Human Fertilisation and Embryology Bill [HL]

May I ask my noble friend Lord Winston a question on this research, which he has often referred to? As he rightly pointed out, there is not that much research; there is only one longitudinal study in this country. Would he agree that the sample for that research was quite small? At the age of roughly only 16 or 17, the young people going through this are still quite young, so we cannot really say yet what the results of the experience of having same-sex parents are. One thing that we can say is that, of the sample of 25 children growing up in lesbian families, six have had a same-sex relationship while growing up, whereas in the heterosexual sample none has had such a relationship. That may not mean very much, but it suggests that the research that he refers to is slightly more controversial than one might think on first looking at it.
