Father-son incest: a case report.

A case of father-son incest is presented. There were three sexual involvements over a period of 6 weeks that ranged in activity from genital fondling to anal penetration. The father was the initiator of the activity and was drunk during each of the episodes. The son passively submitted while the mother denied the activity when told about it after the first episode. The marital situation had deteriorated over the years to an almost complete breakdown of communication. The father had been struggling with latent homosexuality for a long time, and the alcohol triggered the incidents. There was no evidence of any special relationship between father and son, except for the acting-out behavior and the challenging of parental authority by this particular son. Short term, behavior-oriented marital sessions helped to improve the situation at home.
