Abstract

Ovarian Tissue Cryopreservation (OTC) is a promising technique for reproductive preservation in women with cancer. Although this technique was applied successfully in many Invitro Fertilization (IVF) centers worldwide, OTC has not been developed in Viet Nam as well as there is no publication of OTC in Vietnam. The study of OTC by vitrification at IVFMD, My Duc Hospital was conducted from 2020 to 2023 with trial registration number NCT04666376. Ovarian tissues from each patient were divided into 3 groups, in which group 1 was fresh tissues as a control group, group 2 was vitrified tissues by Ova kit Type M (Kitazato, Japan) and group 3 was vitrified tissues by IVFMD medium. The findings showed the rates of viable follicles and follicles with both healthy oocyte and CGs in group 2 and 3 were significantly lower than in group 1, at [80.3% in group 1, 70% in group 2 and 65% in group 3] and [71.3% in group 1, 59.4% in group 2 and 58.3% in group 3] respectively (p < 0.05). The results aligned with previous findings because of the negative effects of cryopreservation. Moreover, it was illustrated that there was no change in the quality of tissue between the commercial medium and IVFMD’s medium in OTC.
