<p>Cultural beliefs on the marriage system and reproductive health impact women’s health universally in tribes. The Tamil Toda community’s marriage in the aspects of women’s reproductive health remains understudied. They are one of the oldest ethnic groups in India, in which pregnancy before marriage and paying fine as buffalo by the bride’s family for not getting pregnant in a period after the engagement made this research a case study. According to the research design, we conducted 2 in-depth interviews and 1 focus group discussion to describe the depth of marriage dynamics in their traditions. The findings through the lens of cultural beliefs are that reproductive health is associated with physical, mental, and social well-being, so violating biological norms can have serious consequences, such as intangible pain, health complications, and economic loss. Thus, it suggests that reproductive health, medical advancements, and healthcare systems should be considered along with the gender inclusivity, as infertility involves multiple biological realities. In conclusion, inclusive policies integrate science and culture to create a true value system, fostering an effective and harm-free indigenous ethnic society.</p>
