Testosterone is a hormone primarily produced in the testes in males and in smaller amounts in the ovaries and adrenal glands in females.
It belongs to a class of hormones called androgens and plays a crucial role in the development and maintenance of various physiological processes in both sexes.
In males, testosterone is responsible for the development of primary and secondary sexual characteristics during puberty, such as deepening of the voice, growth of facial and body hair, and muscle mass development.
It also influences libido, bone density, and red blood cell production. Testosterone is vital for maintaining overall well-being, mood stability, cognitive function, and energy levels in men.
Females also produce testosterone, albeit in lower amounts. It contributes to female sexual health, including maintaining libido and bone density, and plays a role in overall vitality and well-being.
Testosterone levels naturally decline with age, leading to a condition called hypogonadism. In addition to aging, other factors like certain medical conditions, hormonal disorders, or surgical interventions may result in low testosterone levels.
In such cases, testosterone therapy may be prescribed to restore hormone balance and alleviate symptoms associated with testosterone deficiency.
Types of Testosterone Therapy
Test Injections
Testosterone injections are a widely used form of testosterone therapy for individuals with low testosterone levels. In this method, testosterone is administered through intramuscular injections into the gluteal (buttocks) muscle. Here are some key points to know about testosterone injections:
Administration: Testosterone injections are typically administered by a healthcare professional or self-administered under medical supervision. The injections are given at regular intervals, which can vary depending on the specific treatment plan and individual needs.
Types of Injectable Testosterone: There are different formulations of injectable testosterone available, including testosterone cypionate and testosterone enanthate. These forms of testosterone have longer half-lives, meaning they remain active in the body for an extended period, allowing for less frequent injections.
Dosage: The dosage of testosterone injections varies depending on individual needs and the severity of testosterone deficiency. The healthcare provider will determine the appropriate dosage based on factors such as age, overall health, and response to treatment. Dosages may be adjusted over time to achieve optimal hormone levels.
Absorption and Blood Levels: After the injection, testosterone is slowly released into the bloodstream over time. Blood levels of testosterone rise after each injection and gradually decline until the next injection is due. Regular blood tests are conducted to monitor testosterone levels and ensure they remain within the desired therapeutic range.
Topical Test Application
Topical testosterone refers to the application of testosterone medication in the form of gels, creams, or patches directly onto the skin. Here are some important points to know about topical testosterone therapy:
Application: Topical testosterone is typically applied to clean, dry skin on specific areas of the body, such as the shoulders, upper arms, or abdomen. The exact application site may vary depending on the specific product and instructions provided by the healthcare professional.
Absorption: Once applied to the skin, topical testosterone is absorbed through the skin and enters the bloodstream. It provides a sustained release of testosterone over a period of time.
Types of Topical Testosterone: There are various forms of topical testosterone available, including gels, creams, and patches. Each has its own characteristics and application methods.
a. Testosterone Gel: Testosterone gel is a common form of topical testosterone. It usually comes in single-use packets or a pump bottle. After application, the gel dries on the skin and is absorbed gradually.
b. Testosterone Cream: Testosterone cream is another option, and it is applied similarly to the gel. It is important to follow the specific instructions provided with the cream regarding application frequency and amount.
c. Testosterone Patch: Testosterone patches are applied directly to the skin and deliver a controlled amount of testosterone throughout the day. The patches are usually replaced daily or every few days, depending on the product.
Dosage: The dosage of topical testosterone is prescribed based on individual needs and hormone levels. It is important to strictly follow the recommended dosage provided by the healthcare professional to ensure optimal hormone balance.
Oral Test Supplementation
Oral testosterone, also known as testosterone pills or tablets, is a form of testosterone therapy that involves taking testosterone orally. While oral testosterone is available, it is not commonly used as a primary treatment option for low testosterone levels due to some limitations and potential risks. Here are some important points to know about oral testosterone:
Administration: Oral testosterone is taken in the form of pills or tablets that are swallowed with water. The frequency and dosage will be determined by the healthcare professional based on the individual’s needs and hormone levels.
Limited Availability: Oral testosterone is less commonly prescribed compared to other forms of testosterone therapy. This is mainly due to the fact that oral testosterone can have potential side effects on the liver and is associated with more significant fluctuations in hormone levels.
Metabolism and Liver Health: Oral testosterone is processed through the liver before entering the bloodstream. This can potentially strain the liver, and long-term use of oral testosterone may increase the risk of liver damage. Therefore, individuals with pre-existing liver conditions may not be suitable candidates for oral testosterone therapy.
Fluctuating Hormone Levels: Oral testosterone can lead to greater fluctuations in testosterone levels throughout the day compared to other forms of testosterone therapy. This can result in inconsistent symptom relief and less stable hormone balance.
How Long Does Testosterone Take to Work?
Short-term Timeline
Short-term effects of testosterone therapy can occur within the first few weeks to months of starting treatment. These effects may vary among individuals, and not everyone will experience the same results. Here are some common short-term effects and their general timeline:
Increased Energy and Vitality: Many individuals report a boost in energy levels and overall vitality as a short-term effect of testosterone therapy. This increased energy can contribute to improved motivation, productivity, and a general sense of well-being. Some individuals may start noticing this effect within the first few weeks of treatment.
Improved Mood: Testosterone therapy can have a positive impact on mood and emotional well-being. It may help alleviate symptoms of depression, irritability, and mood swings associated with low testosterone levels. Some individuals may experience improvements in mood within a few weeks of starting treatment.
Enhanced Libido and Sexual Function: Testosterone plays a crucial role in sexual health and function. As testosterone levels are restored to a healthier range, individuals with low testosterone may experience an improvement in libido, sexual desire, and sexual performance. This effect can occur within the first few weeks to a couple of months of testosterone therapy.
Reduction in Fatigue: Fatigue and low energy levels are common symptoms of low testosterone. Testosterone therapy can help alleviate fatigue, increasing endurance, and reducing feelings of tiredness. Some individuals may start experiencing a reduction in fatigue within a few weeks of treatment.
Changes in Body Composition: Testosterone therapy can contribute to changes in body composition by increasing muscle mass and reducing body fat. However, noticeable changes in body composition typically take longer to manifest. It may take several months of consistent treatment, along with a proper diet and exercise regimen, to see significant changes in muscle mass and body fat percentage.
It’s important to note that the timeline for experiencing short-term effects can vary among individuals. Factors such as the severity of testosterone deficiency, individual metabolism, and the specific treatment protocol can influence the timing and intensity of these effects. Regular communication with a healthcare professional and adherence to the prescribed treatment plan are crucial to monitor progress and ensure the therapy is effective and safe.
Long-term Timeline
Long-term effects of testosterone therapy can develop gradually over an extended period of consistent treatment. The timeline for these effects can vary among individuals, and it’s important to note that not all individuals will experience the same results. Here are some common long-term effects and their general timeline:
Increased Muscle Mass and Strength: Testosterone plays a significant role in muscle development and strength. With testosterone therapy, individuals with low testosterone levels may experience an increase in muscle mass and strength over time. However, building significant muscle mass and strength requires consistent training, proper nutrition, and time.

Tracking Testosterone Therapy
Monitoring testosterone therapy is important to ensure its effectiveness, safety, and to make any necessary adjustments to the treatment plan. Regular monitoring allows healthcare professionals to assess hormone levels, evaluate response to therapy, and manage any potential side effects. Here are some key aspects of monitoring testosterone therapy:
Hormone Levels:
Blood tests are used to monitor testosterone levels before starting therapy and during treatment. These tests measure total testosterone, free testosterone, and sometimes other hormone levels, such as estradiol (a form of estrogen). Monitoring hormone levels helps determine if testosterone levels are within the desired therapeutic range and if any adjustments to the dosage or frequency of administration are necessary.
Symptom Evaluation:
Regular follow-up appointments with a healthcare professional allow for the evaluation of symptoms associated with low testosterone. Patients can discuss any changes in symptoms, such as improvements or new concerns, during these visits. This helps gauge the effectiveness of the therapy and enables healthcare professionals to make any necessary adjustments.
Side Effect Monitoring:
Testosterone therapy can have potential side effects, and regular monitoring helps detect and manage these side effects. Healthcare professionals will assess for any adverse reactions or complications related to the treatment, such as changes in liver function, cholesterol levels, blood pressure, and hematocrit (red blood cell count).
Physical Examinations:
Physical examinations can be conducted periodically to assess the impact of testosterone therapy on the body. These examinations may include measurements of blood pressure, body weight, body composition, and evaluation of secondary sexual characteristics. They provide a comprehensive view of the overall response to therapy.
Bone Density Monitoring:
In some cases, bone density measurements, such as dual-energy X-ray absorptiometry (DEXA) scans, may be recommended to evaluate the impact of testosterone therapy on bone health. These scans help monitor changes in bone density over time, particularly for individuals at risk of osteoporosis or with specific conditions affecting bone health.
Fertility Assessment (if applicable):
For individuals concerned about fertility, semen analysis may be recommended to assess sperm count and quality. This monitoring helps determine the impact of testosterone therapy on fertility and guides decisions regarding family planning.
