What Are The Side-Effects Of Testosterone Replacement Therapy?
Print PageSide-effects can occur if testosterone is used in excessive quantities. These may include:
- Too frequent or persistent erections (priapism)
- Nausea and vomiting
- Swelling of the ankles
- Acne
- Headache
- Gynecomastia (breast development) due to conversion to estrogen
- Increased appetite
These effects are usually associated with excessive levels of serum testosterone due to incorrect dose. Due to their mode of administration, testosterone gels and creams generally keep testosterone blood levels within the normal therapeutic range for men and therefore side effects are unlikely to occur. Spikes and troughs of testosterone are more likely to occur with injections.
