BACKGROUND Patients with varicocele comprise 15% of males in general population. Varicocele is considered the most cost-effectively treatable cause of male infertility. We introduce a modification in technique of subinguinal varicocelectomy and review the outcome of 58 patients from July 2000 to July 2002. METHODS Four out of the 58 cases had both pain and infertility. For the 31 infertility ...
background: male infertility is a multifactorial disorder, which affects approximately 10% of couples at childbearing age with substantial clinical and social impact. genetic factors are associated with the susceptibility to spermatogenic impairment in humans. recently, sept12 is reported as a critical gene for spermatogenesis. this gene encodes a testis specific member of septin proteins, a fa...
Background Sperm motility is known as an effective parameter in male fertility and it depends on energy consumption. Low level LASER irradiation could increases energy supply to the cell by producing of adenosine triphosphate (ATP). The purpose of this study is to evaluate how the low level LASER irradiation affects the human sperm motility. MaterialsAndMethods Fresh human semen specimens of as...
Background: The aim of present study was to estimate the levels of some Trace element (Lead, Copper, Cobalt, Chromium, and Cademium) concentrations in Asthenospermia and Normospermia by atomic absorption method, in comparison with control (Fertile), Estimate concentration of (MDA) Malondialdehyde and Total protein concentration in semen specimens.Also relationships between mentioned components ...
OBJECTIVE To investigate the clinical effect of microsurgical varicocelectomy on severe oligo-asthenospermia patients failing in fertilization assisted by intracytoplasmic sperm injection. PATIENTS AND METHODS From January 2013 to August 2014, forty-nine patients with severe oligo-asthenospermia and serious varicoceles were treated by microsurgical varicocelectomy after failing in fertilizati...
ABSTRACT Background and Objectives: sperm motility mainly depends on aerobic glycolysis, and lactate dehydrogenase (LDH) is a key enzyme in the last step of this process. On the other hand, fructose is considered as the main energy source for sperm motility. Therefore, this study aimed to evaluate the LDH activity and fructose levels and their cor...
Introduction: Leukemia inhibitory factor is a secreted glycoprotein with a range of molecular weight forms, from 38-67kd, resulting from differential glycosylation of protein of approximately 20Kd. LIF has the four a helix cytokine structure that contains six cysteine residues, already known to occur in many hematopoietic factor. LIF is expressed at high constitutive in human fallopian tubal ep...
Background: Oxidative stress and decreased antioxidant levels have been projected as a potential factors involved in the pathophysiology of diverse male infertility types, including asthenospermia. The generation of reactive oxygen species (ROS) in the male reproductive tract has become an actual concern because of their probable noxious effects, at high levels, on physical properties of sperm ...
Male factor is the sole reason or a component for infertility in 20 and 30% of cases respectively. Medical treatment is preferred for patients with testicular failure due to endocrine or exocrine diseases. Although the infertility may be due to a pathology in the hypothalamic- pituitary axis, the majority of the cases occurs as results of testicular failure. In general medical treatment modalit...
