Scientists Work to Improve IVF Success Rates

In vitro fertilisation (IVF) has helped millions of families have children since 1978, when Louise Joy Brown became the first IVF baby. Today, IVF is responsible for about 2% of all births in the United States. However, the procedure still has relatively low success rates. For women aged 35, only 30-39% of embryo transfer cycles result in a live birth.
Many clinics offer expensive "add-ons" like time-lapse imaging, which takes pictures of developing embryos every ten minutes. Clinics claim this increases success rates, but a 2024 study in The Lancet found no significant difference in live birth rates. Despite this evidence, clinics continue charging patients hundreds of dollars for the service.
Researchers are developing genuinely promising techniques. Scientists in the UK have designed a special needle that uses fluid motion to collect eggs more effectively. In Spain, researchers are using magnetic nanoparticles to handle delicate eggs without damaging them. In Australia, scientists are measuring lipid levels in embryos to predict which ones are most likely to develop successfully. While these innovations show potential, they must still be tested in large clinical trials to prove their effectiveness in improving IVF outcomes.
