Acquired cryptorchidism (AC) in boys significantly reduces germ cell count and fertility markers, similar to congenital undescended testes (UDT). Early detection and surgical correction are recommended, especially in older boys.

Area of Science:

  • Pediatric Urology
  • Reproductive Endocrinology
  • Histopathology

Background:

  • Acquired cryptorchidism (AC) is a subgroup of undescended testes (UDT) with comparable effects to congenital UDT (cUDT).
  • Histological examination of testicular biopsies from AC patients is crucial for understanding its impact.

Purpose of the Study:

  • To conduct an extensive histological examination of testicular biopsies from boys with acquired cryptorchidism.
  • To assess germ cell count, spermatogonia levels, and malformations in AC patients.

Main Methods:

  • Prospective study involving 21 boys (3-12 years) undergoing orchiopexy for AC.
  • Histological analysis of testicular biopsies using resin semi-thin sections and immunohistochemical stains.
  • Evaluation of germ cells (GC) per tubule (T) and adult dark spermatogonia (Ad-S) per T.

Main Results:

  • Prematurity (19%), small for gestational age (SGA) (9.5%), and family history of UDT (43%) were identified as predictors for AC.
  • A significant reduction in GC/T and Ad-S/T was observed, with more severe alterations in boys aged ≥9 years.
  • No signs of malformation or atypical cells were detected; immunohistochemical stains were negative.

Conclusions:

  • Prematurity, SGA, and family history are potential predictors for AC.
  • AC leads to reduced germ cell counts and fertility markers comparable to cUDT, with increased severity in older boys.
  • Routine testicular checks and parental education are vital; surgical correction is advised upon diagnosis.
