Volume of Ejaculate as Men Age

Factual Questions
1

In this thread, someone stated (probably in jest) that adolescent males deliver more ejaculate per orgasm, the premise being that we produce less and less (per “shot,” so to speak) as we age.

Is this true?

Note that I’m speaking about the volume of ejaculate, and not the number of sperm.

Think about it. If that were true, 80yo men would be in high demand for porn money shots.

3

I think there may be some other considerations in casting that simply ejaculate volume…

4

Cause when it comes to parties, younger men are lemons.

Then how can you explain Peter North?

Wait, what? Why would older men be in greater demand if the volume of their semen is less? I thought those who like money shots like, well, rich money shots?

Anyway, yes, it’s true. Volume does decrease with age, about 0.03 ml per year of age after age 22 (tested to age 80), for healthy, non-smoking males. http://humrep.oxfordjournals.org/content/18/2/447.full

Why? Partly normal aging causing prostate changes, partly because fat stores/creates excess estrogen which messes with testosterone, and men tend to become more rotund of tum with age.
