Testosterone Replacement Therapy TRT: What to Know

Testosterone Replacement Therapy TRT: What to Know

Some men may have levels below 300 ng/dL and no symptoms, so screening all men for low testosterone is a bad idea, says the Endocrine Society’s guidelines. In one analysis of 13 studies of roughly 4,300 men with obesity, 43 percent had blood levels of testosterone under 300 ng/dL. After you’ve been on TRT for about two months, your doctor will evaluate your symptoms. If there’s no noticeable improvement, the dosage may be increased, continued at its current amount for a bit longer, or stopped. Dr. O’Leary says your doctor might recommend TRT if your levels drop below 300 ng/dL, but it’s not automatic. “The first step is to determine if any symptoms attributed to low testosterone are related to something else that’s treatable.” If you’re a good candidate for TRT, we have several delivery forms, including injections, gels, patches, pellets, and nasal spray.

Testosterone enanthate (available generically) injection may be used in certain women with a type of breast cancer called mammary cancer that has spread to other parts of the body. Testosterone should not be used to treat the symptoms of low testosterone in men who have low testosterone due to aging (‘age related hypogonadism’). Testosterone is in a class of medications called androgenic hormones. Testosterone is a hormone produced by the body that contributes to the growth, development, and functioning of the male sexual organs and typical male characteristics. Testosterone injection works by supplying synthetic testosterone to replace the testosterone that is normally produced naturally in the body. When used to treat breast cancer, testosterone works by stopping the release of estrogen. Sex drive (sexual desire) is a complex aspect of sexual function and is difficult to objectively measure.

Clinicians wishing to identify laboratories meeting CDC standards are encouraged to refer to the list of sites currently meeting CDC requirements listed on the CDC Hormone Standardization Program. No randomized controlled trial has demonstrated decreased cardiovascular events or mortality with testosterone therapy. Because of circadian variations in testosterone levels, serum testosterone measurement should occur in the morning, or within two hours of awakening in shift workers (Figure 19 ). Although there is no universal laboratory definition of hypogonadism, in most laboratory reference ranges, the lower limit of normal is between 250 and 350 ng per dL (8.7 to 12.2 nmol per L). Based in part on available evidence from published studies, the U.S.

If you wonder whether testosterone therapy might be right for you, talk with your doctor about the risks and benefits. Most prostate cancers eventually stop responding to hormone therapy and become castration (or castrate) resistant. That is, they continue to grow even when androgen levels in the body are extremely low or undetectable.

Around age 30, a man’s testosterone levels may slowly begin to decline. Approximately 35% of men in their 70s have low-T, according to the American Urological Association. In 2015, the FDA announced that it would require drugmakers to issue a new warning label surrounding testosterone and cardiovascular safety. The agency cited certain studies that found testosterone therapy increased the risk of heart attack and stroke. The Food and Drug Administration (FDA) explains that the benefits and safety of TRT for treating low testosterone levels due to aging are not known. The organization requires that testosterone products carry warnings mentioning the possible risk of stroke and heart disease.

They have improved in many of the outcomes measured in the TTrials when treated with testosterone, he says. But the drug didn’t improve energy, walking distance, or cognitive function in men girls with high testosterone age-related memory loss, and it increased the amount of non-calcified plaque in blood vessels supplying the heart. None of the men in the testosterone group or the placebo group were reported to have a major cardiovascular event.

Several clinical trials are examining whether exercise can reverse or prevent side effects of hormone therapy for prostate cancer. Researchers have investigated whether a technique called intermittent androgen deprivation can delay the development of hormone resistance. With intermittent androgen deprivation, hormone therapy is given in cycles with breaks between drug administrations rather than continuously, particularly in people with a biochemical recurrence. The goal of intermittent androgen deprivation is to delay the development of hormone resistance.

Doctors cannot predict how long hormone therapy will be effective in suppressing the growth of any individual man’s prostate cancer. Therefore, men who take hormone therapy for more than a few months are regularly tested to determine the level of PSA in their blood. An increase in PSA level may indicate that a man’s cancer has started growing again or become resistant to the hormone therapy that is currently being used. Prior to starting testosterone therapy, men should check with a provider to confirm the treatment is the right fit. If you’re on any sort hormone management like testosterone therapy, it’s important to maintain regular follow up care. The hormones can keep you feeling really good for a really long time, but it’s important to keep tabs on how they’re affecting your body with a professional. After first starting testosterone therapy, your doctor may insist on frequent visits and tests to track your treatment and adjust medication as needed.

There is no utility in continuing testosterone therapy in men who achieve target testosterone levels without symptom improvement. An exception can be made if patients do not have symptoms but have documented BMD loss. In this clinical scenario, an argument can be made to continue testosterone therapy.
