Gene Editing Raises Concerns as Doctors Delve into Pre-Implanted Embryos

In a world where life hangs in the balance, doctors are now exploring the vast possibilities of gene editing on pre-implanted embryos. While regulations and debate continue to unfold over this emerging technology, an increasingly contentious issue comes into focus: sex selection during IVF.

Some fertility clinics have started incorporating embryo screening as part of their IVF treatment plans, a technique known as Preimplantation Genetic Diagnostics (PGD). Not only does it screen for genetic conditions that could lead to congenital disorders or birth defects but also enable parents to select the sex of their desired offspring when performing in vitro fertilization.

However, amidst these advancements, some argue about the moral and scientific implications of gene editing. As researchers continue to push the boundaries of this technology, concerns over its potential long-term effects on future generations grow louder. Critics point out that there is no concrete evidence yet that demonstrates its safety or effectiveness in human embryos.

A striking instance of this concern was seen in 2018 when a Chinese scientist successfully created the world's first genetically edited twin babies using CRISPR-Cas9 technology. By editing the genes responsible for HIV, the scientist effectively protected the twins from contracting the disease.

The babies, born in 2017, have sparked both global curiosity and intense scrutiny over their parents' actions. While experts closely monitor their health to assess long-term effects of gene editing on human embryos, the incident has highlighted a critical need for clear regulations regarding this highly contentious issue – one that not all countries are equipped to address yet.

Meanwhile, as governments worldwide grapple with how to regulate this new frontier in genetic engineering, scientists will have to remain vigilant and scrutinize their methods to ensure that they prioritize ethics and patient safety. Only time can bring clarity on the implications of gene editing for pre-implanted embryos – but it's an issue that won't be ignored for long.
