Ovarian Tissue Vitrification as a Method for Ovarian Preservation in Women with Cancer: an Analysis of Granulose Cell Apoptosis
The aim of this study was to obtain the effective method of ovarian function preservation with granulose cell apoptosis assessment. Ovarian tissue vitrification became a method for ovarian function preservation in women with cancer. This technique can be done anytime without delay on cancer therapy, in prepubertal and unmarried patient. It also can store many primordial follicles. Ovarian tissue vitrification study is still limited to animal test and there was no data about apoptosis assessment after ovarian vitrification in human ovary. This is a quasi experimental study which was held in Department of Obstetrics and Gynecology Faculty of Medicine Universitas Indonesia - Dr. Cipto Mangunkusumo General Hospital and Fatmawati Hospital Jakarta from March 2012 to May 2015. Ovaries from thirteen women between 31-37 years of age who underwent oophorectomy with gynecological indication were examined. There were no difference morphologically between follicles from fresh and warmed-vitrified ovaries. The mean protein Bax expression on the fresh ovaries which assessed in the form of H-score was 1,66 ± 0,14 compared to 1,68 ± 0,13 on the warmed-vitrified grup (p = 0,165). The mean protein Bcl-2 expression on the fresh ovaries which assessed in the form of H-score was 1,73 ± 0,10 compared to 1,71 ± 0,10 on the warmed-vitrified grup (p = 0,068). As a conclusion, it was shown that vitrification did not affect Bax and Bcl-2 expression on human ovary.
