Evidence-based outcomes after oocyte cryopreservation for donor oocyte in vitro fertilization and planned oocyte cryopreservation: a guideline

Objective To provide evidence-based recommendations to practicing physicians and others regarding the efficacy of oocyte cryopreservation (OC) for donor in vitro fertilization planned OC. Methods The American Society Reproductive Medicine conducted a literature search, which included systematic reviews, meta-analyses, randomized controlled trials, prospective retrospective comparative observational studies published from 1986 2018. Practice Committee task force experts used available evidence through consensus developed guideline recommendations. Main Outcome Measure(s) Outcomes interest live birth rate, clinical pregnancy obstetrical neonatal outcomes, factors predicting reproductive outcomes. Result(s) search identified 30 relevant inform base this guideline. Recommendation(s) Evidence-based were likelihood births after OC, autologous OC infertile women, as well that may impact rates. Recommendations outcomes using fresh vs. cryopreserved oocytes cases or oocytes. Conclusion(s) There is insufficient predict rates On basis limited data, ongoing appear be improved women who undergo at younger older age. Although there are no significant differences per transfer with oocytes, rate same vitrified Neonatal similar compared Future compare cumulative needed.
