Phool Chandra, 35, and Ram Kali, 32, committed suicide Wednesday night at their home in Dariyabad town of Barabanki, some 35 km from Lucknow.
"Though no suicide note has been recovered, preliminary investigations indicate that the couple was in depression for not having any child, and therefore took the extreme step," police inspector SP Singh told reporters on Thursday in Barabanki.
"Despite trying various kinds of medical treatments, the couple could not conceive and used to tell locals they would soon end their lives," he added.
According to police, by the time locals reached the spot, the couple had died.
