Screening of Yq has become one of the most frequently performed postnatal molecular genetic tests in Egypt. Our purpose was to determine the tag sequence-tagged sites (STSs) in the AZF -region of Yq associated with azoospermia and severe oligospermia in infertile Egyptian men. We analyzed blood samples from 49 infertile men (28 with azoospermia and 21 with severe oligospermia) using multiplex P...

In more than half of infertile men, the cause of their infertility is unknown. Several studies revealed the role of viral infections in male infertility. The aim of the present study was to determine the prevalence of herpes simplex virus-1 (HSV-1) and HSV-2 in semen from asymptomatic infertile male patients, and its association with altered semen parameters. A total of 70 semen samples were co...

Although several genetic causes of male infertility are known, the condition in around 60.0-75.0% of infertile male patients appears to be idiopathic. In some, genetic causes may be polygenic and require several low-penetrance genes to produce a phenotype outcome. In others, pleiotropy, when a gene can produce several phenotypic traits, may be involved. We have investigated whether single nucle...

OBJECTIVE To measure levels of reactive oxygen species (ROS) including H(2)O(2) and O(2)(.-) generation in infertile men and determine whether sperm quality is correlated with levels of ROS triggered by the exogenous reduced form of beta nicotinamide adenine dinucleotide phosphate (NADPH). DESIGN Prospective study. SETTING Male infertility clinic at a tertiary healthcare center. PATIENT(S...

INTRODUCTION Improving the lifestyle of infertile couples led to the preservation of their performance, increase their quality of life, and reduce health cost. So, the aims of this study were to determine the health-promoting lifestyle and its predictors among infertile couples. METHODS In a cross-sectional, analytical study 322 infertile couples referred to an infertility clinic in Tabriz wa...
