Understanding Testosterone and Andropause
Introduction
Testosterone, often referred to as the “male hormone,” is a crucial player in human health. While it’s predominantly associated with men, testosterone also plays an important role in women, albeit at lower levels. This hormone is responsible for regulating a wide range of bodily functions, including muscle mass and mood regulation. However, as men age, testosterone levels naturally decline approximately 1 to 2% per year, leading to a condition known as andropause.
What is Testosterone?
Testosterone is an androgen hormone primarily produced in the testes in men and, to a lesser extent, in the ovaries and adrenal glands in women. In men, testosterone levels peak during adolescence and early adulthood, playing a pivotal role in the development of male secondary sexual characteristics such as facial hair, a deeper voice, and increased muscle mass.
Beyond puberty, testosterone continues to regulate essential functions like maintaining bone density, muscle strength, and red blood cell production. It also influences mood, energy levels, and libido, making it integral to overall wellbeing.
What is Andropause?
Andropause, sometimes referred to as ‘male menopause,’ or by some GP’s I know, as ‘Man-opause’ describes the gradual decline of testosterone levels in men, typically beginning in their late 30s or early 40s (but in my experience this can vary significantly man to man and many guys I know if there 40’s have seen a much more dramatic drop). Unlike the abrupt hormonal changes seen in menopause for women, andropause is generally more gradual and often subtle, making it harder to identify.
Symptoms of Andropause:
- Fatigue and low energy levels.
- Decreased libido and erectile difficulties.
- Loss of muscle mass and increased body fat.
- Mood changes, such as irritability or mild depression.
- Difficulty concentrating or “brain fog.”
Causes of Testosterone Decline
While ageing is the primary cause of declining testosterone levels, other factors can accelerate this process. Lifestyle habits such as poor diet, lack of exercise, chronic stress, and inadequate sleep can contribute to lower testosterone. Additionally, certain health conditions like obesity, diabetes, and metabolic syndrome are linked to reduced testosterone levels.
Addressing andropause isn’t just about restoring hormone levels – it’s about improving overall health and wellbeing. By recognising the signs early, men can take proactive steps to manage symptoms and optimise their health.
Part 2 of our series next week will explore the physical effects of reduced testosterone and some effective lifestyle interventions.
