Luteal phase stimulation versus follicular phase stimulation in poor ovarian responders: results of a randomized controlled trial.

abstract：BACKGROUND:Endometriosis has been shown to be associated with second- to third-trimester pregnancy complications such as preterm birth and placenta previa, but the evidence is inconsistent. We hypothesized that endometriosis severity might affect these inconsistent results. Therefore we aimed to conduct a retrospective...
