RESUMO
This review examines associations of nutrients and dietary preferences with recurrent pregnancy loss (RPL), miscarriage, and infertility. Research articles, reviews, and meta-analyses of RPL and infertility that focused on nutrition, meals, and lifestyle were reviewed, and associations of nutrients and dietary preferences with pregnancy are discussed in relation to recent research findings. Studies related to RPL were given the highest priority, followed by those dealing with miscarriage and infertility. Multivitamin supplements-even when lacking folic acid or vitamin A-reduced total fetal loss. High-dose folic acid supplementation before conception reduced the risk of miscarriage and stillbirth. A meta-analysis revealed a strong association of vitamin D deficiency/insufficiency with miscarriage. Another meta-analysis revealed that seafood and dairy products reduced the risk of miscarriage, whereas a caffeine intake of 300 mg/day or more was associated with miscarriage. A balanced diet that included nutrients with antioxidant properties helped prevent miscarriage, whereas a diet that included processed foods and nutrients with proinflammatory effects increased the risk of miscarriage. Associations of nutrients with RPL warrant further research.

Twelve years after the first edition of The Guideline for Gynecological Practice, which was jointly edited by The Japan Society of Obstetrics and Gynecology and The Japan Association of Obstetricians and Gynecologists, the 5th Revised Edition was published in 2023. The 2023 Guidelines includes 5 additional clinical questions (CQs), which brings the total to 103 CQ (12 on infectious disease, 30 on oncology and benign tumors, 29 on endocrinology and infertility and 32 on healthcare for women). Currently, a consensus has been reached on the Guidelines, and therefore, the objective of this report is to present the general policies regarding diagnostic and treatment methods used in standard gynecological outpatient care that are considered appropriate. At the end of each answer, the corresponding Recommendation Level (A, B, C) is indicated.

Purpose: The Japan Society of Obstetrics and Gynecology (JSOG) registry gathers comprehensive data from registered assisted reproductive technology (ART) facilities in Japan. Herein, we report 2021 ART cycle characteristics and outcomes. Methods: Descriptive statistics were used to summarize and analyze 2021 data. Results: In 2021, 625 ART facilities participated in the registry; 27 facilities did not conduct ART cycles and 598 registered treatment cycles. In total, 498 140 cycles were registered, and there were 69 797 neonates (increases of 10.7% and 15.5%, respectively, from the previous year). The number of freeze-all in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) cycles decreased in 2021; the number of neonates born was 2268 for IVF-embryo transfer (ET) cycles and 2850 for ICSI cycles. Frozen-thawed ET (FET) cycles increased markedly from 2020 (11.2% increase). In 2021, 239 428 FET cycles were conducted, resulting in 87 174 pregnancies and 64 679 neonates. For fresh transfers, the total single ET, singleton pregnancy rate, and singleton live birth rates were 82.7%, 97.0%, and 97.3%; for FET, these rates were 84.9%, 96.9%, and 97.1%. Conclusions: The 2021 Japanese ART registry analysis showed marked increases in both total treatment cycles and live births from the previous year.
RESUMO
This study aimed to elucidate the etiologies of and risk factors for recurrent pregnancy loss (RPL) according to fertile ability, focusing on the differences between superfertile and subfertile patients. This retrospective observational study included 828 women with RPL between July 2017 and February 2020. Patients were divided into three groups based on time to pregnancy (TTP): superfertile (SUP) (TTP ≤3 months for all previous pregnancies), subfertile (SUB) (previous TTP ≥12 months and use of assisted reproductive technology [ART]), and Normal (N) (TTP >3 or <12 months without ART). All patients were assessed for uterine anatomy, antiphospholipid antibodies (APAs), thyroid function, and thrombophilia. Of the 828 patients, 22%, 44%, and 34% were assigned to the SUP, SUB, and N groups, respectively. The mean ages were 33.9, 38.2, and 35.9 years in the SUP, SUB, and N groups, respectively, revealing a significant difference (P < 0.001). The anti-CL ß2GPI antibody positivity rate was significantly higher in the SUP group (4.6%) than in the N group (0.8%; P = 0.016). The prevalence of APA positivity was lowest in the N group. Overall, the clinical characteristics and etiologies of RPL associated with superfertility and subfertility were strikingly similar, with comparable positivity rates after adjusting for maternal age. Further investigation including chromosomal analysis of products of conception is needed to elucidate the clinical impact of differences in fertility on patients with RPL.

Preterm birth (PTB) is the leading cause of neonatal mortality, and reducing the PTB rate is one of the most critical issues in perinatal medicine. Cervical insufficiency (CI), a major cause of PTB, is characterised by premature cervical ripening in the second trimester, followed by recurrent pregnancy loss. Although multiple clinical trials have suggested that progesterone inhibits cervical ripening, no studies have focused on progesterone-induced molecular signalling in CI. Here, we established a primary culture system for human uterine cervical fibroblasts using a sample of patients with refractory innate CI who underwent transabdominal cervical cerclage and patients with low Bishop scores who underwent elective caesarean section as controls. RNA sequencing showed that the progesterone response observed in the control group was impaired in the CI group. This was consistent with the finding that progesterone receptor expression was markedly downregulated in CI. Furthermore, the inhibitory effect of progesterone on lipopolysaccharide-induced inflammatory stimuli was also impaired in CI. These results suggest that abnormal cervical ripening in CI is caused by the downregulation of progesterone signalling at the receptor level, and provide a novel insight into the molecular mechanism of PTB.

When a woman presents with an acute abdomen with cystic lesions in the abdominal cavity, the differential diagnosis includes torsion or rupture of an ovarian tumor. We report our experience with a 54-year-old nulliparous woman who underwent emergency surgery for a suspected ruptured ovarian tumor. Intraoperative examination revealed disruption of a cystic tumor that had developed externally from the fundus of the uterus. The patient, who was taking aspirin because of a history of medullary infarction, reported lower abdominal discomfort for several days. When she sought care, she was referred to the gynecology department where transvaginal ultrasonography and contrast-enhanced computed tomography showed a poorly toned mass with a maximum diameter of 20 cm posterior to the uterus. She also had a large amount of ascites reaching around the liver and the spleen. She underwent an emergency laparotomy for a presumed diagnosis of acute abdomen caused by a ruptured ovarian tumor with intra-abdominal bleeding. Intraoperative examination revealed normal adnexae bilaterally, but there was a cystic tumor in the pouch of Douglas that was strongly adherent to the surrounding intestines. This mass was connected to the posterior uterus by a stalk and appeared to be continuous with the uterine tissue. The postoperative pathological diagnosis was carcinosarcoma derived from subserous cystic adenomyosis. This is the first case report of carcinosarcoma developing from subserous cystic adenomyosis in the English literature as far as we know.
RESUMO
Purpose: Since 1986, the Japan Society of Obstetrics and Gynecology assisted reproductive technology (ART) registry system has collected data on national ART use and outcomes trends in Japan. Herein, we describe the characteristics and outcomes of ART cycles registered during 2020 and compare the results with those from 2019. Methods and Results: In 2020, 621 ART facilities participated in the registration. The total number of registered cycles was 449 900, and there were 60 381 live births, which decreased from the previous year (1.79% and 0.36% decrease, respectively). The number of freeze-all in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) cycles increased in 2020, and the number of neonates born was 2282 for IVF-embryo transfer (ET) cycles and 2596 for ICSI cycles, which had decreased from the previous year. Frozen-thawed ET (FET) cycles had slightly increased from 2019 (0.04%). In 2020, 215 285 FET cycles were conducted, resulting in 76 196 pregnancies and 55 503 neonates. Single ET was performed in 81.6% of fresh transfers and 85.1% of frozen-thawed cycles, respectively, resulting in over 97% singleton pregnancies/livebirths rates. Conclusion: Despite the COVID-19 pandemic during 2020, the overall number of ART cycles and neonates born demonstrated only a slight decrease in 2020 compared with 2019.
RESUMO
On the basis of postoperative histopathological findings, a 29-year-old nulliparous woman was diagnosed as having ovotesticular disorder of sex development (DSD). She had undergone unilateral gonadectomy at age 6 years and vulvoplasty and vaginoplasty at age 8 years. Her karyotype was 46, XX. She had dyspareunia because of a narrow vagina, but her uterus and left gonad were normal. Spontaneous ovulation was confirmed, but sexual intercourse was impossible because of dyspareunia, despite vaginal self-dilatation with a vaginal dilator. Artificial insemination was initiated; however, five cycles failed to yield a viable pregnancy. We decided to perform in vitro fertilization (IVF), which resulted in conception. During IVF we administered intravenous anesthesia before oocyte collection to reduce her distress due to insufficient lumen expansion after vaginoplasty. The patient delivered a healthy male infant weighing 2,558 g at 37 weeks of gestation via cesarean section, which was performed because of gestational hypertension. This is the eighth report of a viable neonate born from a patient with ovotesticular DSD after gonadectomy and the first such pregnancy achieved by IVF. Therefore, IVF may be an effective option for infertile patients with ovotesticular DSD. Additionally, to prevent dyspareunia, self-management of the plastic vagina is important during the peri- and postoperative periods of early vaginoplasty.

A pregnant woman with severe aplastic anemia was managed using biweekly red blood cell transfusion and oral eltrombopag olamine administration during pregnancy. She was diagnosed with preeclampsia at 35 weeks of gestation. The severity of aplastic anemia is very important for predicting the course of pregnancy.
RESUMO
Purpose: Granulysin is a cytotoxic protein that simultaneously activates innate and cellular immunity. The authors aimed to evaluate whether granulysin is associated with the antiphospholipid antibody syndrome and whether heparin changes the granulysin levels. Methods: A cohort study was performed with women with antiphospholipid antibody-positive recurrent pregnancy loss (RPL). The authors examined granulysin levels under RPL and evaluated the changes in serum granulysin levels before and 1 week after the commencement of heparin treatment. Results: Serum granulysin levels before heparin treatment were significantly higher in women who tested positive for one or more types of antiphospholipid antibodies (2.75 ± 1.03 vs. 2.44 ± 0.69, p = 0.0341 by Welch's t test), particularly anti-phosphatidylethanolamine antibodies (IgG: 2.98 ± 1.09 vs. 2.51 ± 0.86, p = 0.0013; IgM: 2.85 ± 1.09 vs. 2.47 ± 0.77, p = 0.0024 by Welch's t test). After heparin treatment for 1 week, serum granulysin levels were significantly reduced (p = 0.0017 by the paired t test). The miscarriage rate was significantly higher in women whose serum granulysin levels were not reduced by heparin treatment (p = 0.0086 by Fisher's exact probability test). Conclusion: The results suggest that heparin may reduce the incidence of miscarriage by suppressing serum granulysin levels.
RESUMO
AIM: The fetal sample used for embryonic chromosome analysis is often contaminated with maternal cells, making it difficult to evaluate the fetal chromosomes. We examined on the rate of maternal cell contamination and its relationship with maternal information in the embryonic chromosome analysis of missed abortions using the Giemsabanding method. METHODS: Chromosome analysis was performed in 200 cases of delayed miscarriages in first trimester between July 1, 2000 and May 31, 2019. Chorionic villi were collected and were analyzed using the Giemsa banding method. Among the 20 cells for which chromosomal examination was performed, cells wherein 46,XX chromosomes were found together with normal male karyotype or abnormal chromosomes were defined as maternal cell contamination. RESULTS: Of the 200 cases analyzed, 136 had abnormal chromosomes. The normal female karyotype (n = 52) was four times more prevalent than the normal male karyotype (n = 12). Maternal cell contamination was seen in 15.4% of the abnormal chromosome cases and 8.3% of the normal male karyotype cases. There was no significant difference in the gestational age between the contaminated and noncontaminated groups at the time of miscarriage diagnosis. However, miscarriage before fetal heartbeat confirmation was significantly associated with higher maternal cell contamination. CONCLUSION: We found maternal cell contamination in 15% of all the cases. Moreover, in many cases of the normal female karyotype, it was suspected that only maternal chromosomes were cultured. When performing embryonic chromosome analysis in recurrent miscarriages, we should pay attention to maternal cell contamination and interpret the results accordingly.

Purpose: The Japan Society of Obstetrics and Gynecology records online annual cycle-based information for assisted reproductive technology (ART). This report presents the characteristics and treatment outcomes of ART cycles registered during 2019. Methods: The Japanese ART registry includes cycle-specific information from 619 participating facilities, including treatment and pregnancy outcomes. Descriptive analyses were conducted for cycles registered during 2019. Results: In 2019, 458 101 treatment cycles and 60 598 neonates were reported, both of which increased from 2018. The number of fresh cycles, including in vitro fertilization and intracytoplasmic sperm injection, decreased, while frozen-thawed embryo transfer (ET) cycles increased. The mean maternal age was 37.9 years (standard deviation ± 4.7). Of 239 348 oocyte retrievals, 123 690 (51.7%) involved freeze-all-embryos cycles; fresh ET was performed in 41 831 cycles (a decreasing trend since 2015). In 2019, there were 211 597 frozen-thawed ET cycles, resulting in 74 882 pregnancies and 54 168 neonates born. Single ET was performed in 82.6% of fresh transfers and 85.1% of frozen-thawed cycles, with singleton live birth rates of 97.3% for both. Conclusions: The number of fresh cycles decreased but frozen cycles increased in 2019. Single ET was performed in >80% of cases, and the proportion of babies born from frozen-thawed ET increased.
RESUMO
BACKGROUND: Miscarriage occurs in 10-15% of pregnancies and recurrent pregnancy loss (RPL) occurs in 1% of couples hoping for a child. Various risk factors, such as thrombophilia, uterine malformation, and embryonic chromosomal aberration cause RPL. We hypothesized that antithrombotic therapy for RPL patients with thrombophilia would reduce miscarriage due to thrombophilia, which would reduce the total miscarriages and result in a relative increase in miscarriage due to embryonic chromosomal aberrations. In this study, we investigated the incidence of chromosomal aberrations in products of conception in RPL patients with and without antithrombotic therapy. METHODS: We performed a single-center, retrospective review of cases diagnosed as miscarriage with embryo chromosome analysis between July 1, 2000, and May 31, 2019. Rates of chromosomal aberration were compared between RPL patients with and without thrombophilia or antithrombotic therapy. RESULTS: One hundred and-ninety RPL cases were analyzed. The average age was 37.4 ± 4.3 years, and the average number of previous pregnancy losses was 2.2 ± 1.1. The overall chromosomal aberration rate was 67.4% (128/190). There was no difference in the chromosomal aberration rate between the factors for RPL, with or without thrombophilia, and antithrombotic therapy. Only advancing maternal age had significant correlation to increased embryo chromosomal aberration rates. CONCLUSIONS: With or without antithrombotic therapy, miscarriage was caused by embryonic chromosome abnormalities at a certain rate. Antithrombotic therapy in RPL patients with thrombophilia may reduce abortions due to thrombophilia, which may also normalize the rate of embryonic chromosome aberrations in the subsequent miscarriages.

At the 73rd Annual Congress of the Japan Society of Obstetrics and Gynecology, young doctors from Japan and South Korea made presentations on the present condition of risk-reducing surgery for hereditary breast and ovarian cancer (RRSO) in their respective country. RRSO was insured in Japan in April 2020, whereas in South Korea, it was insured 7 years earlier in 2013. In Japan, certification criteria have been set for facilities that perform RRSO, and the number of facilities is increasing, but regional disparities still exist in its distribution. The number of gBRCA1/2 testing facilities is larger, and the cost is more affordable in South Korea than in Japan. Additionally, South Korea provides genetic counseling to a wider range of relatives compared to Japan. In the future, as the indications for the gBRCA1/2 test have expanded as a companion diagnostic for the use of PARP inhibitors, it is expected that the number of candidates for the gBRCA1/2 mutation test and RRSO will increase in Japan. It is important to increase the number of BRCA tests while maintaining the quality of genetic counseling in order to provide adequate information on BRCA mutations and RRSO for patients to support their decision. For the development of hereditary breast and ovarian cancer (HBOC) medical care, it is necessary to publish a nationwide database in Japan and continue to analyze and discuss the data based on the results.

Osteopontin (OPN) is a multifunctional secreted glycoprotein. We evaluated OPN concentrations in blood and follicular fluid (FF) during the ovarian cycle and their relationship with the production of vascular endothelial growth factor (VEGF), which is involved in the pathophysiology of ovarian hyperstimulation syndrome (OHSS). Twenty-two women undergoing in vitro fertilization (minimal stimulation protocol with clomiphene citrate) were enrolled. Samples were collected (a) on the third day of withdrawal bleeding, (b) 2 days before oocyte retrieval, and (c) on the day of oocyte retrieval. FF was collected during oocyte retrieval. The OPN concentration in each specimen and the VEGF concentration in FF was measured by enzyme-linked immunosorbent assays. Plasma OPN concentrations were (in ng/mL): (a) 416 ± 37.2, (b) 378 ± 35.8, and (c) 390 ± 40.0, with no significant differences between the groups. The OPN concentration in FF was 106 ± 13.4 ng/mL. A positive correlation was found between OPN concentrations in FF and plasma samples. A positive correlation was also found between plasma OPN and FF VEGF concentrations, irrespective of the blood-sampling period. Plasma OPN concentration is suggested to reflect the FF VEGF level at oocyte retrieval and maybe a novel clinical marker for predicting the risk for OHSS.

PURPOSE: Since 2007, the Japan Society of Obstetrics and Gynecology (JSOG) has collected cycle-based data for assisted reproductive technology (ART) in an online registry. Here, we present the characteristics and treatment outcomes of ART cycles registered during 2018. METHODS: The Japanese ART registry consists of cycle-specific information for all ART treatment cycles implemented at 621 participating facilities. We conducted descriptive analyses for such cycles registered for 2018. RESULTS: In total, 454 893 treatment cycles and 56 979 neonates were reported in 2018: both increased from 2017. The mean maternal age was 38.0 years (standard deviation ± 4.7). Of 247 402 oocyte retrievals, 118 378 (47.8%) involved freeze-all-embryos cycles; fresh embryo transfer (ET) was performed in 50 463 cycles: a decreasing trend since 2015. A total of 199 914 frozen-thawed ET cycles were reported, resulting in 69 357 pregnancies and 49 360 neonates born. Single ET (SET) was performed in 82.2% of fresh transfers and 83.4% of frozen-thawed cycles, with singleton pregnancy/live birth rates of 97.2%/97.2% and 97.0%/97.2%, respectively. CONCLUSIONS: Total ART cycles and subsequent live births increased in 2018. SET was performed in over 80% of cases, and the mode of ET has shifted continuously from using fresh embryos to frozen-thawed ones compared with previous years.
RESUMO
Nine years after the first edition of The Guideline for Gynecological Practice, which was jointly edited by The Japan Society of Obstetrics and Gynecology and The Japan Association of Obstetricians and Gynecologists, the 4th Revised Edition was published in 2020. The 2020 Guidelines includes 4 additional clinical questions (CQ), which brings the total to 99 CQ (12 on infectious disease, 29 on oncology and benign tumors, 29 on endocrinology and infertility and 29 on healthcare for women). Currently, a consensus has been reached on the Guidelines, and therefore, the objective of this report is to present the general policies regarding diagnostic and treatment methods used in standard gynecological outpatient care that are considered appropriate. At the end of each answer, the corresponding Recommendation Level (A, B, C) is indicated.

PROBLEM: Acute chorioamnionitis (aCAM) associated with microbial infection is a primary cause of preterm birth (PB). However, recent studies have demonstrated that innate immunity and sterile inflammation are causes of PB in the absence of aCAM. Therefore, we analyzed immune cells in the decidua of early to moderate PB without aCAM. METHOD OF STUDY: Deciduas were obtained from patients with PB at a gestational age of 24+0 to 33+6 weeks without aCAM in pathological diagnosis. The patients were divided into two groups as follows: patients with labor and/or rupture of membrane (ROM) (no aCAM with labor and/or ROM: nCAM-w-LR), and patients without labor and/or ROM (no aCAM without labor and/or ROM: nCAM-w/o-LR). The immune cells and high mobility group box 1 (HMGB1) levels in the decidua were analyzed using flow cytometry. Co-culture of CD56+ cells with dendritic cells (DCs) and macrophages obtained from the decidua was also performed in the presence of HMGB1. RESULTS: The nCAM-w-LR group demonstrated an accumulation of iNKT cells, and increased expression of HMGB1, TLR4, receptors for advanced glycation end products, and CD1d on DCs and macrophages. HMGB1 facilitated the proliferation of iNKT cells co-cultured with DCs and macrophages, which was found to be inhibited by heparin. CONCLUSIONS: Inappropriate activation of innate immune cells and increased HMGB1 expression may represent parturition signs in human pregnancy. Therefore, control of these cells and HMGB1 antigenicity may be represent a potential therapeutic target for the prevention of PB.

AIM: Women undergoing infertility treatment often need to balance work and fertility treatment. Therefore, we evaluated the quality of life (QOL) and impact of infertility treatment on Japanese working women and their careers. METHODS: We conducted an online questionnaire at 18 clinics in Japan. Responses were collected from 835 women, 713 of whom were working. The participants were divided into three groups based on treatment stage. Data were collected using the FertiQoL and an original questionnaire created by the authors. The Mann-Whitney U test and a multinomial logistic analysis were used. RESULTS: Approximately 90% of the participants felt that treatment could hinder their work and 8% had quit their jobs. Low QOL was associated with sadness and despair due to infertility and mood disorders, disruptions to life and work, and the complicated medications and procedures involved in treatment. Social isolation and the effect of fertility treatment on daily life and work strongly hindered the careers of working women in the third stage of treatment (in vitro fertilization and intracytoplasmic sperm injection). Approximately 70% of the participants required support to subsidize treatment costs and sought shorter working hours and flextime systems. Only 55% informed their workplaces about the fertility treatment, but about 70% easily gained understanding by informing them. CONCLUSIONS: For many working women, infertility treatment posed barriers to their careers, which could explain the low QOL. Urgent introduction of a support system is necessary in Japan, and understanding and social acceptance of infertility appears to be important.

Anti-phosphatidylethanolamine antibody (aPE), an anti-phospholipid autoantibody (aPL), has been proposed as a factor in recurrent pregnancy loss (RPL). However, conflicting views exist on the pathogenicity of RPL, and aPE has not yet been included in the classification criteria for antiphospholipid syndrome (APS). Here, we aimed to determine the clinical importance of examining aPE. aPE (IgG, IgM) was measured in 1705 patients with a history of RPL and re-examined after a 12-week interval in patients who tested positive. Persistent positive patients were administered low-dose aspirin during the subsequent pregnancy and clinical outcomes depending on the presence, type, and persistence of aPE were evaluated. Among the patients positive for aPE IgG and aPE IgM in the first examination (n = 117; 6.87%, and n = 235; 13.6%, respectively), 31.5% and 37.6% were negative upon re-examination, respectively. Moreover, among the cases with known pregnancy outcome, the miscarriage rate in the cumulative positive aPE group was 32.6% (29/89), which did not differ significantly from that of the aPE negative group (27.7%; 80/209; P = 0.178). Alternatively, the miscarriage rate in the persistently positive group was 40.7% (22/54), which was significantly higher than that in the transient positive group, 20.0% (7/35) (P = 0.041). Particularly, this difference become more significant when focusing on aPE IgM, 46.9% (15/32) in the persistent, compared with 16.7% (4/24) in the transient positive group (P = 0.024). aPE IgM is suggested to serve as a pathogenic aPL together with anti-cardiolipin antibodies and lupus anticoagulants, particularly if these factors persist over an extended period of time.
