Age-specific probability of live birth with oocyte cryopreservation: an individual patient data meta-analysis.

ABSTRACT:

Objective

To estimate age-specific probabilities of live birth with oocyte cryopreservation in nondonor (ND) egg cycles.

Design

Individual patient data meta-analysis.

Setting

Assisted reproduction centers.

Patient(s)

Infertile patients undergoing ND mature oocyte cryopreservation.

Intervention(s)

PubMed was searched for clinical studies on oocyte cryopreservation from January 1996 through July 2011. Randomized and nonrandomized studies that used ND frozen-thawed mature oocytes with pregnancy outcomes were included. Authors of eligible studies were contacted to obtain individual patient data.

Main outcome measure(s)

Live birth probabilities based on age, cryopreservation method, and the number of oocytes thawed, injected, or embryos transferred.

Result(s)

Original data from 10 studies including 2,265 cycles from 1,805 patients were obtained. Live birth success rates declined with age regardless of the freezing technique. Despite this age-induced compromise, live births continued to occur as late as ages 42 and 44 years with slowly frozen and vitrified oocytes, respectively. Estimated probabilities of live birth for vitrified oocytes were higher than those for slowly frozen.

Conclusion(s)

The live birth probabilities we calculated would enable more accurate counseling and informed decisions for infertile women considering oocyte cryopreservation. Given the success probabilities, we suggest that policy makers should consider oocyte freezing as an integral part of prevention and treatment of infertility.

Project description:Study questionWhat is the live-birth rate (LBR) and cost-effectiveness of fertility preservation with oocyte cryopreservation (FP-OC) compared to expectant management in cancer patients age 25-40 based on estimated gonadotoxicity of treatments 5 years after cancer diagnosis?Summary answerOocyte cryopreservation prior to cancer treatment is more costly, yet more effective (producing more live births), than not undergoing oocyte cryopreservation but it is most beneficial for patients undergoing high-risk chemotherapy (HRC).What is known alreadyThe decision to undergo FP prior to treatment is multifactorial and can be costly and delay treatment. Not all treatments carry the same gonadotoxicity and patients may choose to undergo FP-OC based on the probability of premature ovarian insufficiency, predicted outcomes and cost. A comprehensive model that incorporates age at diagnosis and toxicity of treatment to help guide patients in the decision to undergo FP-OC does not yet exist.Study design, size durationThis study used a Decision Analysis Model to estimate effectiveness and cost of FP for cancer patients.Participants/materials, setting, methodsAge-based estimates of LBR and cost per live birth were calculated for ages 25-40 years based on gonadotoxicity of treatment. A decision analysis model was constructed using Treeage Pro 2015 with case base probabilities derived from national registries, practice guidelines and medical records from a national network of infertility practices (IntegraMed).Main results and the role of chanceCompared to no FP-OC, FP-OC improved LBRs for women of all ages undergoing either low-risk chemotherapy (LRC) or HRC; however, it was most cost effective for women undergoing LRC at older ages or HRC at younger ages. Although FP-OC results in higher LBRs, it was always more costly. Using donor oocyte IVF can be a successful alternative to autologous FP-OC.Limitations reasons for cautionDecision tree results reflect probabilities of certain events and are compiled from multiple reputable sources but are not directly derived from a recruited cohort of patients. Outcomes are based on United States estimates and should be interpreted in the broader context of individual patient diagnoses, treatment care plans and country of origin.Wider implications of the findingsThe development of this analytic model will help guide practitioners in their counseling of women from age 25 to 40 years, who are considering FP-OC at the time of cancer diagnosis. It provides a realistic pathway from diagnosis to LB and accounts for the majority of costs and outcome possibilities.Study funding/competing interest(s)This study was partially funded by a grant from National Institute of Health (NIH)/National Institute of Child Health and Human Development (NICHD) (R01 HD67683) to A.Z.S.

Project description:Study questionWhat are the chances of achieving a live birth after embryo, oocyte and ovarian tissue cryopreservation (OTC) in female cancer survivors?Summary answerThe live birth rates (LBRs) following embryo and oocyte cryopreservation are 41% and 32%, respectively, while for IVF and spontaneous LBR after tissue cryopreservation and transplantation, these rates are 21% and 33%, respectively.What is known alreadyCurrently, fertility preservation (FP) has become a major public health issue as diagnostic and therapeutic progress has made it possible to achieve an 80% survival rate in children, adolescents and young adults with cancer. In the latest ESHRE guidelines, only oocyte and embryo cryopreservation are considered as established options for FP. OTC is still considered to be an innovative method, while it is an acceptable FP technique in the American Society for Reproductive Medicine guidelines. However, given the lack of studies on long-term outcomes after FP, it is still unclear which technique offers the best chance to achieve a live birth.Study design, size, durationWe performed a systematic review and meta-analysis of published controlled studies. Searches were conducted from January 2004 to May 2021 in Medline, Embase and the Cochrane Library using the following search terms: cancer, stem cell transplantation, FP, embryo cryopreservation, oocyte vitrification, OTC and reproductive outcome.Participants/materials, setting, methodsA total of 126 full-text articles were preselected from 1436 references based on the title and abstract and assessed via the Newcastle-Ottawa Quality Assessment Scale. The studies were selected, and their data were extracted by two independent reviewers according to the Cochrane methods. A fixed-effect meta-analysis was performed for outcomes with high heterogeneity.Main results and the role of chanceData from 34 studies were used for this meta-analysis. Regarding cryopreserved embryos, the LBR after IVF was 41% (95% CI: 34-48, I2: 0%, fixed effect). Concerning vitrified oocytes, the LBR was 32% (95% CI: 26-39, I2: 0%, fixed effect). Finally, the LBR after IVF and the spontaneous LBR after ovarian tissue transplantation were 21% (95% CI: 15-26, I2: 0%, fixed-effect) and 33% (95% CI: 25-42, I2: 46.1%, random-effect), respectively. For all outcomes, in the sensitivity analyses, the maximum variation in the estimated percentage was 1%.Limitations, reasons for cautionThe heterogeneity of the literature prevents us from comparing these three techniques. This meta-analysis provides limited data which may help clinicians when counselling patients.Wider implications of the findingsThis study highlights the need for long-term follow-up registries to assess return rates, as well as spontaneous pregnancy rates and birth rates after FP.Study funding/competing interest(s)This work was sponsored by an unrestricted grant from GEDEON RICHTER France.

Project description:ImportanceAlthough multiple mechanisms have been proposed to explain the infertility related to endometriosis, there are no conclusive data on the association of endometriosis with endometrial receptivity. The oocyte donation model in assisted reproduction technology (ART) cycles can clarify this issue.ObjectiveTo explore the association of a history of endometriosis with ART outcomes in recipients of oocyte donation.Data sourcesIn this systematic review and meta-analysis, electronic databases were searched from inception until August 31, 2023, using combinations of relevant keywords. Moreover, we retrieved data from the databases of the Society for Assisted Reproductive Technology (SART) in the US and the Human Fertilization and Embryology Authority (HFEA) in the United Kingdom.Study selectionObservational studies were included if they investigated the impact of endometriosis on ART outcomes with donor oocytes.Data extraction and synthesisPublicly available data related to ART from various sources were gathered, and a retrospective aggregate and nonaggregate analysis using registries of in vitro fertilization cycles with oocyte or embryo donation was conducted.Main outcomes and measuresThe primary outcome was live birth rate (LBR) following oocyte donor cycles. The effect measures of comparisons between groups are presented as odds ratios (ORs) with a 95% CI.ResultsThis study analyzed 7212 oocyte donation cycles from 4 studies for the meta-analysis, along with 162 082 cycles from 2 registries (137 182 from SART and 24 900 from HFEA). No significant differences between the groups were observed in the meta-analysis of published data after adjusting for confounding factors (OR, 0.54; 95% CI, 0.19-1.57). A statistically significant lower LBR was identified in women with endometriosis when analyzing the aggregate data from SART and HFEA databases (OR, 0.89; 95% CI, 0.81-0.97).Conclusions and relevanceThis study found a modest decrease in LBR among women with a history of endometriosis, although only results from the pooled analysis of registry data and not those from the meta-analysis reached statistical significance. These findings suggest that a marginal impairment of uterine receptivity may contribute to infertility mechanisms in women affected by endometriosis.

Project description:IntroductionIntracytoplasmic sperm injection (ICSI) was introduced in 1990s as one of the most dramatic breakthroughs in assisted reproductive technology. Even with advances in ICSI technology, this mechanical micromanipulation carries a 5 to 19% risk of oocyte degeneration. Whether the presence of oocyte degeneration reflects the sibling oocyte quality and predicts the sibling embryo development potential and clinical pregnancy outcomes remains controversial. There is no study showing the competence of the sibling embryos from the prospective of cumulative live birth rate. Whether oocyte degeneration is associated with poor quality of the remainder of the cohort remains further to be elucidated.MethodThis retrospective observational study included a total of 488 OPU cycles underwent ICSI with fresh cleavage stage embryo transfer and successive frozen/thawed embryo transfer (FET) cycles from January 2018 to December 2019. All female patients were under the age of 35 years, and underwent ICSI with or without oocyte degeneration (OD). Cycles with at least one oocyte degenerated were defined as oocyte degeneration group (OD group), and cycles with no oocyte degenerated were defined as non-OD group. The OD group was further divided to three subgroups according to different oocyte degeneration rate (<10%, 10-20%, and >20%).ResultsThere were no significant differences with regards to implantation rate (38.5% vs 35.1%, P=0.302), clinical pregnancy rate (54.9% vs 50.3%, P=0.340), and LBR per OPU cycle (47.0% vs 42.9%, P=0.395) between OD and non-OD groups. Initial gonadotropin dosage, E2 level on hCG day and the number of matured oocytes appeared to be independent risk factors for OD. The adjusted odds ratio of live birth rate per OPU cycle were similar in different oocyte degeneration rate subgroups. The ongoing pregnancy/LBR per transfer in FET cycles was not significantly different between OD group and non-OD groups (38.8% vs 43.9%, P=0.439). The cumulative LBR per OPU cycle was also comparable between OD and non-OD group (63.4% vs 64.8%, P=0.760).ConclusionThe results provide cycle-based evidence that the presence of oocyte degeneration after ICSI is not an indicator for predicting the cumulative live birth rate per OPU cycle in young women.
