Different olfactory system deficits affect the antigonadal action of light deprivation differently in male rats.
Twenty-eight day-old male rats were subjected to: Blinding-olfactory bulbectomy, Blinding-peripheral anosmia, Blinding-accessory olfactory bulbectomy and Blinding-sham olfactory operation. A set of rats remained intact. Six weeks later, their pituitary-gonads-accessory sex organs were studied. Bulbectomy as well as peripheral anosmia exaggerated the antigonadal effects of blindness, while the accessory olfactory system impairment did not. It is suggested that olfactory bulbectomy potentiation of the antigonadal effects of light deprivation is due to a lack of sensory function rather than to bulbectomy itself and that the accessory olfactory system which is involved in the priming pheromonal effects does not play any role in the inhibition of the antigonadal effects of blindness.
