Can you get pregnant with sperm antibodies?

High levels of antisperm antibodies make it more difficult for sperm to fertilize an egg. While high levels of antibodies can make it difficult for a couple to get pregnant, there is hope.

What race has the highest sperm count?

Whites had higher semen volumes than Asians (2.9 mL vs. 2.6 mL; p = 0.001), while Asian males had higher sperm concentrations (60.9 million/mL vs. 51.3 million/mL; p <0.0001, Table 2). Asians tended to have a higher average total sperm count compared to White males, but a lower total motile sperm count.
