Hypothesis text:

Considering a normal rate of once a day
Over a period of fifteen years
At an average volume of two millilitres
Per ejaculation

This being the basis for my hypothesis

I have expended eleven litres of sperm
On my fellow females
The number being irrelevant

I am still a single male without offspring
