Effect of corpus luteum position on hyperemesis gravidarum. A case report.

It has been postulated that the position of the corpus luteum affects nausea and vomiting of pregnancy. Supposedly a corpus luteum arising from the right ovary results in a high concentration of sex steroids in the hepatic portal system, causing nausea and vomiting. A woman with severe hyperemesis underwent excision of a right-sided corpus luteum at 12 weeks. Removal of the corpus luteum failed to modify the course of the disease.
