Semaglutide for better embryos in IVF for women with overweight or obesity
This trial tests whether semaglutide, a medication used for weight management, can improve the quality of embryos in women who are overweight or have obesity and are doing IVF. It aims to see if taking semaglutide before the IVF process helps make healthier embryos that can be frozen for later use.
Sabadell, BarcelonaAges 18–38 - NCT06896617RecruitingPhase 4
Corpus Luteum's effect on frozen embryo transfer pregnancies
This study looks at whether having a corpus luteum (the structure left after an egg is released) affects pregnancy outcomes in frozen embryo transfer cycles. It aims to help doctors choose the best way to prepare the body for embryo transfer.
Barcelona, SpainAges 18–41 - NCT07231510Recruiting
Chlordecone exposure and female fertility study
This study looks at how exposure to chlordecone, a chemical found in some Caribbean soils, might affect a woman's ability to get pregnant. You may be asked to share your medical history and provide samples to help us understand this link.
