Thank you for posting your query.Spinal cord
does carry nerve
fibres 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.
