What is progesterone?

Progesterone is a crucial hormone in the female body, primarily produced by the ovaries after ovulation and in smaller amounts by the adrenal glands. It plays an essential role in regulating the menstrual cycle, supporting early pregnancy, and influencing libido. Progesterone also helps prepare the uterine lining for the implantation of a fertilized egg.

Why test progesterone?

Testing progesterone is useful for women experiencing problems with their menstrual cycle, such as irregularities or absence of menstruation, or those having difficulty becoming pregnant. It can also be used to assess the health of a pregnancy, particularly in cases of suspected miscarriage or ectopic pregnancy. Additionally, it can be helpful in evaluating symptoms related to hormonal imbalance, such as PMS or menopausal symptoms.

What does it indicate?

Progesterone levels provide insight into a woman's ovulatory and menstrual health. Normal levels can vary depending on the menstrual cycle phase or pregnancy status. It helps in diagnosing conditions such as ovulation disorders, luteal phase defect, and can contribute to understanding infertility issues.

What does a high progesterone level mean?

A high level of progesterone is common during the second half of the menstrual cycle and throughout pregnancy. Outside these periods, a high level may indicate ovarian cysts, molar pregnancy, or overproduction by the adrenal glands.

What does a low progesterone level mean?

A low progesterone level may indicate a lack of ovulation, a problem with the ovaries or adrenal glands, or a risk of miscarriage if the woman is pregnant. It can also worsen symptoms of PMS and menopause.
