Semen analysis in adolescents with familial Mediterranean fever.

BACKGROUND

Little is known about sperm health in male patients with familial Mediterranean fever (FMF). In this study, the authors aimed to search the frequency of sperm abnormalities of adolescent boys with FMF and also to investigate whether disease activity or colchicine treatment have negative effects on sperm parameters.

METHOD

The male adolescents older than 14 years with a diagnosis of FMF were investigated retrospectively. Tel Hashomer and pediatric FMF clinical criteria were used for diagnosis of FMF. Patients who had semen analysis were included in the study.

RESULT

Mean age at the diagnosis was 11.13 ± 3.82 years, and mean age at the study was 14.50 ± 0.70 years. The mean sperm concentration was found as 66.26 ± 41.02 million/ml (N > 15 million/ml), the mean total sperm count 113.42 ± 132.39 million (N > 39 million), and the mean sperm motility 51.78 ± 23.70% (N > 40%). Only 8 of 19 (42.1%) patients had normal sperm parameters. Sperm concentration was reduced in two cases, total sperm count was reduced in four patients, and motility was reduced in nine cases. The presence of FMF attacks under treatment was found to be a risk factor for decreased motility in the study group by multivariate regression analysis (odds ratio 0.076, [95% confidence interval 0.005-0.648], P = 0.031). Erythrocyte sedimentation rate at the time of diagnosis was high in patients with low sperm counts compared with those with normal sperm counts (56.00 ± 8.51 vs 24.35 ± 6.32, P: 0.03). Mean colchicine dose at the time of sperm analysis was higher in patients with low sperm motility than that with normal sperm motility (1.72 ± 0.18 vs 1.25 ± 0.08, P: 0.02).

CONCLUSION

Sperm abnormalities of male patients with FMF is not infrequent, and it is linked to both inflammation due to uncontrolled disease and colchicine therapy.
