OBJECTIVE
To determine: [1] what percentage of men in an infertile relationship will have a semen abnormality, [2] the average value for each semen parameter in this group of men, [3] the distribution of abnormal semen parameters in this group, and [4] if our data support the hypothesis that sperm concentration is declining.
DESIGN
Retrospective cohort study.
SETTING
County hospital university-based infertility clinic.
PATIENT(S): Male partners of women presenting for an infertility evaluation.
INTERVENTION(S): Semen specimens were collected after 2-5 days of abstinence.
MAIN OUTCOME MEASURE(S): Sperm concentration, motility, and morphology.

CONCLUSION(S): No decline in sperm density was revealed in semen collected by men presenting for an initial screening semen analysis.
