Background Use of cellular phones emitting radiofrequency electromagnetic field (RF-EMF) has been increased exponentially and become a part of everyday life. This study aimed to investigate the effects of in vitro RF-EMF exposure emitted from cellular phones on sperm motility index, sperm DNA fragmentation and seminal clusterin (CLU) gene expression. MaterialsAndMethods In this prospective stud...

AIM To study the immune-modulating and anti-oxidant effects of beta-glucan, papaya, lactoferrin, and vitamins C and E on sperm characteristics of patients with asthenoteratozoospermia associated with leucocytosis. METHODS Fifty-one patients referred to our Sterility Center for semen analysis were selected. Sperm parameters were assessed before and after patient's treatment with beta-glucan, l...

Background: The lipids of the spermatozoa membrane are important for the fluidity and flexibility of spermatozoa. However, spermatozoa’s lipids are the main substrates for peroxidation, which may provoke severe functional disorder of sperm. Objective: The aim of this study was to investigate the fatty acids composition of spermatozoa in men with asthenozoospermia, asthenoteratozoospermia and ol...

Case Report To date, several studies of aneuploidy rate in spermatozoa from infertile men have been published. Most of them found an increase incidence of aneuploid spermatozoa in infertile patients compared with normal donors (Moosani et al, 1995; Finkelstein et al, 1998; McInnes et al, 1998; Pang et al, 1999; Rives et al, 1999; Vegetti et al, 2000). However, in other studies, no differences i...

Cysteine-rich secretory protein 2 (CRISP2) is an important protein in spermatozoa that plays roles in modulating sperm flagellar motility, the acrosome reaction, and gamete fusion. Spermatozoa lacking CRISP2 exhibit low sperm motility and abnormal morphology. However, the molecular mechanisms underlying the reduction of CRISP2 in asthenoteratozoospermia (ATZ) remain unknown. In this study, low ...

OBJECTIVES The objective was to evaluate seminal fluid indices of male partners of infertile couples so as to identify the current status of the contributions of male factor to infertility in our environment. MATERIALS AND METHODS This is a prospective study of the seminal fluid indices of consecutively consenting male partners of infertile couples seen at the Fertility and Endocrinology Rese...

Abstract Study question Dose Testis expressed 44 (TEX44) gene associated with spermatogenesis and TEX44 mutations required for male infertility ? Summary answer is in testis participated spermatogenesis. And of may be involved risk asthenozoospermia lead to subfertile. What known already The World Health Organization estimates that 7-9 % population worldwide struggle infertility. Asthenoteratoz...

Background: There is growing evidence that damage to spermatozoa by reactive oxygen species (ROS) play a key role in male infertility. Objective: The aim of the present study was to assess the antioxidant status of seminal plasma by measuring total antioxidant capacity (TAC) and activities of catalase and superoxide dismutase (SOD) in men with asthenozoospermia, asthenoteratozoospermia and olig...
