Determination of laboratory specific percent normal sperm morphology value based on prevasectomy ("fertile") ejaculates.
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.
