The Neglected Laboratory Test The Semen Analysis

Abstract

Sixty-four laboratories from Connecticut, Massachusetts, and California were involved in a comparison of the types of semen analyses offered. The collected data indicate that there is a wide range of normal values for each parameter considered in a semen analysis. Very few laboratories gave simple and precise instructions for collection of the specimen. In many instances there was no record of the collection time or of the arrival time of the specimen at the laboratory. Most laboratories did not report motility or forward progression at time intervals, and abnormal morphology was not broken down according to the types of abnormalities involved. These data indicate the absolute need for adequate standardization of this important test, which is the basis upon which the clinician makes the important decision of implicating the male partner in the couple's infertility problem.

Measurement of Concentration and Viability in Stallion Sperm

“…Jequier and Ukombe counted human sperm and reported a high coefficient of variation (44%) even though the operators were experienced in the process [13]. Hemacytometer variability has been attributed to a lack of uniformity in laboratory techniques [14], the type of counting chamber [4,15], how well the sample is mixed [16], pipetting technique [17], and the technician [13].…”

Usefulness of Sperm Quality Analyzer-v (Sqa-V) for the Assessment of Sperm Quality in Infertile Men

“…Methods for semen analysis are based on subjective evaluation using standard optical microscopy or on indirect, more objective methods. In addition, the problem for the clinician is the fact that conventional parameters such as concentration, motility and morphology do not always exactly correlate with fertility potential [1,2], making the interpretation of the procured data difficult. All these factors implicate an absolute need for objectibility and standardization of semen analysis, which has led to the development of several semi-computerized and computerized measuring devices [3][4][5].…”

Functional evaluation of dog ejaculates with priority given to the aspect of acrosome integrity

“…The majority of authors who have devoted themselves to the ma�er of the fertility of dogs emphasise the primary importance of the high-quality analysis of ejaculates in dogs with an unknown level of reproductive functions and dogs with fertility disorders, but also the examination of ejaculates prior to their preservation (Deibel et al, 1976;Chong et al, 1983;Dunphy, 1989;Iguer-Ouada and Verstegen, 2001a,b).…”
