Intracytoplasmic Sperm Injection Success Rate

The sperm injection success rate in the ICSI method plays an important role in making couples' dreams of having a baby come true with IVF treatment. Thanks to superior technology, the fertilization process is accelerated and the chances of success are increased by injecting men's sperm cells directly into the egg cell. But what is the success rate of this miraculous treatment method?

First of all, it is important to say that the ICSI successrate varies depending on the age of the couple, the woman's ovarian reserve, and the quality of the man's sperm. In particular, if the woman is over 35 years old, the success rate tends to decrease. However, in general, the ICSI success rate ranges between 50 percent and 80 percent. This means that three out of four couples can have a baby with this method.

How Many Times Can ICSI Be Performed?

The ICSI method is an advanced assisted reproductive technique developed for couples with male-induced infertility problems and used in conjunction with IVF treatment, increasing the sperm injection success rate. ICSI is based on the principle of fertilization by directly combining sperm and egg in a laboratory environment. There is no strict limit to the number of times ICSI can be repeated. However, factors such as age, general health, stress level, and financial burden of the couple should be taken into consideration when deciding how many attempts a couple should make.

Pregnancy Rates After ICSI

Pregnancy rates after ICSI can vary depending on several factors. These factors include age, sperm and egg quality, duration and causes of infertility, medications, and treatment protocols. In general, pregnancy rates after ICSI vary between 70-80 percent. However, since each couple's situation is different, it is difficult to state an exact success rate for pregnancy after Intracytoplasmic sperm Injection. In particular, the age of the woman has a significant impact on the ICSI success rate in pregnancy.


For women under 35 years of age, pregnancy rates with ICSI are higher and decrease with age. For example, for a woman under the age of 35, the pregnancy rate may be 65 percent whereas, for a woman aged 40 and over, the rate may drop to 35 percent. Another factor affecting the ICSI success rate is the source of the sperm used. Sperm from the testicles has the potential to provide higher pregnancy rates, whereas sperm from the epididymis or other sites may result in lower rates.

What to Do If the Sperm Injection Procedure Fails?

Sperm injection is one of the assisted reproductive techniques available for couples with infertility problems. However, successful sperm injection is not always guaranteed and in some cases, the procedure may fail. In such cases, there are some strategies and methods that couples can apply.

·        Examining the Causes

First, the reasons for the failure should be examined in detail. This will be done by the treating specialist and will take into account the couple's health status, age, environmental factors, and previous experiences.

·        Exploring Alternative Treatment Methods

In the absence of a successful sperm injection, the couple may consider other assisted reproductive techniques. Methods such as in vitro fertilization (IVF), intracytoplasmic morphology selected sperm injection (IMSI) and gamete intrafallopian tubal transfer (GIFT) can be considered as alternatives to the failed sperm injection procedure.

·        Improving Sperm and Egg Quality

When sperm injection fails, the couple may be advised to make lifestyle changes to improve sperm and egg quality. These changes may include regular exercise, a balanced and healthy diet, reducing stress, and limiting alcohol and cigarette consumption.

·        Seeking Psychological Support

Failure in this process can cause psychological difficulties for couples. Therefore, couples need to seek professional psychological support to get through this process more healthily.

·        Waiting for the Right Time

After a failed sperm injection procedure, the couple should wait for a suitable period for their bodies and minds to recover. During this time, the couple needs to follow the health checks and arrangements recommended by their doctor.

Remember that not every unsuccessful experience will affect the outcome of the treatment and couples should not despair. It is important to be patient in this process to increase the ICSI success rate.
