Question
To ask the Secretary of State for Health how many women were admitted to hospital with ovarian hyperstimulation syndrome in each of the last five years for which figures are available; how many adverse incidents were recorded in licensed clinics in that period; and what the severity grading of each such incident was.

The Human Fertilisation and Embryology Authority (HFEA) has advised that the data it holds on these issues are as follows:

| 2009-10 | 497 | 7 | 308 | 146 | 36 |
| 2010-11 | 586 | 1 | 292 | 255 | 38 |
| 2011-12 | 571 | 3 | 206 | 308 | 54 |
| 2012-13 | 503 | 0 | 183 | 261 | 59 |
| 2013-14 | 506 | 4 | 203 | 255 | 44 |
Of these, the number of cases of Ovarian Hyperstimulation Syndrome (OHSS) reported to the authority is as follows:
| Number
of
OHSS | Moderate | Severe | |
| 2009-10 | 121 | 1 | 120 |
| 2010-11 | 221 | 122 | 99 |
| 2011-12 | 241 | 196 | 45 |
| 2012-13 | 179 | 134 | 45 |
| 2013-14 | 192 | 142 | 50 |
The HFEA has also advised that licensed fertility clinics are only required to report instances of OHSS to the authority that require a hospital admission with a severe grading, although in practice clinics often report moderate OHSS as well.
