If the VA already service-connected your erectile dysfunction (also called ED, impotence, loss of use of a creative organ, low libido), it can cause or worsen other conditions that are ratable on their own. These "secondary" claims are where many veterans leave money on the table. Below is what a service-connected erectile dysfunction commonly leads to, why, and what evidence each one takes.
A secondary claim only works if the primary condition (erectile dysfunction) is already service-connected, and you have a nexus — a doctor's opinion that it is "at least as likely as not" the cause. Nexus letter sample and template →
Once ED is service-connected (even at a 0% schedular rating), the VA pays additional tax-free SMC-K for loss of use of a creative organ. Many vets stop at the 0% rating and miss this money.
What you'd need: Service connection for the ED itself (via the primary condition or its meds). No compensable percentage is required to trigger SMC-K.
ED can cause or worsen depression and anxiety and relationship stress, which the VA may recognize as a secondary mental health condition.
What you'd need: A mental health diagnosis and a nexus opinion linking the mood disorder to the ED. Granted less consistently; strongest with clear documentation.
