The Causes of IUI Failures

Usually, intrauterine insemination, which is abbreviated as IUI, is the first line of treatment recommended for people with fertility concerns. Suppose a couple has fertility problems such as anovulation, cervical mucus, PCOS, or sperm health problems. In this case, your care specialists recommend IUI to help deposit sperms into your uterus other than what happens during sex, where sperms are deposited in the vagina. Suppose you are interested in trying out IUI Celebration to help you conceive. It would help if you learned the various causes of IUI failures to avoid them to help increase the success rate of this procedure. Discussed below are a few causes of IUI failures.

Poor ovum quality

Generally, as a woman advances in age, the quality of ova or eggs she produces reduces. In most cases, these eggs are also more likely to have some chromosomal abnormalities that might be transmitted to the unborn baby. These abnormalities can also cause poor embryo formation, affecting IUI’s success.


As discussed above, age is one of the essential factors to consider, especially if you are interested in trying IUI. Of importance to note is that age is usually a deciding factor in most treatments, especially if you want to conceive. Generally, fertility usually decreases as you age because the quality of the eggs produced by the ovaries reduces. Therefore, conceiving becomes quite difficult, especially if you are in your menopausal or post-menopausal stage. As a result, the success of certain fertility treatments, including intrauterine insemination, is also reduced.

Poor quality of sperms

Just like it is in women, the quality of sperm also declines as a man gets older. Of importance to understand is that other than the quality of the sperm produced, motility and quantity or amount are also affected. There the male should have their sperm examined to help improve the success rate of IUI.

Menstrual cycle

Before undergoing intrauterine insemination, you are supposed to ensure you are fertile, and ovulation has taken place. Generally, ovulation is a stage during your menstrual cycle when the ovary releases a mature ovum. During this time is when IUI should be performed to promote fertilization and implantation. However, if it is performed twelve or twenty-four hours after ovulation, no fertilization will occur because the ovum will disintegrate while in the fallopian tube. Therefore, the time of fertilization plays an essential role in determining the success of IUI.

Uterine lining

If your endometrial lining is poorly thickened, the fertilized egg or embryo will not be implanted in the uterus for continued growth and development to full term. Therefore, your care providers are supposed to ensure your uterine is well thickened before IUI.

If your IUI fails after two or more trials, your care provider should try another alternative to help you conceive. It is also good to start evaluating other causes of infertility because it might be due to another undiagnosed cause. Therefore, if you are interested in undergoing intrauterine insemination to help you conceive, you can book your appointment at the Center for Reproductive Medicine today.
