Delayed puberty occurs when an adolescent’s body does not begin to develop secondary sexual characteristics at the expected age, which is generally around 14 years for boys. This condition can be a source of distress and anxiety. Testosterone injections are a common medical intervention used to induce puberty, helping to initiate physical changes and promote male characteristics.
Common and Immediate Side Effects
Testosterone injections can lead to various common and immediate side effects, many of which mirror the natural changes experienced during puberty. Acne is a frequently observed side effect, resulting from the stimulation of sebaceous glands by increased testosterone levels. This can manifest as oily skin and breakouts.
Injection site reactions are also common, including pain, redness, or swelling at the area where the testosterone is administered. These reactions are typically localized and temporary. As testosterone levels rise, an increase in body hair growth, particularly on the face and body, can be noticed.
Voice deepening is another expected change, occurring as the vocal cords thicken due to hormonal influence. Some individuals may also experience an increased libido or sex drive. Mood changes, such as increased irritability or aggression, have been reported.
Potential Long-Term and Serious Side Effects
While testosterone injections are generally safe, there are potential long-term and serious side effects that warrant careful consideration. One significant concern is the premature closure of growth plates, also known as epiphyseal fusion. This can potentially impact a person’s final adult height if not carefully managed, although short-term, low-dose testosterone is generally not associated with compromising height.
Liver toxicity is a rare but serious potential side effect, though it is more commonly associated with oral forms of the hormone rather than injections. Cardiovascular risks, such as changes in cholesterol levels or elevated blood pressure, can also occur. Monitoring lipid profiles is an important aspect of long-term treatment.
Fluid retention, or edema, particularly swelling in the ankles, is another possible side effect. This typically involves mild sodium and water retention. Furthermore, testosterone injections can impact future fertility by suppressing the body’s natural production of testosterone and sperm, which can lead to smaller testicles.
Monitoring and Management of Side Effects
Healthcare providers closely monitor patients undergoing testosterone therapy for delayed puberty to manage potential side effects. Regular blood tests are a standard practice, used to check testosterone levels, liver function, and lipid profiles, including cholesterol. These tests help ensure hormone levels are within a therapeutic range and detect any adverse effects on organs.
Bone age assessments are also performed periodically to monitor the maturation of growth plates and assess any potential impact on final adult height. Dosage adjustments may be made to optimize the treatment while minimizing side effects. Symptomatic treatments are employed for common side effects, such as topical or oral medications for acne. Open communication with the physician is encouraged to address any concerns or new symptoms that arise during treatment.
Important Considerations and When to Seek Medical Advice
Patients and their parents should report any unusual or severe symptoms to their healthcare team. Adherence to the prescribed regimen is important for both efficacy and safety. Any deviation from the dosage or schedule should be discussed with the doctor.
Specific warning signs include severe pain at the injection site, symptoms of liver issues such as jaundice (yellowing of the skin or eyes), or significant mood disturbances like severe aggression or depression. Signs of an allergic reaction, such as difficulty breathing or a rash, also require urgent medical evaluation. Communication with the healthcare provider ensures that any serious complications are addressed without delay.
