fluctuate normally each month, you may not be ovulating or may have irregular periods, which can affect the chance of pregnancy.
Low progesterone: This may relate to the phase of the menstrual cycle when the test was performed. Below-normal progesterone may indicate:
Abnormal ovarian function or lack of ovulation
Abnormal pregnancy
High progesterone: Above-normal progesterone may result from:
Pregnancy with one or more fetuses
Ovarian cysts
A tumor causing pregnancy-like symptoms (molar pregnancy)
Adrenal gland disease
Ovarian cancer
Normal progesterone: A result within the normal range may indicate that ovulation has occurred. Testing should be performed 18 to 24 days after menstruation begins or seven days before the next expected period.
4. Other Tests Related to Progesterone
If your doctor recommends progesterone testing, you may also need:
Other blood tests to assess fertility
Home urine tests that indicate ovulation by measuring progesterone metabolites
Ultrasound to measure endometrial thickness
Specific blood tests during pregnancy to assess possible pregnancy complications
