<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have chiari malformation have had 2 decompression surgeries.

Spinal cord does carry nerve fibers for erection and ejaculation. So, if there are significant damage to the cervical cod, losing erection is a possibility. However, since you are getting erection though not sustained, it could be related to psychological factors, stress, etc. A clinical examination would be helpful. Please get back if you require any additional information. Best wishes, Chat Doctor.
