One in four women who have been clinically diagnosed as infertile can still conceive without undergoing treatments, indicating that they might just take a longer time to get pregnant.

The study, published in the journal Fertility and Sterility, observed Australian women aged 28 to 36 with a self-reported history of infertility.

Researchers found that a further 25% of those observed were able to conceive after undergoing fertility treatment, providing hope for women aged up to 36 years with fertility problems that they still have a chance at having a baby.
