Progesterone

Overview

Progesterone plays pivotal roles across both genders. In women, it’s central to regulating the menstrual cycle, supporting pregnancy by maintaining the uterine lining, and influencing mood and bone health. It’s vital for embryo implantation and the survival of the fetus. In men, progesterone helps to regulate the production of testosterone and is involved in the development of sperm, making it important for male fertility. Additionally, it acts on the central nervous system and supports adrenal health, which impacts a wide array of bodily functions including stress response and immune regulation.

Testing Levels:

• High (6.6 nmol/L) - Elevated progesterone typically indicates pregnancy in women. Outside of pregnancy, high levels can suggest ovarian cysts or adrenal disorders. In men, unusually high levels might indicate an adrenal gland disorder, affecting overall hormonal regulation and potentially leading to symptoms like fatigue and mood swings.
  
  
• Mid - Normal levels indicate healthy reproductive and adrenal function. In women, it means regular menstrual cycles and proper support for pregnancy. In men, it reflects good hormonal health, important for sperm production and overall vitality.
  
  Progesterone levels near the upper limit can suggest a minor hormonal imbalance in both men and women, which might not be cause for immediate concern but should be monitored to prevent potential health impacts.
  
  Slightly low progesterone levels may lead to symptoms like irregular menstrual cycles in women and reduced libido in men. These levels should be monitored to ensure they do not fall further, which could exacerbate health issues.
  
  
• Low (0 nmol/L) - Low progesterone can result in fertility issues and menstrual irregularities in women, and impact sperm quality and hormonal balance in men. It often requires hormonal management or further investigation to identify and treat underlying causes.

Why We Test Progesterone

Measuring progesterone is crucial for anyone experiencing issues with menstrual cycles, trying to conceive, or assessing pregnancy viability in women. For men, testing progesterone can help diagnose adrenal disorders and assess overall hormonal balance, particularly in relation to testosterone levels and sperm production. Abnormal levels can indicate potential health issues requiring targeted interventions, ranging from hormonal therapies to lifestyle changes.

What Affects It

Factors influencing progesterone levels include stress, medication (like contraceptives or hormone therapy), underlying health conditions (like PCOS, adrenal disorders), and lifestyle choices such as diet and exercise. Estrogen and progesterone supplements may affect the results.

How to Improve

Managing progesterone involves dietary adjustments, stress reduction, and regular exercise. Hormone therapy may be necessary for significantly abnormal levels. In cases of high progesterone, identifying and treating underlying conditions such as adrenal disorders is crucial.
