Abstract

Proficiency testing samples for antisperm antibodies (ASAB), sperm count, morphology and vitality were mailed to participating laboratories. The majority participating utilized Immunobead ASAB procedures (81 versus 14% mixed antiglobulin reaction and 5% 'other'), and there was 95.6 ± 1.2% agreement on the presence or absence of ASAB. The majority of laboratories utilized manual (79%) versus computer assisted semen analysis (CASA; 15%) methods. Approximately 64% used the haemocytometer and 26% used the Makler counting chambers for manual counts. Coefficients of variation (CV) in sperm counts ranged from 24 to 138%, with CASA displaying lower overall CV (53 ± 8%) than manual methods (80 ± 9%). A wide variation in the reports of percent normal morphology was noted (CVs calculated from arc sin transformed means ranged from 15 to 93%). Participants using American Society of Clinical Pathologists (ASCP) criteria reported sperm morphology values that were clustered in the 'normal' range (11 out of 12 samples), while those using strict criteria were clustered in the 'abnormal' range (10 out of 12 samples). Good agreement was observed in sperm vitality (overall mean CV = 18%). These data highlight the urgent need for improvement in overall quality of andrology testing and indicate that practical proficiency testing programmes can be made available on a large scale.
