Hi . I take it this is something you have had an issue with. Mind if I ask if this occurred right away or a while after treatment? I ask because with radiation there is often a gradual damage and scar tissue around the glands that produce the seminal fluids (see here for more information: https://www.pcf.org/patient-support/side-effects/sexual-health/anejaculation/). I'm just wondering if your doctor may be able to identify the cause for you. Best, Richard (Team Member)
