Sex hormone balance is dependent on all the other hormones in the body. Adrenal and thyroid balance is required before sex hormones will balance. Too much thyroid medication can make adrenals worse. Too much cortisol from stress can stop sex hormones from working well and cause mensal cycles to stop or become irregular.
As men age testosterone is converted to estrogen. When levels are low and testosterone is supplemented increasing estrogen levels will nullify the desired effect of the testosterone. This conversion must be blocked. Erectile dysfunction is more related to the lack of nitric oxide than low testosterone. Balance is the key to all hormonal problems.
