If you’re exploring fertility options, you’ve likely come across in vitro fertilization (IVF). However, you might not be as familiar with intracytoplasmic sperm injection (ICSI), a technique used to enhance egg fertilization. Let’s break down the key differences between IVF and ICSI and discuss when each method might be the best choice for you.
What is IVF?
IVF is one of the most widely used and successful treatments for infertility. The process involves retrieving eggs from a woman’s ovaries and fertilizing them with sperm in a lab setting. Once embryos develop, they’re transferred back into the uterus with the hope of implanting successfully.
How Does IVF Work?
In a standard IVF procedure, hormonal treatments stimulate the growth of several eggs. These mature eggs are then collected from the ovaries. The collected eggs are combined with sperm in the lab, allowing the strongest sperm to fertilize the eggs. The fertilized eggs grow into embryos and are cultured for 5-6 days until they reach the blastocyst stage. The healthiest embryo is selected for transfer, and any viable remaining embryos can be frozen for future use. If you’re facing issues like low egg quality or absence of eggs, using donor eggs is also an option.
Who is IVF Suitable For?
IVF might be a good fit if you:
- Have a diagnosed fertility issue, like blocked fallopian tubes or conditions like PCOS or endometriosis.
- Are dealing with unexplained infertility.
- Are older, and your egg count has declined, making natural conception difficult.
- Have tried other treatments, like IUI, without success.
- Are a same-sex female couple or a single woman using donor sperm.
Success Rates
At TFP Fertility, we boast over 35 years of experience in fertility care, helping many families grow. Our average IVF success rate is 38% for both fresh and frozen embryo transfers, but individual outcomes can vary based on age and fertility health.

What is ICSI?
ICSI is a specialized procedure performed during IVF, where a single, healthy sperm is injected directly into an egg. This method can significantly improve fertilization chances since the sperm doesn’t have to penetrate the egg’s outer layer on its own.
When is ICSI Used?
ICSI may be recommended in situations such as:
- Low sperm count in the male partner.
- Poor sperm motility or abnormal sperm shape.
- Sperm retrieval through surgical means.
- High levels of DNA damage in the sperm.
- Previous IVF cycles resulted in few or no fertilized eggs.
- Use of donor eggs or frozen sperm.
Comparing Success Rates with IVF
ICSI is not a standalone procedure but is integrated into traditional IVF cycles. The success rates for achieving pregnancy are similar for both IVF and IVF with ICSI. While fertilization isn’t guaranteed in either case, the fertilization rate with ICSI typically ranges from 50% to 80%.
Cost Comparison
Since ICSI involves a more complex process, it adds to the overall cost of IVF. For instance, at TFP Fertility, a standard IVF cycle is around £5,255, while adding ICSI would increase the cost by about £1,400. Keep in mind that treatment plans are personalized, and costs can vary, so it’s best to discuss your specific situation with your fertility doctor.
Choosing Between IVF and ICSI
ICSI is particularly beneficial for couples facing male factor infertility, such as low sperm count or motility issues. It is also important when a woman has frozen her eggs, as the freezing process makes it harder for sperm to penetrate the egg without assistance.

Summary
In summary, IVF and ICSI are both vital techniques in fertility treatments. IVF is a comprehensive approach that involves fertilizing eggs with sperm, while ICSI is a specialized method used to facilitate fertilization when male fertility issues are present. Each method has its own indications and success rates, and the choice between them should be made with the guidance of a fertility specialist.
