It is three years since the Human Fertilisation and Embryology Authority reviewed its guidelines for sperm, egg and embryo donation in the appropriately acronymed SEED report. But reproductive medicine has moved on so swiftly that Professor Lisa Jardine, who took over last April as the authority’s chairman, believes that it is time to return to the issue. In an interview with The Times she called for a fresh debate on two of the most controversial aspects of donation. First on her agenda is the question of when family members should be allowed to donate to one another. She is concerned about intergenerational donation, such as in two cases in 2007. In one, a Briton aged 72 provided sperm to his daughter-in-law, while in the other a Canadian, Melanie Boivin, froze eggs for her daughter, Flavie, 7, who has Turner syndrome and will become infertile.
