Varicocoele treatment will only treat conditions associated with varicocoele. Namely if you are having scrotal pain and discomfort. It will not have any effect on testosterone
, libido or erection or voiding symptoms.
It is expected for a 65 year old to have voiding difficulties, ED, and loss of libido due to age and decreasing testosterone. Fortunately we have medicines that can be used to improve your symptoms. I hope i have answered your question.
