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.

Comparing insemination timing 42 vs 36 hours after hCG injection
This trial tests whether waiting 42 hours after a hormone injection (hCG) before performing intrauterine insemination (IUI) leads to better pregnancy results than the standard 36-hour wait. It is for women or couples who are doing their first or second IUI and whose fallopian tubes are open.
