Abstract:
Testicular atrophy and testesterone insufficiency have been commonly reported associated with chronic liver diseases. Though testosterone dependent, the epididymal changes induced by liver disease have never been studied before. Thus, this study aimed to assess the ultrastructural events in the epididymis of rats with chronic obstructive jaundice. Chronic cholestasis induced many epididymal structural alterations manifested by the reduced tubular diameters, thickening of the tubular basement membrane, and regression of the principal cells. This was accompanied with reduction of principal cell organelles, cytoplasmic vacuolations, nuclear alterations, and stereovilli loss. The results establish that chronic cholestasis causes epididymal structural changes due to androgen deficiency.

Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...
