Clinical trials will be undertaken in Australia to test the world's first female "Viagra", which experts say could boost the sex drive of one in three women.
The product, Tefina, is a testosterone gel that researchers say could boost female sexual arousal and satisfaction.
The gel is sprayed up the nose, where the testosterone is absorbed within minutes and the effects could be felt within hours.
"Female sexual dysfunction is a real thing and we think up to 43% of women suffer some form of sexual dysfunction," said Dr Fiona Jane of Melbourne's Monash University
Australian researchers are looking for about 100 women aged between 18-49 to take part in the trial, including women in the United States and Canada.
But some experts doubt whether the gel would be the whole answer.
"Men use sex to de-stress and women need to be de-stressed to have sex, so that's a very complex emotional issue," said fertility expert Dr Ric Gordon.
"Now, whether particular nasal spray can fix that problem remains to be seen."
Men's Viagra is a world-wide hit, with US sales currently topping US$2 billion (NZ$2.4 billion) a year.
"A lot of people have thought that drumming up the idea of a female 'Viagra' is just for pharmaceutical companies," said Dr Jane. "In fact, there is a huge need for women to have their sexual dysfunction addressed."
This is good news for many women interviewed by ONE News Australia correspondent Steve Marshall.
"I think that would be a great idea," says one. "I know my husband would."
"Yeah, why not. I'd like to see what it would do for me," said another.
But some women have reasons to avoid the gel.
"No, why not? Cos it would result in more kids."
If the trial is successful, the drug could be available within 3-5 years.
