Which condition refers to the fertility issue where sperm motility is impaired?

The condition that specifically refers to impaired sperm motility is diminished sperm motility. This term describes a situation where the sperm cells do not swim efficiently or effectively, which can significantly reduce the chances of conception since motility is crucial for sperm to reach and fertilize the egg. Sperm must be able to maneuver through the female reproductive tract to reach the ovum, and any impairment in this ability can contribute to fertility challenges.

Unexplained infertility refers to cases where no identifiable cause for fertility issues is found, which may or may not involve sperm motility as a factor. Unsuccessful vasectomy reversal relates to complications following a surgical procedure aimed at restoring fertility, but it does not specifically address sperm motility issues. Endometriosis is a condition affecting the lining of the uterus and can impact fertility by creating a challenging reproductive environment, but it does not directly refer to sperm motility.
