Intrauterine Insemination (IUI) is a fertility treatment that places sperm in the uterus during ovulation. During natural conception, sperm must travel from your vagina into your uterus and to your fallopian tubes (where the egg is waiting after ovulation). Only 5% of sperm make it from your vagina into your uterus and tubes. The fallopian tube is where the sperm and egg meet and fertilization occurs.
With IUIs, we can bypass most of this by placing sperm into the uterus and closer to the fallopian tube which increases the chances of fertilization. IUI can be done with a “fresh” sample from your partner or with frozen donor sperm. IUIs are typically timed around ovulation based on ultrasound or a positive reading on a digital ovulation predictor kit (OPK). IUIs can be helpful for couples with male infertility (erectile dysfunction, retrograde ejaculation, etc), lack of access to sperm (same sex couple or a single woman), or unexplained infertility. IUIs can be done with or without medication for ovulation induction.
