Treatment with Hormone Replacement Therapy (HRT) in males: Advantages, drawbacks, and additional information
Hormone Replacement Therapy (HRT), often referred to as testosterone replacement therapy (TRT), is a medical treatment that aims to restore hormonal balance within the body, focusing primarily on addressing testosterone imbalances. As men age, their testosterone levels naturally decline, leading to a variety of symptoms such as decreased libido, erectile dysfunction, depression, anemia, loss of muscle or bone mass, loss of body hair, and fatigue [1].
TRT involves the administration of testosterone to compensate for the body's decline in hormone production. The choice of administration method depends on various factors, including transdermal gels and patches, testosterone implants, and testosterone injections [2].
Potential Risks and Side Effects
While TRT can alleviate symptoms of low testosterone, it carries potential risks, particularly in cardiovascular health, prostate safety, fertility, blood clotting, and psychological effects. Common side effects include skin reactions like acne, breast enlargement (gynecomastia), and worsening of sleep apnea [1][2].
Potential serious or long-term risks include cardiovascular issues, such as increased risk of heart attacks, strokes, heart disease, and deaths, especially in older men or during the initial years of therapy. However, some recent studies show mixed results, with certain trials indicating no increased cardiovascular risk in men with hypogonadism who take TRT short- to medium-term [2][3][5].
TRT can stimulate prostate tissue growth, leading to urinary problems and possibly increasing the risk of prostate abnormalities, including benign and malignant growths. This makes it unsafe for men with prostate or breast cancer [1][3].
TRT often reduces sperm count, potentially leading to infertility. Concurrent treatments such as human chorionic gonadotropin (hCG) may help mitigate this effect [1][5].
TRT can raise red blood cell count, increasing the risk of blood clots, deep vein thrombosis, and pulmonary embolism, which are serious conditions requiring immediate attention [2][3][5].
Increased mood swings and aggression have been reported as potential psychological side effects [3].
Changes in cholesterol levels and lipid profiles may occur, which could contribute to cardiovascular risks. Skin irritation at the application site is common with transdermal testosterone forms [5].
Individual Considerations and Monitoring
Given these risks, testosterone therapy should only be undertaken with professional medical guidance, monitoring, and consideration of individual health status to minimize side effects [1][3]. Certain underlying conditions can worsen with TRT, including severe urinary tract problems, uncontrolled heart disease, untreated severe sleep apnea, prostate or breast cancer, and history of stroke [3].
Before undergoing HRT, it is essential to consult a doctor to determine the best course of treatment. A 2022 review suggests that HRT may improve cognitive function and attention span [4]. However, the National Institute on Aging does not recommend using testosterone to treat natural age-related testosterone changes due to potential increased risk of certain health issues [1].
In summary, while TRT can alleviate symptoms of low testosterone, it is crucial to be aware of the potential risks and to consult with a healthcare provider for regular monitoring and to ensure safe management of these risks.
