Scarring due to surgery on the male reproductive system or from infection and sexually transmitted diseases. Decrease in sperm production due to such conditions as Varicoceles (Varicose veins around the testes), hormonal disorders, diseases of the testicles, and obesity. Stress, smoking, drug or alcohol use, some medications, exposure to some toxins, malnutrition and being underweight. Some sexually transmitted diseases, such as Chlamydia and Gonorrhea
In Ayurveda, Oligospermia is compared to Napunsakata (impotency). It has four main causative factors - beejopghat (decrease in sperm quantity), old age and kshayaj (excessive loss of shukradhatu or reproductive tissue). The dosha involved in this condition is Pitta, which when imbalanced, leads to the loss of shukra.
