Qualité du gamète testiculaire

Testicular gamete quality

Résumé

Le recueil des spermatozoïdes testiculaires (TESE), suivi de la microinjection dans le cytoplasme ovocytaire (ICSI) a modifié radicalement la prise en charge des patients présentant une azoospermie sécrétoire. Cependant, les anomalies du processus spermatogénétique conduisent à s’interroger sur la qualité des gamètes recueillis au cours de la biopsie testiculaire quand on sait que le spermatozoïde est l’aboutissement d’une évolution séquentielle et programmée. Cette revue a pour objet:

  1. 1.

    De rappeler brièvement les modalités de synthèse des protéines constitutives du spermatozoïde;

  2. 2.

    De préciser les caractéristiques des spermatozoïdes prélevés dans le testicule;

  3. 3.

    D’évaluer l’incidence des anomalies nucléaires sur les résultats cliniques de I’ICSI.

Abstract

The combination of testicular sperm extraction (TESE) and ICSI has constituted a breakthrough in the treatment of men with nonobstructive azoospermia. However, impaired spermatogenesis raises the question of the quality of testicular spermatozoa obtained by testicular biopsy, when considering the male gamete as the product of a sequential and programmed spermatogenic process. The aim of this paper is: 1) To briefly recall the successive events of sperm protein synthesis; 2) To define the characteristics of sperm cells retrieved from the testis and 3) To evaluate the effect of nuclear anomalies on the outcome of ICSI.
