Ultrasound imaging to assess cesarean scar damage
This trial tests a special ultrasound procedure (saline infusion sonohysterography) to help diagnose problems with the scar from a previous cesarean section. If you have symptoms like abnormal bleeding or trouble getting pregnant after a c-section, this imaging may help doctors understand what's happening.
Xi'an, ShaanxiAges 20–50 - NCT07603492Recruiting
Antibiotics for chronic endometritis and fertility
This study tests whether antibiotics can improve fertility in women with chronic endometritis—a long-term inflammation of the uterine lining that may prevent pregnancy. You would have a uterine biopsy to confirm the condition, receive antibiotic treatment, and be monitored to see if you become pregnant.
PragueAges 18–40 - NCT05978947Recruiting
Comparing two ways to prepare sperm for fertility treatments
This study compares two methods of preparing sperm for fertility treatments: a new microfluidic chip method and the standard density-gradient centrifugation method. It aims to find which method gives better sperm quality for procedures like IVF or ICSI.
Hong Kong, Hong KongAges Any age - NCT06023472Recruiting
Comparing sperm sorting methods for better genetic testing in IVF
This study compares two ways of preparing sperm for IVF (a microfluidic chip versus a centrifuge method). It aims to see which method leads to more genetically normal embryos (euploid) when doing PGT (pre-implantation genetic testing).
Hong Kong, Hong KongAges Up to 43 years - NCT06005311Recruiting
Comparing sperm preparation methods in IVF
This trial compares two ways of preparing sperm for IVF: a new microfluidic chip method versus the standard density-gradient centrifugation. It aims to see which method leads to more successful fertilizations and pregnancies.
Hong Kong, Hong KongAges Up to 43 years - NCT07556601Recruiting
Fast Freezing of Embryos for Future Use
This study tests a new, quicker way to freeze embryos (blastocysts) that are ready for use in future pregnancy attempts. It may help preserve embryo quality and improve success rates for people using donor eggs.
BarcelonaAges 18–50 - NCT07546552Recruiting
Egg Development Study: Testing a New Hormone Signal
This research study looks at how a specific hormone signal affects egg development in the ovary. Researchers are trying to understand if changing this signal might improve egg quality or fertility outcomes.
Skive, Midt JyllandAges 18 years+ - NCT07546435Recruiting
Male experiences with fertility treatment for low sperm quality
This study explores men's experiences undergoing ICSI, a fertility treatment that helps when sperm quality is reduced. Researchers want to understand how the treatment affects you physically and emotionally.
Skive, Midt JyllandAges 18 years+ - NCT07542626Recruiting
Restoring Fertility by Transplanting Frozen Testicular Tissue
This trial tests whether transplanting frozen testicular tissue that was saved before cancer treatment can help men who cannot produce sperm have biological children. The tissue is thawed and put back into the testicles to restore natural sperm production.
BrusselsAges 18–40 - NCT07535190Recruiting
PRP Treatment to Improve Uterine Lining for Fertility
This study tests whether platelet-rich plasma (PRP)—a concentration of healing cells from your own blood—injected into the uterus can improve the uterine lining and help embryos implant successfully during fertility treatment. Researchers will check how the treatment changes immune cells in the uterus.
Sofia, SofiaAges 18–50 - NCT07532629Recruiting
How Gut Bacteria Affect IVF Success in Couples
This study examines how the bacteria in your gut and your partner's gut may affect the success of IVF (in vitro fertilization) treatment. Researchers will collect samples and health information from couples before IVF to see if certain bacterial patterns predict better pregnancy outcomes.
