Background: Since cellular membranes play key role in the physiological pathways of the cell, such as fertilization through almost every cellular function to cell division, it is very important to assess the structural and functional activity of the sperm membrane. In this study, a new method for measurement of sperm membrane stability measured the amount of zinc which liberated after being exp...
and normal morphology. Curiously, some previous studies have also focused on elucidating the relationship between HPV-infection with sperm function and male infertility.
