    这项横断面观察性研究检查了症状负担之间的关联,雌激素暴露的终生持续时间,使用双变量偏倚校正的Pearson相关性和多重对应分析,HIV感染女性(n=98)的血清抗苗勒管激素(AMH)水平。大多数是黑人(85.6%)的女性样本,平均年龄为50岁(SD12.6岁),未表现出明显的生殖史因素和症状负担的相互关系,也未表现出雌激素暴露的终生持续时间和症状之间的显著关联。可以预见,老年妇女的血清AMH水平较低;然而,不可预测的是它与感染艾滋病毒的几个月的显著关系(r=-0.362),ART的月数(r=-0.270),和CD4+T细胞最低点(r=0.347)。症状-症状关系支持疲劳,疼痛,睡眠,焦虑,和抑郁症状集群。这些假设没有得到横断面观察的支持。进一步的研究应该探索HIV之间关系的变化,雌激素暴露,卵巢储备,和AMH水平随着时间的推移。
    UNASSIGNED: This cross-sectional observational study examined associations among symptom burden, lifetime duration of estrogen exposure, and serum antimüllerian hormone (AMH) levels among women living with HIV (n = 98) using bivariate bias-corrected Pearson correlations and multiple correspondence analyses. The mostly Black (85.6%) sample of women, with a mean age of 50 years (SD 12.6 years), exhibited no significant reproductive history factors and symptom burden interrelationships or significant associations between lifetime duration of estrogen exposure and symptoms. Predictably, serum AMH levels were lower among older women; however, less predictable were its significant relationships with months living with HIV (r = -0.362), months on ART (r = -0.270), and CD4+ T-cell nadir (r = 0.347). Symptom-symptom relationships support a fatigue, pain, sleep, anxiety, and depression symptom cluster. The hypotheses were not supported by cross-sectional observation. Further studies should explore variation in relationships between HIV, estrogen exposure, ovarian reserve, and AMH levels over time.

    本研究旨在确定GnRH拮抗剂原始参考产品Cetrotide®和通用Ferpront®之间的活产率是否相似,促性腺激素释放激素(GnRH)拮抗剂方案用于控制性卵巢刺激(COS)。
    这项回顾性队列研究调查了使用GnRH拮抗剂方案的COS周期。这项研究是在三级保健医院内的专业生殖医学中心进行的,从2019年10月到2021年10月。在这段时间内,总共924个周期使用GnRH拮抗剂的起源,四肽®(A组),而1984年的周期是使用通用的,Ferpront®(B组)。
    卵巢储备标志物,包括抗苗勒管激素,窦卵泡数,和基础卵泡刺激素,与B组相比,A组较低。进行倾向评分匹配(PSM)以平衡组间的这些标志物。PSM之后,基线临床特征相似,除了A组与B组的不育持续时间稍长(4.43±2.92年vs.4.14±2.84年,P=0.029)。B组比A组使用GnRH拮抗剂的持续时间稍长(6.02±1.41vs.5.71±1.48天,P<0.001)。与A组相比,B组的卵母细胞数量略低(14.17±7.30vs.14.96±7.75,P=0.024)。然而,在第3天发现的可用胚胎数量和优质胚胎数量相当.生殖结果,包括生化妊娠损失,临床妊娠,流产,和活产率,两组之间没有显着差异。多因素logistic回归分析显示,GnRH拮抗剂的类型并不独立影响卵母细胞的数量,有用的胚胎,优质的胚胎,中度至重度OHSS率,临床妊娠,流产,或活产率。
    回顾性分析显示,当Cetrotide®和Ferpront®在使用GnRH拮抗剂方案进行第一个和第二个COS周期的女性中使用时,在生殖结局方面没有临床显着差异。
    UNASSIGNED: This study aims to determine whether the live birth rates were similar between GnRH antagonist original reference product Cetrotide® and generic Ferpront®, in gonadotropin-releasing hormone (GnRH) antagonist protocol for controlled ovarian stimulation (COS).
    UNASSIGNED: This retrospective cohort study investigates COS cycles utilizing GnRH antagonist protocols. The research was conducted at a specialized reproductive medicine center within a tertiary care hospital, spanning the period from October 2019 to October 2021. Within this timeframe, a total of 924 cycles were administered utilizing the GnRH antagonist originator, Cetrotide® (Group A), whereas 1984 cycles were undertaken using the generic, Ferpront® (Group B).
    UNASSIGNED: Ovarian reserve markers, including anti-Mullerian hormone, antral follicle number, and basal follicular stimulating hormone, were lower in Group A compared to Group B. Propensity score matching (PSM) was performed to balance these markers between the groups. After PSM, baseline clinical features were similar, except for a slightly longer infertile duration in Group A versus Group B (4.43 ± 2.92 years vs. 4.14 ± 2.84 years, P = 0.029). The duration of GnRH antagonist usage was slightly longer in Group B than in Group A (6.02 ± 1.41 vs. 5.71 ± 1.48 days, P < 0.001). Group B had a slightly lower number of retrieved oocytes compared to Group A (14.17 ± 7.30 vs. 14.96 ± 7.75, P = 0.024). However, comparable numbers of usable embryos on day 3 and good-quality embryos were found between the groups. Reproductive outcomes, including biochemical pregnancy loss, clinical pregnancy, miscarriage, and live birth rate, did not differ significantly between the groups. Multivariate logistic regression analyses suggested that the type of GnRH antagonist did not independently impact the number of oocytes retrieved, usable embryos, good-quality embryos, moderate to severe OHSS rate, clinical pregnancy, miscarriage, or live birth rate.
    UNASSIGNED: The retrospective analysis revealed no clinically significant differences in reproductive outcomes between Cetrotide® and Ferpront® when used in women undergoing their first and second COS cycles utilizing the GnRH antagonist protocol.

    这项研究的目的是评估甲状腺自身免疫(TAI)与获取的卵母细胞数(NOR)的关联,受精率(FR),甲状腺功能正常的不孕和卵巢储备(DOR)减少的女性的胚胎质量(EQ)。
    这项回顾性队列研究涉及1,172名年龄在20-40岁的甲状腺功能正常的女性,患有不孕症和DOR,他们经历了一个取卵周期。在血清甲状腺过氧化物酶抗体(TPOAb)浓度高于34IU/ml和/或血清甲状腺球蛋白抗体(TgAb)浓度超过115.0IU/ml的情况下诊断为TAI。在这些女性中,147例TAI患者被归类为TAI阳性组,而1,025例无TAI的患者被归类为TAI阴性组。使用针对混杂因素进行调整的广义线性模型(GLM),我们评估了TAI与血清TPOAb和TgAb浓度和NOR的关系,FR,和EQ在这项研究的主题。对TPOAb和TGAb值进行log10转化以减少偏度。使用Logistic回归模型来估计TPOAb和TgAb浓度对实现高NOR(≥7)和高FR(>60%)的概率的影响。
    对于整个研究人群,与没有TAI的女性相比,患有TAI的女性的NOR和EQ显著降低(两者均P<0.001).有趣的是,在TSH≤2.5亚组中,与TAI阴性组相比,TAI阳性组的NOR和EQ也显著降低(两者均P<0.001).此外,在log10(TPOAb)浓度和NOR与优质胚胎和可用胚胎数量之间观察到负相关(全部P<0.05).log10(TgAb)浓度与NOR和高质量胚胎数量呈负相关(均P<0.05)。在回归分析中,log10(TPOAb)浓度达到高NOR的概率较低[校正比值比(aOR):0.56;95%置信区间(95%CI)0.37,0.85;P=0.007].
    TAI和较高的TPOAb和TgAb浓度显示与研究人群中NOR和EQ的降低相关。我们的发现提供了进一步的证据,以支持甲状腺功能正常的不孕和DOR女性TAI的系统筛查和治疗。
    UNASSIGNED: The aim of this study was to evaluate the associations of thyroid autoimmunity (TAI) with the number of oocytes retrieved (NOR), fertilization rate (FR), and embryo quality (EQ) in euthyroid women with infertility and diminished ovarian reserve (DOR).
    UNASSIGNED: This retrospective cohort study involved 1,172 euthyroid women aged 20-40 years with infertility and DOR who underwent an oocyte retrieval cycle. TAI was diagnosed in the presence of serum thyroperoxidase antibody (TPOAb) concentrations higher than 34 IU/ml and/or serum thyroglobulin antibody (TgAb) concentrations exceeding 115.0 IU/ml. Among these women, 147 patients with TAI were classified as the TAI-positive group, while 1,025 patients without TAI were classified as the TAI-negative group. Using generalized linear models (GLMs) adjusted for confounding factors, we evaluated the associations of TAI and the serum TPOAb and TgAb concentrations and NOR, FR, and EQ in this study\'s subjects. The TPOAb and TGAb values were subjected to log10 transformation to reduce skewness. Logistic regression models were used to estimate the effects of TPOAb and TgAb concentrations on the probabilities of achieving a high NOR (≥7) and high FR (>60%).
    UNASSIGNED: For the whole study population, women with TAI had a significantly lower NOR and poorer EQ than women without TAI (P < 0.001 for both). Interestingly, in the TSH ≤2.5 subgroup, the TAI-positive group also had a significantly lower NOR and poorer EQ than the TAI-negative group (P < 0.001 for both). Furthermore, negative associations were observed between log10(TPOAb) concentrations and NOR and the number of high-quality embryos and available embryos (P < 0.05 for all). The log10(TgAb) concentrations were inversely associated with NOR and the number of high-quality embryos (P < 0.05 for all). In the regression analysis, the log10(TPOAb) concentrations had lower probabilities of achieving a high NOR [adjusted odds ratio (aOR): 0.56; 95% confidence interval (95% CI) 0.37, 0.85; P = 0.007].
    UNASSIGNED: TAI and higher TPOAb and TgAb concentrations were shown to be associated with reductions in the NOR and EQ in the study population. Our findings provide further evidence to support systematic screening and treatment for TAI in euthyroid women with infertility and DOR.

    迄今为止,很少研究患有脊柱关节炎(SpA)的女性的生育能力。最近的系统综述和登记研究使人们重新关注患有风湿病的育龄妇女的困境,特别是SpA。生育率可能会受到身体损伤的影响,荷尔蒙失衡和心理困扰。一些研究观察到SpA女性的抗苗勒管激素减少,反映卵巢储备减少(OR)。此外,疾病活动和某些疗法的使用可以改变生育能力,这反映在延长的怀孕时间(TTP)上,一个经过验证的结果指标,可以评估低生育状态。糖皮质激素或非甾体抗炎药的使用也与生育能力下降有关,而生物制剂的使用,尤其是肿瘤坏死因子抑制剂(TNFi),与延长的TTP无关。在所有患有风湿病的育龄妇女中,先入为主的咨询,在存在可能影响生育能力的多种因素的情况下,应考虑转诊给生殖专家。涉及多学科风湿病学家团队的综合评估,妇科医生,心理学家往往是有必要的。在这篇叙述性评论中,我们收集了目前可用的文献,重点关注受SpA影响的女性的生育问题,提供生育结果的数据,荷尔蒙失衡,和治疗问题。
    The topic of fertility in women with spondyloarthritis (SpA) has been scarcely investigated to date. Recent systematic reviews and registry studies have brought renewed attention to the plight of women of childbearing age with rheumatic diseases, in particular SpA. Fertility may be impacted by physical impairment, hormonal imbalances and psychological distress. Several studies observed a reduction in anti-Müllerian hormone in women with SpA, reflecting a reduced ovarian reserve (OR). Furthermore, disease activity and the use of certain therapies can alter fertility, and this is reflected in a prolonged time-to-pregnancy (TTP), a validated outcome measure that can evaluate the status of subfertility. The employment of glucocorticoids or non-steroidal anti-inflammatory drugs has also been linked to reduced fertility, whereas the use of biologics, especially tumour necrosis factor inhibitors (TNFi), is not associated with a prolonged TTP. In all women of childbearing age with rheumatic diseases, preconception counselling is paramount, and a referral to a reproductive specialist should be considered in the presence of multiple factors that may influence fertility. A comprehensive evaluation involving a multidisciplinary team of rheumatologists, gynaecologists, and often psychologists is warranted. In this narrative review, we collected the currently available literature focusing on fertility issues in women affected by SpA, providing data on fertility outcomes, hormonal imbalance, and therapeutic concerns.

    背景:工业进步导致一般人群的环境中化学物质无处不在,包括育龄妇女和孕妇。女性的生殖功能是内分泌干扰化学物质的众所周知的目标。这一功能拥有生物过程,对妇女本身的生育能力和后代的健康具有决定性作用。然而,没有足够的研究评估了混合混合物对这一功能的风险。这项研究旨在评估实际暴露于八种联合环境毒物对卵泡发育关键过程的直接影响。
    方法:母兔每天口服八种环境毒物混合物(F组)或溶剂混合物(NE组,对照)从2到19周龄。根据先前的毒物动力学数据计算剂量,以在孕妇中遇到的范围内重现兔子的稳态血清浓度。通过卵巢的宏观和组织学分析评估卵巢功能,血清激素测定和类固醇生成酶表达的分析。用Ki67染色和TUNEL测定进一步研究卵巢中的细胞动力学。
    结果:F兔的生长与NE兔相似,但在成年期表现出更高的总胆固醇和高密度脂蛋白(HDL)胆固醇水平。他们还提出了显著升高的血清睾酮浓度,而雌二醇,黄体酮,AMH和DHEA水平未受影响。促性腺激素的测量,雄烯二酮,孕烯醇酮和雌酮水平的值低于定量限。在测试的7种类固醇生成酶中,在F兔卵巢中检测到Cyp19a1的分离较高表达。这些卵巢表现出明显更大的窦和闭锁卵泡的密度/数量以及更大的窦卵泡,而细胞增殖或DNA片段没有任何变化。其他卵泡阶段的计数没有发现差异,特别是原始阶段,黄体或AMH血清水平。
    结论:通过暴露于类似人类的环境毒物混合物,卵泡生成和类固醇生成似乎发生了微妙的改变。窦卵泡的生长似乎是由化学物质的数量和大小的混合物促进的,可能解释了闭锁窦卵泡的增加。令人放心的是,通过原始卵泡数量/密度和AMH估计的卵巢储备不受任何改变的影响。这些变化对生育力和后代健康的影响尚待研究。
    BACKGROUND: Industrial progress has led to the omnipresence of chemicals in the environment of the general population, including reproductive-aged and pregnant women. The reproductive function of females is a well-known target of endocrine-disrupting chemicals. This function holds biological processes that are decisive for the fertility of women themselves and for the health of future generations. However, insufficient research has evaluated the risk of combined mixtures on this function. This study aimed to assess the direct impacts of a realistic exposure to eight combined environmental toxicants on the critical process of folliculogenesis.
    METHODS: Female rabbits were exposed daily and orally to either a mixture of eight environmental toxicants (F group) or the solvent mixture (NE group, control) from 2 to 19 weeks of age. The doses were computed from previous toxicokinetic data to reproduce steady-state serum concentrations in rabbits in the range of those encountered in pregnant women. Ovarian function was evaluated through macroscopic and histological analysis of the ovaries, serum hormonal assays and analysis of the expression of steroidogenic enzymes. Cellular dynamics in the ovary were further investigated with Ki67 staining and TUNEL assays.
    RESULTS: F rabbits grew similarly as NE rabbits but exhibited higher total and high-density lipoprotein (HDL) cholesterol levels in adulthood. They also presented a significantly elevated serum testosterone concentrations, while estradiol, progesterone, AMH and DHEA levels remained unaffected. The measurement of gonadotropins, androstenedione, pregnenolone and estrone levels yielded values below the limit of quantification. Among the 7 steroidogenic enzymes tested, an isolated higher expression of Cyp19a1 was measured in F rabbits ovaries. Those ovaries presented a significantly greater density/number of antral and atretic follicles and larger antral follicles without any changes in cellular proliferation or DNA fragmentation. No difference was found regarding the count of other follicle stages notably the primordial stage, the corpora lutea or AMH serum levels.
    CONCLUSIONS: Folliculogenesis and steroidogenesis seem to be subtly altered by exposure to a human-like mixture of environmental toxicants. The antral follicle growth appears promoted by the mixture of chemicals both in their number and size, potentially explaining the increase in atretic antral follicles. Reassuringly, the ovarian reserve estimated through primordial follicles number/density and AMH is spared from any alteration. The consequences of these changes on fertility and progeny health have yet to be investigated.

    背景:化疗相关卵巢损伤(CAOD)是绝经前妇女抗癌治疗最可怕的短期和长期副作用之一。积累的详细数据表明,不同的化疗方案可导致卵巢激素水平紊乱,减少或失去生育能力,更年期提前的风险增加。以前的研究往往集中在化疗药物对卵巢卵泡的直接影响,如直接DNA损伤介导的凋亡性死亡和原始卵泡倦怠。新的证据表明化疗期间卵巢微环境失衡。卵巢微环境提供营养支持和运输刺激卵泡生长和发育的信号,排卵,黄体的形成.卵巢微环境与卵泡之间的紧密相互作用可以决定卵巢功能。因此,设计新颖而精确的策略来操纵卵巢微环境可能是化疗期间保护卵巢功能的新策略。
    目的:这篇综述详细介绍了化疗过程中卵巢微环境的变化,并强调了开发化疗过程中通过靶向卵巢微环境保护卵巢功能的新疗法的重要性。
    方法:通过检索截至2024年4月的PubMed对文献进行了全面回顾。搜索词包括\'卵巢微环境\'(卵巢细胞外基质,卵巢基质细胞,卵巢间质,卵巢血管,卵巢淋巴管,卵巢巨噬细胞,卵巢淋巴细胞,卵巢免疫细胞因子,卵巢氧化应激,卵巢活性氧,卵巢衰老细胞,卵巢衰老相关分泌表型,卵巢卵原干细胞,卵巢干细胞),与卵巢功能相关的术语(生殖健康,生育力,不孕症,繁殖力,卵巢储备,卵巢功能,更年期,卵巢储备减少,过早的卵巢功能不全/衰竭),和与化疗相关的术语(环磷酰胺,环磷酰胺,甲基氯,苯丁酸氮芥,白消安,melphalan,丙卡巴嗪,顺铂,阿霉素,卡铂,紫杉烷,紫杉醇,多西他赛,5-氟尿嘧啶,长春新碱,甲氨蝶呤,放线菌素,博来霉素,巯基嘌呤)。
    结果:化疗期间卵巢微环境有很大变化,诱导细胞外基质沉积和基质纤维化,血管生成障碍,免疫微环境干扰,氧化应激失衡,卵巢干细胞衰竭,和细胞衰老,从而降低卵泡的数量和质量。已经采用了几种针对卵巢微环境的方法来预防和治疗CAOD,如干细胞疗法和使用自由基清除剂,senolytherapies,免疫调节剂,和促血管生成因子。
    结论:卵巢功能取决于其“种子”(卵泡)和“土壤”(卵巢微环境)。据报道,卵巢微环境在CAOD中起着至关重要的作用,靶向卵巢微环境可能为CAOD提供潜在的治疗方法。然而,卵巢微环境之间的关系,它的监管网络,和CAOD需要进一步研究。对这些问题的更好理解可能有助于解释CAOD的发病机理,并创造创新的策略来抵消对卵巢功能的影响。我们的目标是对CAOD的叙事回顾将激发这一重要领域的更多研究。
    背景:不适用。
    BACKGROUND: Chemotherapy-associated ovarian damage (CAOD) is one of the most feared short- and long-term side effects of anticancer treatment in premenopausal women. Accumulating detailed data show that different chemotherapy regimens can lead to disturbance of ovarian hormone levels, reduced or lost fertility, and an increased risk of early menopause. Previous studies have often focused on the direct effects of chemotherapeutic drugs on ovarian follicles, such as direct DNA damage-mediated apoptotic death and primordial follicle burnout. Emerging evidence has revealed an imbalance in the ovarian microenvironment during chemotherapy. The ovarian microenvironment provides nutritional support and transportation of signals that stimulate the growth and development of follicles, ovulation, and corpus luteum formation. The close interaction between the ovarian microenvironment and follicles can determine ovarian function. Therefore, designing novel and precise strategies to manipulate the ovarian microenvironment may be a new strategy to protect ovarian function during chemotherapy.
    OBJECTIVE: This review details the changes that occur in the ovarian microenvironment during chemotherapy and emphasizes the importance of developing new therapeutics that protect ovarian function by targeting the ovarian microenvironment during chemotherapy.
    METHODS: A comprehensive review of the literature was performed by searching PubMed up to April 2024. Search terms included \'ovarian microenvironment\' (ovarian extracellular matrix, ovarian stromal cells, ovarian interstitial, ovarian blood vessels, ovarian lymphatic vessels, ovarian macrophages, ovarian lymphocytes, ovarian immune cytokines, ovarian oxidative stress, ovarian reactive oxygen species, ovarian senescence cells, ovarian senescence-associated secretory phenotypes, ovarian oogonial stem cells, ovarian stem cells), terms related to ovarian function (reproductive health, fertility, infertility, fecundity, ovarian reserve, ovarian function, menopause, decreased ovarian reserve, premature ovarian insufficiency/failure), and terms related to chemotherapy (cyclophosphamide, lfosfamide, chlormethine, chlorambucil, busulfan, melphalan, procarbazine, cisplatin, doxorubicin, carboplatin, taxane, paclitaxel, docetaxel, 5-fluorouraci, vincristine, methotrexate, dactinomycin, bleomycin, mercaptopurine).
    RESULTS: The ovarian microenvironment shows great changes during chemotherapy, inducing extracellular matrix deposition and stromal fibrosis, angiogenesis disorders, immune microenvironment disturbance, oxidative stress imbalances, ovarian stem cell exhaustion, and cell senescence, thereby lowering the quantity and quality of ovarian follicles. Several methods targeting the ovarian microenvironment have been adopted to prevent and treat CAOD, such as stem cell therapy and the use of free radical scavengers, senolytherapies, immunomodulators, and proangiogenic factors.
    CONCLUSIONS: Ovarian function is determined by its \'seeds\' (follicles) and \'soil\' (ovarian microenvironment). The ovarian microenvironment has been reported to play a vital role in CAOD and targeting the ovarian microenvironment may present potential therapeutic approaches for CAOD. However, the relation between the ovarian microenvironment, its regulatory networks, and CAOD needs to be further studied. A better understanding of these issues could be helpful in explaining the pathogenesis of CAOD and creating innovative strategies for counteracting the effects exerted on ovarian function. Our aim is that this narrative review of CAOD will stimulate more research in this important field.
    BACKGROUND: Not applicable.

    化疗是主要的癌症治疗方法之一。不幸的是,它的使用会导致一些副作用,包括绞股蓝对女性的影响。卵巢储备抑制和雌激素缺乏导致癌症患者的生活质量下降,并且经常是不孕和早期绝经的原因。在这方面,经典的烷基化细胞抑制剂是毒性最强的化学治疗剂之一。它们会导致卵巢卵泡及其所含的细胞的DNA损伤,它们还可以诱导氧化应激或影响许多信号通路。体外试验,动物模型,一些女性研究调查了在经典化疗期间各种药物对卵巢储备保护的影响。在这篇评论文章中,我们专注于选择的激素(抗苗勒管激素,ghrelin,黄体生成素,褪黑激素),影响凋亡途径活性和调节基因表达的试剂(C1P,S1P,microRNA),和几种天然(槲皮素,雷帕霉素,白藜芦醇)和合成化合物(硼替佐米,右旋雷佐生,戈舍瑞林,促性腺激素类似物,伊马替尼,二甲双胍,他莫昔芬)预防常用细胞抑制剂诱导的结氧效应。所提出的研究系列似乎为保护和/或改善癌症患者研究组的卵巢储备提供了有希望的策略。然而,需要精心设计的临床试验来明确评估这些药物对接受卵黄毒素抗癌药治疗的女性的激素功能和生育能力的改善作用.
    Chemotherapy is one of the leading cancer treatments. Unfortunately, its use can contribute to several side effects, including gynotoxic effects in women. Ovarian reserve suppression and estrogen deficiency result in reduced quality of life for cancer patients and are frequently the cause of infertility and early menopause. Classic alkylating cytostatics are among the most toxic chemotherapeutics in this regard. They cause DNA damage in ovarian follicles and the cells they contain, and they can also induce oxidative stress or affect numerous signaling pathways. In vitro tests, animal models, and a few studies among women have investigated the effects of various agents on the protection of the ovarian reserve during classic chemotherapy. In this review article, we focused on the possible beneficial effects of selected hormones (anti-Müllerian hormone, ghrelin, luteinizing hormone, melatonin), agents affecting the activity of apoptotic pathways and modulating gene expression (C1P, S1P, microRNA), and several natural (quercetin, rapamycin, resveratrol) and synthetic compounds (bortezomib, dexrazoxane, goserelin, gonadoliberin analogs, imatinib, metformin, tamoxifen) in preventing gynotoxic effects induced by commonly used cytostatics. The presented line of research appears to provide a promising strategy for protecting and/or improving the ovarian reserve in the studied group of cancer patients. However, well-designed clinical trials are needed to unequivocally assess the effects of these agents on improving hormonal function and fertility in women treated with ovotoxic anticancer drugs.

    背景:降低卵巢储备是乳腺癌使用化疗药物的关键长期副作用之一,产生早期卵巢功能衰竭。另一方面,维生素D是保护卵泡的重要因素,也是IVF治疗成功的重要预测因素。
    目的:这项研究的目的是评估维生素D作为一种药物,可以减少化疗的生育并发症,特别是年轻女性。
    方法:在两个癌症研究所接受化疗的乳腺癌患者被纳入本研究。病例组接受1000IU骨化三醇,在基线测量AMH水平,化疗后,化疗后六个月。主要终点是化疗6个月后AMH水平的改善。次要终点是评估化疗期间AMH水平下降的预测因素.
    结果:在2018年至2019年之间,病例组和对照组分别招募了18和15名患者,分别。病例组和对照组的平均AMH水平(ngr/ml)分别为3.16和2.37ng/mL,分别(p值=.16)。六个月后,这些水平分别为0.387和0.19(p值=0.38)。AMH在化疗周期后立即上升至化疗后6个月,病例组和对照组分别为0.86和0.44ng/mL,分别,在病例组中稍高,但两组之间无统计学意义(p值=.054)。
    结论:尽管化疗6个月后AMH水平有轻微上升,该研究未能证明维生素D对接受乳腺癌化疗的患者卵巢储备有任何保护作用.除了最佳剂量和持续时间外,还需要进一步更大的研究来评估维生素D补充剂对卵巢储备的影响。
    BACKGROUND: Reduced ovarian reserve is among the crucial long-term side effects of using chemotherapy agents in breast cancer, yielding early ovarian failure. On the other hand, vitamin D is an essential factor in protecting the follicles and an important predictive factor for successful IVF therapy.
    OBJECTIVE: The aim of this study is evaluation of vitamin D as a agent that can reduce fertility complications of chemotherapy specially in young women.
    METHODS: Breast cancer patients undergoing chemotherapy at two cancer institutes were enrolled in this study. The case group received 1000 IU of calcitriol, and the AMH level was measured at the baseline, after chemotherapy, and six months after chemotherapy. The primary end point was improvement in the AMH level after six months of chemotherapy. the secondary endpoint was to evaluate the predictive factors of AMH level decline during chemotherapy.
    RESULTS: Between 2018 and 2019, 18 and 15 patients were enrolled in the case and control groups, respectively. The mean AMH level (ngr/ml) of the patients in the case and control group were 3.16 and 2.37 ng/mL, respectively (p-value = .16). These levels were 0.387 and 0.19 after six months (p-value = .38). The AMH rise immediately after chemotherapy cycles to six months after chemotherapy, in the case and control groups were 0.86 and 0.44 ng/mL, respectively, which was slightly higher in the case group but not statistically significant between two groups (p-value = .054).
    CONCLUSIONS: Despite a minimal rise in the AMH level after six months of chemotherapy, the study could not demonstrate any protective effect of vitamin D on patients\' ovarian reserve undergoing chemotherapy for breast cancer. Further larger studies are needed to evaluate the effect of vitamin D supplements on ovarian reserve beside optimal dose and duration.

    已提出卵巢移位术(OT)作为针对辐射引起的卵巢功能和生育能力损害的保护措施。尽管它的历史用途,有限的研究集中在评估青春期之前或青春期期间在青少年和年轻人(AYAs)中进行OT后的内分泌和外分泌卵巢功能。我们研究的目的是调查生育率,青春期发育,和卵巢功能的女性在童年时期有OT的历史,青春期或年轻的成年。在一项观察性的双中心回顾性研究中,我们纳入了32例于1990年至2015年间在里昂贝拉德癌症中心或南希大学医院26岁之前接受了OT的年轻女性癌症患者.OT时的平均年龄为15.6岁,癌症诊断为15±4.8岁。在治疗后尝试怀孕的10名妇女中,60%成功怀孕。经过9.6±7年的平均随访,74%(23人中有17人)的女性恢复了自发的月经周期(8名可评估的女性中有7名在青春期之前或青春期期间患有OT)。值得注意的是,35%未尝试怀孕的妇女表现出足够的卵巢储备。接受的特定化疗会影响卵巢储备和功能恢复。重要的是,我们的研究结果表明,与青春期阶段相比,在青春期之前或期间进行OT对卵巢活动恢复的有效性没有显著差异.这项研究为接受OT的年轻女性的长期生殖结果提供了宝贵的见解,强调其在不同发育阶段保留卵巢功能和生育能力的潜在功效。
    Ovarian transposition (OT) has been proposed as a protective measure against radiation-induced damage to ovarian function and fertility. Despite its historical use, limited research has focused on evaluating endocrine and exocrine ovarian function after OT performed in adolescents and young adults (AYAs) before or during puberty. The purpose of our study was to investigate the fertility, pubertal development, and ovarian function of women with a previous history of OT during childhood, adolescence or young adulthood. In an observational bicentric retrospective study, we included 32 young female cancer patients who underwent OT before the age of 26 between 1990 and 2015 at Lyon Léon Bérard Cancer Center or Nancy University Hospital. The mean age at the time of OT was 15.6 years with a cancer diagnosis at 15 ± 4.8 years. Among the 10 women attempting pregnancy post-treatment, 60% achieved successful pregnancies. After a mean follow-up of 9.6 ± 7 years, 74% (17 out of 23) of women recovered spontaneous menstrual cycles (seven out of eight evaluable women with OT before or during puberty). Notably, 35% of women who did not attempt pregnancy demonstrated adequate ovarian reserve. Ovarian reserve and function recovery were influenced by the specific chemotherapy received. Importantly, our findings suggest that OT\'s effectiveness on ovarian activity resumption does not significantly differ when performed before or during puberty compared to pubertal stages. This study contributes valuable insights into the long-term reproductive outcomes of young women undergoing OT, emphasizing its potential efficacy in preserving ovarian function and fertility across different developmental stages.
