Use of testicular spermatozoa in non-azoospermic patients.
The aim of the study is to evaluate the characteristics of couples whose male partner is offered TESE after the failure of previous ICSI technique performed with ejaculated semen. All couples in a third-level University affiliated centre, between January 2010 and January 2020, whose male partner were diagnosed with any type of oligospermia and underwent TESE after ICSI from ejaculated semen, were included in the analysis.

| Testicular sperm extraction (TESE) | Procedure | During the procedure, the testis is exposed through a small incision and one or more biopsies are taken blindly. A vertical incision is made in the median raphe, skin, dartos and tunica vaginalis to expose tunica albuginea. The tunica albuginea is incised for about 4 mm at upper pole near the head of epididymis. |
