"However, this could soon be about to change. In a stunning breakthrough this week, scientists revealed they've been able to create human eggs from skin cells. The technique opens the possibility for DNA from a man's skin cells being placed inside a donor egg, before being fertilised by another man. In theory, this could allow two men to have a baby, without any DNA from a woman."
"Sperm cell insertion During heterosexual reproduction, genetic material carried by the sperm combines with genetic material from a female contained in the egg. A biological baby to be born to a same-sex couple would of course have to have genetic material from both parents - from two sets of sperm, for example. While this may sound like an impossibility, scientists in China have excitingly demonstrated that it is feasibly possible."
"The experts managed to insert two sperm cells - one from each father - into a mouse egg whose nucleus had been removed. A gene editing technique was then used to reprogram parts of the sperm DNA to allow an embryo to develop - a process called androgenesis. The embryo (featuring the genetic material from two fathers) was transferred to a female womb and allowed to grow to term."
Scientists have created human eggs from skin cells, enabling a man's DNA to be placed in a donor egg and potentially fertilised by another man. Researchers have explored lab-grown sperm, eggs and parthenogenesis as routes for same-sex biological parenthood. Chinese scientists inserted two sperm into an enucleated mouse egg and used gene editing to reprogram sperm DNA, a process called androgenesis, producing offspring that reached adulthood and reproduced. The techniques could, in principle, allow two men to share genetic parenthood without female DNA. Several reproductive technologies remain experimental and involve ethical and technical challenges prior to human application.
