ABSTRACT

STUDY QUESTION: Does administration of corifollitropin alfa followed by highly purified (hp) HMG result in higher ongoing pregnancy rates compared with daily recombinant FSH (rFSH) in young poor responders? SUMMARY ANSWER: Corifollitropin alfa followed by hp-HMG does not increase ongoing pregnancy rates compared with rFSH in young poor responders, although more supernumerary cryopreserved embryos were obtained with corifollitropin alfa and hp-HMG. WHAT IS KNOWN ALREADY: Poor ovarian response remains one of the main therapeutic challenges in women undergoing ovarian stimulation, given that very low live birth rates of 6% have been reported in this particular group of infertile patients. Nevertheless, concerns have been raised that a degree of heterogeneity remains, as the prognostic effect of individual factors is still unclear, particularly for the young poor responder group. The rationale for conducting the current randomized trial was based on the results of a previous pilot study demonstrating promising results with the administration of hp-HMG following corifollitropin alpha in women younger than 40 years of age, fulfilling the 'Bologna' criteria. STUDY DESIGN, SIZE, DURATION: A multicenter, phase III, superiority, randomized trial was conducted using a parallel two-arm design. The study included 152 patients younger than 40 years old and fulfilling the 'Bologna' criteria for poor ovarian response, from one tertiary referral centre in Europe and one tertiary referral centre in Asia. Enrolment was performed from March 2013 to May 2016. PARTICIPANTS/MATERIALS, SETTING, METHODS: Eligible patients were randomized to either administration of 150 µg corifollitropin alfa followed by 300 IU hp-HMG (Group A) or to 300 IU of daily recombinant FSH (Group B) in a fixed GnRH antagonist protocol. The randomization sequence was created using a computer generated randomization list stratified by centre, using 1:1 allocation. The primary outcome was ongoing pregnancy rate (defined as the presence of an intrauterine gestational sac with an embryonic pole demonstrating cardiac activity at 9-10 weeks of gestation). Secondary outcomes included embryo cryopreservation rates, clinical and biochemical pregnancy rates and number of oocytes retrieved. MAIN RESULTS AND THE ROLE OF CHANCE: Overall, 152 poor ovarian responders defined by the 'Bologna' criteria were included in the study. Using an intention-to treat analysis, the ongoing pregnancy rates did not differ significantly between Group A 11/77 (14.3%) and Group B 11/70 (15.7%), absolute difference: -0.4 (-11.5 to 10.8), OR = 0.9 (0.4-2.4). Biochemical and clinical pregnancy rates, live birth rates and the number of oocytes retrieved were also comparable between the two groups. Nevertheless, more patients in the corifollitropin alfa group had cryopreserved embryos compared to the rFSH group [22 (28.6%) versus 10 (14.3%), OR = 2.4 (1.01-5.5)]. Incidentally, Asian patients had significantly lower cancellation rates compared to European poor responders [2/64 (3.1%) versus 17/83 (20.4%), OR = 0.12 (0.03-0.5)]. This discrepancy could be explained by the fact that Asian women were better prognosis patients than European patients, with significantly lower FSH [9.8 (5.3) versus 11.5 (5.4), P = 0.017] and significantly higher AMH [1.1 (0.9) versus 0.4 (0.3), P-value <0.001] levels. LIMITATIONS, REASONS FOR CAUTION: Ongoing pregnancy rates close to 14% for both treatment groups differ significantly from the hypothesized primary outcome rates used in the power calculation. Therefore, our randomized trial might have been underpowered to detect smaller differences. The use of multiple secondary outcomes and multiple comparisons could have increased a Type 1 error. Finally, although the chance of selection biases remains low given the nature of the infertile population, the open-label design could have been a limitation. WIDER IMPLICATIONS OF THE FINDINGS: Poor ovarian response represents a challenge and although a specific protocol may have increased the number of cryopreserved embryos, no difference was observed in ongoing pregnancy rates. Our study, being one of the largest RCTs in 'Bologna' criteria poor responders, highlights that baseline characteristics may play a crucial role in clinical prognosis of this population. Given that ovarian stimulation using novel protocols does not seem to significantly increase pregnancy rates even in young women, we suggest that future clinical research should focus on increasing the number of recruitable follicles and on oocyte quality rather than evaluating different stimulation protocols.

ABSTRACT

PURPOSE: A recent dose-finding study showed no significant differences in number of mature oocytes, embryos and top-quality embryos when triptorelin doses of 0.2, 0.3 or 0.4 mg were used to trigger final oocyte maturation in oocyte donors co-treated with a gonadotropin-releasing hormone (GnRH) antagonist. This analysis investigated whether triptorelin dosing for triggering final oocyte maturation in oocyte donors induced differences in follicular fluid (FF) hormone levels and granulosa cell gene expression. METHODS: This single-centre, randomised, parallel, investigator-blinded trial was conducted in oocyte donors undergoing a single stimulation cycle at IVFMD, My Duc Hospital, Ho Chi Minh City, Vietnam, from August 2014 to March 2015. A total of 165 women aged 18-35 years with body mass index <28 kg/m2, anti-Müllerian hormone >1.25 ng/mL, and antral follicle count ≥6 were randomised to three different triptorelin doses for trigger. The main outcome was concentration of steroid hormones in FF collected from the first punctured follicle on each side. Moreover, luteinising hormone receptor (LHR), 3ß-hydroxy-steroid-dehydrogenase (3ßHSD) and inhibin-Ba (INHB-A) gene expression in cumulus and mural granulosa cells were investigated in a subset of women from each group. RESULTS: Progesterone and oestradiol levels in FF did not differ significantly by trigger doses; findings were similar for 3ßHSD, LHR and INHB-A gene expression in both cumulus and mural granulosa cells. CONCLUSIONS: In women co-treated with a GnRH antagonist, no significant differences in FF steroid levels and granulosa cell gene expression were seen when different triptorelin doses were used to trigger final oocyte maturation.

ABSTRACT

OBJECTIVE: To determine the optimal GnRH agonist dose for triggering of oocyte maturation in oocyte donors. DESIGN: Single-center, randomized, parallel, investigator-blinded trial. SETTING: IVFMD, My Duc Hospital, Ho Chi Minh City, Vietnam. PATIENT(S): One hundred sixty-five oocyte donors (aged 18-35 years, body mass index [BMI] <28 kg/m(2), antimüllerian hormone level >1.25 ng/mL, and antral follicle count ≥6). INTERVENTION(S): Ovulation trigger with 0.2, 0.3, or 0.4 mg triptorelin in a GnRH antagonist cycle. MAIN OUTCOME MEASURE(S): The primary end point was number of metaphase II oocytes. Secondary end points were fertilization and cleavage rates, number of embryos and top-quality embryos, steroid levels, ovarian volume, and ongoing pregnancy rate (PR) in recipients. RESULT(S): There were no significant differences between the triptorelin 0.2, 0.3, and 0.4 mg trigger groups with respect to number of metaphase II oocytes (16.0 ± 8.5, 15.9 ± 7.8, and 14.7 ± 8.4, respectively), embryos (13.2 ± 7.8, 11.7 ± 6.9, 11.8 ± 7.0), and number of top-quality embryos (3.8 ± 2.9, 3.6 ± 3.0, 4.1 ± 3.0). Luteinizing hormone levels at 24 hours and 36 hours after trigger was significantly higher with triptorelin 0.4 mg versus 0.2 mg and 0.3 mg (9.8 ± 7.1 IU/L vs. 7.3 ± 4.1 IU/L and 7.2 ± 3.7 IU/L, respectively; 4.6 ± 3.2 IU/L vs. 3.2 ± 2.3 IU/L and 3.3 ± 2.1 IU/L, respectively. Progesterone level at oocyte pick-up +6 days was significantly higher in the 0.4-mg group (2.2 ± 3.7 ng/ml) versus 0.2 mg (1.1 ± 1.0 ng/ml) and 0.3 mg (1.2 ± 1.6 ng/ml). One patient developed early-onset severe ovarian hyperstimulation syndrome (OHSS). CONCLUSION(S): No significant differences between triptorelin doses of 0.2, 0.3, and 0.4 mg used for ovulation trigger in oocyte donors were seen with regard to the number of mature oocytes and top-quality embryos. CLINICAL TRIAL REGISTRATION NUMBER: NCT02208986.

ABSTRACT

LH and FSH have complementary functions in ensuring optimal oocyte maturation and ovulation. In women undergoing assisted reproduction technology protocols with gonadotrophin-releasing hormone analogues, LH and FSH concentrations are reduced. While FSH use in assisted reproduction technology is well established, there is no published consensus on the need for exogenous LH in Asian patients. Having reviewed the concept of the LH therapeutic window and differences between recombinant human LH (r-HLH) and human menopausal gonadotrophin, a consensus was reached on which patient subgroups may benefit from LH supplementation. Adjuvant r-HLH gives clinicians precise control over the dose of LH bioactivity administered to target the therapeutic window. The use of r-HLH is recommended in women with poor response in a previous cycle or suboptimal follicular progression in a current cycle by day 6-8 of stimulation. r-HLH should also be considered in women at risk of suboptimal response, specifically age > 35 years. Other risk markers that suggest the need for LH supplementation, which include baseline/day-6 serum LH and anti-Müllerian hormone concentrations, antral follicle count and LH polymorphisms require further research and verification. For measurement of LH response adequacy, the monitoring of follicular progression, oestradiol concentrations and endometrial thickness is recommended.
