Abstract

To develop a method that could accommodate microvolumes of solubilized human zona pellucida (ZP) and sperm for assessing the induction of the acrosome reaction.A microassay using 1 microliter of 2.5, 1.25, 0.6, 0.3, and 0.125 ZP/microliter incubated with 1 microliter of a highly motile sperm suspension for 60 min. As a control and parallel to the microassay a standard acrosome reaction technique was performed.No significant differences were observed between the percentage acrosome reacted sperm reported by the two assays under basal conditions (spontaneous) or after induction with a Ca2+ ionophore or solubilized ZP. At a ZP concentration of 0.6 ZP/microliter, the percentages of acrosome-reacted spermatozoa in both techniques were significantly higher compared to the spontaneous acrosome reaction results, namely, 18% and 17%, compared to 10% and 10%, respectively. An approximately 30% level of acrosomal exocytosis was induced with 2.5 ZP/microliter in both methods.This newly devised microtechnique is easy and rapid to perform, is repeatable and facilitates the use of minimal volumes of solubilized human ZP (even a single ZP) for assessment of the inducibility of the acrosome reaction of a homologous sperm population.

Abstract

The objective of this work was to assess the power of the hemizona assay to predict in vitro fertilization (IVF) results using receiving operating characteristics (ROC) analysis. In a tertiary medical center setting, 94 couples undergoing IVF were included in the study comparing their fertilization results to sperm function during the hemizona assay. Using ROC analysis, fertilization in IVF (mature oocytes only) was compared to performance of the sperm in the sperm-zona pellucida binding test as expressed by hemizona index (HZI; [number of test sperm bound/number of control sperm bound] x 100). The IVF results were as follows: 32 patients had no fertilization (0%), 55 patients fertilized all of the oocytes (100%), and 7 patients fertilized between 14% and 85% of the oocytes. Modified ROC analysis was used to determine the best threshold for fertilization success or failure, depending upon how the data are viewed. A HZI of 40-43 separated the 100% fertilization group from the other groups, with a true positive rate of 87% and a true negative of 83%. Conversely, a HZI of 4-5 separated the 0% fertilization versus partial or total fertilization, with a true positive rate of 100% and true negative rate of 71%. Sperm performance in the hemizona assay as measured by the HZI reflects performance in IVF and benefits couple evaluation and counseling.

Abstract

To achieve a better understanding of the variability in sperm and oocyte binding capacities will optimize use of the hemizona assay (HZA) as a predictor of sperm function.Limitations of the HZA were more clearly delineated by current studies: (1) variability of sperm binding capacity of men over a 90-day interval; (2) variability of sperm binding using different oocytes; and (3) lower limits of the number of sperm bound from the fertile control in two laboratories.Semen was obtained from proven fertile men and one subfertile individual.The number of sperm tightly bound to the hemizona were measured and compared.In the initial study, 6 fertile control men exhibited a similar degree of variability in zona binding when studied over a 90-day interval. Average sperm binding for individuals ranged from 68 to 127. Second, 3 of the 15 simultaneous assays showed very low numbers of sperm bound, indicating that 20% of the zonae had poor binding. Third, from 18 men who had 0% fertilization in an in vitro fertilization system using mature oocytes, evaluation of their sperm by HZA was performed. The sperm bound poorly and the 95% confidence interval was 20 sperm bound. Thus, the fertile controls should bind greater than 20 sperm to distinguish them from the infertile group in the HZA system resulting in a valid assay.With these guidelines, applications of the HZA may be made with greater reassurance of a valid bioassay of sperm fertilizing potential.
