NCT07466199
The goal of this clinical trial is to learn whether the sudden administration of vaginal micronized progesterone during the late follicular phase can trigger an LH surge and reactivation of oocyte meiosis in healthy oocyte donors aged 18 to 33 undergoing a mild ovarian stimulation cycle. The main question it aims to answer is: * Does progesterone administered in the late follicular phase induce an LH surge and subsequent oocyte meiosis reactivation? Participants will: * Undergo a mild ovarian stimulation with 75 IU of follitropn alfa * Start vaginal micronized progesterone (400 mg every 12 hours) once at least one follicle reaches 15 mm * Have blood samples collected to measure hormone levels before and after progesterone administration * Undergo oocyte retrieval 35-36 hours after the progesterone trigger This is a low-intervention, single-center pilot study including approximately 10 oocyte donors.
NCT06281665
The objective of this research project is to conduct a single-site pilot trial to assess the feasibility and effect of low-dose aspirin to augment vascular recovery in the immediate postpartum period after preeclampsia through two specific aims: 1) to pilot test the feasibility of conducting a randomized controlled trial of postpartum low dose aspirin vs. placebo, and 2) to assess the effect of postpartum aspirin on endothelial function and blood pressure. Our central hypothesis is that postpartum administration of low-dose aspirin following preeclampsia will be feasible, improve endothelial function, and lower BP at 6 months postpartum. Subjects will undergo 3 study visits involving BP measurements, blood draws, questionnaires, and/or microiontophoresis. Up to 60 adult subjects will be enrolled at Magee-Women's Hospital.
