Siddha medicine views health as a balance between three fundamental bodily humors or doshas: Vatha (air), Pitha (fire), and Kapha (water). Infertility is believed to occur when there is an imbalance in these humors, leading to issues in the reproductive system. The causes of infertility in Siddha can be linked to various factors such as improper diet, lifestyle, mental stress, and environmental influences that disturb the balance of Vatha, Pitha, and Kapha. Treatment in Siddha aims to restore this balance through dietary regulations.
