Fertility preservation outcomes (survey responses per center)

How many cryopreserved patient oocytes would be sufficient for you to recommend that further treatment cycles are not necessary, if the general condition of the patient would allow her to continue cryopreservation therapy?
1–5	6–10	11–15	More than 15	I do not have experience in the field
18 (5.6%)	51 (15.9%)	107 (33.3%)	120 (37.4%)	25 (7.8%)
Statement: the success rate of fertility preservation is not yet good enough to make it an available option.
Agree	Neither agree nor disagree		Disagree
30 (9.3%)	46 (14.3%)		245 (76.3%)
Were there pregnancies in your center in the following situations? (multiple answers allowed)
After cancer treatment from frozen embryos	After cancer treatment from cryopreserved oocytes	After fertility preservation from transplanted ovarian tissue	I am not aware of any pregnancies	There were no pregnancies in women with the situations stated above
182 (56.7%)	117 (36.4%)	31 (9.7%)	57 (17.8%)	55 (17.1%)
The pregnancy rate after oocyte cryopreservation in cancer patients is not yet known because
There are not enough patients that benefit from this procedure who have gotten as far as embryo transfer to assess the pregnancy rate	The ability of cryopreserved oocytes to be fertilized is impaired	There is no proper registry	Other reasons
142 (44.2%)	15 (4.7%)	136 (42.4%)	28 (8.7%)
