females do not produce sperm
Artificial insemination (AI) is the process by which sperm is placed into the reproductive tract of a female for the purpose of impregnating the female by using means other than sexual intercourse. In humans, it is used as assisted reproductive technology, primarily to treat infertility using sperm from the woman's partner, or sperm from a sperm donor (donor sperm) where the male partner produces no sperm. It is also increasingly used to enable women without a male partner (i.e., single women and lesbians) to produce children by using donor sperm. In cases where donor sperm is used the woman is the gestational and genetic mother of the child produced, and the sperm donor is the genetic or biological father of the child.
There is no race in the sense of a competition, all sperm are equally affected by the chemical signals. When the sperm reaches the egg, its tail is cast off; thus disposing of male mitochondrial material; and the egg is immediately changed by the entry of the sperm so that another sperm cannot enter. Then follows the joining of the two DNA strands etc.
