Abstract
Experiments were performed in male rats to study the influence of lindane on the activities of hypothalamic and pituitary enzymic systems (5α-R, 3α- and 17β-HSD) involved in testosterone metabolism. Lindane at a concentration of 0.17 .... 0.51 µmoI significantly inhibited the activity of 5α-R (up to 48%), 3α-HSD (up to 41%) and 17β-HSD (up to 29%) in the anterior pituitary. At hypothalamic level the same concentrations of lindane inhibited 5α-R activity (up to 39%), while 3α- and 17β-HSD activities were not affected. The ability of lindane to inhibit the 5α-R, 3α- and 17β-HSD activities at neuroendocrine level suggest that its constant presence at a concentration likely to be found in the organism could have an impact on the reproductive system.
