Microdissection Testicular Sperm Extraction (MicroTESE) and IVF-ICSI Outcome in Non-Obstructive Azoospermia (NOA)
We evaluated the application of surgical testicular exploration with the aid of a microscope (MictoTESE) to increase the chances of obtaining sperm in men with impaired sperm production, a condition known as non-obstructive azoospermia.
We also evaluated the outcomes of these couples when the sperm obtained were used in ICSI (Intracytoplasmic Sperm Injection) during assisted reproductive technology treatment.
We believe that excellent results may be obtained with the use of the following techniques in the treatment of couples where non-obstructive azoospermia is a significant cause.
Procedure: Microdissection Testicular Sperm Extraction
|Study Design:||Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||Prospective Evaluation of Microdissection Testicular Sperm Extraction in Non-Obstructive Azoospermic Men and Their IVF-ICSI Related Outcomes at ART Treatment.|
- Sperm retrieval rate,mean male and female partner age,mean ICSI and fertilized oocytes, implantation, pregnancy and miscarriage rates.Testicular histology was also compared. [ Time Frame: 17 months ]
- Sperm retrieval associated to pre-operative serum FSH, LH, Total Testosterone,Prolactin, testicular volume and post-operative testicular histology. ICSI and pregnancy results associated to sperm motility. [ Time Frame: 17 months ]

|Study Completion Date:||October 2006|
Men diagnosed with non-obstructive azoospermia and seeking assisted reproductive technology treatment (ART) are candidates for surgical sperm retrieval with the aid of microdissection. We believe that this approach may currently be the best option for these subjects.
We evaluated our surgical sperm retrieval rate associated to their serum LH, FSH, TOTAL TESTOTERONE and PROLACTIN levels, pre-operative testicular volume and also compared to the post-operative histological analysis of fixed testicular tissue specimens collected during the procedure, stained with haematoxylin and eosin.
We also evaluated the outcomes using ICSI based ART for these couples observing mean ICSI and fertilized oocytes, number and quality of embryos transferred, implantation and pregnancy rates.
