Previous studies suggested ovarian stimulation was associated with lower birth weight and higher risk of preterm delivery (PTD) from fresh embryo transfers (ETs). However, whether the increased risk differs between distinct ovarian stimulat…

PURPOSE: To establish an index to predict ART outcomes and to identify infertile patients who need LH supplementation during ovarian stimulation. METHODS: Serum LH concentrations were measured during the mid- and late-follicular phase in 8…
