Effect of injecting 5-methoxy indoles, pineal compounds, on testicular weight of white leghorn cockerels (Gallus domesticus L.). 1977

M G Balemans, and F C van de Veerdonk, and J C van de Kamer

White leghorn cockerels of the same age with combs of about equal size and raised under identical conditions were injected with melatonin, 5-methoxytryptophol, or with 5-methoxytryptophol in combination with melatonin. Melatonin, injected in animals with small comb sizes, has no effect on testicular growth, whereas an inhibiting effect is noticed in animals with larger comb sizes. The 5-methoxytryptophol treated animals demonstrated stimulated testicular growth, which can be interpreted as an acceleration of the rhythm of growth. The stimulatory effect on testicular growth is more distinct if 5-methoxytryptophol is injected in combination with melatonin.

D007211	Indoles	Benzopyrroles with the nitrogen at the number one carbon adjacent to the benzyl portion, in contrast to ISOINDOLES which have the nitrogen away from the six-membered ring.

D008550	Melatonin	A biogenic amine that is found in animals and plants. In mammals, melatonin is produced by the PINEAL GLAND. Its secretion increases in darkness and decreases during exposure to light. Melatonin is implicated in the regulation of SLEEP, mood, and REPRODUCTION. Melatonin is also an effective antioxidant.
