Pregnancies using sperm retrieved from the epididymis or extracted from the testis in two cases of obstructive azoospermia

Two men with obstructive azoospermia were treated by testicular exploration. Microscopic epididymal sperms aspiration [MESA] was used in the first patient and testicular epididymal sperms extraction [TESE] in the second. The sperms retrieved in each case were used for intracytoplasmic sperm injection [ICSI] of metaphase 2 oocytes obtained from their respective female partners. Clinical pregnancies were achieved in both cases
