Abstract

Purpose: Our purpose was to determine the obstructed epididymal epithelium morphometric stare and to elucidate the influence of morphometric parameters on the fertilizing ability of aspirated spermatozoa. Methods: During MESA with IVF, epididymal tissue samples were carefully dissected, fixed, and prepared for morphometric analysis. The epitheliumof the three regions was studied: head, body, and tail (when present). The total area/luminal area ratio, epithelium thickness, and stereocilium length were measured. Results: We have found significant differences in the total area/luminal area ratio, epithelium thickness, and stereocilium length in obstructed epididymal length >4 versus 0.5-2 cm (P less than or equal to 0.01). Epithelium thickness and stereocilium length were significantly lower when no fertilization was observed in IVF. Conclusions: These results suggest that morphometric data of obstructed epididymis epithelium can be used as a means of explaining the failure of NF with epididymal spermatozoa.
