The Effect of histamine and some Antihistamine in the motitlity of human semin were studid. It shows that the histamine increases sperm metility, further more H2 antihistamine crimetidine had no effect on sperm motility and classical antihistamines decreased sperm motility , where as the inhibition produced by H antihistamine could be over comed with increasing concentration of histamine. Final...

Our objective was to study the incidence of sperm-tail phosphotyrosine immunoreactivity in normozoospermic and asthenozoospermic human sperm samples, its association with sperm motion parameters, particularly hyperactivated motility, and its potential involvement in the pathogenesis of asthenozoospermia. The work was conducted as a prospective experimental study in the Sperm Biology and Androlo...

Background: There are several causes leading to male infertility, like oxidative stress, and nutritional deficiency of trace elements i.e., selenium and zinc. The Zinc is the following only to iron as the most abundant element in the body. Although, Zinc is found in red meat, white meat, fish, and milk; the World Health Organization (WHO) approximates that one-third of world population is defic...

OBJECTIVE One of causes of male infertility is reduced sperm motility. It turns out that the reduced efficiency of the mitochondrial respiratory activity may play a role in the development of this disorder. The aim of our study was to comprehensively determine mitochondrial respiratory activity of sperm with normal and reduced motility. DESIGN Prospective study. SETTING Department of Histol...
