The numbers are dropping across the board in western society, regardless of race.

According to studies, white men actually have higher concentration, volume, and total sperm counts than Black men.


Semen Parameters in Fertile US Men: The Study for Future Families
Black men had significantly lower semen volume, sperm concentration and total motile sperm counts than White and Hispanic/Latino men.
We found significant differences in semen parameters among men of different race/ethnicity. Black men in our cohort had mean values for semen volume, sperm concentration, total sperm count and total motile sperm count that were significantly lower than White or Hispanic/Latino men. These differences did not appear to be attributable to study center. We are not aware of previous reports of differences in semen quality by race or ethnicity, and there appear to be few data regarding semen parameters in Black and Hispanic/Latino men. Povey et al, 2012 reported that Black ethnicity was a risk factor for low motile sperm concentration in a case-control study of male partners of infertile couples.


Modifiable and non-modifiable risk factors for poor semen quality: a case-referent study | Human Reproduction | Oxford Academic
The study identifies, using a case-referent analysis, demographic and social factors associated with low MSC in the male partners of couples presenting for fertility investigations. Only five factors were related to case status after adjustment for potential confounding factors, with men more likely to have low MSC if they had had a history of surgery to the testes; were of black ethnic origin or were in manual work (or not working at all).
Only five factors then remained significantly associated with MSC, namely ethnicity, testes surgery, previous conception, manual work and the wearing of boxer shorts. Table III shows the risk associated with each individual factor after adjustment for centre and the other four variables in the multivariable model. In this analysis men of black ethnicity remained more likely than Caucasian men to be a case
