One reason men are the head of the home is the mood related problems some woman are known to experience at their time of the month. As women get older they experience menopause mood problems due to hormone related problems.
If a woman has an historectomy is it not much harder to control mood related problems even with hormonal medication. I personally would not want a woman pastor cause of the mood of the woman might flip over something trivial. But I'll grant you that its never trivial from a moody womans point of view.
