Schistosomiasis or bilharziasis is a disease caused by Schistosoma. When infecting men the most common parasites are Schistosoma mansoni, Schistosoma japonicum and Schistosoma haematobium. The Schistosoma mansoni is the only endemic parasite in Brazil. We present a case of testicular schistosomiasis simulating malignancy. The case was treated successfully by excisional biopsy and praziquantel t...

Background: Germ cell aplasia is a type of azoospermia characterized by hormonal abnormalities as well as histopathological features. Objective: To assess hormonal and histological aspects of germ cell aplasia among infertile men in Gaza Strip. Materials and methods: A total of 375 infertile men visiting the Specialized Medical Centers in Gaza strip were subjected for testicular biopsy. Out of ...

INTRODUCTION Azoospermia affects more than 10% - 15% of infertile male subjects attending infertilty clinics. At present, testicular biopsy is the golden standard procedure for evaluating spermatogenesis status in men with azoospermia. Semen collection and analysis is a non-invasive method and has proven to be valuable in the evaluation of spermatogenesis. Identification of seminal plasma marke...

background:   objective: to investigate if the measurement of inhibin-b can help surgeon to reduce unnecessary diagnostic testicular biopsies in males with azoospermia.   materials and methods: this cross-sectional study was done during july 2006 to september 2007 on 41 patients with azoospermia. fsh and inhibin-b were measured and bilateral open testicular biopsy was performed for all patients...

background: to evaluate predictive factors of successful microdissection-testicular sperm extraction (md-tese) in patients with presumed sertoli cell-only syndrome (scos). materials and methods: in this retrospective analysis, 874 men with non-obstructive azoospermia (noa), among whom 148 individuals with diagnosis of scos in prior biopsy, underwent md-tese at department of andrology, royan ins...

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 ...

BACKGROUND We hypothesized that infertile men with varicoceles have molecular/genetic defects that interact with varicoceles to induce infertility. Studies directly on testis tissue appeared to be a way to link histology, markers for molecular/genetic defects and spermatogenesis, but testis biopsies may induce morbidity. In this report, we present safety and efficacy data on ultrasonically guid...

Testicular hyperechogenic foci (THF) are associated with Klinefelter's syndrome, cryptorchidism, infertility, and testicular germ cell neoplasia. The aims of the study were to evaluate THF in relation to etiology of azoospermia and to Sertoli cell dysfunction. The structures inside the scrotum of consecutive non-vasectomized, azoospermic were examined by ultrasonography, and hormone (FSH, LH, t...
