Idiopathic male infertility related to periodontal and caries status

This study was undertaken to evaluate the possible correlation between the periodontal and dental status and sperm pathology in idiopathic male infertility.

The periodontal and caries status and semen quality of 199 men presented with unexplained male infertility were examined. Periodontal and dental factors were analysed by sperm pathology categories.

A total of 106 men had normal sperm parameters, whereas 93 men had some type of spermpathology; 27.95% had oligozoospermia, 23.65% asthenozoospermia, 16.12% cryptozoospermia, 32.25% combined oligo-asthenozoospermia. Poor periodontal status was found in about half of the study group (45.7%). The DMFT index was not a significantly higher in any of the spermpathology groups. The odds ratio of calculus, bleeding on probing (BOP) and BOP at ≥50% of the teeth were significantly higher in the combined group (AOR = 1.04, AOR = 1.13, AOR = 4.92, respectively) in multivariate analyses compared to those in the normozoospermia group. Gingival bleeding in the history and urban residency were the only predictors for pathospermia shown by the logistic regression model (AORs were 1.82 and 2.26, respectively).

Some features of poor periodontal status, as gingival bleeding in the history, presence of calculus and BOP, were associated with oligo+asthenozoospermia in men with idiopathic infertility.
