Abstract
PROBLEM Previously, we reported the clinical efficacy of tacrolimus in women with repeated implantation failures (RIF) of immune etiologies. Safety of tacrolimus in pregnant women has been reported in women with organ transplantations. However, the safety of tacrolimus for women with RIF undergoing assisted reproductive technology cycles and their babies has not been reported prior. METHOD OF STUDY This study is a prospective observational study of 109 women with RIF or recurrent pregnancy losses (RPL) who showed elevated peripheral blood Th1/Th2 (CD4+ IFN-γ+ /CD4+ IL-4+ ) cell ratios (≥10.3). All received tacrolimus before and during pregnancy (1-4 mg/d) and delivered a live-born infant(s). Blood concentrations of tacrolimus were measured. Neuromotor development of the babies was also evaluated. RESULTS Total 113 babies were born from 109 women, including four twin pregnancies. Nine pregnancies including four twins were delivered prematurely (8.3%). Two of 109 women showed obstetric complications, such as hypertensive disorder of pregnancy, and only one baby (0.9%) had a congenital abnormality. There were no differences in babies' birthweight, placental weight, and lymphocyte proportion (%) of the umbilical cord among the women with different tacrolimus dosing. Tacrolimus was detected in the maternal plasma, and its concentration did not significantly fluctuate during pregnancy while on daily administration regimen. Neuromotor development of the babies exposed to tacrolimus in utero was comparable with that of babies from the general population. CONCLUSION According to our data, tacrolimus treatment for women with RIF and RPL was not associated with obstetrical and perinatal complications. A large size study is needed to confirm this finding.

Abstract
A Rho-incompatible pregnancy induces anemia in the fetus and can ultimately lead to fetal hydrops and intrauterine fetal death. A patient who had experienced recurrent implantation failures following a first successful delivery finally succeeded in achieving a second pregnancy via the use of tacrolimus. The second pregnancy was Rho-incompatible. During the course of the pregnancy, the treatment with tacrolimus was continued because the patient's T helper type 1 (Th1) cell population remained at a high level following the achievement of pregnancy. The dose was increased during pregnancy because of the elevated Th1 cell count at 28-week gestation. Tacrolimus maintains a stable state of pregnancy while simultaneously suppressing the production of anti-D antibodies. Using tacrolimus, we succeeded in resolving the infertility and inhibition of antibody production in this case of an alloimmunized pregnancy.

Abstract
BACKGROUND An ever-increasing number of women in our country with advanced maternal age are choosing to achieve pregnancy. This means effective strategies are needed for infertile patients. Questions arise, however, concerning the need for ovarian stimulation, and, if so, whether intracytoplasmic sperm injection (ICSI) is better than conventional insemination for those women who may have only one mature oocyte. METHODS We evaluated our data to answer these questions. Herein, we also introduce our strategy for patients who show unsynchronized follicular growth. MAIN FINDINGS Ovarian stimulation in ART treatment for patients with advanced maternal age has resulted in the achievement of higher pregnancy rates, and therefore, this form of stimulation is often selected. Based on our data, ICSI as an insemination procedure has not improved clinical pregnancy rates compared with conventional insemination and has actually decreased the clinical pregnancy rates. CONCLUSION In this article, we reviewed and compared the protocols and strategies that are available to increase the number of developed embryos for the patients with advanced maternal age. We hope that this review will be helpful for both patients and clinicians.

Abstract
Vitamin D (VD) deficiency is associated with reproductive failure. However, the relationship between VD and maternal immunity remains unclear. We investigated the clinical efficacy of VD in maternal T-helper (Th) cytokines in 276 infertile women and examined for Th1 and Th2 cells based on the deficient, insufficient, and sufficient serum 25-hydroxyvitamin D3 (25[OH]VD) levels (<12, 12–30, and >30 ng/mL, respectively). Most infertile women had a low-level of VD (87.3%). Immunological tests of pre-/post-VD supplementation were performed in patients who were deficient and insufficient in VD. Of 23 patients, 11 (47.8%) exhibited sufficient VD levels after supplementation. Th1/Th2 cell ratio in patients with insufficient VD was significantly decreased after supplementation (p = 0.004). After supplementation, serum 25(OH)VD levels of the patients: 11 in the sufficient group showed significant decreases in Th1 cell level and Th1/Th2 cell ratio (p = 0.032 and 0.010, respectively), whereas no significant differences in Th1/Th2 cell ratio were recognized in the insufficient group. Furthermore, mid-luteal endometrial biopsies (n = 18) were processed for primary cultures and measured interferon [IFN]-γ and interleukin [IL]-4 in condition media. Decidualizing cultures with 1,25-dihydroxvitamin D3 (1,25[OH]2VD) decreased IFN-γ. Sufficient VD supplementation in women with insufficient VD may optimize maternal T-helper cytokines during pregnancy via rebalancing the Th1/Th2 cell ratio.

Abstract
Purpose To evaluate the efficacy and safety of self-injections of the prefilled recombinant human chorionic gonadotropin (r-hCG) in a syringe in assisted reproductive technology (ART) treatment for the maturation trigger (MT), as compared to self-injections of conventional hCG and intranasal administration of gonadotropin-releasing hormone agonist (GnRH-a). Methods Between January and April, 2017, 396 patients who underwent oocyte retrieval were recruited. Of these, 396 patients were classified into three groups, according to the types of MT: (1) the urinary human chorionic gonadotropin (u-hCG) group that consisted of patients who had a self-injection of u-hCG (n = 127); (2) the GnRH-a group that received nasal administration of GnRH-a (n = 159); and (3) the r-hCG group that had a self-injection of r-hCG (n = 110). Several ART outcomes were evaluated. Results The mature oocyte retrieval rate was not different between the u-hCG, r-hCG, and GnRH-a groups and the fertilization and cleavage rates were similar between the three groups. The clinical pregnancy rates did not significantly differ between the GnRH-a group and the u-hCG group; however, it was significantly lower in the GnRH-a group, compared to the r-hCG group. No difference was observed in the incidence of moderate or more severe ovarian hyperstimulation syndrome among the three groups. Conclusion The self-injection of the prefilled r-hCG is a favorable MT for ART patients.

Abstract
The epigenetic status of the genome changes dynamically from fertilization to implantation. In addition, the physiological environment during the process of gametogenesis, including parental age, may affect the epigenome of the embryo after fertilization. It is important to clarify the influence of parental age on gene expression in the embryo in terms of transgenerational epigenetics to improve the techniques currently used in assisted reproductive medicine. Here, we performed single-embryo RNA-seq analysis on human blastocysts fertilized by intracytoplasmic sperm injection, including from relatively elderly mothers, to elucidate the effects of parental age on the embryonic gene expression profile. We identified a number of genes in which the expression levels were decreased with increasing maternal age. Among these genes, several are considered to be important for meiotic chromosomal segregation, such as PTTG1, AURKC, SMC1B and MEIKIN. Furthermore, the expression levels of certain genes critical for autophagy and embryonic growth, specifically GABARAPL1 and GABARAPL3, were negatively correlated with advanced paternal age. In addition, levels of transcripts derived from major satellite repeats also decreased as the maternal age increased. These results suggest that epigenetic modifications of the oocyte genome may change with parental age and be transmitted to the next generation.

Abstract
Aim An immune etiology for idiopathic recurrent miscarriage is an important issue because a fetus is allogenetically different from the mother. Type 1 T helper (Th1) and Type 2 (Th2) cells have important functions in immune responses and there is a general agreement that pregnancy is associated with Th2 cell dominance. The purpose of this case report is to establish the effectiveness of an immunosuppressive treatment for a patient who had 11 consecutive miscarriages despite several treatments, such as anticoagulation, that showed elevated Th1/Th2 cell ratios. Methods This patient visited our clinic following 11 consecutive miscarriages between 2009 and 2014 that occurred between 5 and 8 weeks’ gestation. The Th1/Th2 cell ratio was evaluated after the 12th conception and she received an immunosuppressive treatment (tacrolimus; 1 mg/d). Results The Th1/Th2 cell ratio was elevated after the 12th conception, but the patient miscarried, with a normal karyotype of chorionic villi despite the immunosuppressive treatment. After the 13th conception, she began receiving treatment with 2 mg/d of tacrolimus at 4 weeks’ gestation, which was continued until delivery. Conclusion For recurrent miscarriage cases that show an elevated Th1/Th2 cell ratio after achieving pregnancy, immunosuppressive treatment with tacrolimus could be effective.

Abstract
PROBLEM We aim to investigate whether the peripheral blood T helper (Th) 1 cell level could predict pregnancy outcome in patients who have experienced repeated implantation failure (RIF, three or more) after ART cycles. METHOD OF STUDY This is a prospective cohort study of total 124 women with RIF who showed elevated Th1/Th2 (CD4+ IFN-γ+ /CD4+ IL-4+ ) cell ratios (≥10.3) and received tacrolimus at Sugiyama Clinic between November 2011 and July 2016. Patients were divided into three groups as per Th1 cell levels: Th1 level of <22.8 as Low; 22.8 to <28.8 as Middle, and 28.8 or greater as High group. The study patients received daily dose of tacrolimus 1-3 mg based on initial Th1/Th2 cell ratio. RESULTS The clinical pregnancy rates of Low, Middle, and High groups were 48.8%, 43.9%, and 33.3%, respectively (P=NS), with tacrolimus treatment. The ongoing pregnancy/delivery rate of Low group (46.3%) was significantly higher than that of High group (21.4%, P<.05). Middle group (34.3%) had higher success rate than High group, albeit without statistical significant. CONCLUSION We confirm our previous report that Th1/Th2 ratio can predict ART outcomes in patients with RIF and immunosuppressant treatment with tacrolimus, and peripheral blood Th1 cell levels were negatively correlated with pregnancy outcome.

Abstract
PURPOSE Follicular fluid (FF) might reflect the environment during follicle and oocyte growth, and an evaluation of oxidative stress in the FF might be useful in predicting oocyte quality. In order to measure the oxidative stress (OS) in the FF from a single follicle of patients with endometrioma (EM), we evaluated whether an EM might affect the environment of follicular growth. METHODS Between December 2011 and July 2013, 26 patients with a unilateral EM (EM group) and 29 without EM (control group) were enrolled in this study. The FF was obtained during the first puncture of follicular aspiration, and was stored at -30 °C until it was assayed. A Free Radical Elective Evaluator (WISMERLL, USA) was used to perform d-ROM and BAP tests to measure oxidative stress (U.CARR) and antioxidant power (μmol/L). RESULTS The d-ROM values in the EMC and control groups were 328.7 ± 97.8 and 414.9 ± 84.2, respectively, and the BAP values for the two groups were 2474.3 ± 432.0 and 2552.8 ± 435.58, respectively. These values were similar between the two groups (mean ± SD). The number of patients with a modified BAP/d-ROM ratio of <1.0 in the EM group was similar to that for the control group at 16 and 15, respectively (61.5 and 51.7 %). CONCLUSIONS The oxidative stress and antioxidant potential in the FF of the patients with unilateral EM showed values similar to those without an EM. Therefore, we concluded that EMs do not affect the environment for follicle growth during ART treatment.

Abstract
BACKGROUND The purpose of this study was to evaluate the effect of needle type on pain and bleeding during oocyte pick-up (OPU). METHODS From May through November 2013, patients undergoing OPU from a single follicle without any analgesic treatment were including this study. Eligible patients (n=75) were randomized 1:1 to undergo the procedure with either a reduced needle (17 gauge body, 20 gauge tip; RN group) or a standard needle (19 gauge; SN group). Overall pain was assessed by patients using a visual analogue scale (VAS), and vaginal bleeding after the procedure was recorded. Fisher exact, t-test or Wilcoxon test were used, and p<0.05 was considered to be statistically significant. RESULTS The percentage of mature oocytes was 86.5% in the RN group and 91.7% in the SN group. Pain during OPU was significantly lower in the RN group than in the SN group (mean VAS score±SD: 3.2±2.0 cm vs. 4.9±2.2 cm, p<0.01; mean±SD). The frequency of vaginal bleeding was also significantly lower in the SN group (26.3% vs. 48.6%; p<0.05). The frequency of bleeding in the RN group was also significantly lower than that in the SN group (26.3% vs. 48.6%; p<0.05). No significant differences were found between the two groups with regard to fertilization and pregnancy rates. CONCLUSION The newly designed needle significantly reduced pain and vaginal bleeding associated with single-follicle OPU in patients receiving no analgesic treatment, in comparison with a standard needle. The RN had no adverse effect on the quality of retrieved oocytes.

Abstract
Purpose To investigate whether clomiphene citrate (CC) affects uterine receptivity or not, we evaluated pregnancy rates (PR) during the hormone replacement cycle (HRC) according to the period between the last day of CC administration and the day of embryo transfer (ET). Methods From March 2008 through March 2010, a total of 378 treatment cycles among 378 patients who received CC and had to avoid fresh ET due to a thin uterine endometrium were recruited. All patients underwent thawed ET using HRC. PRs were evaluated according to the period between the last CC treatment and the day of ET. Results PR for the groups in which the period between the last CC treatment and the day of ET increased to more than 91 days were significantly higher than that for group in which the period was less than 90 days (p < 0.05). Conclusions A lower PR was shown by the patients who underwent thawed ET in the HRC within 90 days after their last CC treatment, which shows that CC affects the receptivity of the uterine endometrium.

Abstract
PURPOSE Zygote intrafallopian transfer (ZIFT) is an effective option for patients who have experienced repeated implantation failures (RIF) in assisted reproductive technology (ART) treatment. However, advance planning for the day of the operation can be problematic. Using a hormone replacement cycle (HRC) makes it possible to plan for the day of ZIFT. In the present study, we evaluated whether HRC-ZIFT is useful for RIF patients who have experienced difficulties obtaining morphologically good embryos in vitro. METHODS A total of 55 patients with a history of five or more unsuccessful transfers received HRC-ZIFT between June 2008 and June 2013. The oocyte pick-ups were performed and the oocytes showing two pronuclei (2PN) were cryopreserved. After receiving more than five 2PN oocytes, the operation day was scheduled in advance, and as a consequence, a HRC was started and ZIFT was performed. The clinical outcomes were evaluated. RESULTS The average age of the patients was 39.3 years, and the previous OPU and ET attempts numbered 7.5 and 6.9, respectively. The number of previously transferred embryos was 11.8, and the number of morphologically good embryos (MGEs) was only 1.2. The number of transferred 2PN oocytes was 6.7, and the subsequent pregnancy rate was 23.6 %. No ectopic or multiple pregnancies were observed, but there were 6 cases of miscarriage. CONCLUSION Among RIF patients, in particular those who have difficulty obtaining MGEs in vitro, ZIFT might be a useful option. The HRC allows patients and medical staff to plan for the operation day in advance.

Abstract
PURPOSE The purpose of this study was to investigate how many oocytes are needed to achieve an adequate pregnancy rate per 1 oocyte retrieval cycle in mild ovarian stimulation. METHODS This protocol consisted of clomiphene citrate and recombinant-follicle-stimulating hormone injection without a gonadotropin-releasing hormone-antagonist. From January 2009 through December 2010, there were 1,227 women who underwent assisted reproductive technologies treatment with mild stimulation at the Sugiyama Clinic. The overall pregnancy rate per single oocyte retrieval cycle was evaluated using both fresh and cryopreserved-and-thawed embryos according to the retrieved oocyte number. RESULTS According to the retrieved oocyte number, a total of 1,227 cycles were divided into 4 groups: group A (the oocyte number <4; 433 cycles), group B (the oocyte number = 4, 5; 317 cycles), group C (the oocyte number = 6, 7; 206 cycles), and group D (the oocyte number ≥8; 271 cycles). The overall pregnancy rates for groups A, B, C, and D were 22.2, 42.9, 52.4, and 56.0 %, respectively, the rates for groups C and D were significantly higher than that for group A (p < 0.01). CONCLUSIONS The optimal number of retrieved oocytes proved to be between 6 and 7 for the patients who received our milder stimulation protocol and experienced no reduction in their overall pregnancy rate.

Abstract
AIM The aim of this study was to observe the insides of the fallopian tubes of patients with unilateral or bilateral endometriomas by using salpingoscopy and evaluate the inner cavity of the fallopian tubes according to our original scoring system. MATERIAL AND METHODS From April 2008 through December 2010, patients with unilateral or bilateral endometriomas were recruited (n = 157, endometrioma group). All patients underwent laparoscopic ovarian cystectomy and salpingoscopy. Using salpingoscopy, we observed the tubal lumen and calculated a fallopian tube score (F score) paying attention to the following six results: adhesions, loss of mucosal folds, rounded edges of mucosal folds, debris, foreign bodies, and abnormal vessels. The F scores were compared with those of the unexplained infertility patients who received those same procedures during the same period (n = 235; control group). RESULTS Slightly more than three-quarters (75.9%) of the patients in the endometrioma group received F scores of 0, and this percentage was significantly higher than that for the control group (139/235 = 59.1%, P < 0.05). The pregnancy rate after conventional treatment for the endometrioma group was 21.7%, and all pregnant patients had achieved an F score of less than 2. CONCLUSION It is highly possible that infertility patients with ovarian endometriomas are more likely to have intact fallopian tubes, by comparison with infertility patients who do not have ovarian endometriomas.

Abstract
PURPOSE The purpose was to establish a mild ovarian stimulation protocol that would help assisted reproductive technology (ART) units to avoid scheduling on weekends. METHODS This protocol directed patients to take 50 mg/day of clomiphene citrate between days 3 and 7 of the menstrual cycle: 225 IU of recombinant follicle-stimulating hormone (rec-FSH) were administered on days 3, 5 and 7; human chorionic gonadotropin (hCG) was administered on day 9; and, oocyte pick-up (OPU) was planned for day 11. From October 2008 through October 2009, 514 women underwent ART treatment with mild stimulation at the Sugiyama Clinic, and we evaluated whether OPU was accomplished on the planned day. RESULTS Of all the treatment cycles, 419 (81.5%) underwent OPU on day 11 (scheduled group). Additional rec-FSH administration was needed in 83 cycles, in which case OPU was performed on day 12 or later. In 12 cycles, OPU was canceled. The unscheduled group (n = 95) consisted of delayed OPU cycles and canceled cycles. Of all treatment cycles, 332 cycles in the scheduled group and 68 cycles in the unscheduled group underwent embryo transfer, with 81 and 16, respectively, resulting in pregnancies. CONCLUSIONS Using this protocol, OPU was performed on the scheduled day in about 80% of the cycles. Most weekend scheduling of OPU can be avoided using this mild stimulation.

Abstract
BACKGROUND AND STUDY AIMS Conventional colonoscopy can result in unnecessary biopsy or endoscopic resection due to its inability to distinguish adenomas from hyperplastic polyps. This study therefore evaluated the efficacy of high-resolution endoscopy (HRE), autofluorescence imaging (AFI), and narrow-band imaging (NBI) in discriminating colon adenoma from hyperplastic polyps. PATIENTS AND METHODS This was a prospective multicenter study in patients undergoing AFI and NBI examinations. HRE, AFI, and NBI images were classified into two groups based on morphological characteristics, the predominant color intensities, and the visibility of meshed capillary vessels, respectively. Each of the endoscopic photographs were independently evaluated by a single endoscopist. The images were then assessed by three specialists and three residents, the latter having performed < 500 colonoscopies and < 30 NBI and AFI examinations. Diagnostic test statistics were calculated to compare the accuracy in differentiating colon adenoma from hyperplastic polyps for each method. RESULTS A total of 183 patients were enrolled in the study and 339 adenomas and 85 hyperplastic polyps were identified. AFI and NBI could distinguish adenoma from hyperplastic polyps with an accuracy of 84.9 % and 88.4 %, respectively, whereas HRE exhibited an accuracy of 75.9 %. In the 358 lesions in which the AFI diagnosis was consistent with that of NBI, the accuracy, sensitivity, and specificity were high, at 91.9 %, 92.7 %, and 92.9 %, respectively. During the study comparing specialists and residents, AFI and NBI dramatically improved the diagnostic accuracy of residents from 69.1 % to 86.1 % and 84.7 %, respectively. CONCLUSIONS Both AFI and NBI are considered to be feasible tools that can discriminate colon adenoma from hyperplastic polyps, and their use may be particularly beneficial for less-experienced endoscopists.
