Ovarian Hyperstimulation Syndrome (OHSS)

This is a potential complication of hormonal stimulation of the ovaries, in which the ovaries most often overreact to the administered drugs. Hyperstimulation syndrome is accompanied by pressure and pain in the lower abdomen, an enlarged abdomen, impaired urination or nausea and vomiting. These symptoms usually subside within two weeks but serious cases can also result in long-term hospitalisation of the patient. However, today's modern ovarian stimulation procedures allow doctors to minimise the occurrence of severe forms of hyperstimulation syndrome.
