Intrauterine Insemination (IUI) is another form of assisted reproductive technology (ART).  With this technology sperm are put directly in the uterus during the time of ovulation, cutting down on the time and distance sperm have to travel. Many times fertility drugs are used to increase the number of eggs that can be ovulated and an hCG injection ("trigger shot") is used to make the woman ovulate. If the patient is going through a medicated IUI cycle, most likely they will be given fertility drugs such as Clomid (Clomiphene) or Letrozole (Femara) to stimulate their ovaries to produce multiple eggs. With this scenario, it is recommended to do electroacupuncture during day 3 and day 5 of taking the fertility drug. According to some studies, the pulsatility and resistance indices of uterine and ovarian arteries can be further reduced when electroacupuncture is added to a fertility drug treatment.
