What's next for IVF? Automation, artificial intelligence (AI) and advanced screening technologies are transforming reproductive medicine. Forty-eight years since Louise Brown's groundbreaking birth, scientists continue to refine the process, aiming for higher success rates and greater accessibility.

The Carlos Simon Foundation in Valencia is developing devices like a uterus-on-a-chip, which could one day standardize embryo implantation. But the journey from lab dish to uterus remains as mysterious as ever: only 40% to 60% of healthy-looking embryos actually 'stick' inside the uterine lining.

Meanwhile, genetic tests like PGT-A are helping embryologists select the 'best' eggs and sperm by checking for aneuploidy. This test is particularly beneficial for older women, cutting down on miscarriages and increasing pregnancy rates. But as we rely more on AI to choose our futures, do we risk missing out on nature's mysteries?

While these advancements may streamline the process, they also raise complex ethical questions about genetic manipulation. The race to perfect IVF continues, but the human body remains a complex enigma.
