Progesterone testing can help you determine if your body is producing enough progesterone hormone to sustain a pregnancy. It works with many other female hormones involved in conception and pregnancy.
Where is progesterone produced?
Progesterone is primarily produced in the ovaries and by the placenta following conception.
Following the release of an egg from the ovaries, something called a corpus luteum is created inside of the ovary where the egg was released from. It produces progesterone in small amounts. This is preparing the uterus in case the egg gets fertilized and implants.
If the egg isn’t fertilized, the corpus luteum dissipates, progesterone levels go down, and menstrual bleeding commences. If the egg is implanted, the corpus luteum continues to produce progesterone. Eventually, the placenta takes its role as the progesterone producer – releasing large amounts of it throughout the remainder of the pregnancy.
Why test progesterone?
Testing for progesterone can help a woman if she’s experiencing infertility or trying to track ovulation patterns. It can also help determine why a female’s abnormal bleeding is occuring.
The progesterone lab test will:
- determine if there’s a functioning corpus luteum or luteal cell function
- confirm basal body temperature measurements for the occurrence of ovulation
- obtain an indication of the day of ovulation
