Last month, U.S. District Judge David Hale found that the ban likely violated the U.S. Constitution.
However, he said he had to put his order on hold because the federal appeals court hearing the case recently paused a similar order in Tennessee.
The law is being challenged by families of transgender children who say they will be irreparably harmed by losing access to medical treatments.
The now-reinstated Kentucky and Tennessee laws were both blocked by federal judges on June 28 in response to lawsuits by families of transgender children.
The families say the laws discriminate against transgender people and take away parents' right to make medical decisions for their children.
