The optimal strategy for stimulation of young women with a low ovarian reserve is still a challenging issue because the physio-pathogeny of this disorder is often unknown. As androgen production by the ovary plays a crucial role in folliculogenesis, it was tempting to speculate that subtle perturbations in ovarian steroidogenesis might participate to the low responsiveness to gonadotrophins. Indeed, analysis of human luteinized granulosa cells has recently provided evidence for some enzymatic deficits in steroidogenesis and altered response to gonadotrophins.

Methods: In this retrospective cohort study, we included 804 patients who were treated between January 1, 2022, and July 1, 2023. Outcomes of ovarian stimulation were compared between the PPOS (n = 206) and GnRH-ant (n = 598).
Objectives: To evaluate the relationship between time since contraceptive implant placement and retrieval outcomes in patients with implant migration into the pulmonary artery.
Study Design: We reviewed all cases of pulmonary artery implant migration referred to the Marie Lannelongue hospital from 2015 through 2020. Using our hospital database, we collected patients' clinical data and removal information to assess the success of therapeutic management according to the delay between implant insertion and removal.
