What it is: A test of the sperm in a man’s ejaculate. The semen analysis tells us the concentration of sperm, how many are moving, how fast they are moving forward, and how many have a normal appearance.
How it helps: Just because a man’s ejaculate appears normal does not mean he is fertile. 30–40% of infertility cases are caused by problems with the man’s semen. Fertile men typically have over 20 million swimming (“motile”) sperm per ejaculate. Abnormal semen analysis results may lead us to different types of treatments, either to improve the motile sperm count or to optimize their performance by Intrauterine insemination (IUI) or Intracytoplasmic sperm injection (ICSI).
