Progesterone
Understanding Progesterone
What is Progesterone?
A progesterone test is a blood test that measures its level in the blood. Progesterone plays an important role in pregnancy and fertility. Men also make progesterone but in much smaller amounts.
A progesterone test is used to find the cause of infertility in both men & women, monitor a high-risk pregnancy, find out the days of ovulation, and diagnose an ectopic pregnancy. The levels greater than normal can be indicative of ovarian cancer and cysts apart from pregnancy. If progesterone levels do not rise and fall on a monthly basis, a woman may not be ovulating nor having regular menstrual periods. This may be a cause of infertility.
The progesterone levels keep on fluctuating throughout your pregnancy and menstrual cycle, you may need to be retested several times.
What is Progesterone used for?
- To identify the cause of female infertility by helping track ovulation (release of egg from ovary)
- To help diagnose an ectopic pregnancy (a condition where the fertilized egg is implanted somewhere other than the uterus)
- To monitor the treatment with progesterone hormone
- To monitor the health of the fetus and placenta, especially in high risk pregnancy
- To determine the cause of abnormal bleeding from the uterus
Interpreting Progesterone results
Interpretations
If the result of a single progesterone test falls outside the normal range, it cannot be considered an abnormal result since progesterone levels change continuously. Abnormal results appear if the patient’s blood progesterone levels fall outside the normal range in multiple subsequent tests.
Apart from pregnancy, higher than normal progesterone levels can be seen in cases of:
· Ovarian cysts
· Ovarian cancer
· Molar pregnancy or non-viable pregnancy
· Congenital Adrenal Hyperplasia (CAH)
· Adrenal cancer
Lower than normal progesterone levels can be seen in cases of:
· Amenorrhea or no menstruation
· Anovulation
· Ectopic pregnancy
· Miscarriage or death of fetus
