Description

The Progesterone Blood Test measures the level of progesterone, a key sex hormone involved in menstrual regulation, fertility, pregnancy support, and overall hormonal health. While progesterone is most commonly associated with female reproductive function, it is also produced in men and plays an important role in testosterone balance and mood regulation.

Progesterone testing is helpful for evaluating ovulation, diagnosing hormone-related symptoms, and monitoring pregnancy or hormone therapy.

Purpose of the Test

  • Evaluate ovulation and menstrual cycle timing
  • Investigate infertility or irregular cycles
  • Support early pregnancy monitoring
  • Assess hormonal symptoms such as mood swings, insomnia, or low libido
  • Monitor hormone replacement therapy
  • Assist in understanding sex hormone balance in both women and men

Who Should Consider This Test?

In Women:

  • Trying to conceive or undergoing fertility treatment
  • Suspecting anovulation or luteal phase issues
  • Experiencing symptoms of hormonal imbalance (PMS, fatigue, anxiety, short luteal phase)
  • Monitoring early pregnancy with progesterone supplementation

In Men:

  • Evaluating testosterone and estrogen balance
  • Experiencing low libido, fatigue, or mood symptoms
  • Monitoring hormone therapy or adrenal health

What the Test Measures

  • Progesterone (Serum Level)
  • Progesterone levels rise after ovulation in women and are essential for preparing the uterine lining for implantation. In men, progesterone helps balance estrogen and supports testosterone metabolism.

Common Conditions Associated with Abnormal Progesterone Levels

  • Low Progesterone (Women): Anovulation, luteal phase defect, infertility, early miscarriage, PMS
  • Low Progesterone (Men): Estrogen dominance, low testosterone symptoms, mood instability
  • High Progesterone: Pregnancy, ovulation phase, hormone therapy, adrenal conditions
