Intrauterine insemination (IUI) is a fertility treatment that involves placing washed and concentrated sperm directly into the uterus using a catheter. When donor sperm is used for IUI, it can be a viable option for individuals and couples who have male factor infertility, genetic disorders that can be passed onto offspring, or single individuals or same-sex couples who desire to have a child.
The success rates of IUI with donor sperm can vary depending on several factors, such as the age of the female partner, the number of IUI cycles attempted, the quality and quantity of the sperm used, and the cause of infertility. However, studies have shown that the success rates of IUI with donor sperm range from 10-20% per cycle.
Age of the Female Partner
The age of the female partner can have a significant impact on the success rates of IUI with donor sperm. Women under the age of 35 have a higher chance of getting pregnant with IUI, and the success rates decrease as the female partner’s age increases. According to the American Society for Reproductive Medicine (ASRM), the success rates of IUI with donor sperm for women under the age of 35 range from 15-20% per cycle, while the success rates for women between the ages of 35 and 40 drop to 10-15% per cycle.
Number of IUI Cycles Attempted
The success rates of IUI with donor sperm can also depend on the number of cycles attempted. The chances of getting pregnant with IUI increase with each cycle attempted, but after three to six cycles, the success rates tend to plateau. The ASRM recommends that couples try IUI with donor sperm for up to six cycles before considering other fertility treatments.
Quality and Quantity of the Sperm Used
The quality and quantity of the sperm used for IUI can also affect the success rates. Donor sperm that has high motility and a high sperm count is more likely to result in pregnancy than sperm with low motility and a low sperm count. The sperm used for IUI is typically washed and concentrated to remove any impurities and increase the chances of fertilisation.
Cause of Infertility
The cause of infertility can also play a role in the success rates of IUI with donor sperm. If the female partner has a known fertility issue, such as ovulation problems or endometriosis, the success rates of IUI may be lower. On the other hand, if the cause of infertility is solely due to male factor infertility, IUI with donor sperm may be a more effective option.
In addition to these factors, it is important to note that success rates can also be affected by the fertility clinic performing the procedure. Clinics with experienced and highly trained staff tend to have higher success rates than those with less experience. Therefore, it is important to research and choose a reputable fertility clinic when considering IUI with donor sperm.
Overall, IUI with donor sperm can be a successful fertility treatment option for individuals and couples struggling with infertility. The success rates may vary depending on several factors, but with proper medical guidance and support, many couples can achieve their dream of having a child.
