Abstract: Objective To evaluate the characteristics of the patients and effects of ovarian tissue cryopreservation in the first ovarian tissues cryopreservation bank in China. Methods The data of 217 female patients in the ovarian tissue cryopreservation database of Beijing Obstetrics and Gynecology Hospital (the first ovarian tissue cryopreservation bank in China) were statistically analyzed, including the diseases type characteristics, area, age distribution, and chemoradiotherapy received or not. Four specimens with diameter of 2 mm were taken from 46 patients, two of which were randomly selected for follicular count directly and the other two specimens were cryopreservation/thawing. The difference of follicular viability counts between the two groups was compared. Results The main disease type of ovarian tissue cryopreservation in Beijing Obstetrics and Gynecology Hospital is cervical cancer, accounting for 49.31%. The age group was mainly between 31 and 35 years old, accounting for 36.4% of the total number,following by age group between 26-30 years old, accounting for 25.3%. There was no significant difference in follicular viability between fresh tissue group and cryopreservation/thawing group (P>0.05). Conclusion The main diease type of ovarian tissue cryopreservation patients in Beijing Obstetrics and Gynecology Hospital is cervical cancer. Our ovarian cryopreservation technique can effectively preserve patients' fertility.
