The objective of this study was to elucidate the missense Glu298Asp polymorphism within exon 7 of the endothelial nitric oxide synthase (eNOS) gene in infertile men with asthenozoospermia and its potential role in sperm motility. In this prospective controlled study conducted in our andrology unit, we investigated the frequency of the 894G>T polymorphism (Glu298Asp variant) within exon 7 of the...
BACKGROUND Asthenozoospermia is one kind cause of male infertility. Nevertheless, no specific etiology can be identified by routine tests in some cases. Recently, it has been shown that leptin plays a critical role in male fertility. However, the link between leptin and sperm motility is yet to be determined. The aim of this study was to explore association between seminal and serum leptin leve...
Background: Asthenozoospermia, a disorder of sperm motility, is a common cause of human male infertility and is found to play a role in approximately 19% of infertile patients. Epidemiological studies indicated a link between environmental pollutants, lifestyle changes, and dietary habits and infertility. In view of the fact that nutrition is coming to the fore as a major environmental factor, ...
Approximately 15% of human couples are affected by infertility, and about half of these cases of infertility can be attributed to men, through low sperm motility (asthenozoospermia) or/and numbers (oligospermia). Because mitochondrial genome (mtDNA) mutations are identified in patients with fertility problems, there is a possibility that mitochondrial respiration defects contribute to male infe...
