OBJECTIVE The aim of this study was to present a rare congenital anomaly of polyorchidism and to review the current management. CLINICAL PRESENTATION AND INTERVENTION We report the case of a 19-year-old man who was referred for the treatment of an indirect left inguinal hernia. The ultrasound demonstrated a testis on the right side with an additional mass. The preoperative laboratory studies ...

Adrenogenital Syndrome, more properly defined as Congenital Adrenal Hyperplasia (CAH), is related to the enzyme 21-beta-hydroxylase deficiency, with impaired glucocorticoids and aldosterone syntheses and increased ACTH synthesis. This report describes a case of a monorchid patient suffering from Adrenogenital Syndrome and Leydig cell tumor of his testis. A right orchidectomy with implantation o...

PURPOSE Histological study of vascularization between a cecal pedicle flap and the testicle of Wistar rats. METHODS Fifty-three rats were studied. G1: submitted to celiotomy (a), mobilization of the right testicle (RT) to the abdomen (b), cecal flap suture to the RT (d) and cavity closure. G1: procedures a, b and d and fixation of RT into abdomen. G3: procedures a, b and d, exposition of RT t...

BACKGROUND Nanoparticles (Ag NPs) have recently received much attention for their possible applications in biotechnology and biomedical. However, little is known about the toxicity in reproductive organs of animal model following exposure to nanoparticles. OBJECTIVE This study therefore, tried to examine the effects of nanoparticles with a diameter range of 5-20 nm on the histology of the tes...

The underlying primary damage to the testis caused by chemotherapeutic regimens during childhood is largely unknown. Xenografting of monkey testes was successfully applied in maturation of juvenile testis to the point of complete spermatogenesis. This allows us to manipulate developing primate testis without direct treatment of patients. This new model is validated establishing the effects of c...

Prenatal events such as intrauterine growth restriction can affect gonadal development of the offspring and have an impact on reproductive health. To investigate the effects of intrauterine growth restriction induced by uterine artery ligation on the postnatal rat testis. Pregnant rats underwent uterine artery ligation at day 19 of gestation. Offspring were killed at 5, 20 and 40 days post-part...
