The last 20 years have produced developments in the treatment for patients with non-obstructive azoospermia (NOA) who were once considered to be infertile. The combination of intracytoplasmic sperm injection together with various testicular sperm retrieval techniques, including conventional testicular sperm extraction (TESE), microdissection TESE (micro-TESE) and fine needle aspiration (FNA), h...
OBJECTIVES Microdissection testicular sperm extraction (micro-TESE) is an optimal technique of sperm extraction for intracytoplasmic sperm injection. This study is to present our experience in micro-TESE and evaluate the relation of its sperm retrieval rate (SRR) with patients' characteristics, testicular functions, and histological parameters as well as previous sperm retrieval interventions. ...
BACKGROUND Testicular sperm extraction (TESE) with ICSI is becoming the first-line treatment for non-obstructive azoospermia (NOA). Recently, the sperm retrieval rate (SRR) by microdissection TESE was reported to be higher than by conventional TESE. However, a comprehensive comparison between multiple and microdissection TESE patients including histological findings has not been reported. MET...
background: we performed this study to evaluate use of fresh and frozen sperm samples in non-obstructive azoospermia microdissection testicular sperm extraction (micro-tese-icsi) treatment. methods: we performed a total of 82 consecutive in vitro fertilization (ivf) cycles at fertijin ivf center in istanbul, turkey from january 2010 to march 2012. in 43 participants we used fresh sperm and froz...
Testicular sperm extraction (TESE) was performed on patients with non-obstructive azoospermia using the conventional or microdissection technique. First, conventional TESE was attempted on all patients. If the sperm was retrieved successfully, the TESE procedure was terminated. Microdissection TESE was indicated only for patients for whom the conventional sperm retrieval was unsuccessful. Sperm...
