Study of Thyroid gland treated with Oxytocin in relation to the reproduction in the fish Cyprinus carpio.
Keywords:
Estrogen, Neurohypophysial hpomone Oxytocin, spawning reflexesAbstract
Oxytocin is neurohypophysial hormone primarily stimulates the uterine contractions during labour and release of breast milk. This hormone also plays a role in mating behavior and sexual response. In the present study, oxytocin was injected 1.5ml/kg body weight once in a week for four weeks in the fish, Cyprinus carpio. It has been observed that oxytocin stimulates the sexual behavior leading into breeding. Histological studies showed that oxytocin stimulate the estrogen secretion in the female and increased the number of follicular cells. Thus it had been concluded that thyroid gland treated with oxytocin is associated with induction of spawning reflexes in the fish Cyprinus carpio.
