Intracytoplasmic sperm injection (ICSI) is a fertility treatment that involves injecting a single sperm directly into an egg in order to fertilize it. The success rate of ICSI depends on various factors.
Success Rates of ICSI
The most important factors are the age of the female partner, the cause of infertility, and the quality of the sperm used. In general, the success rate of ICSI is similar to that of in vitro fertilization (IVF). In the United States, the national average live birth rate per ICSI cycle is around 50%. However, success rates can vary widely depending on the specific clinic and the individual patient’s circumstances.
Factors Affecting Success Rates
- Age: Women under the age of 35 have the highest success rates with ICSI, with around a 60% chance of having a live birth. The success rate decreases as the woman gets older, with women over the age of 40 having a success rate of around 20%.
- Cause of Infertility: In cases where the cause of infertility is unknown, the success rate is around 50%. For couples with known causes of infertility, such as problems with the man’s sperm or the woman’s eggs, the success rate may be lower.
- Sperm Quality: The quality of the sperm used for ICSI can also affect the success rate. Sperm with good motility and morphology (shape) are more likely to result in a successful pregnancy than sperm with poor motility or morphology.
It is important to discuss the success rates of ICSI with a fertility specialist to get a more accurate idea of what to expect. While the success rate of ICSI may not be as high as some other fertility treatments, it can be a good option for couples with male infertility who are trying to have a baby.
