Testosterone therapy can be administered through several different methods, each with its own administration route and absorption characteristics.
How is Testosterone Therapy Administered?
Testosterone therapy is available in various forms, including injections, topical gels and patches, and oral capsules. Injectable testosterone can be administered intramuscularly, with formulations like testosterone enanthate and cypionate typically given every one to two weeks, while testosterone undecanoate requires less frequent injections, every 10 weeks, after an initial loading phase [1]. Topical testosterone is applied daily to the skin, either as a gel, solution, or patch [2]. Oral testosterone formulations, such as testosterone undecanoate capsules, are taken twice daily with meals [3].
What are the Different Types of Testosterone Gels and Patches?
Testosterone gels are applied daily to the skin, usually on the shoulders or upper arms. Examples include AndroGel and Testim [2]. Transdermal patches, like Androderm, are also applied daily to the skin [2]. Some newer formulations, like Natesto, are nasal gels applied multiple times a day [4].
What are the Options for Injectable Testosterone Therapy?
Injectable testosterone provides a common and effective method of hormone replacement. Common formulations include testosterone enanthate and testosterone cypionate, which are typically injected every one to two weeks [1]. Testosterone undecanoate is another option, administered intramuscularly every 10 weeks following an initial loading dose [1]. There are also options for more frequent injections, such as testosterone propionate given every two to three days [1].
Are There Oral Forms of Testosterone Therapy?
Yes, oral testosterone therapy is available, though it has historically had limitations due to liver toxicity. Current oral formulations, like testosterone undecanoate capsules (e.g., Jatenzo), are designed to bypass the liver and are taken with food [3].
What Should Patients Consider with Testosterone Therapy?
Patients considering testosterone therapy should discuss the various administration methods with their healthcare provider to determine the most suitable option based on individual needs, lifestyle, and medical history. Factors like convenience, frequency of application or injection, potential side effects, and cost can influence the choice of therapy [5].
