Objective : To assess in-vitro fertilization rate of human oocytes at reproductive biology unit in Srinagarind Hospital
Design : A descriptive study
Setting : Reproductive biology unit, Srinagarind Hospital, Khon Kaen University, Khon Kaen, Thailand
Subject : Total of 476 human oocytes undergone in-vitro fertilization at Srinagarind Hospital between May 1993 to December 2004
Results : Total of 476 human oocytes were retrieved from 109 cycles of 89 patients. The average number of oocytes obtained per retrieval was 4.5 + 2.5. During the study period there were 376 mature oocytes collected (79.0 %). The fertilization rate detected in this study was 50.6 % of total oocytes or 73.3 % per treatment cycle. The clevage rate of the fertilized oocytes was 95.0 % and the embryo transfer rate was 92.2 % per cycles with successful fertilization.
Conclusion : This study demonstrated that in-vitro fertilization of human oocytes performed in Srinagarind Hospital had acceptable clevage rate and embryo transfer rate but the fertilization rate was rather low.
