Alternatives to Hormone Replacement Therapy for Men: The Role of Testosterone/Estrogen Balance

Reports indicate that 20% of men over 60 years of age are deficient in testosterone. This number rapidly increases to more than 50% of all men over the age of 80.

The declining levels of testosterone are a natural occurrence for a number of physiological reasons. But their effects are not salubrious. The corollaries are coronary disease and a lack of physical and emotional well-being.

While testosterone replacement therapy got most of the attention in an attempt to restore male hormonal balance. Now estrogen is gaining a spotlight on the research scene.

Although estrogen has been a hormone associated with women, its role in men’s health has been increasingly noted. Among men with chronic heart failure, for example, both high and low concentrations of estradiol were related to increased mortality. The subjects in the middle quintile of estradiol concentrations had the best survival rate.

This powerfully illustrates the importance of keeping estrogen levels in balance.

Restoring testosterone levels to youthful ranges can result in an increase in insulin sensitivity. Plus a host of health benefits such as: reductions in total cholesterol, fat mass, waist circumference and pro-inflammatory cytokines. Said cytokines commonly associate with atherosclerosis, diabetes, and metabolic syndrome.

Testosterone replacement therapy also appears to improve metabolism and endurance in patients with heart disease. It even helps lower depression in older men.

Testosterone therapy improves men’s health – no questions here.

Therefore, rather than focusing solely on replenishing the lost testosterone in men, it is critical to take a closer look at the role of estrogen. Since estrogen meddles with male hormonal balance. And ultimately contributes to “testosterone deficiency.”

Let’s look at a few reasons why testosterone declines with age

DHEA: This hormone can follow pathways that either yields testosterone or estrogen. Consequently it can play a role in determining levels of estrogen and testosterone. This hormone declines in older men, compromising their ability to produce testosterone.

Aromatase: This enzyme is critical because it converts testosterone to estrogen. As men age, their levels of aromatase increase, thereby depleting free testosterone and increasing estrogen levels.

Obesity: Hyperinsulinemia suppresses the action of the luteinizing hormone (LH), which can reduce circulating testosterone levels

Increased belly fat mass has also been linked to increased aromatase levels, which precipitates a vicious cycle of abdominal fat exacerbating the increased aromatase activity. This cycle further reduces testosterone levels. This circular relationship between fat and estrogen production is the proverbial amusement park ride off of which we need to jump to start correcting this hormonal imbalance.

Sex hormone-binding globulin (SHBG): Levels of SHBG also increase with age, which makes the bioavailability of testosterone circulating in the bloodstream lower. The increase in SHBG coupled with an increase in aromatase activity results in a net increase in the estrogen to testosterone ratio. And consequently a decrease in total and free testosterone levels.

Liver: Finally, the liver plays an important role in removing excess estrogen and SHBG. So it is crucial for aging men to maintain optimal liver function for hormonal balance.

Testosterone vs. Estrogen

Closely related, testosterone and estrogen, yet display vastly different effects in the body. Testosterone improves muscle mass and bone density and can have a positive effect on the heart, brain and blood vessels. While higher levels of estrogen put men at greater risk for chronic illness. Estrogen is made by fat cells. Hence the first target of influence in lowering estrogen levels should be lifestyle modifications. Exercise and weight loss yield particularly good results by increasing insulin sensitivity and lowering body fat.

Eurycoma longifolia, a medicinal plant commonly called tongkat ali (TA), is a natural alternative to TRT. It helps restore serum testosterone levels. This includes significant positive effects on bone health and the overall physical condition of patients. In addition, it demonstrates a significant antihyperglycemic effect and cytotoxicity against prostate cancer. Thus far, at therapeutic concentrations, no significant side effects of the treatment with TA were obvious. Therefore, it might be a safe alternative to testosterone replacement therapy. TA also enhances testosterone steroidogenesis in the Leydig cells by inhibiting aromatase conversion of testosterone to estrogen.
