Title: Single vs. multiple semen specimens in screening for male infertility factors. A comparison.
Abstract: To reevaluate the number of semen analyses necessary to establish whether further male infertility testing is necessary.The results of three consecutive semen analyses for infertility evaluations were retrospectively reviewed. A male factor was defined by an abnormal semen analysis if either the first specimen of three (single-sample screening) or two of the three specimens (multiple-sample screening) met World Health Organization criteria. Males considered abnormal by multiple-sample screening underwent sophisticated andrologic evaluation.A single-sample conventional semen analysis obtained from 209 males demonstrated a diagnostic accuracy of 10.4% false negatives and a sensitivity of 89.6% when compared to that of multiple-sample analysis. Andrologic evaluation of abnormal males by multiple-sample screening confirmed that 9 of the 11 men with normal first specimens were abnormal; all others were confirmed as abnormal.Analysis of multiple semen specimens provides a reliable screen in the evaluation of male factor infertility when the goal is to minimize the false negative rate of screening tests.
