The number of
possible persons is determined by combining the current world supply
of ova with the world supply of sperm.

person
= combination of specific ovum and sperm 

current
population = 6240272424 persons 





average age
of puberty (menarche) in female = 12.8 years
average age of menopause in female = 50.5 years
average number of years female releases ova = 37.7 years
ova released by female per year = 13.04 ova per year
average number of ova released over lifetime
of female = 491.77 ova
average number of ova produced over lifetime of female (a) = 400000
ova
current population of females 15 to 65 years old = 1898479062
current population of females 12.8 to 50.5 years old capable of
reproduction (f) = 1431453213
number of ova available from current population (a x f) = 572581285100000
ova



average age
of puberty in male = 12.5 years
average age of male menopause = 55 years
average number of years male produces sperm = 42.5 years
average number of sperm cells per ejaculate = 400000000 sperm
average number of ejaculates per year from 15 year old male = 152.08
average number of ejaculates per year from 55 year old male = 43.5
average number of ejaculates per year during fertile life of male
= 97.79
average number of sperm ejaculated during fertile life of male =
39116666667 sperm per year
average number of sperm ejaculated over
lifetime of male (b) = 1662458333300 sperm
current number of males 1565 years old = 1942402264
current number of males 12.5 to 55 years old capable of reproduction
(m) = 1651041924
number of sperm available from current population (b x m) = 2744788405899999838208



number of ova
needed to create person = 1 ovum
number of sperm required to create person = 1 sperm
1 ovum + 1 sperm = c = 2
available supply of ova = v = 572581285100000
ova
available supply of sperm > available supply of ova
