Testicular biopsy is a simple surgical procedure performed on men diagnosed with azoospermia, i.e. the absence of sperm in the ejaculate. Thanks to testicular biopsy, it is possible to recover sperm that will be used in an in vitro fertilisation (IVF) treatment in order to have offspring.
For this reason, testicular biopsy is indicated in men with absent vas deferens, cystic fibrosis, seminal infections and even in men who have had a vasectomy. All these situations mean that it is not possible to expel spermatozoa in the ejaculate and, therefore, natural pregnancy would not be possible.
