The Human Fertilisation and Embryology Authority (HFEA) has announced significant advancements in the ability to grow human eggs and sperm in laboratory settings, which could potentially eliminate the need for traditional sexual reproduction.

This process, known as in vitro gametogenesis (IVGs), involves reprogramming stem cells or skin cells to function as eggs or sperm.

Currently, successful IVGs have only been achieved in mice, with a notable achievement being the creation of a healthy offspring from two male mice.

If validated for safety and efficacy, IVGs could revolutionize fertility treatments, offering new options for individuals with low fertility and those in non-traditional family structures.

The concept of multiplex parenting has emerged from these advancements, suggesting that a child could have genetic contributions from multiple parents, which raises complex ethical and social implications.

The HFEA has also expressed concerns regarding 'solo parenting' and its ethical implications, suggesting that certain practices should be banned.

Public opinion on IVGs is generally positive, especially regarding their potential in fertility research; however, there are calls for strict regulation and oversight due to ethical concerns.

As researchers continue to approach this groundbreaking technology, discussions surrounding its regulation and societal acceptance are becoming increasingly urgent.

The potential for lab-grown embryos could lead to genetic selection, reminiscent of themes from the film 'Gattaca', which raises additional ethical questions about genetic engineering and parentage.
