Abstract
Physical and emotional burdens during the journey of infertile people through assisted reproductive technologies are sufficient to justify the efforts in developing patient-friendly treatment strategies. Thus, shorter duration of ovarian stimulation protocols and the need for less injections may improve adherence, prevent mistakes, and reduce financial costs. Therefore, the sustained follicle-stimulating action of corifollitropin alfa may be the most differentiating pharmacokinetic characteristic among available gonadotropins. In this paper, we gather the evidence on its use, aiming to provide the information needed for considering it as a first choice when a patient-friendly strategy is desired.

Abstract
OBJECTIVE To investigate whether minimal ovarian stimulation (mOS) is as effective as conventional ovarian stimulation (cOS) for older women belonging to different groups according to the Poseidon criteria. MATERIAL AND METHODS Observational retrospective multicentre cohort including women from Poseidon's groups 2 and 4 that underwent in vitro fertilization (IVF). We performed a mixed-effects logistic regression model, adding as a random effect the patients and the stimulation cycle considering the dependence of data. Survival curves were employed as a measure of the cumulative live birth rate (CLBR). The primary outcomes were live birth rate per embryo transfer and CLBR per consecutive embryo transfer and oocyte consumed until a live birth was achieved. RESULTS A total of 2002 patients underwent 3056 embryo transfers (mOS = 497 and cOS = 2559). The live birth rates per embryo transfer in mOS and cOS showed no significant difference in both Poseidon's groups. Likewise, the logistic regression showed similar live birth rates between the two protocols in Poseidon's groups 2 (OR 1.165, 95% CI 0.77-1.77; p = 0.710) and 4 (OR 1.264 95% CI 0.59-2.70; p = 0.387). However, the survival curves showed higher CLBR per oocyte in women that received mOS (Poseidon group 2: p < 0.001 and Poseidon group 4: p = 0.039). CONCLUSIONS Minimal ovarian stimulation is a good alternative to COS as a first-line treatment for patients belonging to Poseidon's groups 2 and 4. The number of oocytes needed to achieve a live birth seems inferior in mOS strategy than cOS.

[PMID: 33742206 DOI: 10.1093/humupd/dmab008] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2020] [Revised: 01/30/2021] [Indexed: 11/14/2022] Open
Abstract
BACKGROUND Since its introduction in the 1980s, oocyte donation (OD) has been largely integrated into ART. Lately, both demand and the indications for OD have increased greatly. Oocyte donors are healthy and potentially fertile women undergoing voluntarily ovarian stimulation (OS). Selection of the optimal type of stimulation is of paramount importance in order to achieve the most favourable outcomes for the oocyte recipients, but most importantly for the safety of the oocyte donors. OBJECTIVE AND RATIONALE This is the first systematic review (SR) with the objective to summarize the current evidence on OS in oocyte donors. The scope of this SR was to evaluate the OD programme by assessing four different aspects: how to assess the ovarian response prior to stimulation; how to plan the OS (gonadotrophins; LH suppression; ovulation trigger; when to start OS); how to control for the risk of ovarian hyperstimulation syndrome (OHSS) and other complications; and the differences between the use of fresh versus vitrified donated oocytes. SEARCH METHODS A systematic literature search was conducted in May 2020, according to PRISMA guidelines in the databases PubMed and Embase, using a string that combined synonyms for oocytes, donation, banking, freezing, complications and reproductive outcomes. Studies reporting on the safety and/or efficacy of OS in oocyte donors were identified. The quality of the included studies was assessed using ROBINS-I and ROB2. Meta-analysis was performed where appropriate. Data were combined to calculate mean differences (MD) for continuous variables and odd ratios (OR) for binary data with their corresponding 95% CIs. Heterogeneity between the included studies was assessed using I2 and tau statistics. OUTCOMES In total, 57 manuscripts were selected for the review, out of 191 citations identified. Antral follicle count and anti-Müllerian hormone levels correlate with ovarian response to OS in OD but have limited value to discriminate donors who are likely to show either impaired or excessive response. Five randomized controlled trials compared different type of gonadotrophins as part of OS in oocyte donors; owing to high heterogeneity, meta-analysis was precluded. When comparing different types of LH control, namely GnRH antagonist versus agonist, the studies showed no differences in ovarian response. Use of progesterone primed ovarian stimulation protocols has been evaluated in seven studies: the evidence has shown little or no difference, compared to GnRH antagonist protocols, in mean number of retrieved oocytes (MD 0.23, [95% CI 0.58-1.05], n = 2147; 6 studies; I2 = 13%, P = 0.33) and in clinical pregnancy rates among recipients (OR 0.87 [95% CI 0.60-1.26], n = 2260, I2 = 72%, P < 0.01). There is insufficient evidence on long-term safety for babies born. GnRH agonist triggering is the gold standard and should be used in all oocyte donors, given the excellent oocyte retrieval rates, the practical elimination of OHSS and no differences in pregnancy rates in recipients (four studies, OR 0.86, 95%CI 0.58-1.26; I2 = 0%). OS in OD is a safe procedure with a low rate of hospitalization after oocyte retrieval. The use of a levonorgestrel intrauterine device or a progestin contraceptive pill during OS does not impact the number of oocytes retrieved or the clinical pregnancy rate in recipients. Ultrasound monitoring seems enough for an adequate follow up of the stimulation cycle in OD. Use of fresh versus vitrified donated oocytes yielded similar pregnancy outcomes. WIDER IMPLICATIONS This update will be helpful in the clinical management of OS in OD based on the most recent knowledge and recommendations, and possibly in the management of women under 35 years undergoing oocyte vitrification for social freezing, owing to the population similarities. More clinical research is needed on OS protocols that are specifically designed for OD, especially in term of the long-term safety for newborns, effective contraception during OS, and treatment satisfaction.

Abstract
To study whether ovarian response to corifollitropin among oocyte donors (OD) is different when oral desogestrel (DSG) is used to block the luteinizing hormone (LH) surge when compared to GnRH-antagonist use. This is a retrospective, cohort study at a private, university-based, IVF center including 35 OD. Patients underwent two stimulation cycles under corifollitropin alfa (CFT), one under an antagonist and another under DSG, between February 2015 and May 2017. In antagonist cycles, daily ganirelix was administered since a leading follicle reached 14 mm. In the DSG cycles, daily oral DSG was prescribed. The main outcome measure was oocytes retrieved. Compared to antagonist cycles, cycles under DSG received fewer injections (10.3 ± 2.8 vs. 5.0 ± 2.1, p < .001), nominally lower total supplementary gonadotropin dose (497.4 ± 338.9I U vs. 442.9 ± 332.8 IU, p=.45) with a lower total cost of medication (1018.6 ± 191.0€ vs. 813.8 ± 145.9€, p<.001). There were no differences in the total number of retrieved oocytes between groups (17.4 ± 7.5 vs. 18.6 ± 8.9, p=.34). In the corresponding oocyte recipients, clinical pregnancy rate was similar between groups: 52.0% vs. 58.6%, respectively (p=.78). ODs' stimulation's response under DSG is similar when compared to (17.4 ± 7.5 vs. 18.6 ± 8.9, p=.34) but associated with less injections and lower medication costs. The main advantage of this strategy is its simplicity, an aspect of utmost importance in the management of ODs.

Abstract
OBJECTIVE To evaluate the effectiveness of corifollitropin alfa in improving the success of IVF. DESIGN Systematic review and meta-analysis. SETTING Not applicable. PATIENT(S) Infertile women undergoing conventional IVF or intracytoplasmic sperm injection (ICSI). INTERVENTION(S) Randomized controlled trials (RCTs) of infertile women undergoing a single IVF/ICSI cycle with either corifollitropin alfa or a conventional ovarian stimulation protocol based on daily injections. The review protocol was registered in PROSPERO before starting the data extraction (CRD42018088605). MAIN OUTCOME MEASURE(S) Primary outcomes were live birth rate and/or ongoing pregnancy rate. Clinical pregnancy rate, miscarriage rate, multiple pregnancies, number of oocytes and embryos obtained, cancellation rate, and rate of ovarian hyperstimulation syndrome and ectopic pregnancy were considered as secondary outcomes. RESULT(S) Eight randomized controlled trials were included; 2,345 women were assigned to the intervention group and 1,995 to the control group. The analysis of 4,340 IVF cycles did not reveal any difference in live birth rate and/or ongoing pregnancy rate between groups (risk ratio [RR], 0.92; 95% confidence interval [CI], 0.80-1.05). Similarly, no difference was found in clinical pregnancy rate (RR, 0.96; 95% CI, 0.88-1.05; I2 = 0%), miscarriage rate (RR, 0.94; 95% CI, 0.71-1.25; I2 = 0%), or multiple pregnancy rate (RR, 1.22; 95% CI, 0.99-1.50; I2 = 0%). Also, the rates of cycle cancellation, ovarian hyperstimulation syndrome, and ectopic pregnancy were similar in both groups. Sensitivity and subgroup analyses did not provide statistical changes to pooled results. CONCLUSION(S) Corifollitropin alfa seems to be an alternative for daily recombinant FSH injections in normal and poor responder patients undergoing ovarian stimulation in IVF/ICSI treatment cycles.

Abstract
This study presents an economic assessment of controlled ovarian stimulation in assisted reproductive technology procedures in Spain, comparing the use of corifollitropin alfa and various forms of recombinant follicle-stimulating hormone (rFSH) in women of advanced maternal age. A cost-minimization analysis (CMA) was performed to assess the cost per cycle of controlled controlled ovarian stimulation, including only direct costs associated with the stimulation phase. The CMA was based on the population characteristics, the protocol, and the results obtained from the PURSUE study, taking into account 9 days of controlled controlled ovarian stimulation and 300 IU rFSH/day. The primary analysis included pharmacological costs alone. Different scenarios were evaluated including various doses and possible additional days (0-5) for rFSH. For the alternative analyses, the total costs (direct pharmacological costs, costs of visits and follow-up tests, and any additional pharmacological costs) were considered in both the private and public sectors. Treatment with corifollitropin alfa resulted in a lower pharmacological cost compared with rFSH (€757.25 and €950.30, respectively), creating a saving of approximately -20%. The results of the scenario analyses showed that corifollitropin alfa reduced the pharmacological cost of controlled ovarian stimulation in comparison with daily administration of doses ≥ 250 IU rFSH (considering same daily dose for all days), regardless of the additional days required (7-12 days) (average -€223; range -€488 to -€44). In conclusion, in addition to the efficacy shown in the PURSUE study, the use of corifollitropin alfa results in a decrease in the direct costs associated with controlled ovarian stimulation in older women in Spain.
