Title: Possible alpha-adrenergic involvement in nicotine induced alteration of spermatogenesis in rat. Author: Patra PB, Sanyal S, Biswas NM. Journal: Andrologia; 1979; 11(4):273-8. PubMed ID: 227296. Abstract: Nicotine caused a fall in primary spermatocyte number together with a retardation of spermatocyte to spermatid conversions process. These effects of nicotine were possibly secondary to increased activity of adrenomedullary catecholamines, since the antispermatogenic effect of nicotine was prevented by phentolamine, a known blocker of catecholamine action at the alpha-receptor level.[Abstract] [Full Text] [Related] [New Search]
