A study has been released by Auckland DHB’s Fertility Plus and the University of Auckland which shows the benefit of intrauterine insemination for unexplained infertility.

Although intrauterine insemination is often offered to couples with unexplained infertility, until now there have been no studies to highlight the benefit.

Professor Cindy Farquhar presented the results of the clinical trial at the European Society of Human Reproduction and Embryology Annual Meeting in Geneva on Monday.

The study reported that intrauterine insemination combined with clomiphene, a medication used to treat women who do not ovulate, was three times more effective than continuing to try and get pregnant without treatment. 

Professor Farquhar says: “This is the first clinical trial of intrauterine insemination with clomiphene citrate to show benefit. Previous studies either did not use ovarian stimulation or did not include women who were truly infertile.”

A total of 201 couples were involved in the study between March 2013 and May 2016.

Around 40 per cent of infertile couples have unexplained infertility, which means they have no obvious explanation for their delay in conceiving.
