Varicocelectomy May Improve Results for Sperm Retrieval and Pregnancy Rate in Non-Obstructive Azoospermic Men
Objective Improvement in sperm density and motility after varicocelectomy have been widely reported for men with oligoasthenoteratospermia (OAT),However the value of varicocelectomy in azoospermic men remain controversial.In this study we have evaluated the outcome of microsurgical varicocelectomy in nonobstructive azoospermic (NOA) men with clinical varicocele in five years in royan institute....
متن کاملSperm retrieval rates in subgroups of primary azoospermic males.
OBJECTIVES Men presenting with primary infertility and azoospermia may be offered surgical sperm retrieval (SSR) as a prelude to intracytoplasmic sperm injection (ICSI). We evaluated sperm retrieval rates in subgroups of men with azoospermia, based on obstructive aetiology, testicular volume and FSH. METHODS 106 patients with primary infertility underwent clinical evaluation and SSR with perc...
متن کاملTesticular sperm extraction in azoospermic men submitted to bilateral orchidopexy.
BACKGROUND This study was carried out to evaluate whether bilateral orchidopexy represents a poor or good prognostic factor in azoospermic men undergoing testicular sperm extraction (TESE). METHODS One hundred and seven presumed non-obstructive azoospermia (NOA) patients, according to conventional clinical parameters (volume of testis, FSH, clinical history) were submitted to testicular biops...
متن کاملMessenger RNA transcripts of the meiotic regulator BOULE in the testis of azoospermic men and their application in predicting the success of sperm retrieval.
BACKGROUND Testicular sperm retrieval can lead to paternity for azoospermic patients with spermatogenic failure. The human BOULE gene, a meiotic regulator of germ cells, is a gene whose altered expression may be associated with sterility. We determined the levels of BOULE transcripts in the testes of azoospermic patients, and evaluated the relationship between BOULE transcript levels and patien...
متن کاملRecovery of spermatogenesis after microsurgical subinguinal varicocele repair in azoospermic men based on testicular histology.
OBJECTIVE Analyze whether testicular histologic patterns from a group of azoospermic men with varicocele is predictive of treatment outcome after subinguinal microsurgical varicocele repair. MATERIALS AND METHODS Seventeen azoospermic men underwent bilateral open single testis biopsy and microsurgical subinguinal repair of clinical varicoceles. RESULTS Histopathology of testicular biopsies ...
متن کاملHow successful is repeat testicular sperm extraction in patients with azoospermia?
BACKGROUND Little is known about the extraction rate in repeated sperm retrieval procedures in azoospermic patients. This study aimed to assess the feasibility of repeated sperm recovery in these patients. METHODS A total of 1066 azoospermic men had their first sperm recovery between 1 January 1995 and 31 December 2003. A total of 381 men had obstructive azoospermia (OA), 628 nonobstructive a...
