Testicular Biopsy Score Count After Vasectomy in Albino Rats

Context: One of the challenging problems faced by the entire world is population explosion. The vasectomy is simple, safe, quick and effective vital method of male sterilization. In the recent years a large number of vasectomies have been performed in India, since the inception of National Family Planning Program in 1956. Thus the number of request for the restoration of fertility is also increased. Aim: The present study was carried out to know whether the testicular biopsy score count, indicating the process of spermatogenesis remains normal after vasectomy. Material & Methods: The testicular biopsy count of testes of 50 male albino rats was studied one, two, three and four months after vasectomy, in 10 male albino rats of each case and 10 male albino rats served as control. Result: After vasectomy seminiferous tubules are cut in various planes covered externally by connective tissue stroma with normal microscopic picture. The spermatogonia, spermatocytes, spermatids, Sertoli cells and spermatozoa show normal structure with normal size blood vessels in interstitial connective tissue, in vasectomised and control rats. In some seminiferous tubules granular cytoplasmic vesicle like structures are seen filling the lumen and spermatids in metamorphosis phase to spermatozoa. Many round or elongated heads of spermatozoa are present at apical portion of Sertoli cells. The control rats as well as vasectomised rats at four after vasectomy have shown the testicular biopsy score count of nine (9) and ten (10) on TBSC of Johenson. Conclusion: On critical analysis it is concluded that the testicular biopsy score count remains normal at four months after vasectomy.
