Fertilization and early embryology: Does zona pellucida thickness influence the fertilization rate?

1 May 1995

Abstract excerpt

In human in-vitro fertilization (IVF), the cumulus oophorus is routinely removed to assess fertilization and hence the thickness of the zona pellucida is measurable. This study aimed to measure the thickness of the zona pellucida and to assess its influence on fertilization rate in IVF programmes. The zona pellucida thickness varies from 10 to 31 microns with a mean of 17.5 microns. One-way analysis of variance...
