Abstract
Importance The safety of exogenous gonadotropin treatment, based on its effect on embryos and pregnancy outcomes, remains inconclusive. Objective To evaluate the associations of different doses and durations of gonadotropins with embryonic genetic status and pregnancy outcomes after euploid embryo transfer in couples with infertility. Design, Setting, and Participants This study was a post hoc analysis of a multicenter randomized clinical trial (RCT) conducted at 14 reproductive centers throughout China from July 2017 to June 2018 that evaluated the cumulative live birth rate with or without preimplantation genetic testing for aneuploidy (PGT-A) among couples with infertility and good prognosis. The PGT-A group from the original RCT was selected for secondary analysis. Patients were divided into 4 groups according to the total dosage of exogenous gonadotropins and treatment duration: group 1 (≤1500 IU and <10 days), group 2 (≤1500 IU and ≥10 days), group 3 (>1500 IU and <10 days), and group 4 (>1 500 IU and ≥10 days). Group 1 served as the control group. Data were analyzed from June through August 2023. Interventions Blastocyst biopsy and PGT-A. Main outcomes and measures The primary outcomes were embryonic aneuploidy, embryonic mosaicism, and cumulative live birth rates after euploid embryo transfer. Results A total of 603 couples (mean [SD] age of prospective mothers, 29.13 [3.61] years) who underwent PGT-A were included, and 1809 embryos were screened using next-generation sequencing. The embryo mosaicism rate was significantly higher in groups 2 (44 of 339 embryos [13.0%]; adjusted odds ratio [aOR], 1.69 [95% CI, 1.09-2.64]), 3 (27 of 186 embryos [14.5%]; aOR, 1.98 [95% CI, 1.15-3.40]), and 4 (82 of 651 embryos [12.6%]; aOR, 1.60 [95% CI, 1.07-2.38]) than in group 1 (56 of 633 embryos [8.8%]). There were no associations between gonadotropin dosage or duration and the embryo aneuploidy rate. The cumulative live birth rate was significantly lower in groups 2 (83 of 113 couples [73.5%]; aOR, 0.49 [95% CI, 0.27-0.88]), 3 (42 of 62 couples [67.7%]; aOR, 0.41 [95% CI, 0.21-0.82]), and 4 (161 of 217 couples [74.2%]; aOR, 0.53 [95% CI, 0.31-0.89]) than in group 1 (180 of 211 couples [85.3%]). Conclusions and relevance In this study, excessive exogenous gonadotropin administration was associated with increased embryonic mosaicism and decreased cumulative live birth rate after euploid embryo transfer in couples with a good prognosis. These findings suggest that consideration should be given to minimizing exogenous gonadotropin dosage and limiting treatment duration to improve embryo outcomes and increase the live birth rate.

A hybrid artificial intelligence model leverages multi-centric clinical data to improve fetal heart rate pregnancy prediction across time-lapse systems. Hum Reprod 2023; 38:596-608. [PMID: 36763673 PMCID: PMC10068266 DOI: 10.1093/humrep/dead023] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2022] [Revised: 01/10/2023] [Indexed: 02/12/2023] Open
Abstract
STUDY QUESTION Can artificial intelligence (AI) algorithms developed to assist embryologists in evaluating embryo morphokinetics be enriched with multi-centric clinical data to better predict clinical pregnancy outcome? SUMMARY ANSWER Training algorithms on multi-centric clinical data significantly increased AUC compared to algorithms that only analyzed the time-lapse system (TLS) videos. WHAT IS KNOWN ALREADY Several AI-based algorithms have been developed to predict pregnancy, most of them based only on analysis of the time-lapse recording of embryo development. It remains unclear, however, whether considering numerous clinical features can improve the predictive performances of time-lapse based embryo evaluation. STUDY DESIGN, SIZE, DURATION A dataset of 9986 embryos (95.60% known clinical pregnancy outcome, 32.47% frozen transfers) from 5226 patients from 14 European fertility centers (in two countries) recorded with three different TLS was used to train and validate the algorithms. A total of 31 clinical factors were collected. A separate test set (447 videos) was used to compare performances between embryologists and the algorithm. PARTICIPANTS/MATERIALS, SETTING, METHODS Clinical pregnancy (defined as a pregnancy leading to a fetal heartbeat) outcome was first predicted using a 3D convolutional neural network that analyzed videos of the embryonic development up to 2 or 3 days of development (33% of the database) or up to 5 or 6 days of development (67% of the database). The output video score was then fed as input alongside clinical features to a gradient boosting algorithm that generated a second score corresponding to the hybrid model. AUC was computed across 7-fold of the validation dataset for both models. These predictions were compared to those of 13 senior embryologists made on the test dataset. MAIN RESULTS AND THE ROLE OF CHANCE The average AUC of the hybrid model across all 7-fold was significantly higher than that of the video model (0.727 versus 0.684, respectively, P = 0.015; Wilcoxon test). A SHapley Additive exPlanations (SHAP) analysis of the hybrid model showed that the six first most important features to predict pregnancy were morphokinetics of the embryo (video score), oocyte age, total gonadotrophin dose intake, number of embryos generated, number of oocytes retrieved, and endometrium thickness. The hybrid model was shown to be superior to embryologists with respect to different metrics, including the balanced accuracy (P ≤ 0.003; Wilcoxon test). The likelihood of pregnancy was linearly linked to the hybrid score, with increasing odds ratio (maximum P-value = 0.001), demonstrating the ranking capacity of the model. Training individual hybrid models did not improve predictive performance. A clinic hold-out experiment was conducted and resulted in AUCs ranging between 0.63 and 0.73. Performance of the hybrid model did not vary between TLS or between subgroups of embryos transferred at different days of embryonic development. The hybrid model did fare better for patients older than 35 years (P < 0.001; Mann-Whitney test), and for fresh transfers (P < 0.001; Mann-Whitney test). LIMITATIONS, REASONS FOR CAUTION Participant centers were located in two countries, thus limiting the generalization of our conclusion to wider subpopulations of patients. Not all clinical features were available for all embryos, thus limiting the performances of the hybrid model in some instances. WIDER IMPLICATIONS OF THE FINDINGS Our study suggests that considering clinical data improves pregnancy predictive performances and that there is no need to retrain algorithms at the clinic level unless they follow strikingly different practices. This study characterizes a versatile AI algorithm with similar performance on different time-lapse microscopes and on embryos transferred at different development stages. It can also help with patients of different ages and protocols used but with varying performances, presumably because the task of predicting fetal heartbeat becomes more or less hard depending on the clinical context. This AI model can be made widely available and can help embryologists in a wide range of clinical scenarios to standardize their practices.

Reprod Biol Endocrinol 2022; 20:171. [PMID: 36536380 PMCID: PMC9762009 DOI: 10.1186/s12958-022-01049-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/03/2022] [Accepted: 12/13/2022] [Indexed: 12/23/2022] Open
Abstract
OBJECTIVE Nowadays, patients attempting social/elective egg freezing has spread globally. Ovarian stimulation (OS) with high daily gonatotropin doses, are commonly offered to this group of patients, aiming to achieve the maximal oocytes cohort with minimum IVF cycle attempts. We aim to assess the IVF-ET outcome, and specifically the oocyte yield, of patients undergoing two successive IVF cycle attempts for elective egg freezing (EEF), and whether changing the daily gonadotropin dose in the second IVF cycle attempt, affect the outcome. PATIENTS AND METHODS All women admitted to our IVF unit for social/EEF, who underwent 2 consecutive IVF cycle attempts, with only those who used in the first attempt a starting daily gonadotropin dose of 300 IU were included. Ovarian stimulation characteristics, duration of OS, number of retrieved oocytes, number of mature oocytes were assessed and compared between the 1st and the 2nd IVF cycle attempts, and between the different daily gonadotropin doses and the oocyte yields in the 2nd cycle attempt (increase, decrease or no change). MAIN OUTCOME MEASURES Oocytes and mature oocytes yield in the 2nd as compared to the 1st IVF cycle attempt. RESULTS A reduced oocyte yield in the 2nd cycle attempt was observed in those who highly responded in the 1st attempt, regardless the daily dose in the 2nd cycle attempt (whether it was increased, no change and decreased). Moreover, the proportion of patients with same or more oocytes in the 2nd IVF cycle attempt was significantly lower in patients with high peak E2 levels, compared to those with peak E2 levels < 9175 pmol/L. Among patients with high peak E2 (> 9175 pmol/L), those who achieved a lower oocytes yield in the 2nd IVF cycle attempt had lower basal Day-3 FSH/LH ratio (1.5 + 0.5 vs 1.8 + 0.8, p < 0.03) and higher oocyte (range: 7-28, median:10; vs range: 2-15, median:7) and mature oocytes yields. With a cut-off of 9 oocytes, 78.8% of those with > 9 oocytes and 61.8% of those with < 9 oocytes will achieve lower/higher oocytes yield in the 2nd IVF cycle attempt, respectively. CONCLUSIONS Ovarian stimulation with high daily gonatotropin doses (300 IU) should be offered to patients attempting social/EEF. Moreover, in their 2nd IVF cycle attempt, those with high peak E2 (> 9175 pmol/L) in the 1st attempt, and basal Day-3 FSH/LH ratio < 1.5 and/or more than 9 oocytes retrieved, should receive same OS protocol with no change in the daily gonadotropin dose.

Buratini J, Dellaqua TT, Dal Canto M, La Marca A, Carone D, Mignini Renzini M, Webb R. The putative roles of FSH and AMH in the regulation of oocyte developmental competence: from fertility prognosis to mechanisms underlying age-related subfertility. Hum Reprod Update 2021; 28:232-254. [PMID: 34969065 DOI: 10.1093/humupd/dmab044] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2021] [Revised: 11/18/2021] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND Fertility loss during female ageing is associated with increasing basal FSH and decreasing anti-Müllerian hormone (AMH) concentrations, together with compromised oocyte quality, presumably due to increased oxidative stress (OS) and DNA damage, as well as reduced metabolic and meiotic competences. Basal FSH and AMH circulatory concentrations have been broadly utilized as IVF success predictors, regardless of fluctuations in prognostic accuracy; basal FSH and AMH perform better in pre-advanced maternal age (AMA: >35 years) and AMA patients, respectively. The relationships between FSH and AMH intrafollicular levels and IVF outcomes suggest, nevertheless, that both hormones regulate oocyte competence, supporting the hypothesis that changes in FSH/AMH levels cause, at least in part, oocyte quality degradation during ageing. To understand the reasons behind the fluctuations in FSH and AMH prognostic accuracies and to clarify their participation in mechanisms determining oocyte competence and age-related subfertility, a deeper knowledge of the regulation of FSH and AMH intrafollicular signalling during the female reproductive lifespan, and of their effects on the cumulus-oocyte complex, is required. OBJECTIVE AND RATIONALE An extensive body of information on the regulation of FSH and AMH intrafollicular availability and signalling, as well as on the control of folliculogenesis and oocyte metabolism, has been accumulated. However, these datasets have been explored within the relatively narrow boundaries of their specific subjects. Given the aforementioned gaps in knowledge and their clinical relevance, herein we integrate clinical and basic data, within a wide biological perspective, aiming to shed light on (i) the reasons for the variability in the accuracy of serum FSH and AMH as fertility markers, and on (ii) the potential roles of these hormones in mechanisms regulating oocyte quality, particularly those associated with ageing. SEARCH METHODS The PubMed database encompassing the period between 1960 and 2021 was searched. Principal search terms were FSH, FSH receptor, AMH, oocyte, maternal age, cumulus, transzonal projections (TZPs), actin, OS, redox, reactive oxygen species, mitochondria, DNA damage, DNA repair, aneuploidy, spindle, meiosis, gene expression, transcription, translation, oocyte secreted factors (OSFs), cAMP, cyclic guanosine monophosphate, natriuretic peptide C, growth differentiation factor 9, bone morphogenetic protein 15 and fibroblast growth factor. OUTCOMES Our analysis suggests that variations in the accuracy of fertility prognosis reflect a modest association between circulatory AMH levels and oocyte quality as well as increasing basal FSH inter-cycle variability with age. In addition, the basic and clinical data articulated herein support the hypothesis that increased intrafollicular FSH levels, as maternal age advances, may override the physiological protective influences of AMH and OSFs against excessive FSH signalling in cumulus cells. This would result in the disruption of oocyte homeostasis via reduced TZP-mediated transfer of cumulus-derived molecules essential for meiotic competence, gene expression, redox activity and DNA repair. WIDER IMPLICATIONS In-depth data analysis, encompassing a wide biological perspective has revealed potential causative mechanisms of age-related subfertility triggered by alterations in FSH/AMH signalling during the female reproductive life. Insights from new mechanistic models arising from this analysis should contribute to advancing our comprehension of oocyte biology in humans and serve as a valuable reference for novel AMA subfertility treatments aimed at improving oocyte quality through the modulation of AMH/FSH action.

Clark ZL, Thakur M, Leach RE, Ireland JJ. FSH dose is negatively correlated with number of oocytes retrieved: analysis of a data set with ~650,000 ART cycles that previously identified an inverse relationship between FSH dose and live birth rate. J Assist Reprod Genet 2021; 38:1787-1797. [PMID: 33834326 DOI: 10.1007/s10815-021-02179-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2021] [Accepted: 03/28/2021] [Indexed: 12/17/2022] Open
Abstract
PURPOSE To evaluate whether total FSH dose was negatively correlated with number of oocytes retrieved in a large data set where previously, a negative correlation between FSH dose and live birth rate was identified. METHODS Data from 650,637 fresh autologous in vitro fertilization (IVF) cycles reported to the Society for Assisted Reproductive Technology between 2004 and 2012 were included. Logistic regression analysis was performed to determine if the relationship between total FSH dose used during ART with number of oocytes retrieved was impacted by the patient's health prognosis, age, BMI, ovarian stimulation protocol, or infertility diagnosis. RESULTS The number of oocytes retrieved was negatively correlated with FSH dose (P < 0.0001). Regardless of patient prognosis, age, BMI, ovarian stimulation protocol, and infertility diagnosis, the highest number of oocytes retrieved was in the 1001-2000 IU FSH group, and was 36-51% lower in the > 5000 IU compared with the optimal, 1001-2000 IU, FSH groups. Overall, ~80% of patients received FSH doses outside of the optimal FSH dose. Moreover, 61% of good prognosis patients (excludes individuals likely prescribed higher FSH doses) received doses exceeding the optimal dose range. CONCLUSION The inverse relationship between FSH dose and the number of oocytes retrieved independent of patient age or health implies that excessive FSH doses during ART may be detrimental to oocyte retrieval.

Abstract
RESEARCH QUESTION Does the addition of human growth hormone (HGH) to an IVF cycle improve the live birth rate in previously documented poor responders to FSH? DESIGN Double-blind, placebo-controlled, randomized clinical trial comparing HGH to placebo in maximal stimulation in an IVF cycle. The study was stopped after 4 years. Women receiving ovarian stimulation in one IVF cycle, having failed to produce more than 5 eggs in a previous cycle with more than 250 IU/day of FSH were included. Basal FSH was ≤15 IU/l, body mass index <33 kg/m2, age <41 years. HGH or placebo were added from the start of the cycle in a double-blinded manner. The primary outcome was live birth rate. MAIN RESULTS The live birth rates following an IVF cycle were 9/62 (14.5%) for growth hormone and 7/51 (13.7%) for the placebo group (risk difference 0.8%, 95% confidence interval [CI] -12.1 to 13.7%; odds ratio [OR] 1.07, 95% CI 0.37-3.10). There was a greater odds of oocyte retrieval with growth hormone (OR 5.67, 95% CI 1.54-20.80) but no better chance of embryo transfer (OR 1.42, 95% CI 0.50-4.00). Birth weights were comparable. CONCLUSIONS Planned participant numbers were not reached. It was not possible to demonstrate an increase in live birth rate from the addition of growth hormone in women with a previous poor ovarian response to IVF.

Abstract
Objective To determine the effect of FSH doses on intracytoplasmic sperm injection
(ICSI) outcomes according to the age of the patient. Methods Patients undergoing controlled ovarian stimulation (COS) for ICSI cycles in a
university-affiliated in vitro fertilization center were
split into age groups: ≤35 y.o. (n=1523); >35 and ≤38 y.o.
(n=652); >38 and ≤40 y.o. (n=332); and >40 y.o. (n=370). The
effect of FSH dose on COS, laboratorial and clinical outomes was determined
by linear regression models. Results The FSH dose didn't affect the ovarian response in terms of total number of
follicles, retrieved oocytes and mature oocytes within the age groups, but
we found that the lower the age, the lower the FSH dose needed per oocyte
retrieved. In the group of patients ≤35 y.o., we also found a
positive effect of the FSH dose on oocyte yield. Despite that, for patients
≤38 y.o. there was a negative effect of the FSH dose on embryo
quality and blastocyst formation rate, and an increase in the cycle's
cancelation rate. In patients ≥39 y.o., there were no effects of the
FSH doses on the analysed variables. Conclusions Ovarian stimulation with high doses of FSH is not recommended in younger
women (≤38 y.o.), once we found a decrease in embryo quality and an
increase in cycle's cancelation rate. Mild ovarian stimulation protocols may
be more appropriate; however, it may not be applicable for women in advanced
age, since a higher FSH dose is needed for oocyte retrieval in these
patients.

Abstract
AIM As no upper limit of the daily dose of gonadotropins (DD GN) used for controlled ovarian hyperstimulation (COH) in patients undergoing assisted reproductive technology (ART) has been established, we aimed to evaluate the efficacy of using different DD GN in terms of live-birth achievement. METHODS Data of patients treated at a single university medical center during the same period was analyzed retrospectively. Four groups were analyzed according to the DD GN administered: group I ("high dose"): >225- ≤ 375 IU; Group II ("Very high dose"): 376-450 IU; group III ("extremely high dose"): 451-600 IU. Normo-responders treated with DD GN ≤250 IU served as control (C). Variables included were DD GN, total GN dose/cycle, age, FSH, BMI, gravidity, parity, cycle number, IVF/ICSI, infertility diagnosis treatment protocol and outcome parameters. RESULTS The analysis of 1394 treatment cycles of 943 patients indicated that DD and total dose of GN correlated negatively with the number of oocytes, implantation, clinical pregnancy and live-birth rate (25.9%, 14.6%, 11.4% and 4.7% in groups C, I, II and III, respectively) The logistic regression analysis indicated that the adjusted odds ratios for LBR correlated inversely with the DD administered - independently from age, baseline FSH, BMI and previous failed cycles. CONCLUSIONS Increasing the daily dose of GN to doses higher than 450 IU or a total dose of 3000 IU/cycle is at least questionable if not harmful.

Abstract
OBJECTIVE To evaluate the correlation between total gonadotropin dose and live birth rate. DESIGN Retrospective analysis. SETTING Not applicable. PATIENT(S) A total of 658,519 fresh autologous cycles of in vitro fertilization (IVF) reported to the Society for Assisted Reproductive Technology from 2004 to 2012. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Logistic regression models were fitted to live birth rates with the use of categorized values for total FSH dose and number of oocytes retrieved as the primary predictor variables. To reduce the effect of the most significant confounders that may lead physicians to prescribe higher doses of FSH, additional analyses were performed limited to good-prognosis patients (<35 years of age, body mass index <30 kg/m(2), and no diagnosis of diminished ovarian reserve, endometriosis, or ovulatory disorder) and including duration of gonadotropin treatment. RESULT(S) Live birth rate significantly decreased with increasing FSH dose, regardless of the number of oocytes retrieved. The statistically significant decrease in live birth rate with increasing FSH dose remained in patients with good prognosis, and regardless of female age, except for women aged ≥ 35 years with 1-5 oocytes retrieved. CONCLUSION(S) This analysis suggests that physicians may wish to avoid prescribing a high dose of FSH. However, the results of this study do not justify the use of minimal-stimulation or natural-cycle IVF.

Abstract
We aim to assess the in vitro fertilization-embryo transfer (IVF-ET) outcome in patients receiving an extremely high 450 daily dose (IU) of gonadotropins during controlled ovarian hyperstimulation (COH) for IVF. Moreover, in those who failed to conceive while using 450 daily dose (IU) of gonadotropins, we aim to evaluate whether increasing the daily dose gonadotropins to 600 IU will improve IVF outcome. All consecutive women, admitted to our IVF unit and underwent COH consisting of daily gonadotropin dose of 450 IU were included. Ovarian stimulation characteristics, number of oocytes retrieved, number of embryo transferred and pregnancy rate were assessed. Nine-hundred one consecutive IVF cycles were evaluated. While there was no between-group difference in the duration of COH, patients who conceived were significantly younger, yielded higher number of oocytes retrieved and embryos transferred and had significantly lower cancellations. In a sub-analysis, including only those patients who failed to conceive while using 450 daily dose (IU) of gonadotropins, and who underwent a subsequent IVF cycle attempt with the used of 600 IU daily dose of gonadotropins, no improvements in COH characteristics or cancellation rates were observed with increasing the daily gonadotropin dose to 600 IU. To conclude, in poor responders undergoing COH with an extremely high daily gonadotropin dose (450 IU), the most important factors that predict IVF success are female age and the number of oocytes retrieved. Moreover, patients who failed to conceive on a daily gonadotropin dose of 450 IU will not benefit from increasing the dose to 600 IU and should therefore consider the options of egg donation or adoption.

Abstract
The use of dehydroepiandrosterone (DHEA) supplementation in infertile patients with diminished ovarian reserve (DOR) has become increasingly popular. It has been our observation that serum progesterone levels during the follicular phase are often increased during controlled ovarian stimulation when DHEA is coadministered. Our aim was to compare progesterone levels during the follicular phase before and during DHEA supplementation in women with DOR undergoing in vitro fertilization (IVF). In a case-control study, we compared progesterone levels during the follicular phase in IVF cycles before and during DHEA supplementation in 15 women with DOR who received 75 mg of DHEA daily. Progesterone levels on stimulation day 5 (0.5 ± 0.29 ng/ml vs. 1.54 ± 0.49 ng/ml; p < 0.0001) and on the day of human chorionic gonadotropin administration (0.75 ± 0.31 ng/ml vs. 1.87 ± 0.49 ng/ml; p < 0.0001) were significantly higher during DHEA treatment. The number of retrieved and fertilized oocytes was similar in both the groups. DHEA administration during IVF cycles in women with DOR causes a significant elevation of progesterone levels without an apparent deleterious effect on cycle outcome.

Abstract
PURPOSE To test the hypothesis that aged women with poor ovarian response express an increase on embryo chromosomal alterations when compared to aged women who presented normal response. METHODS Couples undergoing intracytoplasmic sperm injection cycles with preimplantation genetic screening, were subdivided into two groups: Poor Responder group (n = 34), patients who produced ≤4 oocytes; and Normoresponder group (n = 50), patients who produced ≥5 oocytes. Groups were compared regarding cycles' outcomes and aneuploidy frequency. RESULTS There were no significant differences between and groups regarding the fertilization rate (p = 0.6861), clinical pregnancy (p = 0.9208), implantation (p = 0.6863), miscarriage (p = 0.6788) and the percentage of aneuploid embryos (p = 0.270). Embryo transfer rate was significantly lower on poor responder group (p = 0.0128) and logistic regression confirmed the influence of poor response on the chance of embryo transfer (p = 0.016). CONCLUSIONS Aged females responding poorly to gonadotrophins are not at a higher risk for producing aneuploid embryos in vitro.

Abstract
PURPOSE To test the possibility of stimulating ovaries with a mild IVF approach using a GnRH agonist long protocol. METHODS Retrospective study of 142 first IVF cycles of women aged 30 to 35 who had undergone stimulation with 100 IU or 150 IU of rFSH. RESULTS The mean dose of rFSH used was smaller in the low dose compared with the high dose group (999 vs. 1343 IU; p<0.001), obtaining comparable numbers of mature oocytes in both groups. Additionally, reducing the mean number of embryos transferred from 1.8 to 1.5 significantly decreased the twin rate in the low dose group while maintaining similar pregnancy rates in both groups. CONCLUSIONS It is possible to develop mild IVF using GnRH agonist long protocol in women with good prognosis. A reduced amount of rFSH and fewer transferred embryos allow for lower costs and risks of IVF without compromising the pregnancy rate.

Abstract
OBJECTIVE To develop a prognostic model for the prediction of ongoing pregnancy after single-embryo transfer (SET) following mild stimulation for IVF in women less than 38 years of age. DESIGN Prospective cohort study. SETTING Two fertility centers in tertiary referral university hospitals. PATIENT(S) A total of 152 women with an elective SET following mild ovarian stimulation (cycle day 5 start of 150 IU/day recombinant FSH and late follicular phase GnRH antagonist cotreatment). INTERVENTION(S) Database analysis. MAIN OUTCOME MEASURE(S) Ongoing pregnancy. RESULT(S) The ongoing pregnancy rate per elective SET was 28% (42 of 152). In a multivariate logistic regression analysis, body mass index, the total gonadotrophin dose needed, and number of oocytes retrieved were negatively correlated whereas the availability of a top-quality embryo was positively correlated with ongoing pregnancy. The predictive ability of the model assessed by the area under the receiver operating characteristic curve was 0.68. At a probability cut-off level of 0.20 the model showed a sensitivity of 37% and a specificity of 90%. CONCLUSION(S) The developed prediction model for ongoing pregnancy provides an evidence-based strategy for guidance under which conditions SET may be performed. After external validation, application of the model may help to improve overall singleton pregnancy rates.

The rate at which serum total beta-subunit human chorionic gonadotropin increases after embryo transfer is a predictor of the viability of pregnancy and an identifier of determinants of pregnancy. Fertil Steril 2006; 86:1626-33.

Abstract
OBJECTIVE To determine whether elements of treatment associated with faster doubling times of total beta-hCG in serum (beta-t2) in pregnant patients are also associated with a higher likelihood of pregnancy in all patients. DESIGN Retrospective analysis of beta-t2 values, elements of ovarian stimulation (COH), and outcomes. SETTING Private assisted reproductive technology (ART) center. PATIENT(S) Initial analysis of data from 432 cycles in which conception occurred after COH and embryo transfer, followed by analysis of pregnancy outcomes after 1,287 cycles of COH/ embryo transfer. INTERVENTION(S) No interventions. MAIN OUTCOME MEASURES The beta-t2 values initially computed from consecutive serum beta-hCG levels in ongoing pregnancies were correlated with multiple properties of the patients and their treatment cycles. RESULT(S) The beta-t2 values during early pregnancy increased exponentially from about 1.6 days at 12 days to about 3.0 days at 24 days after embryo transfer. In those pregnancies which spontaneously aborted, early average beta-t2 values were higher than those for ongoing pregnancies; absolute beta-hCG levels did not differ. Positive correlations were established between beta-t2 values, the number of days of stimulation, and the number of ampules of drug administered per oocyte retrieved. The beta-t2 values were inversely related to average numbers of blastomeres in transferred embryos. Ongoing pregnancy rates (PR) were higher for cycles with lower gonadotropin dosages per oocyte retrieved, and when the average number of blastomeres in transferred embryos was higher. CONCLUSION(S) Steeper beta-hCG doubling times in early pregnancy were associated with lower gonadotropin dosages during ovarian stimulation and with higher numbers of blastomeres in transferred embryos. The latter variables were, in turn, associated with a higher likelihood of pregnancy after embryo transfer.

Abstract
Choosing the number of embryos to be transferred is a major problem in assisted reproductive technologies. This study aimed to establish and validate a score predicting implantation rates in order to help in the choice of the number of embryos to be transferred, allowing the best compromise between high pregnancy rate and low multiple pregnancy risk. Clinical and biological parameters influencing implantation rates were retrospectively analysed in 739 embryo transfers and an implantation score was established. This score was then prospectively validated in 521 embryo transfers. Three parameters (age, ovarian response to FSH stimulation and embryo morphology) appeared to be predictive of the implantation rates and were included in an implantation score (3-9). The prospective study confirmed the validity of the score since implantation rates were higher when the score increased (5.9% for score 3 versus 22.4% for score 9; P < 0.05). Therefore, success rates can be predicted by the implantation score, which is of clinical value in choosing the number of embryos to be transferred in order to decrease multiple pregnancies while keeping high pregnancy rates. However, choosing the right number of embryos to be transferred needs further studies, since the percentage of multiple pregnancies remained relatively high in this prospective study (27%).

Abstract
The widely applied practice of a gonadotrophin dose increase in case of low response is not on an evidence-based level and not efficacious. All known comparative studies failed to show a difference in favour of the high-dose group regarding their pregnancy rate per embryo transfer. However if more oocytes and more embryos are available for cryopreservation, the real benefit in terms of cumulative pregnancy outcome might be with the high-dose regimen. This publication will show - as a review of the literature - that the frequent clinical practice of increasing the FSH dose does not lead to a higher pregnancy rate, which is in line with recommendation for milder stimulation regimes in IVF. Thus, the collective evidence to date would suggest that 150 IU/day to 250 IU/day of FSH or human menopausal gonadotrophin (HMG) is an appropriate starting dose for most women undergoing ovarian hyperstimulation for IVF as part of a gonadotrophin-releasing hormone (GnRH) antagonist or a long GnRH agonist protocol.

Abstract
To review treatment options for poor-responding patients who are undergoing infertility treatment. Review article and case studies.A comprehensive determination of potential ovarian response for the poor-responding patient is important in the individualization of treatment options for these patients. Treatment options include both the microdose flare leuprolide acetate and GnRH antagonist stimulation protocols. For GnRH antagonist stimulation protocols, individualization of treatment includes use of oral contraceptive pretreatment and alterations in duration of gonadotropin stimulation and start day of antagonist administration. For poor-responding patients, the benefits of using GnRH antagonists for the suppression of premature LH surges plus the determination that stimulation protocols that include GnRH antagonists are at least as good as the microdose flare and provide better cycle outcomes than the long luteal leuprolide acetate down-regulation protocols have the potential to bring changes to the existing protocols for ovarian stimulation.

Abstract
PURPOSE To determine the efficiency of transferring human zygotes as opposed to human day 2 or 3 embryos. METHODS A prospective, randomized, Multicenter trial. Patients were randomized into zygote or embryo transfer. Patients were prepared for oocyte retrieval using standardized protocols. Oocyte retrieval was performed under general anesthesia. Oocytes and spermatozoa were treated using standard laboratory techniques. All protocols were coordinated by the coordinating center. RESULTS A total of 386 patients were included in the trial. Pregnancy rates were 36.5% after zygote transfer and 42% after embryo transfer. Implantation rates were equivalent (17%) in both groups. CONCLUSIONS No general difference was observed for zygote or embryo transfer. The results suggest that zygote transfer is a valid alternative to embryo transfer.

Abstract
OBJECTIVE To evaluate the value of increasing the gonadotrophin dose after 5 days of controlled ovarian stimulation in IVF patients who show an initial poor response to stimulation. SUBJECTS AND METHODS We identified all IVF cycles between January 1992 and March 1996 in which ovarian response after 5 days of controlled ovarian hyperstimulation (COH) with 225-300 IU per day of human menopausal gonadotrophins (hMG; Metrodin or Pergonal) was monitored by measurement of serum estradiol concentrations (n=596 patients). According to estradiol concentration, the daily dose of hMG was doubled or increased to 450 IU in 193 patients (group A) or maintained the same in 403 patients (group B). Further cycle monitoring was achieved using serial ultrasound and serum estradiol measurements. RESULTS The two groups were age-matched. Group A patients experienced a higher cancellation rate despite having a higher mean number of hMG ampoules (59.5 versus 36.2) and a longer duration of stimulation (12.2 versus 10.8 days). They achieved lower levels of serum estradiol on days 9 and 10 of stimulation, produced a lower mean number of oocytes per retrieval (5.8 versus 8.9) and had a lower clinical pregnancy rate per cycle (8.3 versus 23.4%) compared to group B. All differences were statistically significant. CONCLUSION The poor outcome of cycles with initial low response to COH appears not to be averted by doubling or increasing the hMG dose after 5 days of stimulation.

Abstract
PURPOSE To investigate the various methods of evaluation and treatment of patients with a low response to controlled ovarian hyperstimulation in assisted reproductive technologies (ART). METHODS Review and analysis of relevant studies published in the last decade, identified through the literature and Medline searches. RESULTS While a universally accepted definition for low responders is still lacking, these patients are reported to represent about 10% of the ART population. Several ovarian reserve screening techniques have been proposed; however, currently the best-characterized and most sensitive screening tools available are the basal day 3 serum follicle-stimulating hormone level and the clomiphene citrate challenge test. When abnormal, these tests allow physicians to counsel patients that their prognosis for conception is poor. Although the presence of a normal result does indicate better long-term chances for conception, on age-related decline in fecundity remains and patient age should still be considered when counseling patients with normal screening results. Several stimulation protocols have been applied in the low-response group with varying success. Recent studies show that the use of a minidose gonadotropin-releasing hormone-agonist protocol may result in significantly decreased cycle cancellations as well as increased clinical and ongoing pregnancies, and thus is proposed as a first-line therapy. Studies evaluating supplementary forms of treatment to the ovulation induction regimen show improved outcome when pretreating with oral contraceptives, whereas there seems to be no benefit from cotreatment with growth hormone or glucocorticoids. Blastocyst culture and transfer and assisted hatching in low responders are still under evaluation, whereas natural cycle in vitro fertilization may be used in cases of repeated failures as a last option before resorting to oocyte donation or adoption. Future possible forms of treatment like in vitro maturation of immature human oocytes, cytoplasm, and nuclear transfer currently are experimental in nature and their efficacy has still to be proven. CONCLUSIONS The evaluation and treatment of low responders in ART remains a challenge. Understanding of the underlying etiology and pathophysiology of this disorder may help the clinician to approach it successfully.

Abstract
OBJECTIVE To evaluate whether ovarian stromal blood flow velocity after pituitary suppression is predictive of ovarian response and the outcome of IVF treatment in patients with normal basal serum FSH levels and to compare the predictive value of this test with age, early follicular phase serum FSH level, E2 level, and FSH:LH ratio. DESIGN Prospective observational study of women undergoing IVF treatment. SETTING A tertiary referral center for assisted reproduction. PATIENT(S) Eighty-eight women who received the long buserelin acetate treatment protocol. INTERVENTION(S) Transvaginal color and pulsed Doppler measurement of the ovarian stromal peak systolic velocity (PSV) after pituitary suppression and measurement of the basal serum FSH level, E2 level, and FSH:LH ratio. MAIN OUTCOME MEASURE(S) Number of mature oocytes retrieved and pregnancy rate. RESULT(S) Ovarian stromal PSV was the most important single independent predictor of ovarian response in patients with a normal basal serum FSH level, when compared with age, basal FSH level, E2 level, or FSH:LH ratio. Patients in group 2 (PSV > or = 10 cm/s) had a significantly higher median number of mature oocytes retrieved (11 versus 5.5) and a higher clinical pregnancy rate (35.3% versus 11.3%) than patients in group 1 (PSV <10 cm/s), even after controlling for age. CONCLUSION(S) Ovarian stromal blood flow velocity, after pituitary suppression is confirmed, is predictive of ovarian responsiveness and the outcome of IVF treatment.

Abstract
PURPOSE It is a common practice to increase the gonadotropin dose during ovarian stimulation when the estradiol (E2) rise is found to be inadequate. The prognostic impact of the use of this step-up regimen on the outcome of the affected in vitro fertilization (IVF) cycle is the subject of this study. METHODS This is a retrospective analysis of IVF cycles in a series of consecutive patients who required an increase in the gonadotropin dosage during the stimulation phase because of inadequate E2 rise. Controls consisted of patients in whom the dose was not increased. After 4 days of stimulation, the gonadotropin dosage was increased if E2 levels failed to rise by 70% every 2 days. Outcome was defined in terms of maximum E2 level, number of follicles at aspiration, number of oocytes obtained, fertility rate, and pregnancy rate and was compared in study and control patients. Pregnancy was defined by sonographic demonstration of cardiovascular activity. RESULTS One hundred forty-five patients were analyzed. A step-up regimen was used in 35 patients (24.1%). Patients who required the step-up dosing had significantly lower peak E2 levels (1373 vs 1828 pg/ml; P < 0.005), fewer follicles measuring greater than 16 mm (7.2 vs 9.7; P < 0.003), and fewer oocytes recovered (8.3 vs 11.2; P < 0.009). The fertilization rate (67.6 vs 64.2%) was not significantly different. The pregnancy rate (8.5 vs 32.7%; P < 0.004) was significantly lower in the group requiring the step-up regimen. CONCLUSIONS The utilization of a step-up regimen during an IVF treatment cycle is a predictor of a poor outcome for the specific IVF cycle. As this information is available before retrieval, consideration of cycle cancellation may be appropriate.

Abstract
OBJECTIVE To study the outcome in poor responders to three ampules (225 IU) of hMG per day in subsequent IVF treatment cycles in which six ampules (450 IU)of hMG per day were administered. DESIGN Retrospective chart review. SETTING Academic tertiary center. PATIENTS Between January 1988 and May 1995, 126 poor response patients had a first treatment cycle on three ampules and a second cycle on six ampules of hMG per day. MAIN OUTCOME MEASURES Numbers of follicles, oocytes, and embryos, and pregnancy rates. RESULTS On six ampules, patients had significantly more follicles and oocytes. The number of embryos did not differ significantly. The pregnancy rate on six ampules were low (3.2% pregnancies per cycle started). CONCLUSION Poor responders do not benefit from high-dose hMG stimulation; their reproduction outcome is poor.

Abstract
OBJECTIVE To examine the effect of high doses of gonadotropins on IVF outcome in normal (intermediate) responders. DESIGN Retrospective analysis of patients undergoing IVF therapy from 1990 to 1994 at our institution. SETTING Academic tertiary center. PATIENTS A homogeneous group of women that consisted of intermediate responders examined in their initial attempt and who received differing amounts of gonadotropins were examined. INTERVENTIONS All patients were stimulated using a combination of a GnRH-agonist and FSH and hMG and were allocated into two groups, based on the amount of gonadotropin administered initially (four or six ampules). MAIN OUTCOME MEASURES Implantation and pregnancy (clinical and ongoing) rates were compared. RESULTS There were no significant differences between patients receiving high doses versus those patients receiving lower doses of gonadotropins with regard to implantation and pregnancy rates. CONCLUSIONS We conclude that high doses of gonadotropins have no detrimental effect on IVF outcome in normal (intermediate) responders.
