Abstract
A variety of protocols have evaluated the use of several forms of gonadotropins in controlled ovarian stimulation (COS). We aim to review the evolving trends on the use of gonadotropins human chorionic gonadotropin (hCG), follicle-stimulating hormone (FSH) and luteinizing hormone (LH) over time and their combinations in COS for patients who undergo assisted reproductive techniques (ART) protocols. A meticulous search of three electronic databases was performed for articles published in the field up to September 2020. The administration of hCG seems a promising alternative to conventional modalities for COS related to the enhancement of LH activity. The use of gonadotropins was associated with significantly elevated pregnancy rates that ranged from 20.8% to 46.2%. However, the currently available outcomes with regards to oocytes retrieved, number of embryos are still conflicting. A potential beneficial effect was observed by the majority of the studies in terms of the number of embryos and implantation rates, which is, however, highly affected by the type of protocol used (gonadotropin-releasing hormone [GnRH] agonist or antagonist). Further studies are warranted to elucidate the exact pathways of action of gonadotropins in controlled ovarian stimulation to attain the optimal effect.

A Randomized Controlled Trial on the Efficacy and Safety of Low-Dose hCG in a Short Protocol with GnRH Agonist and Ovarian Stimulation with Recombinant FSH (rFSH) During the Follicular Phase in Infertile Women Undergoing ART. Reprod Sci 2021; 29:497-505. [PMID: 34254280 PMCID: PMC8275065 DOI: 10.1007/s43032-021-00683-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2021] [Accepted: 06/25/2021] [Indexed: 11/25/2022]
Abstract
Τhis study aims to investigate whether the addition of low-dose hCG throughout stimulation in infertile women undergoing IVF improves IVF outcome parameters. This is a prospective, multicenter, randomized, double-blind, placebo-controlled, Phase IIIb clinical study, conducted in three university IVF units. We studied whether the addition of 100 IU hCG/day to a short GnRH agonist IVF protocol from the onset of the follicular phase (group 1, n=40) or placebo (group 2, n=41) had any impact on the number of high-quality transferred embryos at day 2 and clinical pregnancy rates. The comparison encompassed descriptive statistics, and univariate and multivariate analyses. Concerning the primary outcomes, we found no differences in both the number of high-quality embryos (≥2) at day 3 [21/40 (52.5%) vs. 14/41 (34.2%), p=0.095] and clinical pregnancy rates [10/40 (25%) vs. 10/41 (24.4%), p=0.949], respectively. Similarly, there were no differences concerning the secondary outcomes preset for this trial. According to the results of the multivariate logistic regression analysis, no significant associations were noted for primary outcomes (clinical pregnancy: adjusted OR=0.89, 95% CI: 0.29–2.75; (≥2 excellent quality embryos at day 3: adjusted OR=0.54, 95% CI: 0.21–1.42, with group 1 set as reference category); similarly, no differences were noted with respect to secondary outcomes, except from the increased odds of ≥2 poor-quality embryos at day 3 occurring in group 2 (adjusted OR= 11.69, 95%CI: 1.29–106.19). The addition of low-dose hCG to a short GnRH agonist protocol for IVF does not improve the number of top-quality embryos and clinical pregnancy rates.

Abstract
OBJECTIVE To assess the effect and timing of human menopausal gonadotropin (HMG) supplementation in advancedage patients with diminished ovarian reserve (DOR) receiving gonadotropin-releasing hormone antagonist protocol. OBJECTIVE A total of 682 patients with DOR aged over 35 years undergoing IVF-ET treatment were included in this study. All the patients underwent a GnRH antagonist protocol, and controlled ovarian stimulation was initiated on day 2-3 of the menstrual cycle with follicle stimulation hormone (FSH). According to the timing of HMG supplementation, the patients were divided into no supplementation group (n=371) without HMG supplementation; early supplementation group (n=139), in which daily HMG supplementation started on the first day till the trigger day; and late supplementation group (n=172), in which HMG supplementation started when the leading follicle reached 10-14 mm in diameter and lasted until the trigger day. The pregnancy outcomes of the patients were compared among the 3 groups. OBJECTIVE The 3 groups showed no significant difference in hCG trigger day E2 and P levels, endometrial thickness, or the number of follicles with comparable fertilization rate and cleavage rate (P>0.05). Gn dose used was the lowest in no supplementation group, and the average number of oocytes retrieved was significantly smaller in early supplementation group than in late supplementation group (P < 0.05). The mean number of mature oocytes and embryos available were significantly higher in late supplementation group than in early supplementation group (P < 0.05). The clinical pregnancy rate of fresh embryo transfer cycle was significantly higher in late supplementation group than in no supplementation group (27.7% vs 45.1%, P < 0.05), but the implantation rate, early miscarriage rate, heterotopic pregnancy rate and live birth rate were comparable among the 3 groups (P>0.05). No significant differences were found among the 3 groups in the implantation rate, clinical pregnancy rate, early miscarriage rate, heterotopic pregnancy rate or live birth rate of the first frozen-thawed embryo transfer cycle with a freeze-all strategy (P>0.05). OBJECTIVE HMG supplementation in the middle and late follicular phase can improve the outcomes of controlled ovarian hyperstimulation and increase the clinical pregnancy rate of fresh embryo transfer cycle in advanced-age patients with DOR undergoing GnRH antagonist protocol.

The Role of FSHR SNPs and AMH in Follicular Fluid and Serum in Ovarian Response during COS: A Pilot Study. Int J Reprod Med 2021; 2021:8685158. [PMID: 33628769 PMCID: PMC7889364 DOI: 10.1155/2021/8685158] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2020] [Revised: 01/06/2021] [Accepted: 01/31/2021] [Indexed: 11/18/2022] Open
Abstract
Background Several studies have investigated on the polymorphism Ser680Asn of FSHR and its use as a predictive indicator of response to an IVF/ICSI protocol. Furthermore, measurement of AMH in serum and follicular fluid is a useful prognostic indicator for the outcome of an assisted reproduction attempt. The purpose of this study is to examine the FSH receptor Ser680Asn polymorphism in combination with AMH levels in both serum and follicular fluid, on the day of oocyte collection. Materials and Methods A total of 32 women who underwent IVF/ICSI were included. Women were grouped into 2 groups: those who received rFSH (n = 11) and those who received hMG (n = 21). Serum AMH was measured on day 3 of the cycle, and AMH in the follicular fluid on the day of oocyte retrieval; the same day peripheral blood was collected for the genotyping of Ser680Asn. Results No statistical significant difference was found between serum AMH and follicular fluid AMH regarding the FSH receptor genotype for the Ser680Asn polymorphism. Regarding the sAMH/ffAMH ratio in the 3 genotypes, the value was lower in Asn/Asn women than Ser/Ser and Ser/Asn, but no statistical difference was obtained. Women who carry the Ser allele have a higher number of follicles, retrieved oocytes, and mature oocytes than women who do not contain the Ser allele. Women with AMH < 2.22 ng/ml presented lower AMH follicular fluid levels and lower serum AMH/follicular fluid AMH ratio in a statistically significant manner. Concerning the genotype for the polymorphism Ser680Asn of FSHR in relation to AMH levels, no statistically significant differences were found. Conclusions The identification of polymorphisms, such as Ser680Asn of FSHR, along with the determination of endocrine markers in the follicular fluid, such as AMH, could lead at some point, to the personalized therapy setting per woman.

Early Follicular Phase Human Chorionic Gonadotropin Addition May Improve the Outcomes of In Vitro Fertilization/Intracytoplasmic Sperm Injection in Patients With "Unpredictable" Poor Response to Gonadotropin-Releasing Hormone Antagonist Protocol. Front Endocrinol (Lausanne) 2021; 12:739773. [PMID: 34707571 PMCID: PMC8544820 DOI: 10.3389/fendo.2021.739773] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2021] [Accepted: 09/03/2021] [Indexed: 12/02/2022] Open
Abstract
PURPOSE To compare the effects of early and mid-late follicular phase administration of 150 IU of human chorionic gonadotropin (hCG) on gonadotropin-releasing hormone (GnRH) antagonist protocol in "unpredictable" poor ovarian response (POR) women undergoing in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) treatment. METHODS A retrospective single-center cohort study was conducted on 67 patients with "unpredictable" POR in their first IVF/ICSI cycle receiving GnRH antagonist protocol. Patients were treated with a second IVF/ICSI cycle using the same GnRH antagonist protocol with the same starting dose of recombinant follicle-stimulating hormone (rFSH) as the first cycle; a daily dose of 150 IU of hCG was administrated on either stimulation day 1 (Group A, n = 35) or day 6 (Group B, n = 32). The number of oocytes retrieved, number of usable embryos, serum level of estradiol (E2) on day of hCG trigger, and clinical pregnant outcomes were studied. RESULTS The addition of 150 IU of hCG on either the first day or sixth day of stimulation increases the serum level of E2, luteinizing hormone (LH), and hCG on the day of hCG trigger. Only the use of 150 IU of hCG on the first stimulation day improved the number of oocytes retrieved, mature of oocytes, and usable embryos, but not the addition of hCG on stimulation day 6. Implantation rate, clinical pregnancy rate, and ongoing pregnancy rate showed an increasing trend in patients receiving 150 IU of hCG in the early phase compared with mid-late phase, even thought there was no statistically significant difference. CONCLUSIONS Our study demonstrated that adding 150 IU of hCG in subsequent GnRH antagonist cycle in "unpredictable" poor responders is associated with the improvement of response to stimulation. Furthermore, early follicular phase addition of 150 IU of hCG significantly increased the number of oocytes retrieved and usable embryos than did the mid-late addition of the same dose.
