background: the sperm count and function may be affected by karyotype abnormalities or microdeletion in y chromosome. these genetic abnormalities can probably transmit to the children. objective: in this study, we tried to determine the frequency of karyotype abnormalities and y chromosome microdeletions in severe oligospermic or azoospermic men who fathered sons by icsi. materials and methods:...

PURPOSE We compared vasoepididymostomy to microsurgical epididymal sperm aspiration and intracytoplasmic sperm injection for treatment of epididymal obstruction secondary to vasectomy.
