Epididymo-testicular descent

Insulin 3-like hormone and its role in epididymo-testicular descent.

PURPOSE The role of insulin 3-like (Insl3) hormone signaling in the testicular descent process has been demonstrated. The purpose of the present study was to evaluate epididymal development in Insl3-deficient mice. MATERIALS AND METHODS Heterozygous and homozygous Insl3 mutants of a mixed CD1 X 129/Sv genetic background were generated by breeding Insl3-/- females with Insl3+/- males, and thei...

On the descent of the epididymo-testicular unit, cryptorchidism, and prevention of infertility

This comprehensive review provides in-depth coverage of progress made in understanding the molecular mechanisms underlying cryptorchidism, a frequent pathology first described in about 1786 by John Hunter. The first part focuses on the physiology, embryology, and histology of epididymo-testicular descent. In the last 20 years epididymo-testicular descent has become the victim of schematic drawi...

Tuberculous epididymo-orchitis mimicking a testicular tumour: a case report.

INTRODUCTION Isolated tuberculous epididymo-orchitis may closely mimic testicular tumour particularly in patients with no history of systemic TB thereby presenting a diagnostic and treatment challenges. CASE REPORT A 44-year old man presented with 4 months history of left scrotal mass and had left orchidectomy following a presumptive diagnosis of testicular tumour. Histopathological diagnosis...
