Mature oocytes underwent intracytoplasmic sperm injection (ICSI), whereas immature oocytes were cultured in\u00a0vitro for maturation before ICSI. A total of 13 oocytes were fertilized, five embryos were cryopreserved, and one embryo transfer resulted in a biochemical pregnancy. At age 28, a second OTO\u2010IVM using dibutyryl\u2010cyclic AMP (dbcAMP)\u2010enhanced biphasic IVM produced seven germinal vesicle oocytes; three matured to metaphase II, two fertilized, and one cleavage\u2010stage embryo led to a live birth at 39\u2009weeks of gestation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This is the first documented live birth following dbcAMP\u2010enhanced biphasic IVM of ovarian tissue\u2010derived oocytes.
