There are many medical tests that are frequently performed on an apparently infertile couple. First of all, doctors will attempt to determine what the problem is. Often, the first step is to check the sperm count of the male partner. This is probably the least invasive test. Both partners, but especially the female partner, are likely to undergo extensive physical exams. Sometimes the problem is simple, like a low sperm count or low sperm motility. It could also be something as simple as a ph imbalance or other minor issue with the female. If the problem is not found, other more invasive tests may be performed. If a couple decides to undergo fertility treatments, the cause of the infertility needs to be found first. Eventually, many couples decide to undergo hormone therapy or in vetro fertilization. Hormone therapy is relatively noninvasive, although it might not feel that way for the female. In vetro fertilization often involves an egg extraction procedure which is invasive.
