A Queensland woman has won the right to use her dead boyfriend's sperm to have children.

Brisbane Supreme Court justice Sue Brown handed down her landmark decision on Wednesday.

She determined Ayla Cresswell should be able to use Joshua Davies' reproductive tissue but said it was up to the particular medical clinic to decide if it was satisfied to go ahead with the procedure.

The decision will set a legal precedent in Queensland for women seeking to use the sperm of their late partners to have children.
