Chromosome abnormalities in embryos derived from microsurgical epididymal sperm aspiration (MESA) or testicular sperm extraction (TESE) in were normal (41 ± 31%, 48 ± 38%, and 48 ± 31% in MESA, TESA, and EJAC, respectively). If MESA fails to retrieve motile sperm, TESA or TESE can be performed as . orchitis, genetic, radio-/chemotherapy and idiopathic—are comparable (14,33).
