Human Fertilisation and Embryology Bill [Lords]

I agree with what the right hon. Gentleman is saying. Another example of the sort of research to which he has referred is the process by which ovarian tissue, for example, is engrafted onto an animal and then tested for the effects of chemotherapy. That is impossible—or at least very difficult—to do in vitro, without that sort of animal model. For good reasons, the Bill defines gametes as cells in the ovary or the testes at any stage in their development, including their very early stages. That is why banning the placement of human gametes in animals would prevent research, currently being done in this country, that involves research into the effect of chemotherapy on those cells' development. Clearly, that research would play into the issue of infertility.
