asthenospermia

Asthenospermia is the medical term for a condition in which a male’s sperm have reduced motility (the ability to swim or move). Genetic, idiopathic, and iatrogenic factors can result in this condition. Although male infertility is most commonly attributed to a low sperm count, having sperm with poor motility can lead to infertility, as well, because, once ejaculated, the sperm must be able to travel through the vagina, cervix, and uterus before reaching the fallopian tubes where fertilization will take place. To overcome infertility due to asthenospermia, assisted reproductive technology procedures can be utilized, such as intracytoplasmic sperm injection.
