CURRENT TECHNIQUES
Timed Intercourse (IC) or Cycle Monitoring This is a technique using ultrasound scans, blood and urine tests to accurately pin point if and when ovulation is occurring. It will require 2 to 4 visits to the Centre on average, over a two week period. All the investigations are bulk-billed. Ovulation Induction (OI) This is a technique using ultrasound scans, blood and urine tests to accurately pin point if and when ovulation is occurring. It will require 2 to 4 visits to the Centre on average, over a two week period. All the investigations are bulk-billed. This is a treatment that uses medications, either tablets or injections, to stimulate the ovary to produce a mature egg. It is suitable if the only fertility problem is a lack of spontaneous ovulation. Tablets such as clomiphene or bromocriptine are taken where appropriate. However, often by the time a couple come to a fertility unit, these medications have already been tried unsuccessfully. Hormonal injections are given which mimic the hormones your brain produces to stimulate an egg to grow. As it is important that only one egg grows to maturity, careful monitoring using ultra sound scans, blood and urine tests is done. The amount of time involved will depend on how quickly the ovaries respond and whether the woman has polycystic ovaries. Polycystic ovaries are more likely to over or under respond and therefore it might take some weeks before ovulation successfully occurs. We expect a pregnancy rate of 15 to 40%, depending on the woman’s age. Artificial Insemination using Partner’s Semen (IUI) This is a treatment that combines a small amount of ovarian stimulation, to maximise the maturity of the egg and the lining of the uterus, with intrauterine insemination of the best of the sperm from a man’s ejaculate. It is suitable for couples with unexplained infertility or minor semen problems provided the woman’s fallopian tubes are normal. The aim is to maximise the number of normal, motile sperm...
