The chances of multiple births with IUI are similar to those of a natural pregnancy, with the chances of multiple births rising if ovulation induction treatment is done. If the woman preparing for pregnancy has normal ovulation, she may choose not to use ovulation induction treatments and go directly to IUI in her natural cycle. Sperm is artificially injected into the woman’s uterus, and the process is similar to the chances of multiple pregnancies with natural insemination. If more than two follicles grow, then twin pregnancies are possible at maturity. Three makes it possible to produce a triplet pregnancy. Some women ovulate normally but may not become pregnant after one or two natural cycles or cycles without IUI to induce ovulation. In order to improve the pregnancy rate and increase the chances of pregnancy, ovulation induction therapy will be administered, then the chances of a multiple pregnancy are increased. If artificial insemination is required, you need to consult a medical professional for the next step in your pregnancy preparation plan.
