In 2015, British lawmakers approved a form of germline modification known as “mitochondrial donation” – commonly referred to as “three-parent” in vitro fertilization (IVF).
One-third of irrigated land worldwide is not suitable for growing crops because of the presence of salt – the result of repeated fertilization.
The birth of Louise Brown in 1978, and with her that of human in vitro fertilization (IVF), was a landmark in medical science.
For example, intracytoplasmic sperm injection is a technique in which a single viable sperm is injected into an egg, allowing fertilization to occur even in cases where few healthy sperm are available.
That is only fitting because it was in the UK that a new and problematical moral construct - the embryo in a dish - came into being in 1978, with the birth of the first "test tube" baby, Louise Brown, the product of in vitro fertilization.
Most people approve of in vitro fertilization, but it is the technology that gives the infertile the chance to be parents that also poses moral questions.
Stem cells used in this research are best derived from very early stage embryos created by in vitro fertilization, but this leads to ethical dilemmas.
They concluded that it is ethically permissible to prepare stem cell lines from frozen embryos, but only from those obtained in the course of in vitro fertilization procedures and deemed by donors and their physician to be in excess of clinical requirements.
Indeed, from fertilization on, the environment in which the fertilized egg develops – for example, what the mother eats, whether she smokes or drinks alcohol, and whether she develops diseases or infections – places so-called epigenetic marks on the DNA or on the proteins surrounding it, affecting its function.
