Enough is enough! Patients who do not conceive on 600 IU/d of gonadotropins show no improvement from an additional 150 IU of LH activity

Studies have suggested that supplemental LH improves outcomes in assisted reproductive technology (ART) cycles. In this retrospective review, an additional 150 IU of LH activity did not improve ART outcomes in women undergoing a second round of IVF/ intracytoplasmic sperm injection (ICSI) after an initial failed cycle using 600 IU of gonadotropins.
