ABSTRACT
OBJECTIVE:
To comprehensively analyze the status quo of autologous sperm preservation in the human sperm bank in Beijing and better utilize the existing resources for the preservation of male fertility.METHODS:
We retrospectively analyzed the geographical data and semen quality of 251 males with autologous sperm preservation in the Human Sperm Bank, Science and Technology Research Institute, National Health and Family Planning Commission of China from July 2006 to December 2016.RESULTS:
The rate of autologous sperm preservation in the Human Sperm Bank was as low as 8.76% between July 2006 and December 2010 but increased annually by 119% on average from 2011 to 2013. Of the 251 males involved, 204 (81.27%) were aged 20ï¼39 years, 175 (69.72%) had bachelor's or master's degree, 223 (88.84%) had no child, 69 (27.49%) got less than 10 tubes of semen samples frozen, and 26 (10.36%) had their semen samples cryopreserved only once. The utilization rate of the cryopreserved sperm was only 5.58 % (n = 14). The main reason for autologous sperm preservation was carcinoma (55.78% ï¼»n = 140ï¼½), including blood cancer (22.31% ï¼»n = 66ï¼½), testicular cancer (13.15% ï¼»n = 33ï¼½) and other cancers (16.33% ï¼»n = 41ï¼½). Compared with the non-cancer males, the cancer patients had a significantly reduced mean sperm concentration (90.45 vs 60.53 ×106/ml, P < 0.05), total sperm count (311.3 vs 175.8 ×106, P < 0.05), percentage of progressively motile sperm (PMS) (49.21% vs 43.55%, P < 0.05) and recovery rate of PMS (68.13% vs 52.17%, P < 0.05). In the subgroups of testicular, blood and other cancers, the sperm concentration averaged 37.68, 57.98 and 90.69 ×106/ml, the semen volume 2.73, 2.82 and 3.41 ml, the total sperm count 93.29, 158.41 and 349.49 ×106, the percentage of PMS 45.32%, 43.47% and 44.49%, and the recovery rate of PMS 48.32%, 50.07% and 61.09%, respectively, the sperm concentration and total sperm count significantly lower in the testicular cancer patients than in the other two groups (P < 0.05).CONCLUSIONS:
The number of the cases of autologous sperm preservation in Beijing is increasing year by year, and the majority of them are cancer patients. As most of the cancer patients have missed the best period for sperm preservation, sperm bank workers should endeavor to increase the public awareness of autologous sperm preservation.Palavras-chave
