Risk of testicular cancer in men with abnormal semen characteristics: cohort study.

ABSTRACT:

Objective

To explore the associations between semen characteristics and subsequent risk of testicular cancer.

Design

Cohort study.

Participants

32 442 men who had a semen analysis done at the Sperm Analysis Laboratory in Copenhagen during 1963-95.

Main outcome measure

Standardised incidence ratios of testicular cancer compared with total population of Danish men.

Results

Men in couples with fertility problems were more likely to develop testicular cancer than other men (89 cases, standardised incidence ratio 1.6; 95% confidence interval 1.3 to 1.9). The risk was relatively constant with increasing time between semen analysis and cancer diagnosis. Analysis according to specific semen characteristics showed that low semen concentration (standardised incide
