Nicht signifikant mehr Mädchen nach IMSI!
Kürzlich berichtete eine Arbeitsgruppe (Setti et al. Gender incidence of intracytoplasmic morphologically selected sperm injection-derived embryos: a prospective randomized study. Reprod Biomed Online. 2012 Apr;24(4):420-3), dass signifikant mehr weibliche Embryonen nach intrazytoplasmisch morphologisch selektierte Spermieninjektion (IMSI) entstehen würden, verglichen zu der herkömmlichen intrazytoplasmischen Spermieninjektion (ICSI). Die Autoren kommen zu folgendem Schluss - Zitat: ‘‘alterations in the Y chromosome may lead to morphological changes that would prevent spermatozoon selection under high magnification‘‘. Beobachtungen aus drei IVF Zentren in Österreich (IVF Zentren Prof. Zech) (hier wird die IMSI Technik schon seit 6 Jahren angewendet) und Frankreich, zeigen keinen Unterschied in der Verteilung der Geschlechter bei Kindern die mit Hilfe der IMSI Behandlung geboren wurden und widersprechen den Ergebnisse von Setti und Mitarbeitern. Insgesamt wurden 1852 Babys nach IMSI geboren. Davon waren 949 (51,2%) weiblich und 903 (48,8%) waren männlich. Ein ähnliches Ergebnis wurde beobachtet unter Babys geboren nach ICSI: 439 (50,6%) von 867 Babys waren Mädchen und 428 (49,4%) Knaben. Keiner der Unterschiede in der Verteilung bei den Geschlechtern war statistisch signifikant! Die wissenschaftliche Arbeit finden Sie unter:
