HC Deb 12 March 1996 vol 273 c591W
Mr. Alton

To ask the Secretary of State for Health what assessment he has made of the probability of an ectopic pregnancy being created in a treatment cycle using(a) frozen embryos and (b) fresh embryos. [19789]

Mr. Horam

[holding answer 8 March 1996]: As recorded in the records of the Human Fertilisation and Embryology Authority, the latest available data are from 1993. This suggests that the risk of an ectopic pregnancy following fresh embryo transfer is seven per 1,000 patients; the risk following frozen embryo transfers five per 1,000 patients.
