OK, lets do some extreme calculations here...
365 days in a year.
A man needs 2.5 hours of rest to be ready for round 2, that's including 30 minutes to get the job done. (
FACT INFO)
Sleep is required, and they say you can survive on 6 hours though 8 is recommended. So...
24 hours - 6 hours of sleep = 18 hours of play
18 hours / 2.5 hours = 7.2 times a day but lets round to 7 to give the poor man an extra 30 min break
7 times a day, with 7 women = 7 possible pregnancies.
So...
365 days * 7 times a day = 2555
however, if we're repopulating the earth, don't forget to take into account leap year!
365.25 days * 7 days a day = 2556.75
So lets round to 2556 just for argument.
Now, not all will get pregnant for whatever reason, so lets use the good 80 / 20 rule.
80% * 2556 = 2044.8
So lets assume that means 2044 pregnancies.
Now, just in case, lets say only 80% come to term.
80% * 2044 = 1635.2
So we only have 1635 babies.
On average the typical male lives to be 75.37 years old. (75 for argument). (
FACT INFO)
So lets use the 80% rule because of hard horizontal labor.
75 years old * 80% = 60 years old.
The average male starts to be sexually active between 15 - 17, so lets say 16.
At 16 years old, if this male was to start the reproductive cycle we have 44 years of activity (60 - 16 = 44).
So 44 years of activity * 1635 babies / year = 71,940 children per lifetime.
Now, if all males but one were wiped out, and that one was 16 years old, and assuming there were enough women around to be able to keep him active he could keep this theory intact.
How many women per year would you need you ask?
2044 females per year, as above, but to keep him active you need twice that so that while one set is pregnant, the other is getting pregnant. So you need 4088 females to keep a male 100% active over the course of 2 years.
Ok, so, the common ratio for today, by doing some research, is 8 females to every 10 males born, so that's 10 males for every 18 children, and that's 8 females per every 18. So...
1635 babies per year * (10/18) = 908 males
1635 babies per year * (8/18) = 726 females.
Now, 80% again you will have 726 males and 581 females per year.
After 16 years of maturity these males can reproduce so after the 16th year, the production can increase exponentially.
When X > 15
15 years * 726 males = 10,890 males after 15 years
When X < 15
726 * ((726 new 16 year old males) * each new year) = A whole lot of people.
Any who, to conclude what I have to say is....
FIND SOMETHING BETTER TO DO ON YOUR SATURDAY THEN DO DAMN CALCULATIONS LIKE ME!
That is all.
