Many people have claimed positive outcomes when using melatonin for inducing sleep. Melatonin is a substance that your brain's pineal gland secretes, producing the effect of sleepiness. It has been used as a supplement for those who work irregular hours and by some recovering from jet lag. While the effects of melatonin can be beneficial for sleep cycles, it has many side effects that influence various body systems.
Melatonin produces side effects in men that affect reproductive functions. It has been shown to decrease the amount of sperm in men and affect sperm motility, according to the Mayo Clinic. These side effects disrupt reproduction as lower numbers of sperm decrease the chance of conception. Slow motility affects how sperm swim, preventing them from reaching an egg for fertilization.
Melatonin may produce side effects that affect hormone levels in women, including changes in the levels of progesterone, estradiol, luteinizing hormone and thyroid levels. The Mayo Clinic reports that alterations in the levels of these hormones affect the process of ovulation and menstruation, which can cause problems with conceiving or maintaining a pregnancy.

Answer:
It appears that the function of melatonin is to mediate dark signals and provide night information, a “hormone of darkness,” rather than be the hormone of sleep. It has also been thought to be an “endogenous synchronizer” that stabilizes and reinforces various circadian rhythms in the body.Jul 9, 2012
