OBJECTIVE: To investigate the symptoms and outcomes of ovarian stimulation in patients with a history of hyperemesis gravidarum.

DESIGN: Retrospective case series.

SETTING: Research laboratory of a university hospital.

PATIENT(S): Participants in an ongoing study on hyperemesis gravidarum that reported ovarian stimulation for gestational surrogacy.

INTERVENTION(S): Review of medical records.

MAIN OUTCOME MEASURE(S): Pregnancy history, symptoms, estradiol level and mature oocyte number in cases, and nausea and vomiting level reported in surrogate.

RESULT(S): Three cases in their early thirties with a history of hyperemesis gravidarum presented with severe nausea and vomiting during ovarian stimulation and ovarian hyperstimulation syndrome. Gestational carriers reported normal nausea and vomiting of pregnancy.

CONCLUSION(S): This series provides lessons for in vitro fertilization for cases with a history of hyperemesis gravidarum and their gestational carriers as well as insight into the cause of hyperemesis gravidarum and its potential role in fertility. A link between hyperemesis gravidarum and an evolutionary advantage of increased fertility suggests a novel theory to explain the selection for nausea and vomiting in pregnancy.
