Influence of tumor necrosis factor α inhibitors on testicular function and semen in spondyloarthritis patients
Spondyloarthritis frequently strikes young men during sexual maturation. Patients are often chronically treated with tumor necrosis factor a blockers. We demonstrated the safety of this therapy on testicular function and spermatogenesis.

To evaluate sperm parameters and sexual hormones in young males affected with spondyloarthritis (SpA) before and after 1 year of anti–tumor necrosis factor (TNF) α treatment.
Prospective case-control study.
Rheumatology and human reproduction pathology units at a university hospital.
Ten SpA outpatients attending the rheumatology clinic; 20 healthy control subjects attending the unit of human reproduction pathology within an infertility prevention program.
At baseline and after a 12-month treatment, disease activity was assessed and an andrologic evaluation made.
Main Outcome Measure(s):
Rheumatologists assessed anamnestic, clinical, functional, and biomarker data. Andrologists evaluated semen analysis, fluorescence in situ hybridization for chromosomes X, Y, 13, 18, and 21, FSH, LH, and T plasma levels, and testicular color Doppler ultrasound.
At baseline, SpA patients showed reduced sperm motility, higher plasma LH and FSH, and lower T levels compared with control subjects; a significant correlation between disease activity and sperm quality was found. After treatment, a statistically significant decrease in sperm aneuploidies and normal hormone levels were observed.
Although inflammation in SpA appears to be related to impaired testicular function, anti–TNF-α agents seem to be safe on testicular function and fertility.
