The primary goal is indeed to prevent premature ovulation, which could jeopardize the success of the cycle There is an emerging concept that suggests that the progesterone produced by the corpus luteum (formed after ovulation) might be sufficient to prevent further ovulation, obviating the need for antagonist or exogenous progesterone administration. This hypothesis relies on the natural regulatory mechanisms of the menstrual cycle to maintain a progesterone-dominated environment post-ovulation. We hypothesized that this approach would minimize treatment costs \u002Fburden without having an impact on the outcome.",[27,28],"Stimulation in the Ovary","IVF Outcome",[30,31,32,33],"progesterone","premature ovulation","ovarian stimulation","luteal stimulation","NOT_YET_RECRUITING","2026-05-06",{"date":37,"type":38},"2026-05-07","ACTUAL",{"date":40,"type":22},"2026-12-30",{"date":42,"type":22},"2027-12-30",{"name":44,"class":45},"ART Fertility Clinics LLC","OTHER",{"id":47,"slug":48,"hasResults":11,"nctId":49,"briefTitle":50,"officialTitle":50,"acronym":51,"eligibilityCriteria":52,"healthyVolunteers":16,"sex":17,"minAge":18,"maxAge":53,"enrollmentInfo":54,"targetDuration":4,"studyType":56,"phases":57,"briefSummary":59,"conditions":60,"keywords":67,"overallStatus":34,"whyStopped":4,"lastUpdateSubmitDate":70,"lastUpdatePostDateStruct":71,"startDateStruct":73,"completionDateStruct":74,"leadSponsor":76,"locationsCount":4},"100565054","phase-4-protocol-with-progestin-primed-ovarian-stimulation-ppos-from-the-beginning-of-stimulation-versus-protocol-with-gnrh-antagonists-for-ovarian-stimulation-in-patients-undergoing-duostim-with-embryo-accumulation-for-pgt-a-100565054","NCT06637189","Protocol with Progestin-primed Ovarian Stimulation (PPOS) from the Beginning of Stimulation Versus Protocol with GnRH Antagonists for Ovarian Stimulation in Patients Undergoing DUOSTIM with Embryo Accumulation for PGT-A.","PPDUO","Inclusion Criteria:\n\n* Regular menstrual cycles between 21 and 35 days, inclusive.\n* Indication of IVF with PGT-A.\n* Both ovaries present.\n* Ability to participate and complete the study.\n* Give and sign the consent to participate in the study.\n\nExclusion Criteria:\n\n* Endometriosis grade III\u002FIV\n* Concurrent participation in another study","43 Years",{"count":55,"type":22},144,"INTERVENTIONAL",[58],"PHASE4","The PPOS protocol (Progestin-primed Ovarian Stimulation) involves avoiding ovulation during ovarian stimulation with progesterone.
