Mesonephric remnants have been rarely reported in the genitourinary system and sometimes impose a diagnostic challenge both clinically and pathologically. We reported a case of mesonephric remnant hyperplasia with mixed acinar/tubular and epididymis/vas deferens-like morphologies occurring in the renal parenchyma of a unilateral hypoplastic kidney, which has not been previously described.

Another point to consider is whether treatment of diabetes could have played a significant part in the aetiology of renal agenesis. The critical time for renal development is between 3 and 7 weeks, the somite stage to 18 mm size. During this time the mesonephros, mesonephric duct, metanephros and ureteric bud are in an active stage of development (Shikinami, 1926; Torrey, 1954). Hypoglycaemia h...

It was the aim of this study to characterize development gonads and genital ducts in equine fetus around time sexual differentiation. This included identification localization primordial germ cell population. Equine fetuses between 45 60 days gestation were evaluated using a combination micro-computed tomography scanning, immunohistochemistry, multiplex immunofluorescence. Fetal increased size ...

Gonads were removed from fetal mice at about the time that gonadal sex differentiation occurs. The gonads were cultured in vitro with or without their mesonephric tissue. When gonads and ducts removed from sexually undifferentiated fetuses were cultured together, the gonads of both sexes developed female characteristics, whereas gonads cultured without mesonephros developed according to the sex...

A 32-year old single man presented with azoospermia and low semen volume which was noted one and half a year ago. Transrectal ultrasonography and seminal vesiculography were performed to evaluate ejaculatory duct obstruction, and transurethral resection of the ejaculatory duct was performed using a hybrid technique of holmium:yttriumaluminium garnet laser with monopolar transurethral resection ...

Chicken CITED3 (cCITED3) is a novel gene, which is expressed in the pre-somitic mesoderm, the mesonephric tubules, the Wolffian ducts and collecting tubules of the developing urogenital system and in the cranial sensory ganglia. Sequence analysis revealed that cCITED3 encodes a protein which contains two conserved domains that have been described for members of the CITED family.
