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

Oxidative stress and sperm motility in spermatoozoa of IOAT patients and their relation to outer dense fibers abnormalities
INTRODUCTION AND OBJECTIVE: Outer dense fibers (ODFs) are nine fibers surrounding Axoneme in the midpiece and extend to variable length through the principal piece of spermatozoa. They represent about 30% of the protein portion of human spermatozoa and accordingly they are affected by any pathology that can affect protein content of spermatozoa as in presence of oxidative stress (OS). ODFs ... Read more
