Summary
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.
