Abstract
Histological and histochemical studies were made on testes along with epididymis, seminal vesicles, prostate (Pars-disseminata) and bulbo-urethral glands of normal and vasectomised Black Bengal goats. Animals were divided into 3 groups: 3 months after vasectomy (Group I); 6 months after vasectomy (Group II) and 12 months and above after vasectomy (Group III). Each group consisted of 3 vasectomised and 3 normal goats.
Testes: The testes enveloped by a capsule comprised of inner tunica albuginea and outer tunica vaginalis. The interstitial cells were present at the inter tubular region. The testicular parenchyma consisted of seminiferous tubules. The spermatogenic cells were present in several layers and Sertoli cells were placed basally in between the spermatogonia. Mature sperms lied over indistinct Sertoli cells.
After 3 months of vasectomy, diameter of the seminiferous tubules were reduced significantly (P 0.01). Spermatogenesis was increased as evidenced by the significant increase of the thickness of stratified epithelium. Some Leydig cells showed hypertrophy and hyperplasia.
After 6 months of vasectomy, spermatogenesis was increased highly but a few tubules showed desquamation of primary spermatocytes and spermatids into the lumen.
