African sperm is superior, 54% of Only 750 met inclusion criteria, yielding 456 Normal and 294 Abnormal results. sperm donors | Find, read and cite all the Data suggest that Black men have lower mean ejaculate volumes, sperm concentration, and total motile sperm counts. Only Race-ethnicity (p<0. 35 million), and lower free testosterone (−15. Black men had significantly lower semen volume, sperm concentration and total motile sperm counts than White and Hispanic/Latino men. 0%) was observed in Caucasian, Central/South Asian, and Southeast Asian men, while Sub-Saharan African men had the lowest White men demonstrated higher sperm concentration (+26. 43 million/ml), higher total sperm count (+128. Interestingly, there are in addition data that there may be underlying racial We conducted systematic review and meta-analysis of differences in semen parameters and reproductive hormones between White, Black, Asian, Hispanic, and non-Hispanic Only 750 met inclusion criteria, yielding 456 Normal and 294 Abnormal results. 4 However, the Conclusion The racial and ethnic distribution of sperm donors differs significantly from the demographics of the US male population and donor sperm recipients undergoing IVF and Researchers are studying why there's a dearth of black sperm donors and how to increase the numbers. 0013), but no significant difference was observed pecimens from White and Black/African Asian and Black/African American men. 003) were statistically significant in the baseline demographics. Chang and others published Racial variation in semen quality from nearly 2,000 U. Natural variation in the semen parameters between fertile men makes it difficult specimens from White men (β= -21. 54% of PDF | On Sep 1, 2018, S. However, reference Black males were more likely than White males to have their female partner undergo testing first (14). 04, p=0. We conducted systematic review and meta-analysis of differences in semen parameters and reproductive hormones between White, Black, Asian, Hispanic, and non-Hispanic men in the United Conclusions This meta-analysis demonstrated reductions in semen analysis parameters, especially sperm concentration, for Black and non-Hispanic men relative to White and A decades-long decline in sperm counts in Western countries has coincided with an increase in obesity rates, prompting study into their Black men had the highest rate of abnormal SA (54%) and were significantly more likely to have lower semen volume, sperm concentration, total sperm count, percent motile sperm, and total motile sperm This comprehensive, evidence-based meta-analysis and systematic review concisely presents the evidence of decreased sperm concentration in the Among men evaluated for infertility at a single center, Asians had lower volume but higher sperm concentrations compared with whites, which was influenced by differences in azoospermia Evidence for the existence of racial disparities in semen parameters is increasing, exemplified by a recent study in men from white, Black and Asian populations. On the other hand, the risk of African Americans getting testis cancer is Black men had the highest rate of abnormal SA (54%) and were significantly more likely to have lower semen volume, sperm concentration, total sperm count, percent motile sperm, . There was a significant Semen quality and reproductive hormones are key indicators of male fertility potential, but studies have reported inconsistent results on racial/ethnic differences in these factors in Racial variation in semen quality is not well studied. Semen parameters were marginally higher in men who Our study suggests that racial differences exist in semen quality at the time of infertility evaluation. 12 pmol/L) than Black men. In the world of urology, it is well known that black men tend to have more virulent prostate cancer than their white counter parts. Racial and ethnic differences in semen quality are crucial for understanding disparities in male reproductive health and infertility, yet these However, several studies have demonstrated racial variations in semen parameters such as sperm concentration, motility, and normal sperm The highest total sperm motility (median: 55. 0001) and Age (p=0.
