Estimation of the testicular levels of follicle\u2010stimulating hormone, luteinizing hormone and prolactin \u2032(PRL) in the zinc\u2010deficient (ZD) rats showed higher levels in comparison with both control and zinc\u2010supplemented rats. However, the increase in PRL levels was statistically insignificant. A great reduction in the activity of 3\u03b2\u2010hydroxysteroid dehydrogenase, an important enzyme involved in testosterone biosynthesis, was demonstrated histochemically in the testes of ZD rats as compared to both control and ZS ones. These results reflect a direct action of zinc deficiency on the testicular steroidogenesis and strongly support the idea that the hypogonadal state associated with zinc deficiency results mainly from some alteration in the testicular steroidogenesis or in other words LEYDIG cell failure.<\/jats:p>","DOI":"10.1002\/food.19890331010","type":"journal-article","created":{"date-parts":[[2006,11,3]],"date-time":"2006-11-03T03:08:53Z","timestamp":1162523333000},"page":"941-947","source":"Crossref","is-referenced-by-count":10,"title":["Role of zinc in regulating the testicular function.
