Impotency, also known as erectile dysfunction, refers to the inability to achieve or maintain an erection firm enough for sex. It can be caused by physical factors like stress, poor lifestyle habits, or medical conditions, as well as psychological factors. Ayurveda sees impotency as being influenced by both the physical body developed from the union of semen and ovum, as well as the psyche or mind. The food consumed by the mother during pregnancy can impact if the child is born with impotent tendencies. Both genetic and psychological factors determine one's proclivity for impotency.
