Ayurveda classifies these causes into Aharaja, Viharaja, Manasika, and Agantuja Nidanas, with Viharaja factors—particularly Vyayama (physical activity)—playing a significant role. Classical Ayurvedic texts emphasize that both Ativyayama (excessive exertion) and Avyayama (inactivity) can disrupt Agni and Dhatu balance, leading to Shukra and Artava Dushti, thereby impairing fertility. Modern research corroborates these insights, linking moderate exercise with hormonal balance and reproductive health, while associating extremes of activity with menstrual irregularities, anovulation, reduced sperm quality, and hormonal disturbances. This article bridges classical Ayurvedic concepts with contemporary evidence, emphasizing Yukta Vyayama (appropriate exercise) as a preventive and therapeutic strategy for infertility.
