Progesterone Testing

Progesterone testing can help you know if your body has enough progesterone hormone in it to start and sustain a pregnancy. It’s a hormone that works with many other female hormones involved in conception and pregnancy.

Where is progesterone made?

Progesterone is primarily made in the ovaries and by the placenta once a child is conceived.

After an ovary releases an egg, something called a corpus luteum is created inside of the ovary where the egg was released from and it produces progesterone in small amounts. This is getting the uterus ready in case the egg gets fertilized and implants.

If the egg doesn’t get fertilized, the corpus luteum goes away, progesterone levels go down and menstrual bleeding begins. 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 rest of the pregnancy.

Why check for progesterone?

Testing for progesterone may help a woman if she’s experiencing infertility or trying to track ovulation patterns. It may also be used to 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
