Mammalian sperm cells must respond to cues originating from along the female
reproductive tract and from the layers of the egg in order to complete their fertilization …

Capacitation is an important physiological pre-requisite before the sperm cell can acrosome
react and fertilize the oocyte. Recent reports from several laboratories have amply …

Flow cytometry is now a recognized methodology within animal spermatology, and has
moved from being a research tool to become routine in the assessment of animal semen …

Expression of cyclooxygenase 2 (COX2, now known as PTGS2), prostaglandin E2 synthase
(PTGES, PGES), and prostaglandin F2α synthase (PGFS), of the respective receptors …

It is hard to fathom that one of the most highly differentiated cells in the body, the
spermatozoon, spends over half of its developmental life without the capacity for nuclear …

Male infertility refers to the inability of a man to achieve a pregnancy in a fertile female. In
more than one-third of cases, infertility arises due to the male factor. Therefore, developing …

The present study aimed to evaluate the effect of single-layer centrifugation (SLC) through a
species-specific colloid (Androcoll-B; patent pending, JM Morrell) on bull sperm quality …

This study was conducted to investigate the complex interactions between oviducts and
cryopreserved spermatozoa. Herein we report the dynamic changes in bull sperm functions …

SRC-related tyrosine kinases are suggested to play a role in the increase of sperm protein
phosphotyrosine content that occurs during capacitation. In our laboratory, we previously …

Males have evolved species-specifical sperm morphology and swimming patterns to adapt
to different fertilization environments. In eutherians, only a small fraction of the sperm …
