Is it low T is a common question asked by many men when they face dreadful hormone imbalance symptoms or effects of having low testosterone levels. When a man needs the feel to ask himself is it low T, it is important that he gets tested. Getting tested for low testosterone levels is highly important as studies link great health risk factors with low T. T is here represented testosterone. Due to the important role recent studies have shown of optimal testosterone levels, many regular physicians questions is it low T for the many health conditions middle aged man's face these days.
Even diabetes and heart function is related to good testosterone levels. Aging naturally decreases testosterone levels but there are various other factors that also cause low testosterone levels in men. Some of the factors that affect testosterone levels in men include.
DHEA: Dehydroepiandrosterone (DHEA) is a hormone produced from cholesterol which then follows one of two pathways, both involving two-step enzymatic conversions, yielding either estrogens or testosterone. Thus, levels of DHEA can have a role in determining levels of estrogen and testosterone.
Aromatase: One of the most important factors that affect testosterone levels and the ratio between testosterone and estrogen is the aromatase enzyme. Aromatase converts testosterone to estrogen, which further depletes free testosterone levels and increasing estrogen levels.
Obesity: Obesity and associated hyperinsulinemia suppress the action of luteinizing hormone (LH) in the testis, which can significantly reduce circulating testosterone levels. In addition to that, increased belly fat mass has also been correlated with increased aromatase levels further decreasing testosterone levels.
The vicious circle of reduced testosterone and obesity has been called the hypogonadal excessive weight pattern. In this cycle a reduced testosterone level result in boosted stomach fat, which in turn triggers increased aromatase activity. This enhances the conversion of testosterone to estrogens, which further minimizes testosterone and boosts the tendency toward stomach fat.
Sex hormone-binding globulin: Most testosterone which circulates in the bloodstream is bound to either sex hormone-binding globulin (SHBG) which is about 60 percent or albumin about 38 percent, so only a small fraction about 2 percent is unbound, or "free".
Testosterone binds more tightly to SHBG than to albumin hence only albumin bound testosterone and free testosterone constitute the bio available forms of testosterone. Aging men experience both an increase in aromatase activity and an elevation in SHBG production. The net result is an increase in the ratio of estrogen to testosterone and a decrease in total and free testosterone levels.
