Hyperreactio luteinalis following frozen embryo transfer managed by fetal reduction.

We report a rare case of hyperreactio luteinalis (HL) which developed in association with triplet pregnancy in a 27-year-old woman who underwent assisted reproductive technology treatment for primary infertility. She had undergone frozen embryo transfer 2 months after ovarian retrieval. She presented in the first trimester with abdominal pain and distension associated with ovarian enlargement and did not respond to conservative management. Fetal reduction was done from triplets to twins which resulted in good symptomatic relief for the patient. Fetal reduction may be an effective approach in such situations when conservative strategies fail in HL.
