Intrauterine insemination (IUI) is a fertility treatment in which sperms are placed into a woman’s uterus directly. In this process the sperms travel through the path into the uterus naturally. The success rates in this process are based on the reasons needed for a fertility treatment.
Age: Age plays a very important role in success of IUI treatments. If the age of a woman is above 40 success rates are as low as 3 to 7 percent. In this case it is advised that a woman should consider IVF treatment instead of IUI.
IUI has a better success rate when infertility of a couple (male or female) is mild to moderate. It is not very successful if infertility in a couple is severe. If there is no female infertility and donor sperms are to be used, an IUI treatment is successful. Studies have shown that IUI treatment is also successful if the cause of infertility is cervical mucus. A doctor can help to determine the best treatment to help achieve pregnancy.
