Why do white and Latino men have more bigger testicles and and more sperm than black men?

https://onlinelibrary.wiley.com/doi/10.1111/j.2047-2927.2013.00125.x/abstract

he Study for Future Families (SFF) recruited men who were partners of pregnant women attending prenatal clinics in Los Angeles CA, Minneapolis MN, Columbia MO, New York City NY and Iowa City IA. Semen samples were collected on site from 763 men (73% White, 15% Hispanic/Latino, 7% Black and 5% Asian or other ethnic group) using strict quality control and well-defined protocols. [. . .] Black men had significantly lower semen volume, sperm concentration and total motile sperm counts than White and Hispanic/Latino men.

This is consistent with the other evidence I'm aware of. Lower sperm counts have been noted in Africa, and a study in Rochester, NY, that included a small number of American blacks similarly found:

All sperm parameters were significantly lower in the small subgroup (n = 7) of African-American men compared with other men in this population (p-values for sperm parameters, < 0.001 to 0.016).

Also consistent with these results: the only autopsy studies I'm aware of (at least one of which Rushton knew of before he became selectively forgetful) both suggest black men have smaller/lighter testes than white men.

  • i'm shocked this study got published
    only 763 couples
    557 white
    113 latino
    57 black
    seems like a really small sample.
    ... and then this "Race/ethnicity varied by centre with most Hispanic/Latino men in CA and Black subjects mainly in CA and MO, whereas participants from MN, NY and IA were predominantly White."
    seems to show that evironmental factors could play a massive role in results

    nonetheless i'd say it probably has to do a lot with lifestyle factors. factors like amount of exposure to sex, drugs, alcohol, good eating habits, good exercise habits

  • Yeah I do have big balls, lol but this is news to me, I can tell you from experience I got my ex pregnant right away everytime but I also heard black men have faster sperm though

  • I think that testicle size and sperm count is mainly related to the promiscuity of the females. Gorilla’s have small testicles and lower sperm counts then men because their female partners don’t shop around for DNA.

    White men need to supply more sperm and semen to make sure it’s their DNA that’s transferred down and someone’s other.

  • The fact that most political systems suggest that we should strive for equal rights among the races does not mean that all races are equal (in the sense of being identical.) Unfortunately, political correctness quashes much of this discussion.

    • so because one race has larger testicles means we shouldn't strive for equal rights? huh

    • @madhatters4 I don't know how you got that idea out of the words that I said. That is NOT what I said and not what I meant. If you are looking for someone to hang just to prove that you are on the right side of political correctness, please look elsewhere.

    • sorry if i misread. i was not looking for anything but perhaps just misinterpreted your point. i thought you were saying that political corrected-ness somehow squashes discussion regarding races being equal and tying that into the quest for equal rights

  • The way you live actually have a fairly big impact on your sperm count etc.. so since black men often are poorer they are more exposed to unhealthy lifestyles and this is one of the results. I believe if you made the test between people with similar lifestyles there would be little to no difference.

  • Well it was a small group. It could be contributed to diet/drugs use. Smoking lowers counts, steroids, etc.

  • Because they are less likely to reproduce

  • I'm just gonna put this one out there to start a fire and walk away.

    What some men will miss in testicles size and sperm count, they will compensate in bigger dick size.

  • Lol... just... lol... well... if you think so... then explain those high hit counts on pornhub for Ebony, Black & Interracial... eh? EEEEEEEEEEEEH? :v
    An I wonder if they went looking for the smaller black guys just so they look good. :v

    Lol but I have to admit... nice bait tho mate... I rate 8.8... too bad tho cuz I already ate... so you a little late. XD

  • what u like more sperm or less?


  • It’s just a difference in evolutionary trade-offs. Take Asians vs. Europeans. Although it seems this study didn’t include Asian men, it has been reported that Asians do have smaller testicles but developed bigger brains, while Europeans developed bigger testicles but did not increase in cranial capacity.


    Of course, in our increasingly globalized world it’s easy to see that a bigger brain is favored over a bigger nutsack. Many high paying jobs require high IQs, and Asians are at the forefront. In fact, in the US, Asian men earn more money than white men (and recently Asian women out-earn white men). This goes to show that Asians can and have been outperforming whites with regard to educational attainment and income. Of course, large brains also afford Asians with big motor cortex: Asians have better agility, balance and eye-hand coordination then many whites, and various Olympic sports, for example, are dominated by Asians because of their agility, speed and strategy and discipline. In these instances, white athletes that once did well at that sport now struggle to compete as more Asians join. Even traditionally European or “white people” sports are getting dominated by Asians, such as fencing and snowboarding.


    While white men struggle to compete with Asian men’s intellect and athleticism, they fair much better in the reproductive department, particularly with regard to the size of the testicles. Yes, Asian men have much smaller testicles (and penises) than white men, and as a result Asian men produce less sperm and testosterone than white men. However smaller testicles have their benefits: they are correlated with monogamy and good child-rearing behaviors — Asians are known to stay in longer relationships and be good parents. And larger testicles have their negatives: they are associated with increased aggression (big balls —> more testosterone —> more aggression) — and it seems like Asian men are substantially less aggressive compared to white men (just watch the news lol). Men with large balls are also at higher risk of cardiovascular disease among other heath issues. Interestingly, young adult white men are the most likely to develop testicular cancer (about 3x more likely than Asian men), no surprise considering the large size of a white mans testicles.


    All in all, whites will be increasingly overshadowed by Asian excellence, and white men in particular will have difficulty competing with Asian men. It’s a true brain vs brawn scenario: the Asian’s big brain vs the White man’s big hairy balls. I think the outcome is a no-brainer lol.


    P. S. let’s not forget that testicles are sensitive and vulnerable organs. It goes without saying that a white man’s big testicles are more likely to get injured day-to-day compared to an Asian man’s smaller testes. Large nuts are also perfect targets in self defense!

  • Another one of those annoying racial based studies.. gad !

  • Probably they have different diet
