Testicular cell number estimation: To estimate the total number of spermatogonia A (pale-staining nucleus with a fine "dusty" distribution of heterochromatin throughout the nucleus), B (with dense clumps of heterochromatin around the periphery of the nucleus), (24) Sertoli cells, spermatocytes, round and long spermatids, and Leydig cells, a Nikon E200 light microscope (Tokyo, Japan) fitted with a 60x oil objective lens was applied at the final magnification of 1,640x.
The subcutaneous tissue consists largely of loose fibrous connective tissue containing interwoven smooth muscle cells, Leydig cells, and hemolymphatic vessels.
Well-differentiated SLCTs are benign and are typically easily recognizable by the presence of open Sertoli cell tubules and admixed clusters of Leydig cells in the intervening stroma (Figure 12, A).

In-depth study of gene expression revealed that a mechanism of transcriptional repression occurred in Sertoli cells and Leydig cells suppressing their endocrine capabilities and causing down regulation of testicular steroidogenesis.4 An increased trend in infertility cases has been reported in literature with 10-15% young couples affected in total out of which 50% of cases were attributed to male factor problems.5 Moreover, since ibuprofen is a commonly prescribed analgesic, there is a concern that women unaware of their pregnancy might overuse the drug in the first trimester.
