WebMD: Bright Light May Boost Testosterone

Interesting article, short read.

April 22, 2003 -- Waking up to bright light may trigger a rise in male hormones that could ease sexual dysfunction and other symptoms of depression. A new shows that early morning light therapy caused a surge in a pituitary hormone called luteinizing hormone (LH) that raises testosterone levels in men. (more...

Thanks.

Won't be long before we see this in tanning booth brochures . . .

WHERE DO I BUY THIS SPECIFICALLY DESIGNED LIGHTBOX?

Damn 70% rise in LH. Seems better than Clomid !

bright light boosts test?


so does a shinny 22g 1.5inch load with 3cc of suspension

Maybe increased melatonin increases test levels? Junk, you may have something there...

Abstract: Subcutaneous melatonin implants were inserted in mink subjected to natural (autumn) or experimental gonadostimulatory short-days (4L:20D), after lesion of the suprachiasmatic nucleus (SCNx) or after superior cervical ganglionectomy (SCGx). Gonad stimulation was assessed by measuring testicular volume and plasma testosterone level. In SCNx and SCGx animals, all measurements were indicative of sexual quiescence. In contrast, both SCNx and SCGx animals with melatonin, maintained in natural or experimental gonadostimulating short-days, showed an increase in testicular activity 2 months after melatonin implantation. Thus, melatonin (and pineal activity) is a prerequisite for the photoperiodic stimulation of reproductive activity, and the SCN is not necessarily the target site for melatonin action on the renewal of reproduction in the mink.


There were a few of these studies done on various animals, but i can't find any about humans...I'll keep looking though.

Abstract: The role of melatonin in the regulation of human reproduction remains unclear. In the present study, we examined the influence of exogenous melatonin on pulsatile luteinizing hormone (LH), diurnal rhythm of testosterone, and endogenous melatonin profile in six healthy young adult males. To test the hypothesis that the effect of melatonin on LH or testosterone secretory patterns may be mediated through the benzodiazepine-(BNZ) gamma-amino-butyric acid (GABA) receptor complex, a benzodiazepine receptor antagonist (Flumazenil) was administered. The study design comprised four 10-h (4:00 PM-2:00 AM) testing periods. During each experimental period, subjects were given an oral dose of placebo, or 3 mg melatonin or 10 mg flumazenil, at 5:00 PM, in a randomized, double-blind, partially repeated Latin square design in the following combinations: placebo-placebo, placebo-melatonin, flumazenil-placebo, and flumazenil-melatonin. The following day, serum samples were obtained every 20 min between 4:00 PM and 2:00 AM in a controlled light-dark environment for the determination of LH and melatonin levels. Serum testosterone concentrations were determined every 20 min between 7:00 and 8:00 AM and 7:00 and 8:00 PM. A significant decrease in mean serum LH levels (p < 0.02) was observed in the melatonin-treated groups as compared with placebo-flumazenil groups. There was no change in LH pulse frequency, testosterone levels, or in melatonin onset time and amplitude. No additional effect of flumazenil on LH or testosterone levels was observed. These data indicate that an evening melatonin administration decreases the next-day LH secretion in normal adult males without altering testosterone levels or the endogenous nocturnal melatonin secretory pattern. This effect of melatonin is not mediated through the benzodiazepine-GABA receptor complex.

I am 36 years old and bright lights have yet to give me a bonner.

That's probably because it doesn't work on women.

LOL!! Just kiddin bro...
