Abdul Kareem al-Rimawi became a father for the first time on Wednesday, despite currently serving a 25-year jail sentence in an Israeli prison.
His wife Lida, 34, gave birth to a healthy baby boy weighing 2.8 kg at the Razan Medical Center in Nablus.
Majd was conceived at the Razan clinic by IVF using sperm smuggled from her jailed husband, in the second such birth of its kind.
Al-Rimawi has spent 12 years in jail, and will be imprisoned until 2026.
Last year, Dalal Rabayaa, 31, gave birth to a baby boy at the Razan Medical Center after smuggling her husband's sperm out of prison and using IVF treatment to become pregnant.
She declined to give details of how the sperm was smuggled, citing security concerns.
"This accomplishment is dedicated to the Palestinian people, namely prisoners and their families," she said at the time.
There are currently 16 women who have become pregnant by smuggling their husband's sperm from Israeli jails, medical sources told Ma'an.
