Effect of melatonin and superior cervical ganglioectomy on luteinizing hormone on release induced by estradiol-progesterone in castrated rats
The effect of melatonin on luteinizing hormone (LH) release was studied in castrated female rats injected with estradiol and progesterone. Melatonin administered s.c. twice daily for 6 days exerted a biphasic. dose-related effect on LH release, the lowest dose (125 ó/100 g body weight) being stimula...
