Egg collection and storage management costs were free for 3\u2009years after the project completed, and subsequent actual storage costs were borne by the individuals. After oocyte retrieval, we conducted a questionnaire on oocyte cryopreservation and administrative assistance.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Of the 62 seminar participants, 2 became pregnant naturally without oocyte retrieval. Oocytes were retrieved in 34 women (average age: 32.8\u2009years, number of oocytes obtained: 8.3), among whom 4 subsequently became pregnant and gave birth through natural pregnancy or artificial insemination, and 1 became pregnant and gave birth using frozen oocytes. In a follow-up questionnaire given to these 34 subjects, all responded that they were glad to have oocyte cryopreservation, but 23 subjects (67.6%) answered that they could not perform cryopreservation without financial assistance. Twenty-five participants (73.5%) wanted to try to conceive without using frozen oocytes as a post-cryopreservation plan.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>As a countermeasure against the declining birthrate, oocyte cryopreservation and associated workshops that can provide the information and education needed to conduct this task in a \u201cplanned\u201d manner may be useful in providing women with additional reproductive options.
