Nuclear sperm quality in total polymorphic teratozoospermia and its impact on intracytoplasmic sperm injection outcome.

abstract：:Between 1994 and 2010, a total of 123 patients with obstructive azoospermia due to aplasia of vas deferens (CAVD) were surgically treated. In 110 patients, the condition was bilateral (CBAVD), 13 men had unilateral aplasia (CUAVD), and 10 patients additionally had aplasia of one kidney. All patients underwent CFTR gen...
