Sperm Motility And IUI

Low sperm motility, while it is not the most common of the possible causes of male factor infertility, can be one of the most frustrating causes of male factor infertility. Sperm motility refers to a measurement of how the man’s sperm are moving. It measures, as a percentage of the total sperm, how many sperm are moving forward at such a pace that they will reach the fallopian tubes in order to fertilize an egg. There are relatively few treatments for low sperm motility, medically speaking. And, while other treatments, such as nutritional supplements may be helpful for some men, the fact of the matter is that many men with low sperm motility have to rely on some form of reproductive assistance.

IUI, or Intrauterine Insemination, is the most basic of the reproductive treatments available. In this procedure, sperm are “washed” and then placed into the uterus directly. This procedure helps a higher number of sperm to make it to the fallopian tubes, where it can fertilize an egg. IUI is an effective method of reproductive assistance in some cases. IUI is especially effective, in terms of male factor infertility, when a man has a low sperm count, because it allows the health care provider or reproductive fertility specialist to concentrate sperm and place them in a much more beneficial spot. However, low sperm motility and IUI are not a particularly good match.

When you have a problem with sperm motility more aggressive treatments are often necessary. IVF, or In Vitro Fertilization, is often a better option for a man with low sperm motility than IUI. With IVF, sperm motility becomes less of an issue. Another method of addressing low sperm motility is with a procedure known as ICSI, which stands for intracytoplasmic sperm injection. In this procedure, the sperm are inserted directly into the center of the egg for fertilization. ICSI, rather than IUI, is the preferred treatment when a couple is having fertility issues due to a problem with low sperm motility.
