ICSI Success Rates
Intracytoplasmic Sperm Injection (ICSI) is a specialised assisted reproductive technique commonly used in cases of male infertility or previous fertilization failure. Success rates depend on individual medical factors, including age, embryo quality, and overall reproductive health.
At Lifespan Birth, our high success rates are backed by an embryology-led approach focused on laboratory precision, structured protocols, and personalized treatment planning.
What Influences ICSI Success?
- Patient age and ovarian reserve – Age significantly affects egg quality and quantity. A higher ovarian reserve and younger age are generally associated with better response to stimulation and higher success rates.
- Egg and sperm quality – The health of both gametes strongly affects embryo development.
- Underlying infertility causes – Conditions such as endometriosis or genetic issues can play a role.
- Laboratory expertise – Our embryologists and lab facilities exceed international standards.
- Uterine environment – Implantation depends on endometrial receptivity and overall uterine health.
- Embryo quality – The genetic health and developmental stage of the embryo play a critical role in successful implantation and pregnancy outcomes. High-quality embryos have a greater chance of developing normally.
ICSI Success at Lifespan Birth
We are proud that our fertilization and implantation rates are consistently above global benchmarks at 81-93%. While results vary depending on age and medical history, our approach ensures that every patient receives the highest possible chance of success.
Success rates vary by age group. While overall fertilization and pregnancy outcomes may be strong, individual expectations differ based on ovarian reserve, embryo genetics, and uterine factors.
Under 35 Typically higher success probability due to egg quality.
35–39 Good outcomes with careful embryo selection and laboratory precision.
40+ Success influenced strongly by ovarian reserve and embryo chromosomal status.
While age is an important factor in determining ICSI success, Lifespan Birth evaluates each case holistically. Other key factors such as ovarian reserve (AMH levels), embryo quality, sperm quality, uterine condition, and overall health are also carefully considered to provide a personalized treatment approach.
How ICSI Success Rates Are Calculated
Success rates may be reported as fertilisation rate, implantation rate, clinical pregnancy rate, or ongoing pregnancy rate. Our figures refer to clinical pregnancy rates, measured per defined treatment cycle and reviewed on a quarterly basis to ensure accuracy and consistency.
Important Medical Considerations
- ICSI improves fertilization rates but does not guarantee pregnancy.
- Genetic screening improves embryo selection accuracy but is not absolute.
- Implantation depends on embryo quality and uterine readiness.
- Medication response varies between individuals.
- Individual medical assessment is required to estimate realistic expectations.
