Reviews in endocrine & metabolic disorders·2024

Testosterone therapy options are expanding beyond traditional uses for hypogonadism. New formulations aim to improve patient outcomes and offer more choices for conditions like aging and sexual dysfunction.

Area of Science:

  • Endocrinology
  • Pharmacology
  • Reproductive Health

Background:

  • Testosterone replacement therapy (TRT) has been a standard treatment for hypogonadism for decades, primarily using injections and pellets.
  • Emerging research explores testosterone's potential in male contraception, aging (late-onset hypogonadism), muscle wasting (e.g., HIV), erectile dysfunction, and female sexual dysfunction.

Purpose of the Study:

  • To review the chemistry, mechanism of action, and metabolism of testosterone.
  • To discuss the pharmacokinetics, pros, and cons of various testosterone formulations.
  • To summarize currently available testosterone preparations.

Main Methods:

  • Literature review of testosterone chemistry, pharmacology, and clinical applications.
  • Analysis of pharmacokinetic data for different testosterone delivery systems.

Related Experiment Videos

  • Comparison of advantages and disadvantages of various testosterone formulations.

    • Main Results:

    • Several new testosterone administration methods have been developed, including transdermal patches, gels, buccal tablets, and long-acting esters.
    • These novel formulations aim to mimic physiological testosterone levels, enhance patient acceptance, and broaden treatment accessibility.
    • The review covers established and novel delivery systems, detailing their properties and clinical relevance.

    Conclusions:

    • Testosterone therapy is evolving with new formulations offering improved physiological profiles and patient convenience.
    • The expanded therapeutic applications and delivery options provide greater flexibility for managing various conditions.
    • A comprehensive understanding of available testosterone preparations is crucial for effective clinical practice.
