IUI What is an IUI? An IUI (intrauterine insemination) is when sperm is prepared (washed) and placed within the uterus at the time of ovulation. IUI is used to treat infertility due to low sperm count, low motility, cervical mucus, and unexplained infertility. How do I Schedule My IUI?

Sperm is collected into a sterile container either at home or in one of our private collection rooms. If you are collecting at home, you still need an appointment to drop off your sample. The sample needs to be kept at body temperature during transportation and given to us within a 60-minute time period. If you cannot get the sample here within that time, please set up the appointment to collect the sample here. The sperm is then washed to concentrate the most motile sperm into a very small volume. The washed sperm is then placed into a catheter and passed through the cervix into the uterus. The insemination takes about 10 minutes to perform, then an additional 10 minutes is required so you can lie down.
