Background: Fertility preservation is increasingly important with improving cancer survival rates and the delay in childbearing in modern societies. The objective of our study was to review the experience of the fertility preservation programme in a tertiary-assisted reproduction unit in Hong Kong. Methods: This is a retrospective study involving men and women who were seen at a tertiary-assisted reproduction unit for fertility preservation counselling before gonadotoxic treatment from January 2005 to December 2020. Their medical records in paper and electronic forms were reviewed. Results: There were 75 consultations for female fertility preservation from 2010 to 2020 involving 72 women. Twenty women underwent 22 cycles of ovarian stimulation for oocyte or embryo cryopreservation, two of whom subsequently transported their oocytes abroad for further management and another two achieved natural conception. Additional four women who did not have oocyte or embryo cryopreservation achieved natural conception after cancer treatment. Eleven (15.2%) women were followed up at a reproductive endocrinology clinic after their cancer treatment. From 2005 to 2020, 265 men had sperm cryopreserved. Twenty-six (9.8%) came back to use the cryopreserved sperms, the wives of 13 (50.0%) of whom achieved an on-going pregnancy. Six of them transferred out and 40 discarded the cryopreserved sperms. Conclusions: There was generally an increasing number of patient consultations for fertility preservation in our Centre over the past decade but a consistently low rate of utilisation of cryopreserved gametes for both women and men. Post-cancer treatment fertility evaluation and monitoring was a major area of deficiency in Hong Kong. More structured post-cancer treatment fertility follow-up is needed.
