Question to the Department of Health and Social Care:

To ask the Secretary of State for Health, how many (a) non-patient egg donors and (b) egg-share donors were admitted to hospital for ovarian hyperstimulation syndrome in each year since 2009.

The Human Fertilisation and Embryology Authority (HFEA) has advised that licensed fertility clinics are only required to report instances of ovarian hyperstimulation syndrome (OHSS) to the authority that require a hospital admission with a severe grading, although in practice clinics often report moderate OHSS as well. The HFEA does not, therefore, hold definitive data on the number of women admitted to hospital with OHSS, including non-patient egg donors and egg-share donors.

Information on the number of cases of OHSS reported to the HFEA, that were assessed as moderate or severe, was given in my Written Answer to the hon. Member for Heywood and Middleton (Jim Dobbin), on 24 June 2014 Official Report, columns 156-7W.
