为避免对下一代的影响,何时是癌症患者冷藏精子的最佳时间?在匹茨堡大学召开的男性在化疗期间的发育毒性的首次国际会议上对此问题展开了讨论。一些遗传学家和毒理学家极力主张在化疗或放疗开始前。他们认为在化疗期间产生的精子导致下一代出现畸形的危险性要比正常高,但另一些科学家认为目前尚无足够的科学依据能证实此看法。 To avoid the impact on the next generation, when is the optimal time for cryopreservation of sperm in cancer patients? This issue was discussed at the first international conference of men at developmental toxicity during chemotherapy at the University of Pittsburgh. Some geneticists and toxicologists strongly advocate chemotherapy or radiotherapy before the start. They believe the sperm produced during chemotherapy is at a higher-than-normal risk of deformities in the next generation, but others do not believe there is enough scientific evidence to confirm that.
