Cryptorchidism, or undescended testes, significantly impairs fertility potential in male patients. Early orchiopexy (testis repositioning) within the first year of life may help preserve fertility.

Area of Science:

  • Pediatric Urology
  • Reproductive Endocrinology
  • Histopathology

Background:

  • Cryptorchidism affects male reproductive health, with potential impacts on fertility.
  • Assessing fertility potential in undescended testes is crucial for timely intervention.

Purpose of the Study:

  • To evaluate fertility index measurements in boys with cryptorchidism.
  • To compare fertility in undescended testes versus descended testes.
  • To determine the optimal timing for orchiopexy to preserve fertility.

Main Methods:

  • Retrospective analysis of 226 male patients (6 months–16 years) with cryptorchidism.
  • Open testis biopsy for fertility index (FI) measurement using light microscopy.
  • Comparison of FI between undescended and descended testes, and with normal testicular values.

Main Results:

  • Fertility index was significantly decreased in undescended testes compared to normal values across most age groups.
  • Significant fertility index differences were observed between undescended and descended testes in patients older than 1 year.
  • Descended testes in unilateral cases showed normal fertility index in boys aged 13 months to 6 years.

Conclusions:

  • Potential fertility is significantly impaired in the cryptorchid testis regardless of age at diagnosis.
  • The descended testis in unilateral cryptorchidism may also show impaired fertility in certain age groups.
  • Orchiopexy within the first year of life is recommended to preserve fertility potential.
