What does a Letrozole-Stimulated IUI Cycle involve?

This procedure combines oral medication (letrozole) with intrauterine insemination (IUI). You take letrozole tablets for 5 days early in your menstrual cycle to stimulate the ovaries to produce one or two mature eggs. Your doctor monitors follicle growth via ultrasound and blood tests, then triggers ovulation with an hCG injection. Approximately 36 hours later, a prepared sperm sample is placed directly into your uterus using a thin catheter—a quick, outpatient procedure.
