Do fathers really need to be in the delivery room during the birth of their children?

Personally. I want my husband to be with me when i deliver our baby soon. But we didnt know yet if the LR procedure allows husband to be in LR with the wife. Plus, i didnt know if my husband can resist the hectic and panic inside LR. Didnt quite show during other time so we decided to let him be with me inside LR but if he cant stand the panic-hectic/having weak knees, i think its okay if he want to wait outside.
