The risks associated with IVF are minimal. One of the rare complications of hormonal treatment is hyperstimulation (OOHS), resulting in an enlargement of the ovaries. The main symptom of hyperstimulation is pain in the lower abdomen, with the occasional accumulation of fluid in the abdominal cavity. Today's medicine can alleviate symptoms, and hyperstimulation then subsides spontaneously. Pregnancy following IVF is no different from natural pregnancy and presents the same risks (premature labour, miscarriage, etc.).
