Progesterone testing can prove beneficial in determining whether 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 mostly produced in the ovaries and by the placenta following conception.
After the release of an egg from the ovaries, something called a corpus luteum is created inside of the ovary that released the egg that produces progesterone in small amounts. It works to prepare the uterus in case the egg gets fertilized and implants.
When an egg isn’t fertilized, the corpus luteum dissipates, progesterone levels decrease, and menstrual bleeding commences. If the egg does implant, the corpus luteum continues to produce progesterone. Eventually, the placenta assumes its role as the progesterone producer – releasing large amounts of it throughout the remainder of the pregnancy.
Why progesterone testing is important
Testing for progesterone can help women experiencing infertility or trying to track ovulation patterns. It can also help determine the cause of abnormal vaginal bleeding.
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
