Testosterone is a steroid hormone and is made from cholesterol in the testes for men and ovaries for women. Small amounts are made in the adrenal glands.

The pituitary gland in the brain releases a hormone called luteinizing hormone which acts as a messenger to tell the testes to start making testosterone.

When we talk about hormone imbalance we often think about female imbalances, but it is important to understand that male hormone imbalances are becoming more and more frequent, with the most common being low testosterone, often seen with raised levels of oestrogen.

Low testosterone symptoms include:

  • Decreased libido
  • Erectile dysfunction
  • Fatigue
  • Sleep disturbances
  • Depression

Raised oestrogen symptoms include:

  • Excess fat – especially around the breast area, hips and stomach
  • Low libido
  • Increased risk of heart disease
  • Fatigue
  • Infertility

Causes of Male Hormone Imbalances include continuous stress, lack of sleep, environmental oestrogens from pollutants, plastics and household chemicals, Type 2 diabetes, obesity.

How to Increase Testosterone Production:

  • Weight Loss
  • Exercise
  • Nutritional Support
  • Sleep
  • Stress Management
