<p><strong>Study question: </strong>How does testosterone gender-affirming hormone therapy (T-GAHT) impact breeding success in female mice?</p><p><strong>Summary answer: </strong>T-GAHT causes reversible subfertility in female mice and persistent changes to reproductive tract anatomy, gene expression, and hormone receptors.</p><p><strong>What is known already: </strong>Adult female mice implanted with capsules containing 10 mg of testosterone mimic many aspects of reproductive phenotypes of T-GAHT patients, who may desire future gestation while pausing T-GAHT. In mice, oocytes retrieved from T-GAHT mice had decreased IVF rates, and T cessation prior to stimulation improved these outcomes. However, the effects of T-GAHT on breeding have not been examined.</p><p><strong>Study design, size, duration: </strong>Adult female CD1 mice were subcutaneously implanted with capsules containing 10 mg of testosterone or blank controls. In separate studies, capsules were removed after 6 ('short') or 12 weeks ('long' n = 15/group), then mice were paired with proven-breeder CD1 males. Breeding pair success and pup development (15-20/group) were measured for first and second litters, then terminal measurements were taken from dams and their adult offspring (10/group).</p><p><strong>Participants/materials, setting, methods: </strong>The reproductive success of explanted T-GAHT and control mice was investigated by pairing them with proven-breeder CD1 males. Regular observations of dams and litters enabled analysis of fertility and the development of male and female pups for two litters. Terminal measures for dams and/or adult offspring focused on endpoints tied to reproductive tract function and gestation, including reproductive hormones, vaginal cytology, sperm analysis and ovarian and uterine anatomy, histology, and gene expression.</p><p><strong>Main results and the role of chance: </strong>All but one T-GAHT dams gave birth, but the time between pairing and their first birth was longer than controls after long (22.3 ± 1.3 days vs 24.5 ± 3.1) and short (23.2 ± 1.4 days vs 25.5 ± 4) treatments. Dams given long T-GAHT treatment had fewer pups in their first litters (11.9 ± 2.7 pups vs 7.8 ± 3.1) but pup number was unaltered after short treatment (11.5 ± 2.4 pups vs 11.4 ± 3.7).

STUDY QUESTION Does maternal age impact hormonal secretions from granulosa cells, theca cells, and the oocyte in human small antral follicles? SUMMARY ANSWER Major hormones secreted by granulosa and theca cells, as well as the oocyte-specific TGF-β members—GDF9, BMP15, and the GDF9/BMP15 heterodimer cumulin—maintain a consistent concentration within the follicular fluid of human small antral follicles, regardless of maternal age. WHAT IS KNOWN ALREADY It is well established that female fertility declines with increasing age. However, it is not known whether this decline is exclusively due to a reduction in oocyte quality and quantity or also involves a decline in the hormone-secreting capabilities of granulosa cells, theca cells, and the oocyte itself. STUDY DESIGN, SIZE, DURATION This is a retrospective study of follicular fluid obtained from human small antral follicles collected in connection with cryopreservation of ovarian tissue at the Laboratory of Reproductive Biology, University Hospital Copenhagen, Rigshospitalet, Denmark, between 2010 and 2020 as part of the hospital’s fertility preservation program. PARTICIPANTS/MATERIALS, SETTING, METHODS Follicular fluid samples from human small antral follicles measuring 3–13 mm in diameter from macroscopically normal ovaries of 381 patients aged 5–43 years were included in the study, provided that at least one of the following parameters was measured: AMH, Inhibin A, Inhibin B, oestradiol (E2), progesterone (P4), androstenedione, testosterone, and/or the oocyte-specific TGF-β members GDF9, BMP15, or cumulin. MAIN RESULTS AND THE ROLE OF CHANCE In a linear regression analysis adjusted for follicular volume, female age did not predict the follicular fluid concentrations of AMH, Inhibin B, Inhibin A, E2, androstenedione, testosterone, GDF9, BMP15, or cumulin. Although a significant association was observed between female age and follicular fluid P4 levels, the predictive value of age was poor, accounting for at most 5% of the variation in P4. LIMITATIONS, REASONS FOR CAUTION Hormonal levels may vary with the degree of atresia in each follicle; however, the health status of the small antral follicles in this study was not characterized. Additionally, we cannot exclude possible age-related differences in human follicles larger than 10 mm, as very few of these were included. Furthermore, we did not include women above the age of 43, despite the potential for more pronounced age-related effects in these patients. WIDER IMPLICATIONS OF THE FINDINGS Our results support the idea that the age-related decline in female fertility is primarily due to a reduction in oocyte quality and quantity, but further research is needed to confirm this. STUDY FUNDING/COMPETING INTEREST(S) No specific funding was obtained, and the authors have no conflicts of interest to declare in relation to this work. TRIAL REGISTRATION NUMBER N/A.

<p><strong>Study question: </strong>Does the slow-freezing and thawing process have a negative impact on the transcriptome of oocytes isolated from early-stage human follicles compared to fresh controls?</p><p><strong>Summary answer: </strong>The transcriptional profiles of fresh and frozen/thawed oocytes did not cluster separately, indicating undetectable differences between the two groups when compared to within-donor heterogeneity.</p><p><strong>What is known already: </strong>Previous studies using histological analysis of follicle morphology, density, and stage distribution in slow-frozen/thawed human ovarian cortex compared to fresh controls showed no differences between the two groups. Clinical cases reported in the past 10 years have demonstrated that transplanted slow-frozen/thawed and fresh ovarian cortex restored normal serum FSH levels and regular menstrual cycles by 5 months. However, the slow-frozen and thawed tissue resulted in lower rates of pregnancies and live births, albeit not statistically significant.</p><p><strong>Study design, size, duration: </strong>We utilized single-cell RNA-sequencing (scRNAseq) of 144 human oocytes isolated from cadaver ovaries obtained from three donors.</p><p><strong>Participants/materials, setting, methods: </strong>Human ovarian cortex from three healthy premenopausal donors 16, 18, and 27 years old was cut into squares measuring 10 × 10 × 1 mm3 and either slow-frozen and thawed or processed fresh. First, using a novel method for isolating live oocytes from primordial and primary follicles, the ovarian cortex squares were fragmented with a McIlwain tissue chopper and enzymatically digested. Next, oocytes were mechanically denuded under a dissection microscope and placed individually into wells containing lysis buffer for scRNAseq. Lysed single oocytes were subjected to library prep using the seqWell PlexWell rapid single-cell RNA protocol. Pooled libraries were subjected to 150-bp paired-end sequencing on the NovaSeq6000 Illumina platform.

STUDY QUESTION Does the number of biopsied trophectoderm cells sampled for preimplantation genetic testing for monogenic disease (PGT-M) affect subsequent clinical outcomes for those selected embryos? SUMMARY ANSWER The number of biopsied cells does not affect the pregnancy outcome of preimplantation genetically tested embryos. WHAT IS KNOWN ALREADY The successful execution of PGT relies on the availability of a certain number of high-quality biopsied cells. Evidence in the literature has reported that blastocyst biopsies may have a negative impact on clinical outcomes. STUDY DESIGN, SIZE, DURATION A retrospective cohort study including 850 single-blastocyst transfer cycles from 605 couples between May 2014 and August 2024 was conducted at Peking University Third Hospital. The primary clinical outcome measure was the biochemical pregnancy rate, while other indicators such as the live birth rate, the clinical pregnancy rate, and the miscarriage rate were also recorded. PARTICIPANTS/MATERIALS, SETTING, METHODS This study included 850 blastocysts obtained from routine PGT-M cycles. Based on biopsied cell numbers, data were categorized into four groups: Group 1 (1–5 cells) (n = 234), Group 2 (6–10 cells) (n = 328), Group 3 (11–15 cells) (n = 192), and Group 4 (&gt;15 cells) (n = 96). MAIN RESULTS AND THE ROLE OF CHANCE The number of cells biopsied from the embryo did not significantly affect either the biochemical pregnancy rate or the live birth rate in the routine PGT process (P &gt; 0.05). There were 129 of 234 embryos (55.1%) in the 1–5 biopsied cell group, 183 of the 328 embryos (55.8%) with 6–10 biopsied cells, 92 of 192 embryos (47.9%) with 11–15 biopsied cells, and 48 of 96 (50.0%) embryos with more than 15 biopsied cells which achieved successful pregnancies. The live birth rates were 42.7%, 49.7%, 43.2%, and 43.8% for each of the biopsy groups, respectively. LIMITATIONS, REASONS FOR CAUTION Data for this study were collected from one center only, therefore multicenter, large-scale cohort studies are essential to confirm the accuracy and the reliability of this study. WIDER IMPLICATIONS OF THE FINDINGS The number of biopsied cells in a blastocyst is associated with the embryo quality and hatching status. The conclusion of this study emphasizes that routine procedures during the biopsy process do not affect pregnancy outcomes. It is crucial to strike a balance between minimizing damage to the blastocyst’s developmental potential and achieving the highest possible detection efficiency for PGT-M. STUDY FUNDING/COMPETING INTEREST(S) This project is funded by the National Key Research and Development Program of China (2019YFA0801401, 2019YFA0110001) and the National Natural Science Foundation of China (82125013).

研究问题:特纳综合征患者及其家庭成员患生殖或结肠癌的风险是否增加?总结回答:我们的数据表明,患有特纳综合征的女性患乙状结肠癌的风险增加,二、三度男性亲属患前列腺癌的风险增加。已知情况:特纳综合征与较低的乳腺癌风险有关,但在一些研究中(但不是全部)发现,它会增加患性腺母细胞瘤和结肠癌的风险。也有证据表明性染色体非整倍体的遗传易感性,这可能表明家庭成员易患特纳综合征和相关的癌症风险。研究设计、规模、持续时间:该研究是一项回顾性病例对照研究,研究对象为1995年至2021年诊断为特纳综合征的妇女、她们的亲属和犹他州的人群。参与者/材料、环境、方法:使用来自犹他州两个主要医疗保健系统的电子病历中的国际疾病分类(ICD)代码识别特纳综合征妇女,并对其准确性进行审查。患有特纳综合征的妇女与犹他州人口数据库中的家谱相关联。癌症诊断(乳腺癌、卵巢癌、子宫内膜癌、结肠癌、睾丸癌和前列腺癌)由犹他州癌症登记处确定。患有特纳综合症的妇女的活产是通过相关的出生证明来确定的。特纳综合征妇女及其亲属患癌症的相对风险是通过与年龄、性别和出生地相匹配的人口比率进行比较来估计的。主要结果和偶然性的作用:我们确定了289名患有特纳综合征的妇女。患有特纳综合征的女性乙状结肠癌发生率增加(OR [95% CI] 24.2 [2.9, 87.4];p = 0.0032)。有233名患有特纳综合征的女性至少有三代的家谱数据。第一组患者发生特纳综合征的风险增加(OR [95% CI] 18.08 [2.19, 65.32];P = 0.0057)和二度亲属(9.62 [1.17,34.74];P = 0.019),尽管数量很小。第二组患者患前列腺癌的风险增加(1.8 [1.4,2.2];P局限性,谨慎的原因:基于乙状结肠病例较少,我们的数据可能高估了结肠癌的风险。局限性包括在犹他州的两个主要卫生系统之一通过诊断代码识别特纳综合征。人口主要是北欧人,9.3%的女性自认为是西班牙裔,2.4%的女性自认为是美洲原住民或多种族。研究结果可能不适用于其他人群。研究结果的更广泛意义:我们的数据表明,患有特纳综合征的女性可能需要早期结肠癌筛查。需要进一步的研究来确定特纳综合征女性及其男性亲属性染色体非整倍体和癌症风险的危险因素。研究经费/竞争利益:本文工作由R56HD090159和R01HD099487 (C.K.W.)资助。我们也感谢国家癌症研究所通过P30 CA2014拨款对犹他州人口数据库的部分支持。犹他州癌症登记处由国家癌症研究所SEER项目资助,合同编号:HHSN261201800016I,美国疾病控制与预防中心国家癌症登记项目,合作协议号:NU58DP007131,得到了犹他大学和亨茨曼癌症基金会的额外支持。内容完全是作者的责任,并不一定代表美国国立卫生研究院的官方观点。作者没有利益冲突。试验注册号:无。

<p><strong>Study question: </strong>How does pre-diagnosis use of hospital care differentiate between women later diagnosed with endometriosis and age-matched controls without a diagnosis?</p><p><strong>Summary answer: </strong>Women with hospital-diagnosed endometriosis had more frequent hospital contacts in the 10 years leading up to the diagnosis compared to women without a diagnosis of endometriosis, and the contacts were related to registered diagnoses in nearly all of the included ICD-10 chapters for the entire period.</p><p><strong>What is known already: </strong>Only a few studies have investigated the utilization of health care among women with endometriosis in the time before diagnosis, but current research shows that women with endometriosis have a higher utilization compared to women without diagnosed endometriosis. To our knowledge, no study has investigated the type of contact related to the higher utilization by using the ICD-10 diagnoses registered to the hospital contact.</p><p><strong>Study design, size, duration: </strong>This study was conducted as a national Danish registry-based case-control study of 129 696 women. Cases were women with a first-time hospital-based diagnosis of endometriosis between 1 January 2000 and 31 December 2017.</p><p><strong>Participants/materials, setting, methods: </strong>Using density sampling, we identified 21 616 cases. Each case was matched on age at the date of diagnosis (index date) to five women without hospital-diagnosed endometriosis (n = 108 080) at the time of matching. The utilization and registered ICD-10 diagnoses related to the hospital contact were included for the 10 years before the index date.</p><p><strong>Main results and the role of chance: </strong>The probability of having a high number of hospital contacts (six or more) was more common among women with endometriosis (68.6%) compared to women without endometriosis (55.7%) In general, women without endometriosis were more likely to have fewer than six contacts. The diagnoses registered to the contact among cases were related to a greater variety of ICD-10 chapters when compared to controls with the same number of contacts. For nearly all of the included ICD-10 chapters, women with endometriosis were more likely to have a diagnosis over the entire period compared to controls, with the only exception being in the chapter related to pregnancy.</p><p><strong>Limitations, reasons for caution: </strong>Our results are only applicable for women with hospital-based diagnosed endometriosis since we were not able to include women diagnosed at the general practitioner or private gynecologists.

研究问题:诊断前使用医院护理如何区分后来诊断为子宫内膜异位症的妇女和未诊断的年龄匹配的对照组?概要回答:在诊断出子宫内膜异位症之前的10年里,与没有诊断出子宫内膜异位症的女性相比,患有子宫内膜异位症的女性与医院的接触更频繁,而且在整个期间,这些接触与ICD-10中几乎所有章节的登记诊断有关。已知情况:只有少数研究调查了诊断前子宫内膜异位症妇女对医疗保健的利用情况,但目前的研究表明,与未诊断为子宫内膜异位症的妇女相比,患有子宫内膜异位症的妇女对医疗保健的利用更高。据我们所知,没有研究调查过使用医院联系人登记的ICD-10诊断与较高利用率相关的接触类型。研究设计、规模、持续时间:本研究是丹麦一项以登记为基础的病例对照研究,纳入1229696名女性。病例为2000年1月1日至2017年12月31日期间首次在医院诊断为子宫内膜异位症的妇女。参与者/材料、环境、方法:采用密度抽样法,共发现21 616例病例。每个病例在诊断日期(索引日期)的年龄与5名在匹配时没有医院诊断的子宫内膜异位症的妇女(n = 108080)相匹配。纳入索引日期前10年与医院接触相关的ICD-10使用情况和登记诊断。主要结果和偶然性的作用:子宫内膜异位症患者(68.6%)与非子宫内膜异位症患者(55.7%)相比,与医院接触次数较多(6次或更多)的可能性更大。总的来说,没有子宫内膜异位症的女性更有可能少于6次接触。与接触人数相同的对照组相比,病例中接触者的诊断与ICD-10章节的多样性更大。在ICD-10的几乎所有章节中,与对照组相比,患有子宫内膜异位症的女性在整个期间更有可能被诊断出来,唯一的例外是与怀孕有关的章节。局限性和谨慎的原因:我们的结果只适用于在医院诊断为子宫内膜异位症的妇女,因为我们不能包括在全科医生或私人妇科医生诊断的妇女。我们无法作出因果解释,因为我们没有关于所包括疾病症状发作的信息。由于检测偏差,这种关联可能被高估。然而,敏感性分析只略微改变了结果,表明这种偏倚的风险很低。研究结果的更广泛意义:这项研究与之前的研究一致,表明子宫内膜异位症前的医疗保健利用并不一定局限于子宫内膜异位症相关症状,子宫内膜异位症可能与许多其他疾病有关。未来的研究可能会探索子宫内膜异位症诊断后的医院联系和原因/诊断,以进一步阐明我们的结果是由于多种病理模式还是更确切地说是子宫内膜异位症女性在诊断前的误诊表达。研究资金/竞争利益:本研究由使用机器学习发现子宫内膜异位症项目(FEMaLe/101017562)资助,该项目已获得欧盟地平线2020研究与创新计划和Helsefonden (21-B-0141)的资助。A.W.H.获得了NIHR、CSO、罗氏诊断和妇女福利组织的资助。A.W.H.该机构从Theramex、Joii、Gesynta和Gedeon Richter那里获得了咨询费。A.W.H.该机构获得了Theramex和Gedeon Richter的讲座酬金。A.W.H.在一项专利申请中被列为共同发明人(英国专利申请号2217921.2,国际专利申请号2217921.2)。PCT / GB2023/053076)。P.T.K.S.英国爱丁堡大学(University of Edinburgh)获得了Gesynta Pharma AB和BenevolentAI Bio Ltd.的咨询费。P.T.K.S的机构(爱丁堡大学)宣布一项专利申请(英国专利申请号2310300.5)。雄激素在子宫内膜异位症诊断策略中的应用。P.T.K.S.是世界子宫内膜异位症协会的财务主管,爱丁堡皇家学会的奖学金,皇家妇产科学院的科学顾问。试验注册号:无。

The diagnoses registered to the contact among cases were related to a greater variety of ICD-10 chapters when compared to controls with the same number of contacts.

研究问题:如何将管理健康数据中报告的子宫内膜异位症的诊断和亚型与手术确诊的疾病进行比较?摘要回答:对于子宫内膜异位症的诊断,我们观察到行政健康数据-国际疾病分类(ICD) 9代码-在接受妇科腹腔镜或剖腹手术的参与者中进行手术确诊诊断之间存在实质性的一致性和高灵敏度和特异性。已知情况:几项研究已经评估了自我报告的子宫内膜异位症与医疗记录报告的有效性,发现了强有力的证实。我们之前在子宫内膜异位症,自然史,诊断和结果(ENDO)研究中报道了子宫内膜异位症诊断在外科医生之间和医生内部的高度一致性。研究设计、规模、持续时间:在这项验证性研究中,ENDO研究(2007-2009)犹他州手术队列的参与者(n = 412)与犹他州人口数据库(UPDB)的医疗记录相关联,以比较来自每个来源的子宫内膜异位症诊断。UPDB是一个独特的数据库,包含超过1100万人的关联数据,包括全州门诊和住院记录、州生命记录以及犹他大学健康和山间医疗保健电子医疗记录,涵盖了大多数犹他州居民。参与者/材料、环境、方法:ENDO手术队列包括年龄18-44岁,既往无子宫内膜异位症诊断,因各种手术指征接受妇科腹腔镜检查或剖腹手术的个体。总共有173名妇女根据手术显像诊断为子宫内膜异位症,其中35%为浅表性子宫内膜异位症,9%为卵巢子宫内膜异位症,14%为深浸润性子宫内膜异位症。来自UPDB的当代行政健康数据包括来自犹他州卫生部住院和门诊手术记录以及犹他大学和山间健康电子健康记录的ICD诊断代码。主要结果及偶发因素的作用:对于子宫内膜异位症的诊断,我们发现了较高的敏感性(0.88)和特异性(0.87),并有很大的一致性(Kappa [Κ] = 0.74)。我们发现浅表子宫内膜异位症(n = 143, 0.86, 0.83, Κ = 0.65)和卵巢子宫内膜异位症(n = 38, 0.82, 0.92, Κ = 0.58)的敏感性、特异性和一致性相似。而深浸润性子宫内膜异位症(n = 58)的敏感性(0.12)和一致性(Κ = 0.17)较低,特异性(0.99)较高。局限性和注意事项:药物处方数据和非结构化数据,如临床记录,不包括在本研究使用的UPDB数据中。这些额外的数据类型可以帮助检测子宫内膜异位症。大多数参与者是白人或亚洲人,西班牙裔占11%,这可能限制了美国一些州的普遍性。此外,考虑到我们使用的管理健康记录的参与者也是ENDO研究的一部分,外科医生可能在诊断编码方面更加警惕,因为他们为ENDO研究完成了手术表格,这可能导致有效性提高。但是,UPDB中比较的代码将由医疗编码员作为标准临床实践的一部分输入。研究结果的更广泛意义:我们观察到管理健康数据与手术确诊的子宫内膜异位症诊断之间的基本一致,以及浅表和卵巢子宫内膜异位症亚型。这些发现可能为研究人员使用行政医疗记录来评估子宫内膜异位症的危险因素和长期健康结果提供了保证。我们的研究结果证实了先前的研究表明,深浸润性子宫内膜异位症具有高特异性但低敏感性,这表明深浸润性子宫内膜异位症在行政保健数据中没有可靠的注释。这表明基于医疗记录的深浸润性子宫内膜异位症诊断可能适用于病因学研究,但不适用于监测或检测研究。研究经费/竞争利益:最初的ENDO研究由美国国立卫生研究院尤尼斯·肯尼迪·施莱弗国家儿童健康与人类发展研究所的校内研究项目资助(合同no . 1- dk -6-3428;一号门将- dk - 6 - 3427;10001406 - 02)。我们感谢犹他大学国家癌症研究所、犹他大学个性化健康项目和临床与转化科学中心通过P30 CA2014拨款对UPDB的部分支持。这项研究也得到了NCRR拨款“共享全州健康数据用于遗传研究”(R01 RR021746, G. Mineau, PI)的支持,并得到了犹他大学犹他州卫生与人类服务部的额外支持。此外,这项研究得到了犹他州癌症登记处的支持,该登记处由国家癌症研究所的SEER项目资助,合同编号: HHSN261201800016I,美国疾病控制与预防中心国家癌症登记项目,合作协议号:NU58DP007131,得到了犹他大学和亨茨曼癌症基金会的额外支持。本出版物中报道的研究还得到了美国国立卫生研究院(奖励号R01HL164715[给L.V.F, K.C.S.和A.Z.P.]和K01AG058781[给K.C.S.])、亨茨曼癌症研究所乳腺和妇科癌症中心以及由美国心脏协会资助的多丽丝·杜克基金会COVID-19基金以保留临床科学家的支持。A.C.K.得到了国家医学图书馆授予K.E.的培训基金编号5T15LM007124的支持。文章内容完全由作者负责,并不一定代表美国国立卫生研究院或其他赞助者的官方观点。在任何作者之间都没有竞争利益。试验注册号:无。
