[Testicular sperm extraction for non-obstructive azoospermia: results with conventional and microsurgical techniques].
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...
متن کاملClinical Comparison of Conventional Testicular Sperm Extraction and Microdissection Techniques for Non-Obstructive Azoospermia
BACKGROUND We compared the efficacy of microdissection testicular sperm extraction (microdissection TESE) and conventional TESE in patients with non-obstructive azoospermia (NOA) and related the positive sperm recovery to certain variables: follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels, testicular volume and histology. METHODS Sperm retrieval rates (SRR) in patients w...
متن کاملExtended sperm preparation: an alternative to testicular sperm extraction in non-obstructive azoospermia.
Testicular sperm retrieval for the treatment of non-obstructive azoospermia requires the execution of an invasive procedure, with all its possible attending complications and subsequent long-term effects. This study suggests a new non-invasive approach for collection of spermatozoa in these patients: the extended sperm preparation (ESP). ESP consists of conducting a thorough microscopic search ...
متن کاملHigh implantation and pregnancy rates with testicular sperm extraction and intracytoplasmic sperm injection in obstructive and non-obstructive azoospermia.
Thirty-two infertile couples with obstructive and non-obstructive azoospermia were included in this study. Testicular sperm extraction (TESE) was performed in 16 obstructive azoospermic cases where microsurgical sperm aspiration (MESA) or percutaneous sperm aspiration (PESA) were impossible because of totally destroyed epididymis and 16 non-obstructive azoospermia cases with severe spermatogene...
متن کاملConventional multiple or microdissection testicular sperm extraction: a comparative study.
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...
