title: Determination of laboratory specific percent normal sperm morphology value based on prevasectomy ("fertile") ejaculates.
abstract: Semen assessments were performed on ejaculates from 25 men with proven fertility requesting vasectomy. Multiple cytological slides were made simultaneously from each ejaculate and analyzed by a single technician. The morphology data obtained were analyzed for repeatability. The mean +/- SD for normal sperm morphology was 30.6+/-7.3, and the within-subject repeatability was < or =1 SD of the mean for 17 of 25 ejaculates. Technician and laboratory specific criteria for the percent normal sperm morphology component of a semen analysis report (that are clinically meaningful) can be developed using the approach described herein.
