Testicular biopsy

In a testicular biopsy (TESE), a small piece of testicular tissue is removed and sperm is extracted from it.

    As it is only possible to extract very few sperm cells in a testicular biopsy, it is almost always necessary to carry out a treatment with IVF and ICSI-techniques. Only with these techniques is it possible to achieve a fertilization of the oocyte with very few sperm cells.


    Reasons for a testicular biopsy:

    • Azoospermia: No sperm cells in an ejaculation
    • Aspermia: No ejaculation
    • Cryptozoospermia: Very few sperm cells in an ejaculation
    • Necrozoospermia: No live sperm cells in an ejaculation
