Outer dense fibers abnormalities in spermatozoa of IOAT patients and their relation to oxidative stress and sperm motility
INTRODUCTION & OBJECTIVES: Human Spermatozoa are characterized by certain features that differentiate them from simple Flagella. One of these features is the presence of outer dense fibers (ODFs). ODFs are nine fibers surrounding Axoneme in the midpiece and extend to variable length through the principal piece. They represent about 30% of the protein portion of human spermatozoa and accordingly they ... Read more

Efficacy of Tamoxifen and L- carnitine on Sperm Ultrastructure and Seminal Oxidative Stress in patients with idiopathic Oligoasthenoteratozoospermia.
Idiopathic oligoathenoteratozoospermia (iOAT) is a common finding in the evaluation of male infertility. Oxidative stress (OS) may underlie its pathology. Tamoxifen and L-carnitine are used to treat idiopathic male infertility. The aim of this work was to detect the efficacy of tamoxifen and L-carnitine on sperm parameters, sperm ultrastructure and seminal OS in iOAT patients. Sixty patients were recruited for ... Read more
