Sperm quality is critical to predict reproductive alterations caused by immunological factors
or toxicant agents. Yet, no detailed protocol has been published focusing on analyses of …

We used automated sperm morphology analysis to investigate rat sperm morphometry and
morphology in Sprague-Dawley and Wistar rats in three research centers to develop normal …

Infertility has become a major public health problem, with a male factor involved in about half
the cases. Mice are the most widely used animal model in reproductive biology research …

In vitro fertilization (IVF) is widely used in reproduction research, but the sperm of some
inbred strains of mice yield low fertilization rates in IVF. To determine the cause of this …

Background Although spermatozoa with normal morphology are assumed to have uniform
fertilization ability, recent data show that even normal spermatozoa have considerable …

Multiparametric analysis by flow cytometry solves one of the major problems in sperm
evaluation, the inability to test multiple attributes simultaneously in a single cell, which would …

Abstract ICR and C57BL/6J mice have been widely used in several research fields. The
reproductive toxicology parameters, such as fertilization rate, which may differ between the …

The union of male and female gametes creates offspring. The production of these vital
reproductive cells occurs in the testis and ovary during the processes of spermatogenesis …

This study examined a method for analyzing the count, motility, and morphology of mouse
epididymal sperm, optimizing the diluent, incubation time, sample concentration, and …

Spermatozoa are diverse in form and function and these differences impact on their
fertilizing capacity. Because of considerable inter-male and inter-species differences in …
