The Leader first reported the ground-breaking research of Gavin Sacks in April 2006 and again in November 2007.

Dr Sacks, an English-born obstetrician/gynaecologist who holds a PhD in reproductive immunology, spent 10 years examining the link between high levels of cells found in a woman's uterus and female infertility.

He relocated to Sydney in June 2005 to take up a position at St George Hospital and further his research using the hospital's Flow Activated Cytometric Sorter to pinpoint natural killer cells taken from women during a blood test and uterus biopsy.

He found that 15 percent of women who previously suffered unexplained recurrent miscarriages had excessive levels of natural killer cells.

Further research revealed high levels of natural killer cells in about 10-15 percent of women whose IVF attempts repeatedly failed.

Dr Sacks then devised a treatment protocol to control the levels of naturally occurring cancer and infection-fighting white blood cells by suppressing the women's immune system.

The drug treatment has since been fine-tuned to a "moderate'' dose of a common steroid.

Dr Sacks' research has recently gained national and international attention. He featured on an episode of 60 Minutes last month, while a major scientific paper detailing his research was also published in the October edition of Human Reproduction.

About 700 women have undergone the two-part test in the past four years. In that time, 50 babies have been born to women after they underwent the drug treatment.

"These are people who have been trying for many years stories that you just cannot believe,'' he said.

"Recurrent, unexplained miscarriage is quite frustrating and stressful.''

Dr Sacks is now preparing to begin a large clinical trial in a bid to gain conclusive scientific proof to support his theory. In the meantime, he will continue to offer the test and "experimental'' treatment at St George Hospital and IVF Australia Southern Sydney, Kogarah.

Dr Sacks will be guest speaker at an

information session to launch IVF

Australia's new clinic at 46-48 Urunga Parade, Miranda.

The one-hour information session will be held at 6.30pm next Wednesday,
