Endocrinological parameters and cell-mediated immunity postoperation for cryptorchidism.

Area of Science:

• Urology
• Reproductive Endocrinology
• Immunology

Background:

• Cryptorchidism, or undescended testes, can affect testicular function and fertility.
• Surgical repair aims to restore testicular position but may not fully reverse potential damage.

Purpose of the Study:

• To evaluate andrological, endocrinological, and cell-mediated immunity (CMI) parameters in postpubertal males after cryptorchidism repair.
• To assess potential correlations between these parameters and fertility outcomes.

Main Methods:

• Assessed sperm parameters (density, motility, viability, morphology), hormone levels (testosterone, dihydrotestosterone, LH, prolactin, FSH), and CMI responses in 25 postpubertal males.
• Patients had undergone surgical repair for unilateral or bilateral cryptorchidism in childhood or early adolescence.

Main Results:

• Approximately 30% of unilateral cases and 3 out of 5 bilateral cases showed reduced sperm density (oligozoospermia or azoospermia).
• Sperm morphology was often abnormal, though motility and viability were generally normal. Hormone levels were within normal ranges, with slightly elevated FSH.
• A significant CMI response to autologous semen was observed in 80% of bilateral and 45% of unilateral cases.

Conclusions:

• Post-cryptorchidism males may exhibit impaired spermatogenesis despite normal hormonal profiles, suggesting potential long-term fertility concerns.
• Elevated CMI responses might indicate an autoimmune component or testicular damage following cryptorchidism and its repair.
• Fertility prognosis for postcryptorchid oligozoospermic patients may be more favorable than for those with other causes of low sperm count.
