I have been on 5mg's of melatonin for five yeas now as an anti-age holistic. My sex life is the same as before taking it, no difference.
Melatonin is routinely taken by cancer patients at a rate of up to 80mg's (per day) an hour before bedtime, so an overdose would be difficult. We're talking bottles of it to even begin to cause a problem.... And experimental (unpublished) studies show that AIDS & cancer patients are taking 100's of MG's per day, but this is a strictly 'under a doctor's care' situation (not only would it be a prescription situation at that point but the patient is in a hospital bed).
At age 55, I take 20mg's per day an hour before bedtime, and see no side-effects at all, except for a few wild dreams (because the brain is more relaxed). There are studies done on mice that increased their life span by 25% by adding melatonin to their water bottles, and it was saturated in some mice to an equivalent of a human swallowing a melatonin pill the size of a house brick, and doing fine, so if you're into suicide, there are better ways.
In fact, I realize that the original question was probably a joke, because suidcial teens are given melatonin to lessen depression (they also get more sleep by taking it, as do colicky babies to get more sleep [usually at a rate of 0.3mg, but see a pediatrician first] which may reduce SIDS, plus not putting a fan directly on a sleeping infant as this triggers a gasping-to-exhaustion situation, putting them in stress and they later dream of when they were back in the womb when they did not breath [they autonomic system reverts back and they stop breathing]).
So if you are thinking of taking enough melatonin to kill yourself because you are depressed, you would not be able to do it, and in fact the joke would be on you because you would feel better than ever after taking it for a while, because by increasing the percentage of melatonin in your blood you would no longer want to kill yourself. Oops, try something else.
Colicky babies, depressed children, and ADAH situations can have a lower-than-normal producing pineal gland (which produces melatonin), so simply taking melatonin can raise the level and bring back an infant (from crying so much), wild child, teen, or ADAH situation without harmful 'drug the kid into a comma' type pills.

No. This is a myth. Masturbation does not lower your testosterone levels.
NO!.
Icing your testicles can temporarily lower testosterone levels because the cold temperature can slow down the production of testosterone in the testes.
There is no scientific evidence to suggest that wearing briefs lowers testosterone levels in men.
AS progesterone is for ladies and testosterone lare for men , so it should not affect each other.
Since those juices precede the actual orgasm, I assume they up the testosterone, if anything.
There is no scientific evidence to suggest that wearing underwear lowers testosterone levels. Testosterone levels are primarily influenced by genetics, age, and overall health.
Testosterone.
Herpes meds can actually lower testosterone levels which will not lead to a failed drug test. If you take testosterone to counteract the decline then you might fail a drug test for PEDs.
There is no scientific evidence to suggest that drinking water from plastic bottles lowers testosterone levels.
There is no scientific evidence to suggest that wearing polyester clothing lowers testosterone levels in men.
Wearing tight underwear can increase scrotal temperature, which may lower testosterone levels in men.
