An essential feature of GCNIS, perhaps previously less emphasized than it should have been, is its requisite location at the base of seminiferous tubules in what has been termed the spermatogonial niche (Figure 1, A).
Tubules and interstitial tissue volume evaluation: The point counting method was applied to estimate the volume density and volume of the seminiferous tubules and interstitial tissue at the final magnification of 280x:
Spermatogenesis was assessed by a method which depends upon scoring 'cross sectional' profiles of seminiferous tubules according to Johnson, using Johnson's score.
In the control group, the rat testes showed normal morphology and spermatogenesis, healthy seminiferous tubules containing plenty of spermatids and sperm in the lumen (Figure 1).
For morphometric analysis, 15 seminiferous tubules from each goat were photographed under microscopy with a 10x objective, after which the photomicrographs were used to measure the tubular diameter by means of ImagLab 3000 software.

This study evaluates the reversibility of KISS1 gene vaccine for immunocastration in ram lambs in terms of changes in anti-KISS1 antibody titers, serum testosterone levels, scrotal circumference, testicle weight, and spermatogenesis in the seminiferous tubules. The safety of immunocastration against KISS1 gene vaccine was evaluated in terms of the integration of fusion gene KS (KISS1- HBsAg-S, HBsAg-S refers to hepatitis B surface antigen S) of KISS1 gene vaccine and genomic DNA of the host cell in vaccinated ram lambs.
The European Guidelines on male infertility recommend Johnsen's scoring for the assessment of the stage of spermatogenesis in the seminiferous tubules (6).
The tubular compartments were comprised of the seminiferous tubules, straight seminiferous tubules and rete testis, without any distinct boundary tissue between them.
Three stages were present: (1) Regressed, seminiferous tubules contained mainly spermatogonia and interspersed Sertoli cells; (2) Recrudescent, germ cell proliferation for the next period of sperm formation (spermiogenesis) had commenced.
Spermatogenesis occurs in seminiferous tubules of testis, a unique site that contains three types of cells: male germ cells, Sertoli cells, and myoid cells [6].
