Prognostic factors for the success of obtaining spermatozoa with a biopsy of testicular tissue in men with severe forms of pathozoospermia

Abstract

The article presents the results of a survey of men with azoospermia and severe oligozoospermia, with and without microdeletion of the long arm of the Y chromosome, as well as the results of a testicular biopsy. The absence of deletions of the AZF region, the absence of testicular hypoplasia, as well as normal levels of FSH, LH and inhibin B are prognostically favorable criteria for the success of obtaining spermatozoa with a biopsy of testicular tissue for in vitro fertilization (IVF).
