Vivian Adel Youssef, 18, from the village of Dafsh in Minya Governorate, married Hanna Emad on 19th April and moved to his village in Minya but has not been seen since she went to school.
Emad told the World Watch Monitor: "When I reached the school, I didn't find her there. Her mobile phone was switched off.
"I searched for her everywhere - in her school, in the nearby streets, in the hospitals of Samalut - but I didn't find her. I checked with her relatives and friends but none of them saw her that day."
While he has reported his wife missing to the police, Emad has not received any information about her so far.
Youssef's disappearance follows similar incidents that have left some family members fearing Christian women and girls are being abducted by Muslims with the aim of converting them to Islam to marry them.
Emad said that he did not believe his wife would run away from him.
He explained: "'There wasn't any dispute between us. I'm sure that Vivian was kidnapped.
"She is very religious and has a very strong relationship with God, and she loves me very much."
