To ask the Secretary of State for Health, pursuant to the Answer of 24 June 2014, Official Report, columns 156-7W, on ovarian hyperstimulation syndrome (OHSS), if he will make it his policy that all cases of OHSS are recorded in official statistics and not only those that require hospital admission or are graded as severe.

The Human Fertilisation and Embryology Authority has advised that there is not currently an evidence base to predict the cohort of patients that may develop ovarian hyperstimulation syndrome (OHSS). This means that there would be little clinical value in requiring licensed fertility clinics to report every incidence of OHSS.
