Intracytoplasmic Sperm Injection (ICSI) has become an important part of modern fertility treatment. It proves especially useful for couples with male infertility or failed fertilization with standard IVF. ICSI is a complement to conventional IVF and gives embryologists greater control over the process. Jindal IVF Centre in India is a premier fertility clinic that specializes in ICSI for couples looking to enhance the chance of fertilization when natural barriers stand in the way. We help you in ICSI through our cutting-edge lab support and team of highly skilled embryologists. We even adopt a personalized approach and commitment to clinical excellence to better your experience.
This article talks about the success rate ICSI so you can set the right expectations and make informed decisions.
What Is ICSI and How Does It Work?
ICSI is an advanced micromanipulation technique used as a part of an IVF cycle. It is designed to help couples in case sperm quality or function may be limiting factors in achieving pregnancy. This method is ideal for when the sperm count is low, and motility is poor. It is even useful in case of abnormal morphology and failed fertilization with a previous IVF attempt. This is the procedure of ICSI:
- Ovarian Stimulation: The woman receives hormonal medications to stimulate the ovaries and produce multiple mature eggs.
- Egg Retrieval: Eggs are collected through a minor surgical procedure under ultrasound guidance, typically done under sedation.
- Sperm Collection: Sperm is obtained through ejaculation, surgical extraction (such as TESA or PESA), or from a donor, depending on the male partner’s condition.
- Sperm Selection and Injection: Under a high-powered microscope, a single sperm is selected and injected directly into each mature egg using a specialized microneedle.
- Fertilization Monitoring: After injection, the eggs are observed for fertilization over the next 18-24 hours.
- Embryo Culture and Transfer: Successfully fertilized eggs develop into embryos over 3-5 days, after which one or more are transferred into the uterus.
Average Success Rate Of ICSI
Let us have a look at the average success rate of ICSI:
General Global And National Statistics
The success rate ICSI can vary across countries, clinics, and patient profiles. The global clinical pregnancy rates from ICSI range between 35% to 45% per cycle. Higher rates are usually seen in younger women and top-tier fertility clinics.
Jindal IVF is a reputable fertility clinic in India. We maintain competitive success rates that comply with international standards. Depending on patient age, health conditions, and embryo quality, we boast success rates between 35%-40% per cycle.
You must note that several clinics may quote clinical pregnancy rates or pregnancies confirmed by ultrasound. This is not a direct correlation to live births, which can be slightly lower due to miscarriage and pregnancy complications.
Success Rate Per Embryo Transfer Or Per Cycle
The success of the process can be measured per embryo transfer, as to how many embryo transfers lead to pregnancy. It can also be determined by per cycle initiated, including failed fertilization or cycle cancellation due to poor response. A usual rate of 50% per transfer but only 35% per cycle is reported if a portion of cycles do not proceed to the transfer stage.
Younger patients using good-quality embryos often see a higher success rate ICSI per embryo transfer. This is especially true when combined with blastocyst transfers and genetic testing. Rates are slightly lower per cycle as they also account for biological and procedural variables that may prevent embryo formation or transfer.
Comparison With Conventional IVF Success Rates
ICSI usually provides better fertilization rates than conventional IVF in specific scenarios. This is true particularly where male infertility is involved. Poor sperm motility and morphology can prevent sperm from penetrating the egg in standard IVF. ICSI bypasses this issue entirely to offer a higher chance of fertilization.
When sperm is normal, both IVF and ICSI boast comparable pregnancy rates. The main benefit of ICSI is its ability to ensure fertilization in difficult cases, leading to a more reliable clinical pathway. The distinction makes the success rate ICSI an important benchmark for couples facing complex fertility issues.
Factors That Influence ICSI Success Rates
These factors influence ICSI success rates:
Female Age
A woman’s age has a direct impact on the outcome of ICSI. Fertility declines greatly after the age of 30 and drops even more after 35. Women under 35 tend to have the highest ICSI success rates, with 45-55% per cycle. Women from ages 35-37 have slightly reduced rates of 35-45%. By the time they are 40 and above, the outcomes often drop below 25%. After 42, the success becomes challenging and egg donation is required.
Male Factor Infertility
Sperm health still plays an important role in embryo quality and development even when ICSI is designed to bypass male infertility barriers. High sperm DNA fragmentation and infections, along with hormonal imbalances can impair embryo growth. This causes concern even when ICSI successfully fertilizes the egg.
Advanced sperm selection techniques like MACS (Magnetic-Activated Cell Sorting) or IMSI (Intracytoplasmic Morphologically Selected Sperm Injection) are supplementary options. These can considerably improve embryo outcomes in these cases.
Embryo Quality
The quality of embryos developed after the ICSI process has a strong relation with pregnancy and birth outcomes. Embryos are generally graded based on factors like cell symmetry, fragmentation, and development pace. Jindal IVF provides time-lapse embryo monitoring and extended blastocyst, as well as preimplantation genetic testing (PGT). This helps ensure the highest quality embryo selection, along with improved chances of implantation and reduced miscarriage risks.
Uterine Health
The embryo may be the healthiest one, but it cannot be implanted successfully if it is in an unhealthy uterus. Factors like thin endometrium and fibroids, along with endometrial polyps or chronic endometritis can severely hinder implantation. Uterine health can be ensured through hysteroscopy and ultrasound assessment. Medications like estrogen support or PRP therapy are important to support a successful pregnancy.
Lab And Clinic Quality
The outcomes are directly affected due to the environment in which fertilization and embryo culture occur. Jindal IVF boasts state-of-the-art laboratories with controlled air quality, temperature, and humidity. These are the optimal conditions for embryo development. Our patients benefit greatly from our advanced lab technologies, experienced embryologists, and world-class protocols that directly enhance the success rate ICSI.
Number Of Embryos Transferred
The number of embryos transferred may affect the success rate but also pose risks. Transferring multiple embryos at a time can increase the likelihood of pregnancy. However, it also raises the chances of twins or triplets, which come with great obstetric risks. A lot of clinics now prefer elective single embryo transfer (eSET) with young women, where good-quality embryos are used and supported by PGT.
ICSI Success Rates Based On Age Groups
Let us break down how the success rate ICSI usually varies by age group:
|
Age Group |
Success Rate per Cycle |
|
Under 35 |
45% – 55% |
|
35 – 37 |
35% – 45% |
|
38 – 40 |
25% – 35% |
|
41 – 42 |
15% – 25% |
|
Over 42 |
5% – 15% |
Age is not the sole factor behind the success of ICSI. However, it is the most predictive one. Egg donation is usually considered for women over the age of 42 so the outcomes are improved.
Live Birth Vs. Clinical Pregnancy Rates With ICSI
Sometimes, clinical pregnancy rates may be advertised as sole parameters. Patients need to inquire about live birth rates that reflect a more meaningful outcome. A clinical pregnancy is confirmed by the presence of a gestational sac on ultrasound. On the other hand, a life indicates a healthy delivery.
- Clinical Pregnancy Rate: 35%-45%
- Live Birth Rate: 25%-35%
When interpreting the success rates behind ICSI, it is important to understand the two of these, since there can be issues of miscarriage or biochemical loss even in clinical pregnancy.
Tips To Improve ICSI Success Rates
These are the tips to improve ICSI success rates:
Lifestyle Changes
Small changes on the ends of both parents can significantly improve fertility. Here are some changes that go a long way:
- Stop smoking and alcohol use.
- Eat a balanced, whole-foods-based diet.
- Exercise moderately and maintain a healthy weight.
- Reduce stress through meditation, yoga, or counseling.
- Ensure adequate sleep and hydration.
These habits are great for improving egg and sperm quality, as well as hormonal balance and overall reproductive health.
Pre-treatment Fertility Optimization
Underlying issues like PCOS and hypothyroidism need to be addressed before starting ICSI. You should also look for issues like insulin resistance and endometriosis. Men benefit greatly from antioxidant supplements like Vitamin C and E. These improve their sperm motility and morphology to a great degree.
Women benefit the most from supplements like folic acid and DHEA since they can enhance ovarian response and egg quality.
Choosing The Right Clinic
The right fertility clinic is the best choice you can make to improve your success rates with ICSI. Here are some standards the right clinic upholds:
- High ICSI experience.
- Transparent reporting of live birth rates.
- Advanced lab infrastructure.
