Background Per- and polyfuoroalkyl substances (PFAS) are categorized as persistent organic pollutants and commonly detected in humans, and their toxicity has attracted widespread attention. However, few studies have reported comparison of PFAS levels and potential factors between women pregnant using assisted reproduction technology (ART) and women pregnant naturally. Objective To analyze and compare serum concentrations and sociodemographic determinants of PFAS in pregnant women conceiving through ART and conceiving naturally from Shanghai. Methods Based on the China National Birth Cohort (CNBC) in Shanghai from 2017 to 2019, 333 pregnant women conceiving through ART and 689 pregnant women conceiving naturally were recruited during the same period as study subjects. The concentrations of 32 PFAS were measured in early-pregnancy serum of all pregnant women, and four PFAS with the highest co-exposure levels in both groups were included in the subsequent analysis. Multiple linear regression models were performed to evaluate the associations of sociodemographic factors with serum PFAS concentrations in the two groups respectively. Beta coefficients and 95% confidence intervals (CI) were exponentiated to calculate the ratio of the geometric mean (GM) of PFAS concentrations after each unit change in the independent variable. Results Perfluorooctanoic acid (PFOA), perfluorooctanesulfonic acid (PFOS), 6∶2 chlorinated polyfluoroethersulfonic acid (6∶2 Cl-PFESA), and perfluorohexanesulfonic acid (PFHxS) were four major PFAS in serum of pregnant women conceiving through ART and conceiving naturally, and the concentrations of PFOA, PFOS, and 6∶2 Cl-PFESA were higher in pregnant women conceiving through ART than in pregnant women conceiving naturally (P <0.05). The results of multiple linear regression analysis showed that age at pregnancy and household income were associated with serum PFAS levels in both groups. The serum concentrations of PFOS were higher in pregnant women aged ≥35 years old who conceiving through ART (GM ratio=1.26, 95%CI: 1.04, 1.54) and conceiving naturally (GM ratio=1.24, 95%CI: 1.08, 1.42) than pregnant women aged <30 years old respectively. Pregnant women conceiving through ART and conceiving naturally whose household annual income >300000 CNY had lower serum concentrations of PFOA [GM ratio (95%CI): 0.82 (0.72, 0.95) and 0.89 (0.81, 0.97), respectively] and PFHxS [GM ratio (95%CI): 0.66 (0.51, 0.86) and 0.77 (0.66, 0.90), respectively] than those women whose household annual income <200000 CNY. Additionally, pregnant women conceiving naturally with a graduate education or above had lower serum 6∶2 Cl-PFESA concentrations than women with an education below college (GM ratio: 0.81), and multiparous pregnant women conceiving naturally had higher serum concentrations of PFOS, 6∶2 Cl-PFESA, and PFHxS than primiparous pregnant women (GM ratio: 1.14, 1.25, and 1.27 respectively). Conclusion Although differences in serum PFAS levels are found between pregnant women conceiving through ART and women conceiving naturally in this study, maternal age and household income are common determinants of PFAS exposure levels in both populations. We find no special sociodemographic factors to affect PFAS concentrations of pregnant women conceiving through ART compared to pregnant women conceiving naturally. Further research is required to explore other potential factors.

Background Pesticide exposure may impact the reproductive health of women undergoing assisted reproductive technology (ART). However, data on pesticide exposure levels in women undergoing ART in China are scarce, and current research on influencing factors is limited. Objective To evaluate the preconceptional pesticide exposure levels and identify potential determinants among women undergoing ART. Methods This study was designed as a cross-sectional survey and recruited 508 women undergoing ART from July 2017 to December 2018 at the fertility clinic of the International Peace Maternity and Child Health Hospital Affiliated to Shanghai Jiao Tong University School of Medicine. Gas chromatography/liquid chromatography-tandem mass spectrometry was used to determine the metabolite concentrations of organophosphate pesticides (OPs), pyrethroid pesticides (PYRs), and neonicotinoid pesticides (NEOs) in urine. The sum of molar concentrations of the three pesticide classes (∑2OPs, ∑2PYRs, and ∑2NEOs) were calculated. A questionnaire was used to collect demographic characteristics, dietary habits, and behavioral information. Multiple linear regression was employed to analyze the associations of demographic characteristics, dietary habits, and behavioral variables with the concentrations of pesticide metabolites in urine among the participants. Results The median creatinine-adjusted concentrations of ∑2OPs, ∑2PYRs, and ∑2NEOs in this study were 419.77, 2.95, and 20.36 nmol·g−1, respectively. The multiple linear regression results showed that the urinary concentration of ∑2OPs was 42.88% higher in the participants with daily vegetable intake than in those who consumed vegetables ≤3 d per week (P<0.05), and the urinary concentration of ∑2PYRs was 37.24% higher in the participants with daily fruit intake than in those who consumed fruits ≤3 d per week (P<0.01). Similarly, the urinary concentrations of ∑2NEOs were 24.51% and 29.30% higher in the participants who consumed fruits daily and 4-6 d per week, respectively, than in those who consumed fruits ≤3 d per week (P<0.05). Besides, we also found that the urinary concentration of ∑2PYRs was negatively correlated with body mass index (BMI) in the participants (P<0.05). Furthermore, the urinary concentration of ∑2NEOs was not only positively correlated with age (P<0.05), but also significantly associated with pet ownership and infertility causes among the participants. Specifically, the participants who continued to own pets after conception had a 30.11% higher urinary concentration of ∑2NEOs than those who never owned pets (P<0.05), and the participants with infertility due to female factors had a 24.10% lower urinary concentration of ∑2NEOs than those who received ART treatment for infertility caused by male factors (P<0.05). Conclusion The women undergoing ART in Shanghai are widely exposed to pesticides. Age, BMI, frequency of vegetable and fruit intake, pet ownership, and infertility causes may be related to the pesticide exposure levels in this population. However, more human data are needed to confirm these findings.

Infertile women experience complex biological and social experiences in the process of receiving IVF. From the perspective of females undergoing IVF, it is helpful to analyze the ethical and social problems that IVF may face more intuitively and concretely. In this study, 213 women who were undergoing IVF were randomly selected to carry out a questionnaire survey. The results showed that the choice of IVF for infertile women was driven by multiple pressures from family and society, not entirely on their own; They are not aware of the technology, but have a positive attitude, and are eager to be fully informed in the treatment process. In addition, the treatment brings great economic pressure to women who were undergoing IVF and has no significant impact on the relationship between husband and wife. Only by paying attention to the above problems and solving them can we benefit more infertile women and help them realize their reproductive wishes.

Abstract Background: Melatonin is a hormone produced by the pineal gland and it has antioxidant properties. Aim: This study aimed to evaluate the effects of melatonin on assisted reproductive technologies through a systematic review and a meta-analysis. Materials and methods: Search strategies were used in PubMed and in other databases covering the last 15 years. After screening for eligibility, 17 articles were selected for the systematic review. For the meta-analysis statistics, two groups were formed, the treatment group (with melatonin) and the control group (without melatonin) for various assisted reproduction outcomes. Results: The main results were that no statistical differences were found concerning the clinical pregnancy outcome (p = 0.64), but there was a statistical difference with respect to Mature Oocytes (MII) (p = 0.001), antral follicle count (p = 0.0002), and the fertilization rate (p ≤ 0.0001). Conclusions: Melatonin had beneficial effects such as the improvement in the fertilization rate, although the authors did not obtain significance in the clinical pregnancy rate.

Infertile couples seeking treatment experience a social stigma that can lead to the need for privacy and, in turn, compromise their access to social support. This multiple case study, that involved the collection of sociodemographic and health data and interviews with four heterosexual couples accessed by convenience, aimed to examine the perception of the couples about the social support received after the disclosure of the condition of infertility and/or of the assisted reproductive technology treatment. The cases were analysed individually and comparatively. From the couples' statements, it is highlighted that all of them revealed something about infertility and/or treatment at some point in the process, although some considered not revealing it. Both support and lack of support were perceived from the revelations. The non-disclosure was motivated by self-preservation and by avoidance of social pressure. The findings indicate the importance of psychological intervention to expand the couples' social support.
Parejas infértiles que buscan tratamiento experimentan un estigma social que puede acarrear la necesidad de privacidad y, a su vez, comprometer el acceso al apoyo social. Ese estudio de múltiples casos, que involucró la recogida de datos sociodemográficos, de salud y entrevistas con cuatro parejas heterosexuales accedidas por conveniencia, buscó examinar la percepción de las parejas sobre el apoyo social después de la revelación de la condición de infertilidad y/o del tratamiento con técnicas de reproducción asistida. Los casos fueron analizados individual y comparativamente. De las declaraciones de las parejas, se destaca que todas revelaron algo sobre la infertilidad y/o el tratamiento en algún momento del proceso, aunque algunos consideraron no revelarlo. Se percibió tanto el apoyo como la falta de apoyo a partir de las revelaciones. La no revelación fue motivada por la autopreservación y por la evitación de presión social. Los hallazgos indican la importancia de la intervención psicológica para ampliar el apoyo social de las parejas.

ObjectiveTo investigate the application of optical genome mapping （OGM） technology in detecting complex chromosomal rearrangement. MethodsWe recruited five patients who were diagnosed as complex chromosomal rearrangement at the Reproductive Medicine Center of the Sixth Affiliated Hospital of Sun Yat-sen University from January 2022 to June 2023. They underwent OGM， nanopore sequencing and pre-implantation genetic testing （PGT）. The results were compared with the results of karyotype and chromosomal microarray analysis （CMA）/ copy number variation sequencing （CNV-Seq）. ResultsOGM could detect translocation， invert inversion， and triplet translocation， which were consistent with the results of OGM and CMA/ CNV-Seq. But OGM could not detect Robertsonian translocation. ConclusionBecause of its ultra-long reads， OGM realizes the detection across repetitive regions， and it has great advantages when applied in patients with complex chromosome rearrangement or uncertain karyotype analysis. It can accurately locate breakpoints.

O presente artigo objetiva refletir sobre o discurso moral midiático produzido em torno da Inseminação Caseira e seu uso como tecnologia reprodutiva por casais de mulheres lésbicas. Esta é uma modalidade reprodutiva autônoma, que consiste em uma autoinseminação de baixo custo, feita com o uso de material biológico de doador não anônimo. Para esta reflexão, utilizou-se cinco obras midiáticas produzidas por canais de comunicação de grande alcance no cenário nacional, analisadas sob a ótica da análise do discurso. Foram traçadas cinco categorias analíticas: apresentação textual-imagética das obras; narrativa das mulheres tentantes; discursos promovidos pelos ditos especialistas; e representação da figura do doador. Conclui-se pela necessidade de estímulo ao debate acerca da inseminação caseira realizada por mulheres lésbicas, de modo que tanto profissionais da área da saúde como a sociedade de uma forma geral não se baseiem apenas em discursos morais condenatórios ditos científicos, como aqueles propagados pela grande mídia em relação à Inseminação Caseira. Soma-se a isso a importância em garantir visibilidade para os relatos das mulheres que estão se submetendo à inseminação caseira, compreendendo-as enquanto protagonistas da produção de sua saúde sexual e reprodutiva e projetos parentais e que, por isso, devem ter seus discursos e experiências legitimados.
The present article aims to reflect on the media moral discourse produced around Homemade Insemination and its use as a reproductive technology by lesbian couples. This is an autonomous reproductive modality, which consists in a low-cost self-insemination performed with the use of biological material from a non-anonymous donor. This reflection was made using five media works produced by communication channels of great reach in the Brazilian scenario, analyzed from the point of view of discourse analysis. Five analytical categories were drawn: textual-imagetic presentation of the works; narrative of women trying to conceive; speeches promoted by the so-called experts; and representation of the donor figure. We conclude that it is necessary to stimulate the debate about homemade insemination performed by lesbian women, so that both health professionals and society in general do not rely only on condemning moral speeches called scientific, such as those propagated by the media in relation to Homemade Insemination. Added to that it is important to ensure visibility of the reports of women who are submitting themselves to homemade insemination, understanding them as protagonists of the production of their sexual and reproductive health and parental projects and that, therefore, they must have their speeches and experiences legitimated.
Este artículo pretende reflexionar sobre el discurso moral mediático producido sobre la Inseminación Domiciliaria y su uso como tecnología reproductiva por parejas lesbianas. Se trata de una modalidad reproductiva autónoma, que consiste en una autoinseminación de bajo coste realizada con el uso de material biológico de donante no anónimo. Para esta reflexión, se utilizaron cinco obras mediáticas producidas por canales de comunicación de gran alcance en Brasil analizadas desde la perspectiva del análisis del discurso. Se trazaron cinco categorías analíticas: presentación textual-imagen de las obras; narración de las mujeres que intentan; discursos promovidos por los llamados especialistas; y representación de la figura del donante. Se concluye por la necesidad de estimular el debate sobre la Inseminación Domiciliaria realizada por mujeres lesbianas, de manera que tanto los profesionales de salud como la sociedad en general no se basen apenas en los discursos morales condenatorios de los científicos, como los propagados por la gran prensa sobre Inseminación Domiciliaria. A esto se suma la importancia de garantizar la visibilidad de los relatos de las mujeres que hacen la Inseminación Domiciliaria, entendiéndolas como protagonistas de la producción de su salud sexual y reproductiva y de sus proyectos parentales y debe tener sus discursos y experiencias legitimados.

Background: Comparative features of embryos developed under in vitro and in vivo conditions are particularly important in designing embryo transfer procedures that fulfil embryo-recipient synchronization requirements. Objective: To determine the degree of asynchrony in rabbit embryo development between cultured and in vivo embryos. Methods: A total of 55 non- lactating multiparous female rabbits were used. Embryos were classified as 16-cells or early morulae at 48 hours post-coitum (hpc). Embryos were cultured during 30 or 32 h and embryo development was compared with in vivo embryos of 72 hpc. In vitro and in vivo embryos at 72 hpc were classified as early or compacted morulae. Bayesian statistics was used. Difference between in vivo and in vitro embryos and the actual probability of the difference between the in vivo and in vitro embryo higher than zero (P) was estimated. Results: The percentage of compacted morulae was higher in in vivo embryos than in in vitro embryos with +6 h of asynchrony (73.5 and 32.8%, P=1.00). But the percentage of compacted morulae was similar with +8 h asynchrony. Conclusions: In vitro embryos delay their development by + 8 hours compared to in vivo embryos.
Antecedentes: El desarrollo comparativo de embriones producidos in vitro e in vivo es particularmente importante para el diseño de procedimientos de transferencia de embriones cuando se requiere sincronización entre el embrión y la hembra receptora. Objetivo: Determinar el grado de asincronía en el desarrollo embrionario entre embriones in vivo y cultivados. Métodos: Un total de 55 conejas multiparas no lactantes fueron utilizadas. Los embriones se clasificaron en 16 células o mórulas tempranas a las 48 horas después del coito (hpc). Los embriones se cultivaron durante 30 ó 32 horas y el desarrollo embrionario se comparó con embriones de 72 hpc obtenidos in vivo. Los embriones in vitro e in vivo a 72 hpc se clasificaron como mórulas tempranas o compactas. Se utilizó estadística bayesiana. Se estimó la diferencia entre embriones in vivo e in vitro y la probabilidad de que la diferencia sea superior a cero (P). Resultados: El porcentaje de mórulas compactas fue mayor en embriones in vivo que en embriones in vitro con +6 horas de asincronía (73,5 y 32,8%, P=1,00), pero el porcentaje de mórulas compactas fue similar con asincronía de +8 horas. Conclusión: Los embriones cultivados retrasan +8 horas su desarrollo en comparación con los embriones in vivo.
Antecedentes: A aquisição do desenvolvimento de embriões produzidos in vitro e in vivo é particularmente importante na concepção de procedimentos de transferência de embriões em que a sincronização entre o embrião e a fêmea receptora é necessária. Objetivo: Determinar o grau de assincronia no desenvolvimento embrionário entre embriões cultivados e in vivo. Métodos: Um total de 55 coelhos multíparos não lactantes foram usados. Os embriões foram classificados em 16 células ou mórulas iniciais 48 horas de gestação (hpc). Os embriões foram cultivados por 30 ou 32 horas e o desenvolvimento embrionário foi comparado com embriões de 72 hpc obtidos in vivo. Embriões in vitro e in vivo a 72 hpc foram classificados como mórulas precoces ou compactadas. Estatísticas bayesianas foram usadas. A diferença entre embriões in vivo e in vitro e a probabilidade de que a diferença seja maior que zero (P) foi estimada. Resultados: A porcentagem de mórulas compactadas foi maior em embriões in vivo do que em embriões in vitro com +6 horas de assincronia (73,5 e 32,8%, P=1,00). Mas a porcentagem de mórulas compactadas foi semelhante com assincronia de +8 horas. Conclusão: Embriões cultivados atrasam seu desenvolvimento em +8 horas em comparação com embriões in vivo.

Resumen El concepto de familia ha cambiado con los años y la constitución de los hogares en Chile ya no es la misma que hace un siglo. Las familias diversas en nuestro país han existido durante toda la vida, pero el conocimiento de cómo se han constituido y la existencia de un catastro en Chile son escasos. El objetivo de esta revisión es mostrar cómo se han constituido las familias diversas en Chile, cómo ha sido el acceso de estas a las técnicas de reproducción asistida, cuál ha sido la política del Estado y las aseguradoras de salud (Fonasa e Isapres) en las coberturas, y qué ha pasado con la legislación a lo largo de los años que ha facilitado la constitución de nuevas familias. Por otra parte, se pretende mostrar cuáles son las barreras al acceso por parte de las familias diversas y la necesidad de una ley de reproducción asistida que permita el acceso a todas las personas independientemente de su estado civil, orientación sexual o identidad de género, y que proteja a todos los nacidos chilenos por igual.
Abstract The image of a typical family has changed in recent years, as the makeup of households in Chile is no longer the same as decades ago. While gender and sexual diverse families in our country have always existed, there is a scarcity of reliable data. We review the evolution of the makeup of these diverse families in Chile and their access to assisted reproduction techniques. We also review national policies and health insurance coverage by both governmental and private carriers (Fonasa and Isapres) and how changes in legislation over the years have facilitated the constitution of these families. We outline barriers to access assisted reproduction techniques and the need for further legislative action to guarantee access to all citizens regardless of their marital status, sexual orientation, or gender identity.

O Conselho Federal de Medicina acaba de editar a Resolução nº 2.294/2021, publicada em 15 de junho de 2021, que aponta normas para a utilização das técnicas de reprodução assistida. Apesar de o propósito ser o aperfeiçoamento das práticas e a observância aos princípios éticos e bioéticos para trazer maior segurança e eficácia a tratamentos e procedimentos médicos, repete inconstitucionalidades das normatizações pretéritas e impõe mais restrições ao sonho das pessoas de ter filhos. Desse modo, mais do que avanços, o novo regramento provoca um retrocesso que não se coaduna com a garantia constitucional e legal que assegura o livre planejamento familiar.(AU)
The Brazilian Federal Council of Medicine has just edited the Resolution nº 2.294/2021, published on June 15, 2021, which sets out rules for the use of assisted reproduction techniques. Although the purpose is to improve practices and observe ethical and bioethical principles to bring greater safety and efficacy to medical treatments and procedures, it repeats the unconstitutionalities of past regulations and imposes more restrictions on people's dreams of having children. In this way, more than advances, the new regulation provokes a setback that is not consistent with the constitutional and legal guarantees of free family planning.(AU)

Este estudo objetivou compreender a experiência da parentalidade de um casal heterossexual que recorreu à ovodoação e que tevetrigêmeos. O casal respondeu, individualmente, as entrevistas sobre maternidade e paternidade em três períodos: gestação, três meses e primeiro ano de vida dos bebês. Após repetidas leituras das entrevistas, construiu-se o relato clínico. Os resultados revelaram questionamentos da mãe sobre a própria maternidade e uma compensação exacerbada nos cuidados com os bebês para suprir a ligação não consanguínea com os filhos. Além disso, as dúvidas a respeito da revelação da origem dos trigêmeos demonstraram angústia e desamparo frente ao contexto da ovodoação.
This study aimed to understand the parenting experience of a heterosexual couple who resorted to egg donation and who had triplets. The couple responded individually to interviews about motherhood and paternity in three periods: pregnancy, three months and the babies' first year of life. After repeated readings of the interviews, the clinical report was constructed. The results revealed questions from the mother about her own motherhood and an exacerbated compensation in the care of the babies to supply the non-consanguineous connection with the children. In addition, doubts about the disclosure of the triplets' origin showed anguish and helplessness in the context of egg donation.

RESUMEN La gestación por sustitución contribuye a la transformación de las concepciones sociales de la filiación y los cambios en las estrategias reproductivas de las familias. En la presente contribución se relaciona la teoría de la atención reproductiva transfronteriza con las teorías posmodernas de la vida familiar, con el propósito de explorar qué temáticas, elementos y contenidos utilizan las agencias intermediarias de gestación por sustitución que tienen por destinatarios a las madres y padres de intención españoles. Se utiliza la metodología cualitativa y la técnica de análisis de contenido temático tras el registro de la información online recogida de las agencias. Los resultados evidencian el papel de estas agencias mediadoras en los procesos de gestación por sustitución en España, además de generar conocimiento en el área de las nuevas formas familiares constituidas mediante técnicas de reproducción asistida.
ABSTRACT Substitution pregnancy contributes to the transformation of social conceptions of filiation and changes in the reproductive strategies of families. This contribution relates the theory of cross-border reproductive care with post-modern theories of family life in order to explore which themes, elements and contents are used by intermediary surrogate pregnancy agencies which target Spanish mothers and fathers. The qualitative methodology and the technique of thematic content analysis after registration of the online information collected from the agencies is used. The results show the role of these intermediary agencies in the process of gestation by substitution in Spain, as well as generating knowledge in the area of new family forms constituted by assisted reproduction techniques.

INTRODUCCIÓN Y OBJETIVOS: La infertilidad es una enfermedad altamente prevalente que afecta aproximadamente a un 8-10% de las parejas en edad reproductiva. Las Técnicas de Reproducción Asistida (TRA) han experimentado un importante incremento en el número de tratamientos realizados, no obstante, el acceso en Chile sigue siendo limitado y centralizado. El presente estudio resume la experiencia y los resultados de TRA del primer trienio del Centro de Reproducción Humana de la Universidad de Valparaíso (CRHUV). MÉTODOS: Estudio de cohorte retrospectiva de las pacientes sometidas a TRA en el CRHUV desde 1 de enero de 2015 a 31 diciembre 2017. Se realizó un análisis descriptivo e inferencial. La distribución de variables fue analizada con la prueba de Shapiro-Wilk. Para variables cualitativas se usó la prueba exacta de Fisher. RESULTADOS: Se iniciaron un total de 581 ciclos. Para un total de 340 ciclos en fresco con ovocitos propios, la tasa de embarazo (TE) y de parto (TP) por ciclo aspirado fue de 43,5% y 36,7% respectivamente. En el mismo grupo, la TE y TP por transferencia embrionaria fue de un 48,4% y un 40,9% respectivamente, siendo superior al comparar transferencia doble con un embrión (p < 0,05). También se observó un aumento de TE en menores de 35 años (p < 0,05). La TE y TP por transferencia embrionaria fue semejante en transferencia de embriones frescos y congelados. Al transferir embriones producto de ovocitos donados se observó un incremento significativo de la TE y TP con tasas de 73,1% y 61,5% respectivamente. Las tasa globales y estratificadas de embarazo y parto fueron comparables en el trienio estudiado con los resultados de la REDLARA. CONCLUSIÓN: La exitosa implementación del CRHUV se respalda en los resultados comparables a lo reportado por literatura internacional.
INTRODUCTION AND OBJECTIVES: Infertility is a highly prevalent disease that affects approximately 8-10% of couples in reproductive age. Assisted reproduction techniques (ART) have experienced a significant increase in the number of treatments performed, however, access in Chile remains limited and centralized. This study summarizes the experience and results of the first triennium of the Center for Human Reproduction of the Universidad de Valparaíso (CRHUV). METHODS: Retrospective cohort study of patients undergoing ART at the CRHUV from January 1, 2015 to December 31, 2017. A descriptive and inferential analysis was performed. The distribution of the variables was analyzed with the Shapiro-Wilk test. For qualitative variables, Fisher's exact test was used. RESULTS: A total of 581 cycles were started. For a total of 340 fresh cycles with own oocytes, the pregnancy (RP) and delivery (DR) rate per oocyte retrival was 43.5% and 36.7%. In the same group, PR and DR per embryo transfer was 48.4% and 40.9%, being higher when comparing double with a single embryo transfer (p <0.05). A higher PR was also observed in < 35 years patients (p <0.05). The PR and DR per embryo transfer was similar using fresh and frozen embryo. In oocytes donation, a significant increase in PR and RD per embryo transfer was observed with rates of 73.1% and 61.5%, respectively. The global and stratified rates of pregnancy and delivery were comparable in the studied triennium compared to the results of REDLARA. CONCLUSION: The successful implementation of the CRHUV is supported by results comparable to those reported by international literature.

Objective To explore the relationship between clinical outcomes and embryo transfer number, and to provide some proposals for transfer selection of elderly patients. Methods Data from 80 fresh transfer cycles with cleavage-stage embryos were analyzed. Cycles were divided into several groups according to transfer number. Clinical pregnancy rate, implantation rate, multiple pregnancy rate and live birth rate were compared. Results To women no younger than 38 years old, when available embryo number was larger than two, similar clinical outcomes could be achieved by transferring two and three embryos. This trend was independent of the number of transferred 8-cell embryos. Conclusion The number of fresh cleavage-stage embryos transfer should not exceed two in elderly women.

Objective:To observe the effect of modified Wuzi Yanzongwan periodic staging treatment on the outcome of assisted pregnancy in patients with poor ovarian response （POR） and kidney deficiency syndrome. Method:One hundred and four patients were randomly divided into observation group and control group， with 52 cases in each group. Both groups received gonadotropin releasing hormone （GnRH） antagonist regimen. The patients in control group additionally took Bushen Yutaiwan orally， 5 g/time， 3 times/day. The patients in observation group additionally took modified Wuzi Yanzongwan during pre-ovulation and post-ovulation periods， 1 dose/day. The treatment courses were 3 menstrual cycles （or termination after clinical pregnancy） in both groups. The number of eggs obtained， the number of available embryos， the number of fertilization， the number of high-quality embryos， the number of embryos implanted， the number of cycles cancelled， and the clinical pregnancy were recorded. Human chorionic gonadotropin （HCG） was injected， and then follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， estrogen （E<sub>2</sub>）， anti-Müllerian hormone （AMH）， basal antral follicle count （AFC） and endometrial thickness were measured daily. The number of days and dosage of Gn used， scores of kidney deficiency syndrome were recorded before and after treatment， and the adverse reactions during the study period were recorded. Result:The number of eggs captured， rate of harvested eggs， number of available embryos， rate of available embryos， number of high-quality embryos， rate of high-quality embryos， and fertilization rate in observation group were higher than those in control group （<italic>P</italic><0.05 or <italic>P</italic><0.01）. The cycle cancellation rate was lower than that in the control group； the embryo implantation rate and clinical pregnancy rate were superior than those in control group， but the difference was not statistically significant. The FSH level and FSH/LH ratio in observation group were lower than those in control group during HCG day （<italic>P</italic><0.01）， while E<sub>2</sub>， AMH， AFC and endometrial thickness were higher than those in control group （<italic>P</italic><0.01）. Simultaneously， the number of days and amount of Gn used in observation group was lower than that in control group （<italic>P</italic><0.01）. Conclusion:The Modified Wuzi Yanzongwan periodic staging treatment combined with GnRH antagonist scheme for patients with POR kidney deficiency syndrome， can regulate the level of endocrine hormones， promote follicular development， improve ovarian reserve， increase the number of eggs obtained， improve egg quality， help improve pregnancy outcomes， and increase the chances of successful pregnancy with assisted reproductive technology. It is worthy of further clinical research.
