Exogenous testosterone replacement therapy versus raising endogenous testosterone levels: current and future...

Area of Science:

• Endocrinology
• Men's Health
• Pharmacology

Background:

• Testosterone replacement therapy (TRT) is a key treatment for men with hypogonadism.
• Various TRT formulations exist, but they can impair fertility via the hypothalamic-pituitary-gonadal (HPG) axis.
• Fertility preservation is a significant concern with traditional TRT.

Purpose of the Study:

• To review and compare current exogenous TRT methods.
• To discuss alternative therapies that enhance endogenous testosterone production.
• To explore novel treatments for normalizing testosterone while preserving HPG axis function.

Main Methods:

• Literature review of existing and investigational therapies for testosterone deficiency.
• Comparative analysis of different treatment modalities based on efficacy, safety, and fertility impact.
• Focus on treatments affecting the hypothalamic-pituitary-gonadal axis.

Main Results:

• Exogenous TRT effectively restores testosterone levels but risks fertility.
• Alternative treatments like SERMs, gonadotropins, and aromatase inhibitors show potential for fertility preservation.
• Novel therapies are under investigation to balance testosterone normalization and HPG axis function.

Conclusions:

• TRT is vital for testosterone deficiency symptoms but selecting the optimal therapy is complex.
• Factors like safety, efficacy, cost, and side effects guide treatment decisions.
• Fertility-preserving alternatives are promising but require further development; patient-centered choices are crucial.
