Male infertility is known to be associated with testicular tumors (Honig et al, 1994). In one recent report (Nobert and Goldstein, 2001), at least a 16-fold increase in the risk of testicular cancer, with seminoma being the most prevalent one, has been reported to be associated with male infertility. Generally, the standard initial treatment for testicular mass, in view of its high likelihood o...

The pineal hormone melatonin regulates testicular function through the hypothalamic-adenohypophyseal axis. In addition, direct actions of melatonin in somatic cells of the testis have been described. Melatonin acts as a local modulator of the endocrine activity in Leydig cells. In Sertoli cells, melatonin influences cellular growth, proliferation, energy metabolism and the oxidation state, and ...

testosterone is believed to play a significant role in spermatogenesis, but its contribution to the process of spermatogenesis is not completely understood. given that extracellular matrix (ecm) facilitates differentiation of spermatogonial stem cells (sscs) during culture, the present study was conducted to elucidate whether testosterone contribute to the permissive effect of ecm on sscs diffe...
