Good practice recommendations on add-ons in reproductive medicine†. Hum Reprod 2023; 38:2062-2104. [PMID: 37747409 PMCID: PMC10628516 DOI: 10.1093/humrep/dead184] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Indexed: 09/26/2023] Open
Abstract
STUDY QUESTION Which add-ons are safe and effective to be used in ART treatment? SUMMARY ANSWER Forty-two recommendations were formulated on the use of add-ons in the diagnosis of fertility problems, the IVF laboratory and clinical management of IVF treatment. WHAT IS KNOWN ALREADY The innovative nature of ART combined with the extremely high motivation of the patients has opened the door to the wide application of what has become known as 'add-ons' in reproductive medicine. These supplementary options are available to patients in addition to standard fertility procedures, typically incurring an additional cost. A diverse array of supplementary options is made available, encompassing tests, drugs, equipment, complementary or alternative therapies, laboratory procedures, and surgical interventions. These options share the common aim of stating to enhance pregnancy or live birth rates, mitigate the risk of miscarriage, or expedite the time to achieving pregnancy. STUDY DESIGN, SIZE, DURATION ESHRE aimed to develop clinically relevant and evidence-based recommendations focusing on the safety and efficacy of add-ons currently used in fertility procedures in order to improve the quality of care for patients with infertility. PARTICIPANTS/MATERIALS, SETTING, METHODS ESHRE appointed a European multidisciplinary working group consisting of practising clinicians, embryologists, and researchers who have demonstrated leadership and expertise in the care and research of infertility. Patient representatives were included in the working group. To ensure that the guidelines are evidence-based, the literature identified from a systematic search was reviewed and critically appraised. In the absence of any clear scientific evidence, recommendations were based on the professional experience and consensus of the working group. The guidelines are thus based on the best available evidence and expert agreement. Prior to publication, the guidelines were reviewed by 46 independent international reviewers. A total of 272 comments were received and incorporated where relevant. MAIN RESULTS AND THE ROLE OF CHANCE The multidisciplinary working group formulated 42 recommendations in three sections; diagnosis and diagnostic tests, laboratory tests and interventions, and clinical management. LIMITATIONS, REASONS FOR CAUTION Of the 42 recommendations, none could be based on high-quality evidence and only four could be based on moderate-quality evidence, implicating that 95% of the recommendations are supported only by low-quality randomized controlled trials, observational data, professional experience, or consensus of the development group. WIDER IMPLICATIONS OF THE FINDINGS These guidelines offer valuable direction for healthcare professionals who are responsible for the care of patients undergoing ART treatment for infertility. Their purpose is to promote safe and effective ART treatment, enabling patients to make informed decisions based on realistic expectations. The guidelines aim to ensure that patients are fully informed about the various treatment options available to them and the likelihood of any additional treatment or test to improve the chance of achieving a live birth. STUDY FUNDING/COMPETING INTEREST(S) All costs relating to the development process were covered from ESHRE funds. There was no external funding of the development process or manuscript production. K.L. reports speakers fees from Merck and was part of a research study by Vitrolife (unpaid).

[PMID: 37257719 DOI: 10.1016/j.fertnstert.2023.05.163] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Revised: 05/20/2023] [Accepted: 05/23/2023] [Indexed: 06/02/2023]
Abstract
OBJECTIVE To examine the developmental competence of immature oocytes in stimulated cycles, that matured after rescue in vitro maturation (IVM) compared with their sibling in vivo matured oocytes. DESIGN Retrospective cohort study. SETTING IVF clinic. PATIENTS A total of 182 patients underwent 200 controlled ovarian stimulation cycles with intracytoplasmic sperm injection cycles in which immature oocytes were retrieved and at least one mature oocyte was obtained through rescue IVM. INTERVENTION In vitro culture of immature germinal vesicle (GV) and metaphase I (MI) oocytes, retrieved in stimulated cycles. MAIN OUTCOME MEASURES Fertilization rate, cleavage rate, blastulation rate, ploidy of embryos evaluated using preimplantation genetic testing for aneuploidy, morphokinetic parameters and pregnancy outcomes. RESULTS In total, 2,288 oocytes were retrieved from 200 cycles. After denudation, 1,056 of the oocytes (46% ± 16%) were classified as metaphase II (MII). A total of 333/375 (89%) of MI oocytes and 292/540 (54%) of GV oocytes matured overnight and underwent intracytoplasmic sperm injection. The fertilization rates of matured oocytes from MI rescue IVM (R-MI) and from GV rescue IVM (R-GV) were comparable with those of their sibling MII oocytes (71% vs. 66%; 66% vs. 63%, respectively). Early cleavage rates (80% ± 35% vs. 92% ± 20%; 80% ± 42% vs. 95% ± 28%, respectively) and blastulation rates (32 ± 40% vs. 62 ± 33%; 24 ± 37% vs. 60 ± 35%, respectively) were significantly decreased in rescue IVM matured oocytes (R-oocytes)-derived zygotes, but the blastocyst (BL) euploidy rate and "good quality" BL rate were comparable with those of MII sibling-derived embryos. In addition, rescue IVM embryos showed significantly higher levels of multinucleation at the 2- and 4-cell stages, as well as higher rates of zygote direct cleavage from one to 3 to 4 cells. Overall, 21 transfers of rescue IVM embryos resulted in 3 healthy live births. CONCLUSIONS For patients with a low maturation rate and/or low numbers of mature oocytes at retrieval, rescue IVM may contribute more competent oocytes and additional viable BLs for transfer from the same stimulation cycle, maximizing the chances for pregnancy and live birth.

[PMID: 36567150 DOI: 10.1016/j.rbmo.2022.11.012] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2022] [Revised: 10/26/2022] [Accepted: 11/21/2022] [Indexed: 11/27/2022]
Abstract
RESEARCH QUESTION Is the DuoStim strategy an effective alternative to two conventional ovarian stimulation cycles in poor-prognosis patients undergoing preimplantation genetic testing for aneuploidies (PGT-A) to improve euploidy rates and obtain the first euploid embryo in less time? DESIGN This randomized controlled trial was performed at IVI Madrid between June 2017 and December 2020 and included 80 patients with a suboptimal profile aged 38 or older undergoing PGT-A cycles. Patients were blindly randomized into two groups: 39 women underwent two ovarian stimulations in consecutive cycles (control group), whereas the double stimulation strategy was applied to 41 women (DuoStim group). The main outcome was the euploidy rate in each group. The secondary outcomes were the time it took to obtain a euploid embryo and the main cycle outcomes. RESULTS The baseline characteristics of the patients were similar. No differences were found between the control group and the DuoStim group in the mean days of stimulation (21.3 ± 1.6 versus 23.0 ± 1.4, P = 0.10), total gonadotrophins (4005 ± 450 versus 4245 ± 430, P = 0.43), metaphase II oocytes (8.7 ± 1.8 versus 6.8 ± 1.7, P = 0.15) or euploid embryos obtained (0.8 ± 0.4 versus 0.6 ± 0.4, P = 0.45). The euploid rate per randomized patient (ITT) was 16.1% in the control group versus 22.7% in the DuoStim group, with P-values of 0.371, and the euploidy rate per patient treated was 39.0% versus 45.7% in the control versus DuoStim groups. However, there was a significant difference in the average number of days it took to obtain a euploid blastocyst, favouring the DuoStim group (44.1 ± 2.0 versus 23.3 ± 2.8, P < 0.001). CONCLUSIONS The use of the DuoStim strategy in poor-prognosis patients undergoing PGT-A cycles maintains a similar euploidy rate while reducing the time required to obtain a euploid blastocyst.

Ultrastructural Evaluation of the Human Oocyte at the Germinal Vesicle Stage during the Application of Assisted Reproductive Technologies. Cells 2022; 11:cells11101636. [PMID: 35626673 PMCID: PMC9139706 DOI: 10.3390/cells11101636] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2022] [Revised: 05/06/2022] [Accepted: 05/12/2022] [Indexed: 12/04/2022] Open
Abstract
After its discovery in 1825 by the physiologist J.E. Purkinje, the human germinal vesicle (GV) attracted the interest of scientists. Discarded after laparotomy or laparoscopic ovum pick up from the pool of retrieved mature oocytes, the leftover GV was mainly used for research purposes. After the discovery of Assisted Reproductive Technologies (ARTs) such as in vitro maturation (IVM), in vitro fertilization and embryo transfer (IVF-ET) and intracytoplasmic sperm injection (ICSI), its developing potential was explored, and recognized as an important source of germ cells, especially in the case of scarce availability of mature oocytes for pathological/clinical conditions or in the case of previous recurrent implantation failure. We here review the ultrastructural data available on GV-stage human oocytes and their application to ARTs.

Reprod Biol Endocrinol 2021; 19:183. [PMID: 34893069 PMCID: PMC8662918 DOI: 10.1186/s12958-021-00868-0] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2021] [Accepted: 11/29/2021] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND To improve the developmental competence of in vitro cultured oocytes, extensive literature focused on maturation rate improvement with different additives in culture medium, while studies investigating the maturation dynamics of oocytes during in vitro maturation (IVM) and the influencing factors on oocyte viability are scarce. METHODS The study involved a retrospective observation by time-lapse monitoring of the IVM process of 157 donated GV oocytes from 59 infertile couples receiving ICSI in 2019, in Tongji Hospital, Wuhan, China. The GV oocytes derived from controlled ovarian hyperstimulation (COH) cycles underwent rescue IVM (R-IVM), and the maturation dynamics, including GVBD time (GV-MI), time from GVBD to maturation (MI-MII), maturation time (GV-MII), and MII arrest duration (MII-ICSI), were recorded by time-lapse monitoring. The matured oocytes were inseminated at different MII arrest points and subsequent embryo developments were assessed. The effects of baseline clinical characteristics, oocyte diameters, and maturation dynamics on the developmental competence of the oocytes were also analyzed. RESULTS Totally, 157 GV oocytes were collected. GVBD happened in 111 oocytes, with a median GV-MI duration of 3.7 h. The median MI-MII duration was 15.6 h and the median GV-MII duration was 19.5 h. The maturation rate reached 56.7% at 24 h and 66.9% at 48 h, and the clinical factors, including patient age, FSH level, AMH level, ovarian stimulation protocol, and serum estradiol and progesterone levels on hCG trigger day, showed no effects on the 24-h maturation rate. The normal fertilization rate of oocytes resuming meiosis within 8 h and matured within 24 h was significantly higher than that of oocytes resuming meiosis after 8 h and matured after 24 h. Furthermore, among those oocytes matured within 24 h, the high-quality embryo formation rate of oocytes resuming meiosis within 4.5 h and matured within 19 h was significantly higher. All stated time was measured from the start point of IVM. Additionally, for oocytes from patients with serum progesterone levels less than 1 ng/ml on hCG trigger day, the high-quality embryo formation rate was significantly increased. CONCLUSION R-IVM technology could increase the available embryos for patients in routine COH cycles, but excessive culture beyond 24 h is not recommended. GV-MI duration of the oocyte, recorded by time-lapse system, and serum progesterone levels of patients on hCG trigger day can significantly affect the developmental potential of the IVM oocytes.

Live birth rate with double ovarian stimulation is superior to follicular phase ovarian stimulation per started cycle in poor ovarian responders. J Obstet Gynaecol Res 2021; 47:2705-2712. [PMID: 34062624 DOI: 10.1111/jog.14871] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2021] [Revised: 04/12/2021] [Accepted: 05/16/2021] [Indexed: 11/29/2022]
Abstract
AIM To compare the outcome of double ovarian stimulation (DOS) with follicular phase ovarian stimulation (FPS) per started cycle in poor ovarian responders (PORs). METHODS A total of 204 PORs who underwent ovulation induction for in vitro fertilization, cryopreservation of all embryos available, and frozen embryo transfer cycle were retrospectively analyzed. Of those, 146 received single FPS, and 58 received DOS. All viable embryos were cryopreserved and subsequently transferred within 1-6 months. RESULTS The number of oocytes collected and the number of mature oocytes per started cycle were higher in the DOS group compared to the FPS group (6.0 ± 1.9 vs. 2.8 ± 1.3 and 4.3 ± 1.3 vs. 2.2 ± 1.2, respectively, p = 0.001). Clinical pregnancy rate and live birth rate per started cycle were also significantly higher in the DOS group than the FPS group (41.4% vs. 16.4% and 36.2% vs. 15.1%, respectively, p < 0.001). The cancellation rate of embryo transfer due to no viable embryo was significantly lower in the DOS group (10.3%) than the FPS group (40.4%) (p = 0.001). In the DOS group, numbers of oocytes (3.2 ± 1.2 vs. 2.7 ± 1.1, p = 0.006), MII oocytes (2.6 ± 1.0 vs. 2.1 ± 0.8, p = 0.001), and cryopreserved blastocysts (1.5 ± 0.8 vs. 1.1 ± 0.7, p = 0.002) were significantly higher in the luteal ovarian stimulation compared to follicular ovarian stimulation. CONCLUSIONS Live birth per started cycle with DOS is superior to FPS in PORs. Luteal phase stimulation contributes to improving pregnancy rates in these patients.
