Semen analysis

Semen analysis is used to diagnose male infertility. Freshly ejaculated semen is tested in a laboratory, and the number, shape and movement of sperm are measured. Semen quality can change between samples. Sometimes illness, fevers and infections can lower sperm quality so two semen analyses, six weeks apart, are needed to properly check fertility. Semen analysis is also used to confirm a successful vasectomy.
