Question to the Department of Health and Social Care:

To ask the Secretary of State for Health, how many incidents involving ovarian hyper stimulation syndrome were recorded in licensed HFEA clinics in each year since 2011; and what the severity grading was of each such incident.

The Human Fertilisation and Embryology Authority has advised that it only requires clinics to report cases of severe or critical ovarian hyper stimulation syndrome. There were no Grade A (critical) incidents reported in this time period.
