Abstract STUDY QUESTION Will a delay in initiating IVF treatment affect pregnancy outcomes in infertile women with diminished ovarian reserve? SUMMARY ANSWER A delay in IVF treatment up to 180 days does not affect the live birth rate for women with diminished ovarian reserve when compared to women who initiate IVF treatment within 90 days of presentation. WHAT IS KNOWN ALREADY In clinical practice, treatment delays can occur due to medical, logistical or financial reasons. Over a period of years, a gradual decline in ovarian reserve occurs which can result in declining outcomes in response to IVF treatment over time. There is disagreement among reproductive endocrinologists about whether delaying IVF treatment for a few months can negatively affect patient outcomes. STUDY DESIGN, SIZE, DURATION A retrospective cohort study of infertile patients in an academic hospital setting with diminished ovarian reserve who started an IVF cycle within 180 days of their initial consultation and underwent an oocyte retrieval with planned fresh embryo transfer between 1 January 2012 and 31 December 2018. PARTICIPANTS/MATERIALS, SETTING, METHODS Diminished ovarian reserve was defined as an anti-Müllerian hormone (AMH) <1.1 ng/ml. In total, 1790 patients met inclusion criteria (1115 immediate and 675 delayed treatment). Each patient had one included cycle and no subsequent data from additional frozen embryo transfer cycles were included. Since all cycle outcomes evaluated were from fresh embryo transfers, no genetically tested embryos were included. Patients were grouped by whether their cycle started 1–90 days after presentation (immediate) or 91–180 days (delayed). The primary outcome was live birth (≥24 weeks of gestation). A subgroup analysis of more severe forms of diminished ovarian reserve was performed to evaluate outcomes for patients with an AMH <0.5 and for patients >40 years old with an AMH <1.1 ng/ml (Bologna criteria for diminished ovarian reserve). Logistic regression analysis, adjusted a priori for patient age, was used to estimate the odds ratio (OR) with a 95% CI. All pregnancy outcomes were additionally adjusted for the number of embryos transferred. MAIN RESULTS AND THE ROLE OF CHANCE The mean ± SD number of days from presentation to IVF start was 50.5 ± 21.9 (immediate) and 128.8 ± 25.9 (delayed). After embryo transfer, the live birth rate was similar between groups (immediate: 23.9%; delayed: 25.6%; OR 1.08, 95% CI 0.85–1.38). Additionally, a similar live birth rate was observed in a subgroup analysis of patients with an AMH <0.5 ng/ml (immediate: 18.8%; delayed: 19.1%; OR 0.99, 95% CI 0.65–1.51) and in patients >40 years old with an AMH <1.1 ng/ml (immediate: 12.3%; delayed: 14.7%; OR 1.21, 95% CI 0.77–1.91). LIMITATIONS, REASONS FOR CAUTION There is the potential for selection bias with regard to the patients who started their IVF cycle within 90 days compared to 91–180 days after initial consultation. In addition, we did not include patients who were seen for initial evaluation but did not progress to IVF treatment with oocyte retrieval; therefore, our results should only be applied to patients with diminished ovarian reserve who complete an IVF cycle. Finally, since we excluded patients who started their IVF cycle greater than 180 days from their first visit, it is not known how such a delay in treatment affects pregnancy outcomes in IVF cycles. WIDER IMPLICATIONS OF THE FINDINGS A delay in initiating IVF treatment in patients with diminished ovarian reserve up to 180 days from the initial visit does not affect pregnancy outcomes. This observation remains true for patients who are in the high-risk categories for poor response to ovarian stimulation. Providers and patients should be reassured that when a short-term treatment delay is deemed necessary for medical, logistic or financial reasons, treatment outcomes will not be affected. STUDY FUNDING/COMPETING INTEREST(S) No financial support, funding or services were obtained for this study. The authors do not report any potential conflicts of interest.

Abstract text In clinical practice, infertility treatment delays can occur due to medical, logistical, or financial reasons. Concerns over treatment delays were brought to the forefront in March 2020 when the SARS-CoV-2 pandemic prompted both the ESHRE and ASRM to recommend the suspension of new infertility treatment cycles. At the time, little was known about the risk of viral transmission on reproductive health and necessary medical resources urgently needed to be reallocated to the front lines of the pandemic. These society recommendations were met with resistance from some clinicians and patients that raised valid concerns about whether delaying IVF treatment for a few months could negatively affect pregnancy outcomes. To help answer this question, we designed a retrospective cohort study to assess whether a delay up to 180 days in initiating IVF treatment affects pregnancy outcomes in infertile women with diminished ovarian reserve. This population was selected because their treatment outcomes were the most likely to affected by treatment delays due to the continuous decline in ovarian reserve over time. Infertile women treated at our IVF center were included if they had diminished ovarian reserve and started an ovarian stimulation cycle within 180 days of their initial consultation that resulted in an oocyte retrieval with planned fresh embryo transfer between 1 January 2012 and 31 December 2018. Diminished ovarian reserve was defined as an anti-Mŭllerian hormone (AMH) < 1.1 ng/mL. In total, 1,790 patients met inclusion criteria (1,115 immediate and 675 delayed treatment). Each patient had one included cycle and no subsequent data from additional frozen embryo transfer cycles were included. Since all cycle outcomes evaluated were from fresh embryo transfers, no genetically tested embryos were included. Patients were grouped by whether their cycle started 1-90 days after presentation (immediate) or 91-180 days (delayed). The primary outcome was live birth (≥24 weeks of gestation). A subgroup analysis of more severe forms of diminished ovarian reserve was performed to evaluate outcomes for patients with an AMH < 0.5 and for patients >40 years old with an AMH < 1.1 ng/mL (Bologna criteria for diminished ovarian reserve). Logistic regression analysis, adjusted a priori for patient age, was used to estimate the odds ratio (OR) with a 95% CI. All pregnancy outcomes were additionally adjusted for the number of embryos transferred. The mean ± SD number of days from presentation to IVF start was 50.5 ± 21.9 (immediate) and 128.8 ± 25.9 (delayed). After embryo transfer, the live birth rate was similar between groups (immediate: 23.9%; delayed: 25.6%; OR 1.08, 95% CI 0.85-1.38). Additionally, a similar live birth rate was observed in a subgroup analysis of patients with an AMH < 0.5 ng/mL (immediate: 18.8%; delayed: 19.1%; OR 0.99, 95% CI 0.65-1.51) and in patients >40 years old with an AMH < 1.1 ng/mL (immediate: 12.3%; delayed: 14.7%; OR 1.21, 95% CI 0.77-1.91). Overall, we observed that a delay in initiating IVF treatment up to 180 days does not affect the live birth rate for women with diminished ovarian reserve when compared to women who initiate IVF treatment within 90 days of presentation. This observation persisted for patients who in the highest-risk categories for poor response to ovarian stimulation. Providers and patients should be reassured that when a short-term treatment delay is deemed necessary for medical, logistical, or financial reasons, treatment outcomes will not be negatively affected.

We examined whether treatment with minimum-dose stimulation (MS) protocol enhances clinical pregnancy rates compared to high-dose stimulation (HS) protocol. A retrospective cohort study was performed comparing IVF and pregnancy outcomes between MS and HS gonadotropin-antagonist protocol for patients with poor ovarian reserve (POR). Inclusion criteria included patients with an anti-Müllerian hormone (AMH) ≤8 pmol/L and/or antral follicle count (AFC) ≤5 on days 2-3 of the cycle. Patients from 2008 exclusively had a HS protocol treatment, while patients in 2010 had treatment with a MS protocol exclusively. The MS protocol involved letrozole at 2.5 mg over 5 days, starting from day 2, overlapping with gonadotropins, starting from the third day of letrozole at 150 units daily. GnRH antagonist was introduced once one or more follicles reached 14 mm or larger. The HS group received gonadotropins (≥300 IU/day) throughout their antagonist cycle. Clinical pregnancy rate was significantly higher in the MS protocol compared to the HS protocol (P=0.007). Furthermore, the live birth rate was significantly higher in the MS group compare to the HS group (P=0.034). In conclusion, the MS IVF protocol is less expensive (lower gonadotropin dosage) and resulted in a higher clinical pregnancy rate and live birth rate than a HS protocol for poor responders.

This retrospective study examines the influence of recombinant growth hormone (rGH) and dehydroepiandrosterone (DHEA) adjuvants on oocyte numbers, embryo utilization and live births arising from 3637 autologous IVF±ICSI treatment cycles undertaken on 2376 women across ten years (2011-2020) within a pioneer Australian facility. Despite using an FSH-dosing algorithm enabling maximal doses up to 450 IU for women with reduced ovarian reserve, younger women had significantly higher mean numbers of oocytes recovered than older women ranging from 11.1 for women <35 years to 9.4 for women aged 35-39 years reducing to 6.5 for women aged 40-44 years and 4.1 for those aged ≥45 years (p<0.0001). Overall, the embryo utilization rate was 48.5% and live birth productivity rate was 35.4 % across all ages and neither rGH nor DHEA showed any benefit on these rates, in fact, those women with nil adjuvants showed the highest live birth rate per initiated cycle (44.94% overall: p<0.0001, and 55.2% for the youngest group: p<0.001). Embryo utilization was increased by rGH in those women aged 40-44 years who had low ovarian reserve (p<0.0001), but this benefit did not translate into any improvement in the live birth rate, in fact those women who did not use adjuvants had the highest overall birth rate (p<0.0001). Similarly, other factors known to cause a poor prognosis, including low IGF-1 profile, recurrent implantation failure, and low oocyte numbers at OPU, showed no improvement in embryo utilization nor in live births from the adjuvants. The relevance of embryo quality was examined on 1135 women whose residual embryos after a single fresh-embryo transfer failed to develop to a suitable grade for cryopreservation. From 1727 cycles such women often displayed an improved embryo utilization rate with both rGH, and with DHEA or combined rGH+DHEA. Even so, live birth rates were not improved by either of the adjuvants excepting young women <35 years using rGH without DHEA (p<0.05). Examining poor prognosis sub-groups, indicated both rGH and DHEA or combined rGH+DHEA consistently improved embryo utilization in those women with low ovarian reserve (p<0.0001), or those with low IGF-1 levels (p<0.0001) or with recurrent implantation failure (p<0.02). All the poor-prognosis sub-groups showed low live birth rates and, notwithstanding the improvements in embryo utilization, the live birth rates were not significantly improved by the adjuvants, albeit the rates were closer to the nil adjuvant groups (not significantly different).

Abstract BackgroundAbnormal reproductive tract flora may cause infertility, and it may play a key role in the success of assisted reproductive technologies (ART). The obvious short-term changes in estrogen caused by clinical protocols with IVF-ET provide a unique perspective for us to assess the vaginal flora, shifting hormonal condition and investigate the potential associations of the vaginal micro-ecology with cycle outcome of pregnancy. The Vaginal Micro-ecology Evaluation System (VMES) as a tool to analyze the vaginal microbiomes in most areas of China. This study aims to apply the VMES to evaluate the dynamics of vaginal micro-ecology during IVF-ET, and investigate the correlations between vaginal micro-ecology with pregnancy outcome.Methods　150 patients were enrolled who underwent early follicular phase prolonged protocol IVF-ET due to tubal factors. The VMES is used to evaluate vaginal microbiology indicators of vaginal swabs obtained in different hormonal milieu during the IVF-ET cycle. The pregnancy outcomes were observed, if pregnant.Results　In our data, the prevalence of bacterial vaginitis (BV) accounts for 3.3%. During IVF procedure, the vaginal microbiome varied across hormonal milieu in some but not all patients. The proportion of BV, and unidentified dysbiosis were increased significantly on the day of human chorionic gonadotropin (HCG) administration. The vaginal micro-ecology on the day of HCG administration correlated with outcome (live birth / no live birth). The multivariable logistic regression model showed that the average age, the duration of infertility, and the vaginal micro-ecology after controlled ovarian hyperstimulation (COH) were associated with the live birth rate.ConclusionOur retrospective cohort study suggests that the VEMS has enabled discovery of unidentified dysbiosis shift in the vaginal micro-ecology during IVF-ET therapy. More importantly, the vaginal micro-ecology on the day of HCG administration was significantly associated with the live birth rate.
