Effect of pinealectomy on the photoperiodic gonadal response of the Indian garden lizard, Calotes versicolor

Abstract

Pinealectomy during early summer partially, but significantly, inhibits the decrease in the gonad size of lizards subjected to short photoperiods. During early winter, it significantly accelerates the growth of the testes in animals subjected to constant long photoperiods. It is proposed that the pineal, as in mammals and some birds, probably acts by way of the neuroendocrine complex. © 1979.
