These studies have focused mainly on comparing pregnancy outcomes with those of other stimulation protocols. However, owing to the unique features of the PPOS-related strategy, such as its flexible timing of oocyte retrieval and repeated transfer of frozen embryos, studies using the CLBR as an overall indicator of success and investigating which types of patients would benefit from this protocol are lacking.\u0000 \u0000 \u0000 \u0000 This retrospective cohort study included 18,593 women who underwent PPOS-related protocols (dydrogesterone + hMG, medroxyprogesterone acetate + hMG, micronized progesterone + hMG treatment, and luteal-phase ovarian stimulation protocol) from 1 March 2011 to 31 September 2022 in our centre.\u0000 \u0000 \u0000 \u0000 The population was categorized by female age, number of oocytes retrieved, and AFC in the analysis of CLBR within six FET cycles. The age groups (groups 1-5, respectively) were <30, 30-34, 35-39, 40-44, and ≥45 years. The number of oocytes retrieved was grouped as 1-5, 6-10, 11-15, 16-20, and >20. AFC was grouped as < 5, 5-10, 11-15, and >15. The Kaplan–Meier analysis (optimistic method), which hypothesized that patients who did not continue treatment had the same chance of achieving a live birth as those who continued, and the competing risk method (conservative method) which hypothesized they had no chance of achieving a live birth, were applied. In further analyses, the Cox model and Fine–Gray model were adopted: the former corresponds to the optimistic scenario, and the latter corresponds to the pessimistic scenario.\u0000 \u0000 \u0000 \u0000 CLBR had a declining trend with female age over six FET cycles (groups 1-5, respectively: optimistic: 96.9%, 96.6%, 91.4%, 67.3%, and 11.7%; conservative: 87.3%, 85.0%, 74.0%, 41.3%, and 7.5%), requiring more FET cycles to achieve a success rate of at least 50% (groups 1-5, respectively: optimistic: 2, 2, 2, 4 and >6 cycles; conservative: 2, 2, 2, > 6 and > 6 cycles). CLBR showed an increasing trend with the number of oocytes retrieved (groups 1-5, respectively: optimistic: 93.8%, 94.3%, 95.8%, 96.0%, and 95.6%; conservative: 66.2%, 78.3%, 85.6%, 88.9%, and 91.0%).

Although adverse birth outcomes have been frequently reported in mothers with PCOS, such associations in the setting of a hypertensive disorder remain unknown.\u0000 \u0000 \u0000 \u0000 This is a population-based cohort study including all live births 2004-2014 in Finland (n = 652 732), excluding mothers with diagnoses that could cause signs and symptoms like PCOS to ensure diagnosis specificity.\u0000 \u0000 \u0000 \u0000 Maternal diagnoses of PCOS, gestational hypertension, chronic hypertension, and pre-eclampsia were identified from the Finnish national registries. Generalized estimating equation and multivariable logistic regression were used to assess the adjusted odds ratio (aOR) and 95% CIs of preterm birth, very preterm birth and offspring being small (SGA) or large (LGA) for gestational age in hypertensive mothers with or without PCOS, using normotensive mothers without PCOS as reference.\u0000 \u0000 \u0000 \u0000 Of 43 902 (6.7%) mothers with hypertensive disorders, 1709 (3.9%) had PCOS.

Using mothers with no hypertensive disorder and no PCOS as reference, the risks of preterm and very preterm birth were overrepresented in mothers with chronic hypertension and pre-eclampsia without PCOS. PCOS was associated with higher risks of preterm birth (aOR PCOS 4.02, 3.14–5.15 vs. aOR non-PCOS 2.51, 2.32–2.71) in mothers with chronic hypertension, with significant interaction between the exposures (F = 32.7, pinteraction <0.001). Comorbid PCOS was also associated with a higher risk of preterm birth in singleton pregnancies of mothers with pre-eclampsia (aOR PCOS 7.33, 5.92–9.06 vs. aOR non-PCOS 5.72, 5.43–6.03; F = 50.0, pinteraction<0.001). Furthermore, the combined associations of PCOS with chronic hypertension or pre-eclampsia persisted for spontaneous births. Moreover, the risk of offspring LGA was increased in mothers with PCOS and gestational hypertension although decreased in those with gestational hypertension alone (aOR PCOS 2.04, 1.48–2.80 vs. aOR non-PCOS 0.80, 0.72–0.89; F = 9.7, pinteraction=0.002), whereas for offspring SGA the risks were comparable between hypertensive mothers with and those without PCOS.\u0000 \u0000 \u0000 \u0000 Information on medication treatment, gestational weeks of onset for pre-eclampsia and gesta","PeriodicalId":73264,"journal":{"name":"Human reproduction open","volume":"58 13","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138604961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although a vascular origin has been postulated, heterozygous missense variants in DHX37 have been attributed to the phenotype as well. How these various etiologies impact the clinical phenotype, gonadal histology and outcome of BTR remains unclear.\u0000 \u0000 \u0000 \u0000 For this cross-sectional study, individuals with BTR were recruited in eight Belgian pediatric endocrinology departments, between December 2019 and December 2022. A physical exam was performed cross-sectionally in all 17 end-pubertal participants and a quality of care questionnaire was completed by 11 of them. Exome-based panel testing of 241 genes involved in gonadal development and spermatogenesis was performed along with a retrospective analysis of presentation and management. A centralized histological review of gonadal rests was done for 10 participants.\u0000 \u0000 \u0000 \u0000 A total of 35 participants (33 with male, one with female and one with non-binary gender identity), were recruited at a mean age of 15.0±5.7 years.\u0000 \u0000 \u0000 \u0000 The median age at presentation was 1.2 years [0-14 years]. Maternal gestational complications were common (38.2%), with a notably high incidence of monozygotic twin pregnancies (8.8%). Heterozygous (likely) pathogenic missense variants in DHX37 (p.Arg334Trp and p.Arg308Gln) were found in three participants. No other (likely) pathogenic variants were found. All three participants with a DHX37 variant had a microphallus at birth (leading to female sex assignment in one), while only six of the remaining 31 participants without a DHX37 variant (19.4%) had a microphallus at birth (information regarding one participant was missing). Testosterone therapy during infancy to increase penile growth was more effective in those without versus those with a DHX37 variant. The three participants with a DHX37 variant developed a male, female and non-binary gender identity, respectively; all other participants identified as males. Testosterone replacement therapy (TRT) in incremental doses had been initiated in 25 participants (median age at start 12.4 years). Final height was within the target height range in all end-pubertal participants, however, five out of 11 participants (45.5%), for whom stretched penile length (SPL) was measured, had a micropenis (mean adult SPL: 9.6 ± 2.5). Of the 11 participants who completed the questionnaire, five (45.5%) reported suboptimal understanding of the goals and effects of TRT at the time of puberty induction.

Indeed, different types of adult and fetal mesenchymal stem cells (MSCs) have been tested with promising results, owing to their ability to differentiate into different tissue lineages, move toward specific injured sites (homing), and generate a secretome with wound-healing, proangiogenic, and antioxidant capacities.</p><p><strong>Study design size duration: </strong>Guided by the checklist for preferred reporting items for systematic reviews and meta-analyses, we retrieved relevant studies from PubMed, Medline, and Embase databases until June 2023 using the following keywords: 'mesenchymal stem cells' AND 'ovarian follicles' OR 'ovarian tissue culture' OR 'ovarian follicle culture' OR 'cumulus oocyte complex'. Only peer-reviewed published articles written in English were included.</p><p><strong>Participants/materials setting methods: </strong>The primary outcome for the experimental strategies was evaluation of the ovarian reserve, with a focus on follicle survival, number, and growth. Secondary outcomes involved analyses of other parameters associated with the follicle pool, such as hormones and growth factors, ovarian tissue viability markers including oxidative stress levels, oocyte growth and maturation rates, and of course pregnancy outcomes.</p><p><strong>Main results and the role of chance: </strong>Preclinical studies exploring MSCs from different animal origins and tissue sources in specific conditions were selected (n = 112), including: <i>in vitro</i> culture of granulosa cells, ovarian tissue and isolated ovarian follicles; ovarian tissue transplantation; and systemic or intraovarian injection after gonadotoxic or age-related follicle pool decline. Protecting the ovarian reserve from aging and gonadotoxic damage has been widely tested <i>in vitro</i> and <i>in vivo</i> using murine models and is now yielding initial data in the first ever case series of patients with premature ovarian insufficiency. Use of MSCs as feeder cells in ovarian tissue culture was found to improve follicle outcomes and oocyte competence, bringing us one step closer to future clinical application. MSCs also have proved effective at boosting revascularization in the transplantation site when grafting ovarian tissue in experimental animal models.</p><p><strong>Limitations reasons for caution: </strong>While preclinical results look promising in te","PeriodicalId":73264,"journal":{"name":"Human reproduction open","volume":"2023 4","pages":"hoad040"},"PeriodicalIF":0.0,"publicationDate":"2023-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10637864/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89720958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
