Selective use of corifollitropin for controlled ovarian stimulation for IVF in patients with low anti-Müllerian hormone

AbstractCorifollitropin, a long-acting follicle-stimulating hormone (FSH) analogue used for in vitro fertilization (IVF), does not allow individualization of dosage, and the ovarian response is similar to around 300 IU of daily recombinant FSH. This has raised concerns about the risk of ovarian hyperstimulation syndrome (OHSS) when used in standard patients. We administered corifollitropin selectively to patients with anticipated low to moderate ovarian response based on antimullerian hormone levels in the lower quartile. The end points were oocyte distribution and occurrence of OHSS in women with AMH  ≤15 pmol/L. The study included a cohort of 368 patients treated in 599 cycles. Post hoc the cohort was subdivided according to AMH. With increasing baseline AMH, the number of oocytes increased from a mean of 2.7 (range 0–8 with AMH  <3 pmol/L) to 6.3 (range 0–15 with AMH 10–15 pmol/L) oocytes. Cancellations of retrievals and transfers decreased significantly with increasing AMH. Overall, the ongoing live p...
