"By investigating their case..., it is clear that anti-revolutionary forces have falsely reported the charges by claiming each were sentenced to 10 years," the Islamic Republic judiciary's Mizan news agency said.
Mizan said the couple, bloggers Astiaj Haghighi and Amir Mohammad Ahmadi, received five-year terms each for "collusion against national security" by using their social media accounts, with one million followers, to stir protests in Iran.
It made no mention of an indecency charge.
HRANA said the couple had been charged with "spreading indecency" and with "collusion with the intention of disrupting national security".
Iranian authorities reported the sentencing of Haghighi and Ahmadi amid a wider crackdown on popular unrest touched off by the death of Kurdish woman Mahsa Amini after morality police arrested her for violating the country's Islamic dress code.
