HCG and Clomid Dosing Post Long-Term TRT

Initial Recovery Protocol with HCG

• The American Urological Association recommends initiating HCG at 500 IU subcutaneously 3 times weekly (1,500 IU total per week) to restore intratesticular testosterone production in men recovering fertility after long-term TRT 1
• The dosing range for HCG can extend from 500-2,500 IU per week, with typical administration of 250-500 IU given 2-3 times weekly, as suggested by the Praxis Medical Insights 1
• For hypogonadotropic hypogonadism, initial treatment uses HCG injections 500-2,500 IU, 2-3 times weekly, until testosterone levels normalize, according to The Journal of Urology 2

Monitoring and Escalation Strategy

• The Praxis Medical Insights recommends checking testosterone levels at 2-3 months to assess testicular response and measuring LH and FSH to confirm they remain suppressed initially, then gradually recover 1
• If testosterone remains low after 3 months on HCG alone, the Praxis Medical Insights suggests adding FSH 75-150 IU three times weekly 1

Combined Therapy Approach

• The American Urological Association and the American Society for Reproductive Medicine support combination therapy for infertile men, which may include aromatase inhibitors, HCG, selective estrogen receptor modulators (SERMs), or combinations thereof, as stated in The Journal of Urology 3
• Combined HCG and FSH therapy provides optimal outcomes for fertility preservation, according to the Praxis Medical Insights 4

Critical Timing Considerations

• Approximately 67-90% of men eventually recover spermatogenesis after TRT cessation, but this can take 6-24 months, as reported by the Praxis Medical Insights 1
• Older age and longer duration of TRT predict slower and less complete recovery, according to the Praxis Medical Insights 1
• Although most azoospermic males recover sperm after cessation of testosterone therapy, the time course may be months or rarely years, as stated in The Journal of Urology 2

Common Pitfalls to Avoid

• The American Urological Association warns that testosterone monotherapy should never be prescribed to males interested in current or future fertility, as it provides negative feedback causing inhibition of gonadotropin secretion and can result in oligospermia or azoospermia 3, 2
• Excessively high HCG doses should be avoided, as they can cause receptor desensitization, according to the Praxis Medical Insights 1

Mechanism of Action

• HCG mimics LH action directly on testicular Leydig cells, maintaining intratesticular testosterone levels necessary for spermatogenesis, as explained by the Praxis Medical Insights 4
