Testicular sperm extraction with intracytoplasmic sperm injection for male infertility [PDF]

open access: yesReproductive Medicine and Biology, 2003
Background and Aims: Testicular sperm extraction (TESE) and intracytoplasmic sperm injection (ICSI) is an effective procedure for the treatment of male infertility, obstructive and non‐obstructive azoospermia. We have reviewed our experience to investigate the correlation of TESE‐ICSI with morphological, biophysical and endocrine profiles in 27 men ...
