Summary

Long-term estrogen therapy in males causes significant testicular damage, including reduced germ cells and altered Sertoli and Leydig cells. This study details histological changes in human testes after prolonged estrogen treatment.

Area of Science:

  • Endocrinology
  • Reproductive Biology
  • Histopathology

Background:

  • Estrogen therapy is used for prostate cancer, causing testicular atrophy and reduced sperm production.
  • Previous studies documented testicular changes after short-term (21 days) and over 1-year estrogen treatment.
  • Limited histological data exists for human testes after more than 1 year of estrogen therapy.

Observation:

  • This study examined testicular histology in five male transsexuals undergoing estrogen therapy.
  • Treatment durations ranged up to 5.5 years.
  • Histological analysis revealed significant alterations in testicular tissue.

Findings:

  • Prolonged estrogen exposure led to a marked reduction in germ cells.
  • Vacuolation of Sertoli cells and decreased Leydig cell populations were observed.
  • These changes indicate severe disruption of testicular function with extended treatment.

Implications:

  • Findings highlight potential risks of long-term estrogen therapy on male reproductive health.
  • Understanding these histological changes is crucial for managing patients on hormone therapy.
  • Further research may explore reversibility and therapeutic interventions for estrogen-induced testicular damage.
