Abstract
This retrospective study was performed to investigate the predictive power of the Ovarian Sensitivity Index (OSI) for IVF/ICSI outcomes in infertile patients who were of normal expected ovarian response. A total of 912 infertile patients who underwent GnRH antagonist protocol between January 2017 to August 2019 at the Medical Center for Human Reproduction, Beijing Chao-Yang Hospital were included. All patients completed the full oocyte retrieval cycle and either had a live birth or had no embryos left. OSI was significantly lower in patients with a live birth (196.0 ± 120.4 in the live birth group vs 276.4 ± 235.7 in the non-live birth group, p < 0.001) while follicular output rate (FORT, defined as the ratio of pre-ovulatory follicle count on hCG day x 100/small antral follicle count at baseline) showed no significant difference. Patients were divided into low, average and high OSI groups and analysed in tertiles. From the low to the high OSI group, the cumulative live birth rate (CLBR) decreased dramatically (72.7 vs 67.2 vs 54.8%, p < 0.001). Multivariate regression analysis showed that OSI was an independent factor affecting CLBR (OR: 0.996, 95%CI: 0.995-0.998, p < 0.001) in our study population. In conclusion, OSI can be used as an independent indicator to distinguish fecundity in infertile patients with normal expected ovarian response and is probably more sensitive than FORT.

Abstract
Corifollitropin alpha has been demonstrated to be non-inferior to other gonadotropins in reproductive outcomes. However, its impact on follicular ovarian responsiveness has never been evaluated. Follicular Output Rate (FORT) is an option for objective assessment of the follicular responsiveness. A prospective study was conducted with 306 infertile patients undergoing in vitro fertilisation. Ovarian stimulation protocol was performed with a single dose of 100 μg (<60kg) or 150 μg (≥60kg) corifollitropin alpha in group 1 (n = 147), and 150-300 IU/day human menopausal gonadotropin in group 2 (n = 150). Comparing ovarian stimulation between corifollitropin alpha and human menopausal gonadotropin, no differences regarding FORT were found (40.0% for group 1 versus 40.83% for group 2; p = 0.930). Patients treated with corifollitropin alpha had a higher number of embryos when compared with human menopausal gonadotropin group (3.0 for group 1 versus 2.0 for group 2; p = 0.04). Other secondary outcomes preset were similar between groups. Therefore, corifollitropin alpha can be an excellent option to simplify in vitro fertilisation treatment due to the "patient-friendly" protocol.

Abstract
STUDY QUESTION Does unilateral oophorectomy modify the antral follicular responsiveness to exogenous FSH, assessed by the Follicular Output RaTe (FORT) in normo-ovulating women? SUMMARY ANSWER Antral follicle responsiveness to exogenous FSH, as assessed by the FORT index, is significantly higher in women with a single ovary in comparison with the ipsilateral ovary of age-matched controls. WHAT IS KNOWN ALREADY Growing evidence indicates that the innovative FORT may be a remarkable tool to evaluate the follicle responsiveness to exogenous FSH, independently of the size of the pretreatment cohort of small antral follicles. It is conceivable that in the unclear compensating mechanisms at play in women having undergone unilateral oophorectomy, an increase in the sensitivity of antral follicles to FSH may be involved. To clarify this issue, we decided to investigate whether the responsiveness of follicles to exogenous FSH, as assessed by the FORT, is altered in unilaterally oophorectomized patients. STUDY DESIGN, SIZE, DURATION The study included 344 non-polycystic ovary syndrome, non-endometriotic women, aged 22-43 years old. There were 86 women who had a single ovary as a result of unilateral oophorectomy or adnexectomy (Single Ovary group; average time since surgery: 52 (8-156) months), and each of them was retrospectively matched with three patients having two intact ovaries, according to age (±1 year), year of ovarian stimulation, and FSH starting dose (±50 IU) (Control group, n = 258). PARTICIPANTS/MATERIALS, SETTING, METHODS Serum anti-Mullerian hormone (AMH) levels and total antral follicle count (AFC) (3-12 mm) were assessed on cycle day 3 in both groups. In all patients, follicles were counted before exogenous FSH administration (baseline) and on the day of oocyte trigger (OT) (dOT; preovulatory follicles; 16-22 mm). Antral follicle responsiveness to FSH was estimated in both groups by the FORT, determined by the ratio of the preovulatory follicle count on dOT × 100 to the small AFC at baseline. FORT in the Single Ovary group was compared to the overall FORT considering both ovaries or the index calculated on the ipsilateral ovary of matched controls. MAIN RESULTS AND THE ROLE OF CHANCE Overall, serum AMH levels and total AFC (1.0 (0.5-2.1) vs 1.8 (1.0-3.3), P < 0.005) and (9.0 (6.0-17.0) vs 13.0 (8.0-21.0), P < 0.001, respectively) were lower in the Single Ovary group compared to the Control group. When considering the FORT calculated on the basis of the overall ovarian response in women with two ovaries, the results were similar when compared to those obtained in patients unilaterally oophorectomized (30.4% (15.6-50.0) vs 32.5% (14.0-50.0), respectively). Interestingly, the comparison of FORT between women with a single ovary and the ipsilateral ovary of age-matched controls, revealed, after adjustment for AMH and AFC, a significantly higher ratio after unilateral oophorectomy (32.5% (14.8-50.0) vs 25.0% (10.0-50.0), P < 0.002, respectively). LIMITATIONS, REASONS FOR CAUTION This study was based on retrospective data in a limited population. In addition, the FORT index has inherent limitations due to its indirect assessment of follicular responsiveness to FSH. WIDER IMPLICATIONS OF THE FINDINGS The present investigation provides evidence that the responsiveness of antral follicles to exogenous FSH is increased in women having undergone unilateral oophorectomy when compared to the ipsilateral ovary of age-matched controls. This is consistent with the implication of a compensating phenomenon that drives the follicular changes in unilaterally oophorectomized patients. Further studies directly assessing the granulosa cell function and the density of FSH receptors in small antral follicles are required to confirm our findings.

Abstract
BACKGROUND Women who have polycystic ovary syndrome (PCOS) with high body mass index (BMI) typically have an attenuated ovarian response and decreased follicular size, which are linked to unfavourable clinical outcomes following in vitro fertilization (IVF) therapy. The follicular output rate (FORT), a qualitative indicator of follicular response, seems to be positively linked to the clinical outcomes of IVF. Progestin-primed ovarian stimulation (PPOS) has become an alternative to gonadotropin-releasing hormone (GnRH) analogues to inhibit the premature luteinizing hormone (LH) surge. As letrozole (LE) shows promise in enhancing ovarian response, we compared PPOS with and without LE for PCOS in high BMI women with a focus on the FORT and associated clinical and pregnancy outcomes. METHODS For the recruited 1508 women, ten variables including AFC; age; basal sex hormone level; BMI; infertility type; period of infertility and number of previous IVF attempts were chosen in the propensity score matching (PSM) model to match 1374 women who taken the MPA+ hMG protocol with 134 women who received the MPA+ hMG+ LE treatment at a 1:1 ratio. FORT was selected as the primary outcome measure. The number of oocytes retrieved, viable embryos, hMG dosage, duration, oocyte maturity rate, fertilization rate, and implantation rate were established as secondary outcomes. RESULTS FORT was substantially elevated in the MPA+hMG+LE group compared with the MPA+hMG group (61% [35%, 86%] vs. 40% [25%, 60%], P <.001). Interestingly, the LE cotreatment group had a considerably lower mature oocyte rate despite having a similar number of mature oocytes and embryos recovered. The average hMG dosages and durations in the study group were similar to those in the control group. The implantation rate in the study group was numerically higher but without statistic significant than that in the control groups (43.15% (107/248) vs. 38.59% (115/298), OR 1.008, 95% CI 0.901-1.127; P >.05). CONCLUSION The effect of LE combined with PPOS on FORT is better than the effect of the standard PPOS treatment in women with PCOS and a high BMI, but there is no substantially beneficial impact on pregnancy outcomes or the cycle features of COS, including consumption of hMG.

Abstract
OBJECTIVE We aim to explore the effects of follicular output rate (FORT) on cumulative clinical pregnancy rate (CCPR) and cumulative live birth rate (CLBR) in polycystic ovary syndrome (PCOS) patients with different characteristics undergoing in vitro fertilization (IVF) treatment. METHODS This retrospective study analyzed 454 patients with PCOS undergoing their first IVF cycle at our center from January 2016 to December 2020. FORT was calculated as pre-ovulatory follicle count (PFC) × 100/antral follicle count (AFC). Multivariate regression analyses were conducted to explore the relationships between FORT and CCPR and CLBR. Curve fitting and threshold effect analyses were established to find nonlinear relationships. Effect modification in different subgroups were examined by stratification analyses. RESULTS Based on the FORT values, individuals were classified into the following three groups: low-FORT group, middle-FORT group and high-FORT group. Multivariate regression analyses revealed that FORT was an independent factor affecting the CCPR and CLBR significantly (OR = 1.015, 95% CI: 1.001, 1.030 and OR = 1.010, 95% CI:1.001, 1.020). Curve fitting and threshold effect analyses showed that the CCPR and CLBR had a positive correlation with FORT when the FORT was less than 70% (OR = 1.039, 95% CI: 1.013, 1.065 and OR = 1.024, 95% CI: 1.004, 1.044). Stratification analyses showed that the CLBR increased by 1.3% with each additional unit of FORT for patients with hyperandrogenic manifestations (OR = 1.013, 95% CI: 1.001, 1.025). Compared with the low-FORT group, in the high-FORT group, CCPR increased 1.251 times for patients with polycystic ovarian morphology, while CCPR and CLBR increased 1.891 times and 0.99 times for those with ovulation disorder, respectively (OR = 2.251, 95% CI: 1.008, 5.028 and OR = 2.891, 95% CI: 1.332, 6.323 and OR = 1.990, 95% CI: 1.133, 3.494). CONCLUSION In patients with PCOS, cumulative IVF outcomes have a positive correlation with FORT when the FORT is less than 70%. For PCOS patients with polycystic ovarian morphology, ovulation disorder or hyperandrogenic manifestations, a high FORT could be conductive to achieving better pregnancy outcomes.

Abstract
To assess the relation between oocytes yield including total retrieved oocytes (O)c and total mature oocytes (MII) relative to the antral follicular count (AFC) (3–9 mm in diameter) and relative to anti-müllerian hormone (AMH) ng/mL level: Oc/AFC, MII/AFC, Oc/AMH, and MII/AMH, respectively, and ART outcomes. We included retrospectively 264 IVF cycles after the first embryo transfer (ET) and after the cumulative ET (CET). The implantation rate (IR) and the live birth rate (LBR) after first ET were 31 ± 39% and 32.6%, respectively, and after CET 35 ± 38% and 45.1%, respectively. There was a significantly higher average of Oc/AFC and MII/AFC when live birth (LB) occurred after the first ET (0.82 ± 0.4 vs. 0.71 ± 0.35 and 0.57 ± 0.4 vs. 0.68 ± 0.3, respectively, P < 0.05). We reported a significantly higher average of MII/AFC when LB occurred after CET (0.66 ± 0.3 vs. 0.56 ± 0.30, P = 0.02) in comparison to the group where no LB was obtained. Increased Oc/AFC and MII/AFC ratios were associated with the occurrence of LB and increased IR after first ET (P < 0.05). Increased MII/AFC ratio was associated with the occurrence of LB and IR after CET (P = 0.02 and P = 0.04, respectively). After age-adjusted multivariate analyses, all these trends were confirmed (P < 0.05) except for the effect of MII/AFC ratio on IR after CET. In conclusion, Oc/AMH and MII/AMH ratios have no effect on the occurrence of LBR or on IR after first ET or CET at either age grouping. Ratios Oc/AFC and MII/AFC seem promising indicators to assess ovarian response.

Abstract
OBJECTIVE To investigate ovarian sensitivity in subgroups of patients with a low prognosis, as defined by the POSEIDON criteria, undergoing in vitro fertilization treatment and measures to improve ovarian sensitivity in these patients. DESIGN We conducted a retrospective cohort analysis. SETTING The study was conducted at an IVF clinic in a public hospital. PATIENTS A total of 32,128 fresh IVF cycles from January 2014 to October 2018 at a single IVF clinic were included in the analysis. Patients with a low prognosis were categorized into four groups based on the POSEIDON criteria. INTERVENTIONS None. MAIN OUTCOME MEASURE The primary outcome measures were the follicular output rate (FORT) and the follicle-to-oocyte index (FOI). RESULTS The FORTs in the order from the highest to the lowest were 1.18 in group 3, 0.98 in group 4, 0.76 in group 1, and 0.68 in group 2. The trend in the FOI values was consistent with that in the FORTs. Among patients with poor ovarian sensitivity, 58.41% of patients with FORTs ≥ 0.30 in the second cycle underwent an adjustment to the ovarian stimulation (OS) protocol and 41.59% underwent an adjustment to the gonadotropin (Gn) starting dose. Among patients with normal ovarian sensitivity, 43.56% of those with FORTs ≥ 0.80 in the second cycle underwent an adjustment to the OS protocol and 56.44% underwent an adjustment to the Gn starting dose. CONCLUSION Ovarian sensitivity was the highest in group 3 (young women with poor ovarian reserve), followed by groups 4 (women at advanced age with poor ovarian reserve) and 1 (young women with good ovarian reserve), and it was the lowest in group 2 (women at advanced age with good ovarian reserve). For patients with poor ovarian sensitivity, it is preferred to recommend an adjustment to the OS protocol, while for those with normal ovarian sensitivity, adjusting the Gn starting dose is preferred.

Abstract
Objective This study aimed to examine the relationship between the follicular output rate (FORT) and clinical outcomes in patients with polycystic ovarian syndrome (PCOS). Methods A total of 841 patients with PCOS undergoing in vitro fertilization-embryo transfer (IVF-ET) were divided into three groups according to their FORT (low, middle, and high). Controlled ovarian hyperstimulation and clinical outcomes were compared retrospectively. Results Serum estradiol levels on the day of human chorionic gonadotropin (3780.5, 3599.9, and 3375.7 pg/mL) and the number of retrieved oocytes (17.5, 16.1, and 14.8) decreased from the high to low FORT groups. Pre-ovulatory follicle counts were significantly higher in the high FORT group than in the middle and low FORT groups. The number of retrieved oocytes, high-quality embryo rate, and clinical pregnancy rate decreased from the high to low FORT groups. The incidence of moderate and severe ovarian hyperstimulation syndrome (OHSS) in the middle FORT group was significantly lower than that in the high and low FORT groups. Conclusions FORT may be used to predict clinical outcomes of IVF/intracytoplasmic sperm injection-embryo transfer in patients with PCOS. Efforts should be made to prevent OHSS in patients with PCOS and a high or low FORT in controlled ovarian hyperstimulation cycles.

Abstract
The management of low prognosis patients in ART represents a challenge for reproductive specialists. Different profiles and biologic characteristics have been identified among these patients. Indeed, while poor ovarian response can be seen in patients with impaired ovarian reserve, others, identified as hypo-responders, show unexpected poor or suboptimal response to controlled ovarian stimulation despite satisfying ovarian parameters. These hypo-responders are associated during FSH stimulation to slow initial responses in terms of estradiol levels and follicle growth, longer stimulations, and/or greater cumulative FSH doses. Hence, it appears that ovarian sensitivity to gonadotropins differs from a patient to another, and plays a determinant role on ovarian response to stimulation. Although precise mechanisms remain to be elucidated, increasing evidence suggests that ovarian sensitivity to FSH could be influenced by the presence of genetic mutations or single nucleotide polymorphisms of gonadotropins and their receptors. Evaluating ovarian sensitivity to FSH therefore appears as a key element to improve IVF success rates in these low prognosis patients and open new treatment perspectives. Since the traditional ovarian markers currently used are not sufficient to accurately reflect ovarian response to FSH, a tool to assess ovarian sensitivity to gonadotropin stimulation was required. The present review aims to present Follicular Output Rate (FORT) as an efficient quantitative and qualitative marker of ovarian responsiveness to gonadotropins, discuss the underlying mechanisms of impaired sensitivity to FSH and the possible FORT implications for Poseidon criteria.
