Comparing reproductive outcomes between conventional in vitro fertilization and nonindicated intracytoplasmic sperm injection in autologous embryo transfer cycles: a Society for Assisted Reproductive Technology Clinic Outcome Reporting System Study.

ABSTRACT:

Objective

To compare clinical outcomes between nonindicated intracytoplasmic sperm injection (ICSI) and conventional insemination.

Design

Autologous cycles performed from 2014-2017 were identified, excluding frozen oocyte cycles. Outcomes were compared between conventional insemination (in vitro fertilization [IVF]) and nonindiated ICSI and analyzed separately for fresh, frozen-thawed preimplantation genetic testing (PGT) and frozen-thawed non-PGT cycles.

Setting

US-based fertility clinics reporting to the Society for Assisted Reproductive Technology.

Participants

A total of 187,520 patients underwent 318,930 cycles, 57,516 (18.0%) using conventional IVF and 261,414 ICSI (82.0%).

Interventions

Intracytoplasmic sperm injection, with or without indications (male factor, prior fertilization failure or any PGT [2012 recommendations]/single-gene PGT [2020 recommendations]).

Main outcome measures

Odds ratios (ORs) for live birth rates and clinical pregnancy rates were calculated after multivariable adjustment for maternal age, body mass index, infertility etiologies, prior IVF births, and number oocytes retrieved.

Results

Intracytoplasmic sperm injection was indicated in 151,627 (58.0%) of cycles according to 2012 American Society for Reproductive Medicine Practice Committee recommendations, and 108,895 (41.7%) according to 2020 recommendations. In multivariable models, nonindicated ICSI among fresh cycles was associated with reduced odds of completing a blastocyst-stage transfer (OR, 0.72; 95% confidence interval [CI] [0.7, 0.75]; P<.001), resulting in reduced odds of live birth (OR, 0.80; 95% CI [0.78, 0.83]; P<.001). Among completed fresh transfers, clinical pregnancy and live birth rates were comparable between nonindicated ICSI and IVF. Nonindicated ICSI in frozen-thawed cycles with PGT and without PGT was associated with comparable live birth and clinical pregnancy rates with IVF in multivariable models.

Conclusion

Nonindicated ICSI was associated with reduced blastocyst availability in fresh cycles compared with IVF, leading to lower live birth rates. Outcomes from completed transfers were clinically comparable.

Project description:BackgroundThe impact of donor sperm on pregnancy outcomes is controversial. The aim of this study was to investigate whether donor sperm in in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) treatment could reduce the rate of live births or increase the incidence of adverse pregnancy outcomes and birth defects in neonates.MethodsThis single-centre, retrospective cohort study included 1,559 patients with infertility who received donor sperm at our hospital from 2015 to 2019. All the patients received fresh embryos and underwent first-cycle transfer. After propensity score matching, 4,677 controls who received their partners' sperm were matched at 1:3. Clinical pregnancy, perinatal, and neonatal outcomes were compared between the donor sperm and partner sperm groups.ResultsThe embryo development was better in the donor sperm group than in the partner sperm group. The high-quality embryo and available embryo rates were significantly higher in the donor sperm group (P<0.05 for both groups). The rate of high-quality embryos transferred from the donor sperm group was higher than that from the partner sperm group (P<0.05). The clinical pregnancy (62.99% vs. 59.65%; P=0.02) and live birth (54.65% vs. 51.59%; P=0.036) rates were higher in the donor sperm group. After adjusting for confounding factors, no significant difference in live birth rates was observed between the two groups (adjusted P=0.057). The low birthweight (18.21% vs. 21.39%; P=0.023) and small for gestational age (SGA) (7.60% vs. 11.97%; P<0.001) rates were lower in the donor sperm group. To exclude the effect of multiple pregnancies, we evaluated neonatal outcomes of singleton pregnancies. No significant differences were noted in preterm and very preterm birth, SGA, mean birthweight, high birthweight, and low birth weight (LBW) and very low birth weight (VLBW) rates (P>0.05 for both groups). Further, no significant between group differences were observed in the ectopic pregnancy rate, early and late spontaneous abortion rates, gestational age, rate of large for gestational age (LGA), and neonatal defects.ConclusionsCompared with partner sperm, donor sperm did not reduce live birth rate and did not increase neonatal LBW or low birth defects.

Project description:Background and Objectives: Although considerable research has been devoted to examining the distinctions between fresh and frozen embryo transfer regarding obstetric outcomes and rates of pregnancy success, there is still a scarcity of thorough analyses that specifically examine neonatal outcomes. The objective of our study was to provide an in-depth analysis of neonatal outcomes that occur after the transfer of fresh and frozen embryos (ET vs. FET) in IVF/ICSI cycles. Materials and Methods: Multiple databases (PubMed/MEDLINE, Cochrane Library, Web of Science, Wiley, Scopus, Ovid and Science Direct) were searched from January 1980 to February 2024. Two reviewers conducted the article identification and data extraction, meeting inclusion and exclusion criteria. The methodological quality was evaluated using the Newcastle-Ottawa Scale (NOS) or the revised Cochrane Risk of Bias Tool. The meta-analysis was performed using RevMan 5.4. Results: Twenty studies, including 171,481 participants in total, were subjected to qualitative and quantitative analyses. A significant increase in preterm birth rates was noted with fresh embryo transfer compared to FET in the overall IVF/ICSI population (OR 1.26, 95% CI 1.18-1.35, p < 0.00001), as well as greater odds of a low birth weight (OR 1.37, 95% CI 1.27-1.48, p < 0.00001) and small-for-gestational-age infants in this group (OR 1.81, 95% CI 1.63-2.00, p < 0.00001). In contrast, frozen embryo transfer can result in macrosomic (OR 0.59, 95% CI 0.54-0.65, p < 0.00001) or large-for-gestational-age infants (OR 0.64, 95% CI 0.60-0.69, p < 0.00001). No significant difference was observed regarding congenital malformations or neonatal death rates. Conclusions: This systematic review confirmed that singleton babies conceived by frozen embryo transfer are at lower risk of preterm delivery, low birthweight and being small for gestational age than their counterparts conceived by fresh embryo transfer. The data support embryo cryopreservation but suggest that elective freezing should be limited to cases with a proven indication or within the framework of a clinical study.

Project description:BackgroundVarious luteal phase supports (LPSs) have been proven to increase the pregnancy rate in fresh cycles of in vitro fertilization or intracytoplasmic sperm injection; however, there is still significant debate regarding the optimal use of LPS.MethodsA systematic review with the use of a network meta-analysis was performed via electronic searching of Ovid MEDLINE, the Cochrane Library, Embase, Web of Science, ClinicalTrials.gov and Google Scholar (up to January 2021) to compare the effectiveness and safety of various LPSs, as well as to evaluate the effects of different initiations of LPSs on pregnancy outcomes. The primary outcomes included live birth and ongoing pregnancy, with the results presented as odds ratios (ORs) with 95% confidence intervals (CIs).ResultsEighty-nine randomized controlled trials with 29,625 women comparing 14 interventions or placebo/no LPS treatments were included in the meta-analyses. No significant differences were found in terms of the pregnancy outcomes when LPS was started within 48 h after oocyte retrieval versus a delayed initiation between 48 h and 96 h after oocyte retrieval. The addition of gonadotropin-releasing hormone (GnRH) agonists to progesterone vaginal pessaries showed a significant benefit in terms of live birth (OR 1.39, 95% CI 1.08 to 1.78). Only human chorionic gonadotropin (HCG) was found to be more efficacious than the placebo/no LPS treatment in terms of live birth (OR 15.43, 95% CI 2.03 to 117.12, low evidence). Any active LPSs (except for rectal or subcutaneous progesterone) was significantly more efficacious than the placebo/no LPS treatment in terms of ongoing pregnancy, with ORs ranging between 1.77 (95% CI 1.08 to 2.90) for the vaginal progesterone pessary and 2.14 (1.23 to 3.70) for the intramuscular progesterone treatment. Among the comparisons of efficacy and tolerability between the active treatments, the differences were small and very uncertain.ConclusionDelays in progesterone supplementation until 96 h after oocyte retrieval does not affect pregnancy outcomes. The safety of GnRH agonists during the luteal phase needs to be evaluated in future studies before the applications of these agonists in clinical practice. With comparable efficacy and acceptability, there may be several viable clinical options for LPS.

Project description:Progesterone elevation (PE) during the late follicular phase of controlled ovarian stimulation in fresh embryo transfer in vitro fertilization (IVF)/intracytoplasmic sperm injection cycles has been claimed to be associated with decreased pregnancy rates. However, the evidence is not unequivocal, and clinicians still have questions about the clinical validity of measuring P levels during the follicular phase of stimulated cycles. We reviewed the existing literature aimed at answering four relevant clinical questions, namely (i) Is gonadotropin type associated with PE during the follicular phase of stimulated cycles? (ii) Is PE on the day of human chorionic gonadotropin (hCG) associated with negative fresh embryo transfer IVF/intracytoplasmic sperm injection (ICSI) cycles outcomes in all patient subgroups? (iii) Which P thresholds are best to identify patients at risk of implantation failure due to PE in a fresh embryo transfer? and (iv) Should a freeze all policy be adopted in all the cycles with PE on the day of hCG? The existing evidence indicates that late follicular phase progesterone rise in gonadotropin releasing analog cycles is mainly caused by the supraphysiological stimulation of granulosa cells with exogenous follicle-stimulating hormone. Yet, the type of gonadotropin used for stimulation seems to play no significant role on progesterone levels at the end of stimulation. Furthermore, PE is not a universal phenomenon with evidence indicating that its detrimental consequences on pregnancy outcomes do not affect all patient populations equally. Patients with high ovarian response to control ovarian stimulation are more prone to exhibit PE at the late follicular phase. However, in studies showing an overall detrimental effect of PE on pregnancy rates, the adverse effect of PE on endometrial receptivity seems to be offset, at least in part, by the availability of good quality embryo for transfer in women with a high ovarian response. Given the limitations of the currently available assays to measure progesterone at low ranges, caution should be applied to adopt specific cutoff values above which the effect of progesterone rise could be considered detrimental and to recommend "freeze-all" based solely on pre-defined cutoff points.
