What is the best time for IUI?

July 24, 2018

An IUI or Intrauterine insemination is a procedure where the sperm is injected directly into the uterus using a thin and flexible catheter. It is a very short procedure and can be done within a few minutes. Before the IUI, first, the semen sample is collected and washed before the insemination. However, after the washing, IUI must be done as soon as possible.

The best time for IUI Procedure

IUI treatment is the basic treatment for most subfertile couples. They have at least one fallopian tube, an ovulatory cycle, and the required amounts of spermatozoa. Since timings is a major factor for IUI, the Cochrane researchers tried to figure out if there was a one-timing technique, which could have better results. They conducted 18 random trails with different timings but were unable to reach a conclusion and had insufficient results to publish their findings. But today, after several trials and errors, the researchers concluded that IUI must be conducted before 6 hours on either side of ovulation. If the time is based on the HSG injection, it can be done between 24 hours to 48 hours later and if two IUI’s are scheduled, it is gone with a gap of 24 hours.

Is IUI Process Painful?

Most women say that IUI is a painless technique. It is almost similar to a pap smear. But yes, one might experience a few cramps post IUI.

After IUI Procedure

Once your IUI is complete, it is important that you lie down for at least 15-30 minutes and take it easy. It is also important to take bed rest on that day and say away from heavy lifting and intense workouts.
