Progesterone is a hormone that your body produces. Both men and women produce it. But it’s mainly produced in the ovaries, which means women tend to have more of it.
A progesterone test can help your doctor check on ovulation or possible fertility problems, make sure everything is OK if you’re already pregnant, or help find out why you have abnormal bleeding from your uterus.
Normal test results: 1) men, postmenopausal women, and women at the beginning of their menstrual cycle: 1 ng/mL or under
2) women in the middle of their menstrual cycle: 5 to 20 ng/mL
3) pregnant women in their first trimester: 11.2 to 90 ng/mL
4) pregnant women in their second trimester: 25.6 to 89.4 ng/mL
5) pregnant women in their third trimester: 48.4 to 42.5 ng/mL
