In the competitive binding assay, procymidone showed a significant but lower binding affinity comparing to that of cyproterone acetate, the steroidal androgen receptor antagonist, for the androgen receptor in both rats and mice under the condition that unlabeled dihydrotestosterone (DHT) effectively inhibited the binding of [3H]-DHT to the androgen receptor in both species.

In vitro both vinclozolin and procymidone significantly inhibited the binding of agonist to the androgen receptor with the concentration that resulted in 50% inhibition (IC (50)) values of 0.1 and 0.6 micro M, respectively.

The possible mechanism of ICT production in rats by non-genotoxic procymidone, structurally similar to flutamide, a synthetic non-steroidal antiandrogen, is likely to be derived from its induction of a hypergonadotropism due to the competitive binding to the androgen receptor, preventing the normal effect of testosterone to control the circulating level of LH.
