13 You said in your heart,
“I will ascend to the heavens;
I will raise my throne
above the stars of God;
I will sit enthroned on the mount of assembly,
on the utmost heights of Mount Zaphon.b
14 I will ascend above the tops of the clouds;
I will make myself like the Most High.”
Isaiah14:13-14
Scientific advances will soon allow children to have any number of parents, legal experts warn.
The arrival of ‘multiplex parenting’ is a ‘mere matter of time’ as the techniques have been shown to work on mice, according to a study.
In theory, any number of parents from three upwards – of either sex – could contribute DNA to create a baby.
Sonia Suter, a law professor at George Washington University, has explored the issues raised by the technique, called in vitro gametogenesis (IVG).
She suggests babies could be used to create ‘clans’ of large numbers of people, linked through their shared offspring.
The method would also enable the creation of ‘solo’ children from one parent – as well as hope for infertile adults who would not need a donor egg or sperm.
Professor Suter said that while technical challenges remain, IVG ‘potentially allows for methods of procreation that have never been possible before’.
‘IVG could facilitate multiplex parenting, where groups of more than two individuals – whether all male, all female, or a combination – procreate together, producing children who are the genetic progeny of them all,’ she said.
Writing in the Journal of Law and the Biosciences, the professor added: ‘Procreation in this manner troubles many people because of its significant divergence from our understanding of reproduction as something that occurs between two people.’
She said multiplex parents could theoretically lead to a ‘positive outcome’ for a child as ‘the more adults who feel responsible for the child’s wellbeing, the better off the child is likely to be’. But she said confusion and conflict might arise about the roles of the many parents.
The more biological parents there are, the smaller each one’s genetic link to the child. A youngster with two parents, for instance, gets 50 per cent of its genetic material from each. So a child created by four people using IVG would get 25 per cent of its DNA from each person – equivalent to the genetic share of a conventional baby’s grandparents.
In theory, any number of parents from three upwards – of either sex – could contribute DNA to create a baby.
Professor Suter said: ‘For example, if 32 individuals engaged in multiplex parenting, in genetic and generational terms they would be like great-great-great-grandparents to the child.’ This is because a child conceived conventionally has 32 great-great-great-grandparents.
She added: ‘Thirty-two adults simply cannot all have the kind of intimate relationship that is central to social parenting … as the number of intended parents increases, the social connections inevitably thin and intimacy diminishes, making multiplex reproduction more like the creation of clans.’
The science behind IVG relies on cells that can be made to develop into sperm or egg cells, known collectively as gametes. It means a woman could produce a sperm cell, or a man could produce an egg cell.
