Background:

• Multiple homosexual siblings in a single family are rare, with only one other documented case.
• This study examines a family with ten siblings, all experiencing some degree of homosexual behavior.

Purpose of the Study:

• To report on a family with multiple homosexual siblings and analyze potential etiological factors.
• To explore the role of early family dynamics in the development of homosexual adaptation.

Main Methods:

• Analysis of family dynamics, including parental behavior and sibling relationships.

Main Results:

• A hostile, violent, and alcoholic father contrasted with an affectionate, loving mother.
• One interviewed homosexual male sibling showed strong maternal identification and adopted a passive role in his homosexual marriage.

Conclusions:

• The findings support theories linking early family relationships to homosexual adaptation.
• Multiple homosexual sibling families offer valuable data for testing etiological theories of homosexuality.
