reproductive system
abnormal sperm flagellum morphology ( J:288345 )
• no normal sperm flagella are seen; sperm show absent flagella, short, coiled, bent and irregular-caliber flagella
• however, no differences in seminiferous tubule structure or spermatogenic cells are seen
abnormal outer dense fiber morphology ( J:288345 )
• outer dense fibers are chaotically scattered
abnormal sperm axoneme morphology ( J:288345 )
• microtubule doublets are chaotically scattered
short sperm flagellum ( J:288345 )
• testicular and epididymal spermatozoa exhibit short flagella
abnormal sperm head morphology ( J:288345 )
• 89.5% of sperm heads are abnormal, with abnormal head shape and acrosome
