Abstract:
The effects of methallibure (0.3 mg/g body weight) were studied in adult, gravid roach during the spawning season. The treatment stopped the normal process of spermiation and ovulation. In testes, mature sprems were reabsorbed and the mitotic division of primary spermatogonia restarted. In ovaries, all the mature oogonia was unaffected. Methallibure treatment also inhibited the synthesis and release of gonadotropic hormone from the PAS positive cyanophils of the pituitary gland. As a result of this treatment gonadal ascorbic acid was significantly reduced. This reduction of ascorbic acid level indicates the inhibition of gonadal steroidogenesis.
