Intrauterine Insemination (IUI)

IUI is one of the most non-invasive ways to get pregnant. The medications are typically pretty minimal, the effort involved is fairly quick, and the result can be the child you've been waiting for. But it does require you (and your partner, if applicable) to get involved in the process.

IUI, or Intrauterine Insemination, is a procedure where the sperm is placed directly into the uterus through the cervix using a small thin catheter. The sperm can either be from a donor from a sperm bank or a partnerís sperm. A semen specimen is collected by masturbation into a sterile collection cup. Semen collection kits are available upon request from the office.

If specimen is collected off premises then it must be transported to the andrology lab, keeping the specimen warm (body temperature, not any hotter), within 30 minutes of collection for best results (in general, sperm do not do well in plastic cups for long periods of time). It takes about an hour to wash, count and process the sperm sample prior to use for IUI.

Using donor sperm for an insemination would involve going through a sperm bank and having it shipped to PREG.

IUI is based on timing from either a positive ovulation predictor kit or by timing of injection of hCG.

  • If based on a urine ovulation predictor kit (OPK), the IUI is performed the morning after a positive response is detected. In some cases a hCG shot will be given the same day as a positive ovulation detection to help boost the process of ovulating.
  • If based on a hCG shot to trigger ovulation (no evidence of a positive urine ovulation detected), IUI is usually performed 24-36 hours after hCG shot is given. You will be instructed on when to give your hCG shot and arrive for your IUI by our staff.

IUI generally adds 3-5% pregnancy success rate to your treatments. IUI are generally done in combination with ovulation induction medications for best results.
