Effect of sexual steroid hormones and of clomiphene on the behavioral response to L-dopa in mice.

The scope of the present work was to ascertain the effects of some steroid hormones on the behavioral response of mice to L-Dopa. The drugs considered were: testosterone, mesterolone, cyproterone, estradiol, progesterone and clomiphene. The male sex steroids, having either androgen or antiandrogen properties, were able to potentiate the behavioral effect of L-Dopa in mice, while female sex steroids failed to demonstrate this activity. Clomiphene proved to be the most active in enhancing the behavioral effects of L-Dopa in mice.
