On the 25th July, it had been 40 years since the world’s first IVF baby was born. Since then there have been many changes to IVF to make IVF more successful. Here are a few of the significant changes to IVF.

FSH injections

Louise Brown resulted from natural cycle IVF – one egg. FSH injections, also known as follicle stimulating hormone, occur at the start of IVF treatment as they cause follicles containing eggs to develop in the ovaries. This means more eggs are produced and this has improved the efficiency of IVF greatly. Care Fertility still offers natural cycle IVF to some couples though the success rate is much lower than with FSH.

Choosing the best sperm to make the embryos

Injecting the sperm to the egg was reported in 1992 and since then ICSI has been used very commonly to help men with poor sperm quality and couples with reduced fertilisation. Care Fertiltiy is an Australian pioneer of a new technique to improve the efficiency of ICSI, called IMSI.

Incubation and nutrients for embryos

To help an embryo grow, there have been changes to the nutrients in the incubators and types of incubators which has help increase success rates of embryos.

Embryo biopsy

Thanks to scientific expertise, we can now perform biopsies of embryos which has helped to improve success rates by only transferring genetically healthy embryos. Care Fertility offers embryo biopsy to screen for genetic abnormalities.

Freezing of Embryos

We can now extract embryos, store them and later transfer the embryos. This has helped patients who want to preserve their embryos for a later date and improves the overall efficiency of IVF.

There have been many other changes in IVF over 40 years to help with success rates through IVF. What will the changes be over the next 40 years in IVF?
