Antisperm antibodies aren’t common. Both men and women can make them. They can make it harder for couples to have a baby. But it's rare for antibodies by themselves ...
Which sperm will cause the foetus to be genetically male, “move faster but also die?
Y-sperm, which will cause the foetus to be genetically male, “move faster but also die faster” than X-sperm. It claims knowing this and having sex accordingly can influence what type of sperm cell will reach an egg cell, or ovum, and fertilise it.

Y-sperm were neither faster nor shorter-lived than X-sperm.
