Objective: To study the influence of tumour necrosis factor (TNF) antagonists on spermatogenesis in a cohort of patients with spondyloarthritis (SpA).
Patients And Methods: Semen samples of 26 patients with SpA were analysed according to WHO 1999 guidelines with and without TNF blocking agents (infliximab, etanercept or adalimumab).
Results: were compared with semen samples of 102 healthy volunteers. Results Sperm abnormalities were found in 10/11 patients without anti-TNF therapy. The sperm of these 11 patients had significantly poorer motility (p=0.001) and vitality (p=0.001) than found in 15 patients tested during longstanding anti-TNF therapy, but sperm concentration and morphology were similar in the two groups. There was no significant difference of sperm quality between healthy controls and anti-TNF treated patients with SpA. Notably, sperm abnormalities were also found in 102 healthy controls.
Conclusion: Sperm abnormalities are a common finding in healthy men, they are more pronounced in patients with active SpA. The sperm quality of patients with SpA with inactive disease receiving long-term TNF inhibition is comparable to that in healthy controls. The data support continuation of anti-TNF treatment when fatherhood is planned.
