What is TRT (Testosterone Replacement Therapy)?
February 26, 2025

Testosterone Replacement Therapy (TRT), also known as Androgen replacement treatment, is a type of hormone therapy in which supplements or replacements of androgens, typically testosterone, are administered.
Doctors treat guys who exhibit hypogonadism symptoms due to a deficiency in testosterone using testosterone replacement therapy(TRT). The symptoms of low testosterone can be reversed by taking prescription testosterone, which raises levels of this hormone in the blood. Its use may lead to benefits in energy, mood, sexual function, alertness, and general well-being.
The hormone testosterone is mostly produced in the testicles. Testosterone contributes to men’s bone density and distribution of fat, red blood cell production, facial and body hair and muscle build and strength, sexual desire and sperm generation.
Adolescence and the early stages of adulthood are often when testosterone levels peak. Your testosterone levels generally drop with age; from the ages of 30 or 40, they usually drop every year. For males in their later years, it’s critical to diagnose hypogonadism, a disorder that causes low testosterone, as opposed to natural aging.
Hypogonadism occurs when a problem with the testicles or the pituitary gland, which controls testosterone production, disrupts the body’s ability to maintain normal testosterone levels.
Symptoms of Low Testosterone
Low testosterone can have mild as well as obvious symptoms. Testosterone levels naturally decline with age in men, but certain medical conditions can also lead to abnormally low levels. Some common symptoms of low testosterone include:
- Decreased libido and sex desire
- Erectile dysfunction
- Weariness and low energy
- Loss of facial and body hair.
- Inability to focus
- Depression, irritability, and a low sense of well-being
- Low sperm count
- Rise in body fat
Benefits of TRT
The goal of TRT is to get a person’s testosterone levels back to normal. While the person’s blood testosterone levels should improve within a week, it can take longer for their symptoms to subside. It could take four weeks to several months to observe results.
Some of the potential short-term advantages of TRT are:
- Increased libido and sex drive
- Better erectile function
- Increased energy and cognitive function
- Increased vitality, motivation, and confidence throughout the day
- Healthier appetite regulation
- Enhanced sleep quality
Some long-term benefits after several months of TRT are as follows:
- Better bone and joint health
- Enhanced recovery after exercise
- Fuller growth of facial hair
- Increased production of red blood cells
- Enhanced immune function
Types
Patches: Implementing patches is simple. However, patches may need to be placed more than once a day and may cause skin rashes when used.
Gels: Daily skin application of gels is done in this type of TRT. Utilising them is convenient. However, you must exercise caution so that for a few hours after applying it, no one comes into contact with the treated area. It’s now possible to avoid the chance of exposure to other people by using a nasal gel.
Buccal patch: Apply this twice daily to your upper gums. Although these patches are practical, gum disease or discomfort may result from them.
Injections: The interval between injections can range from two to ten weeks. When compared to other therapies, they are reasonably priced. However, injections might not offer consistent advantages. In between doses, your testosterone levels will return to baseline.
Pellets under the skin: Every three to six months, your doctor will put these pellets beneath your skin. Once implanted, they are incredibly convenient, but every dose necessitates a small amount of surgery.
Oral Testosterone: Newer pills like Jatenzo, Tlando, and Kyzatrex deliver testosterone directly into the bloodstream, avoiding liver issues. Taken twice daily with food, they are effective but costly and may require prior treatment failures for insurance coverage.
Monitoring TRT
After treatment starts, your doctor will check your testosterone levels three and six months later. Subsequently, you will undergo testing annually. If everything checks out, you’ll continue taking your existing dosage.
You might need to change your dosage if your testosterone levels are too low. Your red blood cell counts will be checked concurrently by your physician. If you had osteoporosis before starting therapy, your doctor will take a bone density test one to two years after starting TRT. Prior to initiating treatment, your doctor will assess your likelihood of developing prostate cancer. He or she may then repeat tests after three and six months, and then once a year.
Side Effects
The use of testosterone therapy entails certain risks due to the strong hormones involved. Some of the common disadvantages are as follows:
Testosterone Therapy Hazards: The use of testosterone therapy entails certain risks due to the strong hormones involved. Certain are uncommon, while others are common. Anybody receiving therapy should be informed of the potentially life-altering adverse effects, even though not all of them are serious.
Following TRT, common hazards include:
- Research suggests that testosterone therapy can worsen sleep apnea, a disorder characterized by temporary pauses in breathing during sleep.
- Many men who start a testosterone cycle also get severe acne and skin outbreaks. Anti-inflammatory drugs or dosage adjustments can be used to treat these side effects.
- Inflammation of the prostate gland, Benign prostatic hyperplasia (BPH; non-cancerous tumor of the prostate)
- Prostate tumor growth acceleration
- Gynecomastia (widening breasts)
- Reduced proliferative capacity, testicular shrinkage, and heightened susceptibility to blood clots that could result in a potentially fatal pulmonary embolism
- Congestive heart failure
How to Increase Testosterone Naturally
Enhancing testosterone levels naturally involves adopting healthy lifestyle habits, optimizing nutrition, and managing stress effectively.
1. Engage in Strength Training and High-Intensity Exercise
Consistently participating in strength training and high-intensity interval exercises (HIIT) can play a crucial role in naturally increasing testosterone levels. Weightlifting and other resistance exercises promote muscle growth, which triggers the body to enhance testosterone production. Additionally, short bursts of intense workouts can elevate hormone levels more effectively than steady-state cardio exercises.
2. Prioritize a Testosterone-Boosting Diet
Your dietary choices significantly influence hormone regulation. You may benefit from incorporating:
- Protein-rich foods (lean meats, eggs, fish) are needed to maintain muscle mass and support hormonal balance.
- Healthy fats (avocados, nuts, olive oil) are essential for testosterone synthesis.
- Complex carbohydrates (quinoa, brown rice, vegetables) to provide sustained energy and prevent hormonal disruptions.
3. Improve Sleep Quality
Testosterone production is closely linked to sleep cycles. During deep sleep, the body produces the highest amounts of testosterone. Strive for 7 – 9 hours of continuous sleep each night to maintain optimal hormone balance. Poor sleep can reduce testosterone by up to 15% in just a few days.
4. Manage Stress and Lower Cortisol Levels
Persistent stress elevates cortisol levels, which can interfere with testosterone production. To keep stress in check:
- Include relaxation methods like deep breathing and meditation to enhance mindfulness.
- Participate in calming activities like practicing yoga or enjoying nature outdoors.
- Maintain a balanced work-life routine to prevent long-term stress buildup.
5. Get Sufficient Vitamin D and Zinc
- Vitamin D: This essential nutrient plays a direct role in testosterone production. Exposure to sunlight or taking vitamin D3 supplements can help maintain adequate levels.
- Zinc: Found in oysters, nuts, and seeds, zinc is crucial for testosterone synthesis. Low zinc levels can contribute to reduced hormone production.
6. Avoid Endocrine Disruptors
Certain chemicals, like bisphenol A (BPA) found in plastics and processed food packaging, can mimic estrogen in the body and lower testosterone levels. To minimize exposure:
- Use glass or stainless-steel containers for food storage.
- Avoid microwaving food in plastic.
- Opt for fresh, whole foods instead of canned or heavily processed meals.
7. Limit Alcohol and Sugar Consumption
Excessive alcohol and high sugar intake can disrupt testosterone production and lead to weight gain, further worsening hormonal imbalances. Reducing alcohol intake and avoiding processed sugars can help maintain healthy testosterone levels.
8. Maintain a Healthy Weight
Carrying excess weight, particularly around the midsection, can lead to a decline in testosterone levels while increasing estrogen production. Consistent physical activity and a nutritious diet support a healthy body composition, which aids in maintaining hormonal balance.
9. Consume Natural Testosterone-Boosting Foods
Incorporating natural testosterone-enhancing foods into your diet can have a significant impact:
- Onions and garlic: Boost testosterone production and improve blood circulation.
- Pomegranates: Known to reduce stress hormones and support testosterone levels.
- Leafy greens (spinach, kale, Swiss chard): High in magnesium, which helps in testosterone synthesis.
- Ginger: Traditionally used for its medicinal properties, ginger has been shown to improve testosterone levels in some studies.
When Should I See a Doctor?
TRT users should speak with the doctor if they observe any of the following symptoms:
- Weakness on one side of the body
- A choking sensation in the chest
- Breathing difficulties or shortness of breath
- Difficulty speaking.
Conclusion
While TRT is a widely used treatment for low testosterone, it may not be the right option for everyone. Individuals who are thinking about TRT require a prescription and suitable advice from a physician or other licensed healthcare provider.
