According to the Guinness Book of World Records, the 18th century Moroccan ruler Ismail the Bloodthirsty
holds the record for being the most prolific father ever. He supposedly fathered 888 children, which means he had to father about 15 children a year for 60 years.
But Dorothy Einon, a researcher at University College London, argues in her article "How many children can one man have?"
that even if Ismail had access to a steady supply of fertile women, it would have been impossible for him to father this many children.
The infrequency of ovulation. Ismail would need to accurately time when the women were actually fertilizable, which is a fairly small window of time each month.
Women who mate infrequently have longer cycles and ovulate less frequently. So if there's this huge supply of women mating exclusively with Ismail the bloodthirsty, then each woman is mating infrequently, and thus the odds of mating when she's fertile become even slimmer.
The low incidence of conception. Even if Ismail managed to copulate with a woman at the ideal time, and an egg was fertilized, only 42% of fertilized eggs survive to the 12th day of pregnancy.
The high frequency of infertile women, especially in the developing world, which reduces Ismail's odds even more.
Not all women are chaste. It's not logical to assume that all those women were mating exclusively with Ismail. Therefore, one can't assume he was the father of them all.
If Ismail copulated with multiple women every day, his own sperm count would drop, further reducing his chances of impregnating a woman.
Einon concludes that, given all these problems "unless a man has an extensive harem and a good harem keeper, it is unlikely that the extreme range of male and female reproductive success is very different."
15 a year for 60 years
is only 1 and a quarter
pregnacies a month.
He had 550 wives (approx)
even if they ovulate less
I'll bet it still works out to
about once a month.
According to our logarithmic extrapolation of the fractal exponents, the answer is:
Discounts on V1agra!?!
Who's been using the Crays to go on Facebook?!?!
All Ismail needed was 13 wives like Mrs. Vassilyev. The 18th Century certainly was fecund.
The remarkable feature here isn't Ismail's productivity, it's the amazing supply of fertile women available to him.
Don't tell me he was able to escape the hazards of having sex with so many women. Not to mention the hazards of medical treatments of the time.
If I'm wrong and he had to pick up all these women in bars, I'll be really impressed.
No such thing. Go read some population genetics.
I suggest an alternate approach for any would-be record-thirsty Morroccans:
He fills up a glass a few times a day, at a leisurely pace...
the resulting fertilizer bottle is used by all women in his harem who suspect they might be in fruitful mood. In parallel.
That way he could reach dozens a day, repeatedly even.
They could dilute the milky treasure for easier handling.
He can still choose the old fashioned intercourse, of course, with whoever appeals as the seductress du jour.
By separating the pleasurable bit of friction from the dreary act of record building, he can tentuple his output and pleasure at the same time.
I bet there are numerous readers here who would volunteer to double check this theory in practice.
(count me out though, one woman is plenty 😊
Richard G. Gould, How many children could Moulay Ismail have had?, Evolution and Human Behavior, Volume 21, Issue 4, July 2000, Pages 295-296, ISSN 1090-5138, DOI: 10.1016/S1090-5138(00)00043-X.
The first error is to confuse the length of Ismail's reign with that of his life and grossly underestimating the number of years Ismail had the opportunity to keep a harem.
Secondly, Einon allows Ismail no further selectivity beyond avoiding sex with his women during their menses. Even so, the number of days the women could have been fertile should not be estimated at 3.5 of 23 (15.2%), but 6 out of 23 days (26%), because sperm actually can survive that long on average.
Moreover, Einon relied on studies of the percentage of menstrual cycles that are ovulatory which also include much older women (as well as women who were breastfeeding) than those in Ismail's harem, who were retired on full pension at age 30.
Thus Ismail would need not 2.9 but just over 1.2 couplings per day in order to father 888 children, which is well within the two fertile ejaculations per day which Einon herself suggests that a man might sustain.
Gould concludes that "Einon's thesis that Ismail could not have fathered the 888 children attributed to him must be awarded the traditional Scottish verdict 'not proven.'" -- and I suggest you change the status to that rather than "Highly unlikely."
If you can supply more than enough women for me to have sex to, then for sure I can keep them pregnant for sure.
If you can supply 1000 women... I can produce more than what this fella done if I have sex two times a day... hahaha
