Na obstrutiva há produção normal de espermatozoides, mas há uma patologia obstruindo a saída (pós-vasectomia, trauma, c

5. Recombinant gonadotropin therapy to improve spermatogenesis in nonobstructive azoospermic patients – A proof of concept study
ABSTRACT Purpose: Nonobstructive azoospermia (NOA) associated with primary spermatogenic failure is a common cause of male infertility usually considered untreatable; however, some reports have suggested that hormonal stimulation to boost the intra-testicular testosterone level and spermatogenesis might increase the chance of achieving pregnancy using homol

6. Vasectomy re-reversal: effectiveness and parameters associated with its success
ABSTRACT Introduction: When the vasectomy reversal (VR) fails, and the patient desires natural conception with his sperm, vasectomy re-reversal (VRR) is the only alternative. Purpose: To determine the VRR effectiveness and whether specific parameters can be associated with its success. Materials and Methods: We retrospectively evaluated 18 consecutive vas

10. Determining an optimal cut-off value for follicle-stimulating hormone to predict microsurgical testicular sperm extraction outcome in patients with non-obstructive azoospermia
ABSTRACT Objective To determine the optimal cut-off value for follicle stimulating hormone (FSH) to predict the outcome of microsurgical testicular sperm extraction (micro-TESE) in patients with nonobstructive azoospermia (NOA). Subjects and methods We included a total number of 180 patients with NOA. The serum level of FSH was determined and all the sub

12. Pacientes com azoospermia e varicocele devem ser submetidos à cirurgia para recuperar a fertilidade?
Resumo Introdução: A varicocele é sabidamente uma das causas de infertilidade nos homens. A presença de veias espermáticas dilatadas pode criar um ambiente hostil para a espermatogênese. Isso é causa de baixa qualidade e quantidade da produção do esperma; em alguns casos, pode determinar uma ausência total de espermatozoides. O procedimento de var
