Einfluss verschiedener klinischer Parameter auf die Erfolgsrate nachKryokonservierung imprägnierter menschlicher Eizellen

摘要: The Influence of Various Clinical Parameters on the Pregnancy Rates after Cryopreservation Human Prenuclear Oocytes It has been aim this work to examine ability human fertilized eggs in pronucleus state develop and implant under different clinical methodical conditions.(patients age, cause sterility, primary or secondary stimulation regimes, method fertilization, duration cryopreservation, number developmental stage embryos transferred). Patients with sterility conceived significantly less (7,5%) than those (15,2%). Patients, who had already pregnant once by artificial reproduction techniques (ART as IVF ICSI) also a higher chance conceive more another ART (15,4%). age women up 40 years was no significance concerning fertilizationand pregnancy-rate. Looking reasons for “idiopathic” most promising (pregnancy rate 14,9%) but there were only minor differences between male, female, organic functional causes. When both genders exhibited infertility, pregnancy decreased 6,7%. agents used eggsampling cycle showed some extend, namely 55,6% HMGstimulation contrast 63,1% FSH stimulation. survival thawing PN-cells lower HMG (60,2%) (67,7%). Otherwise did not show remarkable (9,6% bzw. 10,8%). pre-treatment cryotransfer very decisive, unmedicated spontaneous successful pregnancy-rate 15,7%. Clomipene-Citrate well low-dose Gonadotrophin application rather (14,3%)
