Is a testicular biopsy a painful technique?

No. Open testicular biopsy or TESE (testicular sperm extraction) can be performed under local or general anaesthesia. The most common method is to sedate the patient so that they will not notice anything.

In percutaneous biopsy or TESA (testicular sperm aspiration), local anaesthesia is usually used, so the patient may feel some pressure but will not feel pain.
