If seeing a wife going through pain will get you to respect her more, then there is something seriously wrong in your thinking.
In many countries including mine, it is not the practice to allow husbands in the delivery room when the wife is undergoing labor. The experienced doctors, midwives and staff are there to take care of her in every way. Also, there are many "men" who may not be able to face the situation in the labor room, may swoon and collapse. What then? The doctor will then have "two" emergency situations to handle. --- one of them that was not required at all.
