Intrauterine Insemination or IUI – Donor or Frozen Sperm

Intrauterine Insemination, also called IUI or artificial insemination, is the process of placing the best sperm inside the uterus. This procedure improves the chances of a pregnancy. If sperm is deposited in the vagina, only about 20% of sperm make it into the uterus and up into the tubes. Through IUI, 100% of the best sperm make it into the uterus and up to the tubes. For a frozen specimen, expect to wait up to 45 minutes for your sperm to thaw and a semen analysis done to evaluate how well the sperm survived that thaw.

Hours for donor fresh or frozen inseminations:

M-F: 7:30-11:00 am.
S-S: 8:00 – 9:00 am.

Before the Procedure

Make sure you know your donor sample number (if applicable). We will only release the sample if you know the number! Try to maintain a full or partially full bladder.  We suggest you drink 16 ounces of liquid 30 minutes before the procedure.

What to Expect

During the procedure, a tiny tube will be placed into your vagina, through your cervix, and then into the uterus. The sperm will be placed into the uterus through this tube. Although most women say they feel nothing, there may be some cramping at the time of injection of the sperm. The total procedure will take about 15 minutes.


Sterile gloves and tubes are used to minimize the risk of infection.  If you are using a directed (or known) sperm donor, you will be notified of the screening and testing results required by the FDA and will sign a form summarizing this information.

After the Procedure

After the insemination, you will be asked to lie down for about 10 minutes. After that time, you will be able to return to your daily routine.

Semen Count Results

You will be given the amount of total swimming sperm at the time of the insemination.  You will also be informed as to how this count relates to pregnancy rates.

When to Call our Office

Plan on testing for pregnancy 17 days after the Ovidrel shot.  With a positive pregnancy test, we suggest confirming the results with a blood test.  If you get your period, please call our office to discuss next steps.

Call immediately if you experience:

  • Cramping lasting longer than one hour
  • Bleeding that fills more than one pad per hour
  • Fever of 100°F or higher or chills
