University of Newcastle reproductive expert John Aitken is hoping to stem abortion rates among the next generation of Australian women by developing a female contraceptive that paralyses sperm and protects from sexually transmitted diseases.

To date, Laureate Professor Aitken* has proven that the compound works in a test tube and has no toxic effects. He has also shown that it prevents the transmission of chlamydia.

The compound in said to be unique in that it is activated only on contact with semen. It doesn’t kill sperm but targets what enables it to swim.

“Our motivation is to reduce the amount of abortions, which are predominantly in under-19s,” Professor Aitken said. “I regard abortion as not a moral failure but a contraception failure. We just don’t have the right methods to empower women to control their fertility.”

Laureate Professor Aitken said that a fifth of pregnancies in Australia were aborted, resulting in about 70,000 terminations a year.

The trial compound is said to be safer for women.

“If you go to a chemist now and buy a spermicide, what you are buying is a detergent that was invented in the 1940s,” Laureate Professor Aitken said.

It’s called Nonoxynol-9 … and women who use it are more prone to getting HIV, not less prone, because of the damage the stuff does to their reproductive tract.”

Professor Aitken’s research also focuses on other aspects of reproduction, including male infertility. Last Sunday he addressed a public forum in Sydney titled “Making Babies in the 21st Century”.

“We have this strange dichotomy between people who are desperate to have pregnancies and those who are aborting their pregnancies,” he said.

“We need to understand this headlong rush into ART [assisted reproductive technology] is going to have a long-term impact on the health and well-being of future generations.

“Any woman who is going to put off having babies until after they’re 35 in the hope that IVF will rescue them are going to be drinking from the well of disappointment.”
