The Negative Effects of Consanguineous Marriage

For generations, certain negative customs have persisted among Arabs, one of the most prominent being consanguineous marriage—marriage between cousins or other close relatives. This practice, rooted primarily in tribal traditions, continues in many countries today.

What is Consanguineous Marriage?

Consanguineous marriage refers to a union between two people who are related by blood, such as cousins or maternal relatives. The specific term used varies depending on the degree of kinship. The main aim of such marriages is to preserve the family lineage and ensure the continuity of the family line.

Health Problems That May Result from Consanguineous Marriage:

Scholars have identified a number of health and psychological issues that can result from marrying relatives, including:

1. Genetic diseases, which vary from one family to another.
2. Congenital defects.
3. Single-gene disorders.
4. Severe physical disabilities that often arise only from consanguineous marriage.
5. Recurrent miscarriages.
6. Muscle atrophy in the face and jaw.

Reasons for Consanguineous Marriage:

Consanguineous marriage often occurs for a variety of reasons and goals that families and groups seek to achieve, such as:

• Keeping inheritance within the family.
• Passing down family traditions and culture to children.
• Accustoming children to the shared social customs of both spouses.
• Preserving lineage and religion.
• Expanding the family to gain social prestige.

Why Is Consanguineous Marriage Considered Risky?

Typically, siblings share a number of genes with their uncles and aunts—about a quarter of their genetic material—as well as other inherited traits. When both parents carry the same gene, it can manifest as a physical, mental, or psychological disorder. Scholars consider consanguineous marriage a significant risk to society if it becomes widespread within a single family.

Negative Effects of Consanguineous Marriage:

There are several negative effects that can result from consanguineous marriage, including:

• It opens the door to various genetic diseases.
• Conflicts between married relatives can destabilize relationships between both families.
• The occurrence of psychological disorders.
• The emergence of certain neurological and mental illnesses.
• Major social problems.

Important Considerations Before Entering into Consanguineous Marriage:

Scholars recommend several important steps that individuals should take before considering consanguineous marriage:

• Undergo comprehensive medical examinations and genetic testing to identify hereditary diseases.
• Avoid first-degree consanguineous marriages.
• Maintain privacy in the relationship to prevent family conflicts.

What Are the Advantages of Consanguineous Marriage?

Experts mention several potential advantages if a person marries a relative, including:

• The wife may be more attentive and caring toward her husband.
• It can strengthen family ties if the marital relationship is healthy.
• It fosters stronger relations between families.
• Children may feel a greater sense of social belonging due to the similarities between both sides of the family.
• Economic disparities that might arise from marrying into a different family are minimized.
• Couples who are relatives often have prior knowledge of each other's history and life, making interactions easier and more straightforward.

In conclusion, consanguineous marriage should be a conscious personal decision made after thorough consideration of all surrounding factors and ensuring that the family is free of hereditary diseases that could negatively affect children in the future.
