A "kiss" before conception: triggering ovulation with kisspeptin-54 may improve IVF.

A 30-year-old primigravid (G1P000) female with infertility secondary to her partner's oligospermia and her chronic anovulation presented 13 days after an oocyte retrieval for in vitro fertilization (IVF) with a positive home pregnancy test, abdominal distention, a 5-pound weight gain, nausea, shortness of breath, and reduced urinary frequency. Her IVF cycle included the usual cocktail for gonadotropin stimulation and was uncomplicated, except for excessively stimulated ovaries that led to a peak estradiol level of 6,000 pg/ml and the retrieval of 30 oocytes. Her past history was relevant only for anovulation due to polycystic ovarian syndrome (PCOS), though her preprocedure body mass index was normal at 21 kg/m2. Pelvic ultrasound revealed abundant ascites and enlarged ovaries, at 8 cm average diameter. Serum human chorionic gonadotropin (hCG) concentration was 200 mIU/ml; she was hemoconcentrated (hemoglobin 16 g/dl), with normal liver function and coagulation testing. An ultrasound guided, transvaginal paracentesis removed 4 liters of straw-colored fluid, resulting in significant short-term symptom relief.
