848 testicular biopsy slides of 664 infertile men were reviewed from the archive of jahad daneshgahi pathology center. tite mean age of patients was 33 years. bilateral testicular biopsies were performed in 197 cases. in 47 cases (23.9%) the histopathologic findings were not identical mixed pattern were encountered frequently which must be kept in mirul in pathologic evaluations and reports.
This paper briefly describes recent data we have obtained on gonadotropin (GtH) regulation of the testicular somatic cells in relation to spermatogenesis and sperm production (spermiation). Throughout the spermatogenetic cycle, the number of testicular GtH binding sites was maximum before and during spermiation. While testicular sensitivity to s-GtH for 11 -ketotestosterone (11 1 KT) secretion ...
Sonography, a non-invasive, quick method without biological impact on the gonad, has greatly improved the diagnostic possibilities; it is the gold standard for the male genital system (gonads and genito-urinary tract) and in fact has oriented the prevention interventions [1]. It recognizes almost 100% of scrotal lesions and their solid, liquid or complex nature. It has allowed to overcome the l...
Diabetes-induced testicular cell death is due predominantly to oxidative stress. Nuclear factor (erythroid-derived 2)-like 2 (Nrf2) is an important transcription factor in controlling the antioxidative system and is inducible by sulforaphane (SFN). To test whether SFN prevents diabetes-induced testicular cell death, an insulin-defective stage of type 2 diabetes (IDS-T2DM) was induced in mice. T...
Human CMTM3 has been proposed as a putative tumor suppressor gene. The loss of CMTM3 has been found in several carcinomas. However, the regulation of CMTM3 expression and its function in tumor progression remain largely unknown. Here, we investigated the regulation of CMTM3 expression, function and molecular mechanism in human testicular cancer cells. CMTM3 was frequently downregulated or silen...
Spermatogenesis is a costly process that is expected to be under selection to maximise sperm quantity and quality. Testis size is often regarded as a proxy measure of sperm investment, implicitly overlooking the quantitative assessment of spermatogenesis. An enhanced understanding of testicular function, beyond testis size, may reveal further sexual traits involved in sperm quantity and quality...
