Why Same-Gotra Marriage Is Considered Forbidden
The ancient text Manusmriti lays down guidelines for marriage. It states:
“A girl who does not belong to the six maternal generations and is not of the father’s gotra (lineage) is suitable for marriage among the twice-born classes.”
In other words, marriage is considered proper only when the bride does not share close maternal ancestry within six generations and does not belong to the same paternal gotra as the groom.
Scientific Perspective
Modern medical research has shown that marriages within the same gotra (lineage) can lead to a higher risk of genetic disorders in children. Studies indicate that such unions are more likely to result in:
- Primary infertility in couples
- Congenital disabilities in offspring
- Developmental delays and mental impairment
- Higher rates of miscarriage and infant mortality, both during pregnancy and shortly after birth
- Increased incidence of congenital heart defects
- Reduced likelihood of twin births
Research Findings
A study conducted at Sarojini Devi Eye Hospital in Hyderabad revealed that children born from same-gotra marriages are more prone to eye diseases. The research found that out of 200 children from such unions, at least one child suffered from an eye disorder.
