At Arizona Associate for Reproductive Health, we provide both intrauterine insemination (IUI) and in vitro fertilization (IVF). Our fertility specialists will discuss IUI versus IVF with you to determine which type of fertilization technique is best for you. In many cases, patients will undergo both types of treatments during their fertility journeys.
Artificial insemination or intrauterine insemination, where partner sperms are prepared in a laboratory and then inserted through a small catheter into the uterus, this is called artificial insemination or IUI. In in vitro fertilization, in vitro is outside body fertilization, where eggs are obtained surgically from the ovaries and they are fertilized in a Petri dish with a partner's sperm. This is called in vitro fertilization.
Success rates of IUI, as well as in vitro fertilization, depend on many factors. The most common factor is age. Increasing age is related to the decreasing success of artificial insemination, as well as in vitro fertilization.
Typically speaking, in vitro fertilization is more successful, probably three times more successful than intrauterine insemination, regardless of age. Depending upon age, usually we mention considering doing three to five controlled hyperstimulation using Clomid or Femara, with artificial insemination before moving on to in vitro fertilization. In vitro fertilization is technologically a more advanced treatment than intrauterine insemination. In in vitro fertilization we are more in control over obtaining eggs and fertilizing them in a Petri dish, as well as monitoring the growth of the embryos and selecting the best embryo and transporting that embryo into the uterus. This is what is not done with artificial or intrauterine insemination.
