The emergence of specialized procedures for the acquisition, processing, and cryopreservation of epididymal and testicular sperm in connection with intracytoplasmic sperm injection
specialized procedures acquisition cryopreservation epididymal testicular sperm intracytoplasmic sperm
2009/2/18
Epididymal and testicular spermatozoa have been used widely for ICSI among men with obstructive azoospermia and NOA. New aspiration and biopsy techniques are available, and several sperm prepa...
Morphology of testicular spermatozoa obtained by testicular sperm extraction in obstructive and nonobstructive azoospermic men and its relation to fertilization success in the in vitro fertilization-intracytoplasmic sperm injection system
