Last year in the United Kingdom, an increasing number of women suffered serious complications following In-Vitro Fertilisation according to the HFEA. Doctors are concerned by the increase in cases of severe ovarian hyperstimulation syndrome, which can be potentially fatal.
In 2015, 60 women were admitted to hospital with this type of syndrome – an increase of 40% compared to the previous year . Symptoms include abdominal swelling and pain, nausea, dehydration and the formation of blood clots.
IVF cycles, which is also increasing (68,000 in 2014, 72,000 in 2015), could even partly explain the increase in the number of “unfavourable incidents”.
