The ICSI success rate is reported according to the woman's age, as a woman gets older the IVF success rates go down. IVF success rate usually goes down after crossing 40 (age).
As it allows the selection of the best sperm by the embryologist and direct injection into the egg. Intracytoplasmic sperm injection sometimes used as a further part of IVF or IUI in the cases where there are male infertility issues, such as the number and/or motility of the sperm itself. |
Live Births per Egg Retrieval:
- For women younger than 35, the percentage of live births per egg retrieval is 54.4 percent.
- For women ages 35 to 37, the percentage of live births per egg retrieval is 42 percent.
- For women ages 38 to 40, the percentage of live births per egg retrieval is 26.6 percent.
- For women ages 41 to 42, the percentage of live births per egg retrieval is 13.3 percent.
- For women ages 43 and up, the percentage of live births per egg retrieval is 3.9 percent.
- Various Genetically factors
- Fertility history
- Age of the female partner
- Lifestyle factors including weight and smoking
- Conditions contributing to infertility
- Quality of eggs and number of eggs recovered
- Quality of sperm
One Cycle Statistics vs. Multiple Cycle Statistics:
Something else that's important to realize is the statistics above are for one egg retrieval. ICSI success increase if you can do more than one IVF cycle, and it's typically recommended that you plan on it.
Studies shows that women who conceived with IVF treatment went through an average of 2.7 cycles. They found that the chances for success for women of all ages after three IVF cycles were between 30 – 42%. The actual fact is to improve success you should try for at least three IVF cycles.
What about trying for more than three cycles:
The specific study found that pregnancy success continued to improve (slightly) for up to five cycles. After that, the odds plateaued.

As IVF cost is high, it is expensive, also the psychological distress experienced by couples, makes multiple IVF cycles difficult. Few patients are willing to go through more than two or three cycles. |
Comparing Statistics:
It is important to understand the data presented when comparing ‘success rates’ between clinics. Often pregnancy rates can be quoted and these will always be higher than live birth rates. A clinic’s success rate may also be influenced by its policies for cancelling cycles and by the number of embryos transferred.

Because live births can be calculated as a percentage of cycles started, egg collections or embryo transfers, it is very important to compare like with like when reviewing results. For example, the percentage of live births per egg collection is lower than the percentage of live births per embryo transfer. There are less egg collections than cycles started because some cycles are cancelled before egg collection.
Results indicate that ICSI in an effective option in couples with different causes of subfertility. These variables were integrated into a statistical model to allow the prediction for the chance of pregnancy following ICSI cycles. It is involve that each infertility center gather enough information about the causes of infertility in order to provide more information and better assistance to patients. Therefore, we suggest that physicians prepare adequate training and required information regarding these procedures for infertile couples in order to improve their knowledge.
