a male molts into a MM and then makes a spermweb.......and every time after mating they have to make a new sperm web to "load"......(A)does the amount of times a male gets mated reduce their life expectancy? and ( exept for life xpectancy can the number of times a male has been mated deplete him? ie: a male has been mated with 5 females but is only 5 months old....is he still good to go?

...there where the smile is should actually be a (b)

Don't think anyone has done any research on the subject, so very hard to say.
Personally though, i prefer to use the males as soon as possible.

But as a guess.

A ) Shouldn't reduce his life expectancy unless the female makes a meal out of him.
B ) He should still be good to go no matter how many times he mates. Don't think it will affect him as much as ageing will.

Hey!

Another thing is that a male doesnt have to make another sperm web after matting!( like the OP says) He only has to replace his surplis if its all used! (they dont always use all in a single mate)

Does alot of matting shorten their life span- ide say no! (as long as the mattings went smooth)
