What is the ruling on working in the programming of information systems for a fertility hospital that performs ICSI (intracytoplasmic sperm injection) and assisted reproductive procedures for married and unmarried individuals, including injecting a woman with the sperm of an unknown man?

If the predominant work of the hospital involves forbidden activities, then it is not permissible to work there except in cases of necessity. However, if the fundamental and predominant work of the hospital is permissible, and the forbidden work within it is incidental and minor, then there is no harm in working there, provided one does not directly engage in the forbidden activity.
