Intrauterine Infusion and Hysteroscopic Injection of Autologous Platelet-Rich Plasma for Patients with a Persistent Thin Endometrium: A Prospective Case-Control Study.

Objectives: To evaluate the effect of intrauterine infusion and hysteroscopic injection of autologous platelet-rich plasma (PRP) in patients with a persistent thin endometrium (EM) undergoing euploid frozen embryo transfer (EFET) cycles. Methods: This prospective case-control study enrolled 116 infertile women with thin EM (<7 mm) who underwent hormone replacement therapy (HRT) for EFET. These women had experienced at least one previous unsuccessful EFET cycle, which either resulted in the cancellation of the cycle or failure of pregnancy. A total of 55 women received an intrauterine infusion of PRP before FET, 38 received a hysteroscopic injection of PRP, and 23 received standard HRT treatment without PRP (control group). Only euploid embryos were transferred in these cycles. The primary outcomes were the implantation rate (IR) and clinical pregnancy rate (CPR) after EFET. Results: After receiving intrauterine infusion and hysteroscopic injection of PRP, 78.2% and 55.3% of patients, respectively, showed an EM thickness exceeding 7 mm, followed by embryo transfer. The hysteroscopic injection group demonstrated significantly higher IR (52%), a higher trend of CPR (52%), and a higher live birth rate (38%) than the control group (18%, 22%, and 4%). Conclusions: Intrauterine infusion and hysteroscopic injection of autologous PRP may be effective methods to increase EM thickness in HRT cycles. According to our results, both methods could increase EM thickness, while hysteroscopic injection appeared to provide more significant assistance in increasing IR, CPR, and live birth rate after EFET in patients with persistent thin EM.

Associations between the artificial intelligence scoring system and live birth outcomes in preimplantation genetic testing for aneuploidy cycles.

BACKGROUND: Several studies have demonstrated that iDAScore is more accurate in predicting pregnancy outcomes in cycles without preimplantation genetic testing for aneuploidy (PGT-A) compared to KIDScore and the Gardner criteria. However, the effectiveness of iDAScore in cycles with PGT-A has not been thoroughly investigated. Therefore, this study aims to assess the association between artificial intelligence (AI)-based iDAScore (version 1.0) and pregnancy outcomes in single-embryo transfer (SET) cycles with PGT-A. METHODS: This retrospective study was approved by the Institutional Review Board of Chung Sun Medical University, Taichung, Taiwan. Patients undergoing SET cycles (n = 482) following PGT-A at a single reproductive center between January 2017 and June 2021. The blastocyst morphology and morphokinetics of all embryos were evaluated using a time-lapse system. The blastocysts were ranked based on the scores generated by iDAScore, which were defined as AI scores, or by KIDScore D5 (version 3.2) following the manufacturer's protocols. A single blastocyst without aneuploidy was transferred after examining the embryonic ploidy status using a next-generation sequencing-based PGT-A platform. Logistic regression analysis with generalized estimating equations was conducted to assess whether AI scores are associated with the probability of live birth (LB) while considering confounding factors. RESULTS: Logistic regression analysis revealed that AI score was significantly associated with LB probability (adjusted odds ratio [OR] = 2.037, 95% confidence interval [CI]: 1.632-2.542) when pulsatility index (PI) level and types of chromosomal abnormalities were controlled. Blastocysts were divided into quartiles in accordance with their AI score (group 1: 3.0-7.8; group 2: 7.9-8.6; group 3: 8.7-8.9; and group 4: 9.0-9.5). Group 1 had a lower LB rate (34.6% vs. 59.8-72.3%) and a higher rate of pregnancy loss (26% vs. 4.7-8.9%) compared with the other groups (p < 0.05). The receiver operating characteristic curve analysis verified that the iDAScore had a significant but limited ability to predict LB (area under the curve [AUC] = 0.64); this ability was significantly weaker than that of the combination of iDAScore, type of chromosomal abnormalities, and PI level (AUC = 0.67). In the comparison of the LB groups with the non-LB groups, the AI scores were significantly lower in the non-LB groups, both for euploid (median: 8.6 vs. 8.8) and mosaic (median: 8.0 vs. 8.6) SETs. CONCLUSIONS: Although its predictive ability can be further enhanced, the AI score was significantly associated with LB probability in SET cycles. Euploid or mosaic blastocysts with low AI scores (≤ 7.8) were associated with a lower LB rate, indicating the potential of this annotation-free AI system as a decision-support tool for deselecting embryos with poor pregnancy outcomes following PGT-A.

Significantly shortened telomere length and altered androgen receptor level in cumulus cells from women with polycystic ovary syndrome.

OBJECTIVE: The aim of this study was to investigate the correlation between hormone receptor levels and telomere length (TL) in infertile women with and without polycystic ovary syndrome (PCOS). MATERIALS AND METHODS: This prospective cohort study recruited a total of 431 cumulus oocyte complex (COC) from 88 infertile women between July 2012 and June 2014. The participants were divided into three groups: young age (<38 years, n = 42 and 227 COC), advanced age (≥38 years, n = 33 and 107 COC) and PCOS patients (n = 13 and 97 COC). Cumulus cells were collected from individual follicle during oocyte pick-up, and the mRNA levels of hormone receptors and TL were measured using real-time PCR. RESULTS: The cumulus cells of PCOS patients demonstrated lower mRNA levels of LH receptor (75.57 ± 138.10 vs. 171.07 ± 317.68; p < 0.01) and androgen receptor (1.13 ± 1.52 vs. 4.08 ± 9.57; p < 0.01), as well as a shorter TL (2.39 ± 2.58 vs. 3.96 ± 4.72; p < 0.01) compared to those of the young age group. In the young age group, only androgen receptor mRNA level showed a significant association with TL (rho = 0.148, p = 0.026), while FSH receptor mRNA level was the only factor associated with TL (rho = 0.247, p = 0.015) in PCOS patients. For advanced-aged patients, no significant relationship was observed between hormone receptor mRNA levels and TL. Alternative splicing of androgen receptors was identified in some PCOS patients but not in young age controls. CONCLUSION: The findings suggest that the androgen receptor level and function may be altered in the cumulus cells of PCOS patients, leading to a shorter TL in cumulus cells in PCOS patients.

Assessment of Telomere Length and Mitochondrial DNA Copy Number in Granulosa Cells as Predictors of Aneuploidy Rate in Young Patients.

Background: To identify the correlation among female age, cellular aging markers, and aneuploidy rate in in vitro fertilization (IVF) and the preimplantation genetic test for aneuploidy (PGT-A) cycles. Methods: This is a prospective cohort study recruiting 110 infertile women between August 2017 and July 2018. They were divided into young-age (<38 years, n = 60) and advanced-age (≥38 years, n = 50) groups. Peripheral leukocytes were assessed, and the granulosa cells were pooled during oocyte pickup. Mitochondrial DNA (mtDNA) copy number and telomere length (TL) were measured using real-time polymerase chain reaction. PGT-A was performed on the NGS platform. Results: mtDNA copy number and TL were positively correlated in both leukocytes (rho = 0.477, p < 0.001) and granulosa cells (rho = 0.361, p < 0.001), but the two parameters in leukocytes were not correlated with those in granulosa cells. In the young-age group, TL in the granulosa cells was the only factor correlated with the aneuploidy rate (rho = −0.283, p = 0.044), whereas in the advanced-age group, age was the main factor (rho = 0.358, p = 0.018). Conclusions: TL in the granulosa cells was negatively correlated with the aneuploidy rate in the young-age group, supporting the application of PGT-A in younger women.

The debated role of bariatric surgery in improving in-vitro fertilization outcomes in morbidly-obese infertile women-a case report and brief overview.

OBJECTIVE: Obesity has a negative impact on in-vitro fertilization (IVF) outcomes, and obese women who plan IVF treatments are often encouraged to pursue weight reduction. Bariatric surgery is an effective strategy for the treatment of morbidly obese women. The current case report is to investigate the impact of bariatric surgery on IVF outcome in a morbidly obese woman with subfertility. CASE REPORT: A 37-year-old, morbidly obese woman with subfertility was indicated for IVF treatment. Due to her high body mass index (47.9 kg/m2), she was advised to lose weight; initial failure at conservative measures of weight loss prompted her to undergo bariatric surgery, combined with post-operative lifestyle change, prior to receiving IVF treatment. The woman successfully conceived at the second cycle and delivered twins by cesarean section smoothly at 36 + 3/7 weeks of gestation. Both twins have normal development up to two years of age. CONCLUSIONS: Weight reduction mediated by bariatric surgery in subfertile and morbidly obese women can be considered before IVF treatment.

Could PGT-A pick up true abnormalities that have clinical relevance? Retrospective analysis of 1043 embryos.

OBJECTIVE: To determine whether preimplantation genetic testing for aneuploidy (PGT-A) could pick up true abnormalities that have clinical relevance. MATERIALS AND METHODS: This was a retrospective cohort study of patients who underwent in vitro fertilization with PGT-A from 2015 to 2017. We evaluated the associations of aneuploidy and mosaicism with maternal age, the chromosome abnormalities present in individual chromosomes, and the effect of embryo sex on the proportion of each type of error in the four chromosomes most frequently affected. RESULT(S): A total of 1043 embryos from 255 patients (mean maternal age = 39 ± 4 years) were included in the initial analysis. Of these, 36% (377/1043) were euploid, 47% (487/1043) were aneuploid, 13% (140/1043) contained mosaicism, and 4% (39/1043) gave no result. We excluded the 39 embryos with no result; thus, 1004 embryos were included in the analysis. Increased aneuploidy was associated with increased maternal age, but the rate of embryo mosaicism was not. A combined analysis of aneuploidy with noncomplex abnormalities and mosaicism showed that chromosomes 22, 21, 16, and 15 were the most frequently involved. Chromosome 22 showed the highest proportion of mosaicism and chromosome 15 showed the highest proportion of aneuploidy. When we included embryo sex in the analysis, embryo sex was associated with these chromosome errors in the most susceptible chromosome, 22. CONCLUSION(S): PGT-A showed that chromosomes 22, 21, 16, and 15 were the most frequently involved among common chromosome abnormalities, comparable with those of published data analyzed from spontaneous abortion. This result suggested that PGT-A could pick up abnormalities that have clinical relevance to spontaneous abortion. Moreover, we identified a role of embryo sex in these chromosomal errors on chromosome 22.

Evaluation of adenomyosis after gonadotrophin-releasing hormone agonist therapy using ultrasound post-processing imaging: a pilot study.

OBJECTIVE: We explored a method for the quantitative sonographic analysis of myometrial texture using computer-aided image analysis software to assess outcomes following treatment with gonadotrophin-releasing hormone (GnRH) agonist for adenomyosis in women with infertility. METHOD: Data for patients with ultrasound images of the myometrium obtained at Taipei Medical University Hospital from 1 September 2018 to 5 April 5 2019 were analyzed. Only 10 patients with 20 ultrasound images matched the eligibility criteria. The images were divided into pre-treatment (n = 10) and post-treatment images (n = 10) and quantitative grayscale histograms were obtained from the ultrasound images using publicly available ImageJ computer-aided image analysis software. We analyzed the differences between the pre- and post-treatment images using the Mann-Whitney test and compared the results with outcomes assessed by serum CA-125 levels. RESULTS: Image analysis of the grayscale histograms revealed significant differences between before and after treatment. The classification of the myometrium pre-treatment and post-treatment was similar using CA-125 and histogram grayscale analysis. CONCLUSION: Computer-aided image analysis of grayscale histograms of the myometrium obtained from ultrasound images is an alternative method for assessing myometrial conditions after GnRH agonist treatment in patients with adenomyosis.

Healthy live births after mosaic blastocyst transfers with the use of next-generation sequencing.

OBJECTIVE: To determine whether transfer of high-mosaicism (≥50%) embryos can result in healthy newborns. CASE REPORT: Two embryos resulting from controlled ovarian stimulation (COS) in Patient one, 41 years of age (y/o), underwent preimplantation genetic testing for aneuploidy (PGT-A), which demonstrated that one was mosaic (68%) and the other aneuploid; the mosaic embryo was transferred. Amniocentesis at 18 weeks of gestational age (GA) revealed a normal 46, XY karyotype. A phenotypically normal boy was delivered at 39 and 5/7 weeks of GA. For Patient two, 39 (y/o), nine embryos obtained after COS underwent PGT-A, indicating one euploid, four mosaic, and four aneuploid embryos. One euploid and one mosaic (50%) embryo were transferred, resulting in a twin pregnancy. Amniocentesis at 18 weeks of GA showed both fetuses had normal 46, XY karyotypes. Two phenotypically normal boys were delivered at 37 2/7 weeks of GA. CONCLUSION: Transfer of high-mosaicism embryos selected using current techniques can result in healthy euploid newborns. Amniocentesis suggested that mosaic embryos can be self-corrected before 18 weeks of GA.

A novel strategy of using corifollitropin alfa in the ultrashort gonadotropin-releasing hormone agonist (GnRHa) protocol in unselected patients: A patient-friendly alternative.

OBJECTIVE: To compare the outcomes of in vitro fertilization (IVF) and fresh embryo transfer (ET) using corifollitropin alfa in ultrashort gonadotropin-releasing hormone agonist (GnRHa) protocol and GnRH antagonist protocol. MATERIALS AND METHODS: A total of 245 unselected patients undergoing IVF/fresh ET were enrolled between January 1 and December 31, 2017, including 135 treated with ultrashort GnRHa protocol and 110 treated with antagonist protocol. The primary outcomes were number of total injections and outpatient department (OPD) visits before ovulation triggering. The secondary outcomes were the duration of stimulation, dosage of additional gonadotropin for ovarian hyperstimulation, rates of pregnancy, clinical pregnancy, live birth, ovarian response, and ovarian hyperstimulation syndrome (OHSS) rate. RESULTS: Patients treated with ultrashort GnRHa required less additional gonadotropin, fewer total injections, but had better ovarian responses, including more oocytes retrieved, more metaphase II oocytes, and more blastocysts than those treated with antagonist did. A premature LH surge occurred only in six patients treated with antagonist protocol. The rates of pregnancy (37.0% vs. 43.6%), clinical pregnancy (25.2% vs. 34.6%), and live birth (19.3% vs. 30.0%) did not differ significantly between the two groups. The OHSS rate was similar in the two groups. CONCLUSION: In unselected patients using corifollitropin alfa, the ultrashort GnRHa protocol needed lower dose of additional gonadotropin and fewer injections but produced similar pregnancy outcomes than antagonist protocol did, suggesting that the ultrashort GnRHa protocol could be an alternative.
