Oestrogen (Estrogen) & Andropause

Oestrogen in men is produced from testosterone by aromatisation, an enzymatic conversion mediated by the enzyme aromatase. Oestradiol (estradiol) is the most potent oestrogen.

Excess oestrogen in men can be problematic, but at the right levels oestrogen is important to men’s health. In fact, it is through oestrogen that many of testosterone's actions are mediated. The problems associated with elevated oestrogen levels and the benefits of healthy oestrogen levels in men are listed below.

As men age, an imbalance can develop between testosterone and oestrogens, with oestrogen rising in relative terms. This is the controversial male menopause or 'andropause'.

Oestrone, another oestrogen, is formed primarily by aromatisation of androstenedione. Oestrone is a weaker oestrogen than oestradiol, possessing about 20% of its activity, but is readily converted to oestradiol. In aging or obese men oestrone concentrations can be high, so oestrone's impact can itself be significant.

The concept of balance is paramount, with oestrogen levels maintained within range for optimal function. Measure your oestrogen levels and test for andropause (male menopause) here...
