Around 10% of males with idiopathic azoospermia or oligozoospermia, which are important causes of male infertility, have partial deletions on the long arm of the Y chromosome. To develop a rapid and accurate detection system for screening major Y deletions found in infertile men, we developed a multiplex PCR system that can simultaneously amplify five loci on the Y chromosome, SRY, AMELY, DBY, ...

OBJECTIVES To study the association between copper, magnesium and malondialdehyde levels in seminal plasma of oligozoospermic, azoospermic in relation to normozoospermic men. METHODS The present study was conducted at the Chemistry and Biochemistry department, College of Medicine, Al-Nahrain University, Baghdad-Iraq during September 2007 to February 2008 after obtaining approval from the rese...

Yq microdeletions are the leading genetic cause of male infertility and its detection in clinically relevant for appropriate genetic counseling. The objective of this study was to determine the frequency of Y microdeletion in a group of Tunisian infertile men and to compare the prevalence of these abnormalities with other countries and other Tunisian reported series. Totally, 105 Tunisian idiop...

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...

One hundred one azoospermic males were subjected to fine needle aspiration cytology (FNAC) of the testis and 11 of them underwent testicular biopsy as well. In 99 cases, the aspiration was adequate for classifying into different categories, which are as follows: Sertoli cell only syndrome (46), normal spermatogenesis (27), hypospermatogenesis (10), tubular/peritubular sclerosis (10) and maturat...

The objective of research was to determine the sensitivity, specificity and positive predictive value of serum follicle stimulating hormone and testis size in predicting spermatogenesis in infertile men with azoospermia. In a prospective study, azoospermic men were studied. Serum follicle stimulating hormone measurement and scrotal sac ultrasonography were performed. Bilateral testis biopsy was...

BACKGROUND Partial deletions of the AZFc region of the Y chromosome were reported to be a significant risk factor for oligo-/azoospermia. In this study, we assessed the occurrence and frequency of partial AZFc microdeletions in patients with spermatogenic failure and in controls with normal spermatogenesis. METHODS In a retrospective study design, gr/gr, b1/b3 and b2/b3 deletions were analyse...

BACKGROUND Y chromosome microdeletions are associated with severe male factor infertility. In this study, the success rate of testicular sperm retrieval was determined for men with deletions of AZF regions a, b or c. METHODS AZF deletions were detected by PCR of 30 sequence-tagged sites within Yq emphasizing the AZFa, b and c regions. Semen analysis and diagnostic testis biopsy or testicular ...

The aim of this study is to evaluate the feasibility of testicular sperm extraction (TESE) in a cancerous testicle during orchiectomy for testicular neoplasm. This is a retrospective study and includes case histories of four azoospermic patients with incidental testicular cancer. None of the patients had fathered children prior to surgery and all patients were strongly motivated by the desire t...

OBJECTIVES To investigate the natural courses of mild, moderate and severe idiopathic oligozoospermia, and which factors or semen variables were of utmost importance in predicting the courses. METHODS A total of 208 men (age 29-47years) who were diagnosed with mild, moderate and severe idiopathic oligozoospermia in a 9-year-period between January 2000 and December 2008 were followed up for mo...
