Abstract
One of the initial causes of cystic ovarian disease (COD) is a failure in the normal ovulation mechanism. This study aimed to characterize the populations of immune cells (T-lymphocytes, B-lymphocytes, monocytes-macrophages and granulocytes) present in the ovary of cows with COD and induced follicular persistence, and evaluate their relation with follicular persistence and cyst formation. The follicular persistence model was developed using a progesterone (P4) slow-release intravaginal device, to obtain subluteal concentrations of P4. Results evidenced that T-lymphocytes, B-lymphocytes and monocytes-macrophages in the cortex, medulla, and theca externa and interna of dominant follicles were higher in the control group than in the COD and all persistence groups. Granulocytes in the medulla and theca externa of dominant follicles were lower in the control group than in the COD group, and those in the cortex and medulla were lower in the control group than in the persistence groups. The presence of T-lymphocytes, B-lymphocytes and granulocytes in the follicular fluid was abundant, especially that of granulocytes, without differences between control and COD cows. These results suggest that the immune system potentially plays a role in the local mechanisms of COD pathogenesis in dairy cows. In spontaneous COD and in our follicular persistence model, the distribution of the cells studied was different from that in the control group. However, to our knowledge, this is the first report describing the presence of immune cells in bovine follicular fluid samples and the expression of steroid hormone receptors in infiltrating immune cells in the bovine ovary.

Abstract
Ovarian endometrioma (OE) is a common gynecological condition characterized by the formation of "chocolate cysts". Recent research indicates that the cyst fluid acts as a "toxic environment" for the ovary and plays a significant role in the development of OE, with macrophages being pivotal. However, the specific molecular and cellular mechanisms of it are not fully understood. In this study, clinical samples are integrated, single-cell sequencing, in vivo and in vitro experimental models to comprehensively investigate the effects of OE fluid on ovarian function and the mechanisms of it. Combined with bioinformatics analysis and experimental validation, the findings demonstrate that OE fluid can cause ovarian function decline, which associated with inflammatory response, and mitochondrial dysfunction and cellular senescence, while activating the cGAS/STING signaling pathway. As a STING inhibitor, H-151 effectively alleviates ovarian dysfunction, inflammatory state and cell apoptosis induced by OE fluid. Furthermore, it is also discovered that H-151 can inhibit OE fluid-induced mitochondrial dysfunction and cellular senescence. These findings provide important theoretical and experimental foundations for further research and development of STING inhibitors as potential drugs for treating ovarian dysfunction.

Abstract
OBJECTIVE To evaluate the effect of SARS-CoV-2 infection and vaccination on ovarian reserve. METHODS Relevant articles were identified in the EMBASE, PubMed, and Web of Science databases from January 2020 to May 2023. Available clinical indicators of ovarian reserve, such as anti-Müllerian hormone (AMH), antral follicle count (AFC), follicle-stimulating hormone (FSH), and estradiol (E2), as well as the time interval from infection or vaccination to measurements, were assessed. RESULTS Only 2 studies provided evidence that SARS-CoV-2 infection could damage ovarian function. In a comparison of the vaccinated and unvaccinated groups, although 1 prospective cohort study observed the transient statistically significant decrease on serum AMH levels at 3 or 6 months of follow-up, serum AMH levels remained within the normal reserve range (>1.1 ng/dl) throughout the study period. CONCLUSION Overall, whether ovarian reserve may be affected by SARS-CoV-2 infection remains controversial and further investigations are warranted to clarify this issue. Based on the current evidence, it is safe to assume that COVID-19 vaccination does not exert any adverse effect on ovarian reserve parameters such as AMH, AFC, FSH, and E2, which will provide reassurance for women attempting to fall pregnant.

Abstract
Endometriosis is a hormone-dependent disease associated with impaired immunoregulation. In our recent study, we have characterized the trascriptomic transformation of eutopic endometrium from patients with minimal/mild endometriosis and controls across the menstrual cycle. However, the regulatory mechanism of altered immune microenvironment in eutopic endometrial stromal cells (ESCs) remains unclear. Here, we want to explore the regulation of immune cell to progesterone resistance and endometrial receptivity in the eutopic ESCs by cytokine (TGF-β1), and to understand the effect of TGF-β1 on the decidualization of the eutopic ESCs. Primary culture of eutopic ESCs was performed to explore the effects of TGF-β1 on the expression of Smad and progesterone receptor (PR) and the in vitro decidualization. Additionally, co-immunoprecipitation (Co-IP) was used to explore the direct interaction between Smad and PR. We found an attenuate expression of PRB protein (p=0.026) after using TGF-β1 in eutopic ESCs, although the difference of PRA before and after treatment was not significant (p=0.678). Similarly, the results of qRT-PCR showed that the mRNA level of PR (p<0.001), PRB (p=0.003) and HOXA10 (p<0.001) decreased significantly after TGF-β1 treatment, but that increased (p<0.023, for all) after SB431542 treatment in the eutopic ESCs. Moreover, TGF-β1 has a negative effect on the in vitro decidualization of eutopic ESCs (p=0.003). And the group with treatment of both TGF-β1 and SB435142 in eutopic ESCs showed significant decidual-like changes with increased prolactin level (p=0.01). We did not observe any physical interaction between the PR and p-Smad3/Smad3 proteins by using Co-IP. By activating TGF-β/Smad signaling in eutopic ESCs, elevated TGF-β1 from CD45+ immune cells could attenuate expression of PR, and further decrease endometrial receptivity.

Abstract
Association studies investigating miRNA in relation to diseases have consistently shown significant alterations in miRNA expression, particularly within inflammatory pathways, where they regulate inflammatory cytokines, transcription factors (such as NF-κB, STAT3, HIF1α), and inflammatory proteins (including COX-2 and iNOS). Given that endometriosis (EMS) is characterized as an inflammatory disease, albeit one influenced by estrogen levels, it is natural to speculate about the connection between EMS and miRNA. Recent research has indeed confirmed alterations in the expression levels of numerous microRNAs (miRNAs) in both endometriotic lesions and the eutopic endometrium of women with EMS, when compared to healthy controls. The undeniable association of miRNAs with EMS hints at the emergence of a new era in the study of miRNA in the context of EMS. This article reviews the advancements made in understanding the pathological role of miRNA in EMS and its association with EMS-associated infertility. These findings contribute to the ongoing pursuit of developing miRNA-based therapeutics and diagnostic markers for EMS.

Immune Checkpoints in Recurrent Pregnancy Loss: New Insights into a Detrimental and Elusive Disorder. Int J Mol Sci 2023; 24:13071.

Abstract
Recurrent pregnancy loss (RPL) refers to two or more miscarriages before 20 weeks gestation. Its prevalence is 1-2%; its pathogenesis remains unexplained in more than 50% of cases, in which the cause is thought to be abnormal immune activity during placentation leading to a lack of pregnancy-induced immune tolerance. It is unknown whether immune activity is deranged in the endometrium of women with RPL. We studied the gene expression and the quantitative tissue protein levels of three immune checkpoints (CD276, which enhances cytotoxic T-cell activity, cytotoxic T-lymphocyte-associated antigen-4 [CTL-4], which reduces Th1 cytokine production, and lymphocyte activation gene-3 [LAG-3], which shows suppressive activity on Tregs and CD4+ T-cells) in endometrial samples from 27 women with unexplained RPL and in 29 women with dysfunctional uterine bleeding and previous uneventful pregnancies as controls. RNA isolation, real-time PCR, protein isolation, and ELISA were performed. CD276 gene expression and protein tissue levels were significantly lower in the endometrium of the RPL group than in the controls, whereas both CTL-4 and LAG-3 were significantly higher. This difference suggests defective endometrial immune regulation and overactivation of immune response in women with a history of RPL, at least in relation to controls with dysfunctional uterine bleeding and previous normal reproductive history.

Abstract
BACKGROUND Endometriosis, a common oestrogen-dependent inflammatory disorder in women of reproductive age, is characterized by endometrial-like tissue outside its normal location in the uterus, which causes pelvic scarring, pain and infertility. While its pathogenesis is poorly understood, the immune system (systemically and locally in endometrium, pelvic endometriotic lesions and peritoneal fluid) is believed to play a central role in its aetiology, pathophysiology and associated morbidities of pain, infertility and poor pregnancy outcomes. However, immune cell populations within the endometrium of women with the disease have had incomplete phenotyping, thereby limiting insight into their roles in this disorder. OBJECTIVE AND RATIONALE The objective herein was to determine reproducible and consistent findings regarding specific immune cell populations and their abundance, steroid hormone responsiveness, functionality, activation states, and markers, locally and systemically in women with and without endometriosis. SEARCH METHODS A comprehensive English language PubMed, Medline and Google Scholar search was conducted with key search terms that included endometriosis, inflammation, human eutopic/ectopic endometrium, immune cells, immune population, immune system, macrophages, dendritic cells (DC), natural killer cells, mast cells, eosinophils, neutrophils, B cells and T cells. OUTCOMES In women with endometriosis compared to those without endometriosis, some endometrial immune cells display similar cycle-phase variation, whereas macrophages (Mø), immature DC and regulatory T cells behave differently. A pro-inflammatory Mø1 phenotype versus anti-inflammatory Mø2 phenotype predominates and natural killer cells display abnormal activity in endometrium of women with the disease. Conflicting data largely derive from small studies, variably defined hormonal milieu and different experimental approaches and technologies. WIDER IMPLICATIONS Phenotyping immune cell subtypes is essential to determine the role of the endometrial immune niche in pregnancy and endometrial homeostasis normally and in women with poor reproductive history and can facilitate development of innovative diagnostics and therapeutics for associated symptoms and compromised reproductive outcomes.

Endometriosis, especially mild disease: a risk factor for miscarriages. Fertil Steril 2017; 108:806-814.e2. [PMID: 29079275 DOI: 10.1016/j.fertnstert.2017.08.025] [Citation(s) in RCA: 31] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2017] [Revised: 08/07/2017] [Accepted: 08/14/2017] [Indexed: 12/15/2022]
Abstract
OBJECTIVE To investigate the prevalence of miscarriage in women with endometriosis (WwE) compared with disease-free control women (CW). DESIGN Cross-sectional analysis nested in a retrospective observational study (n = 940). SETTING Hospitals and associated private practices. PATIENT(S) Previously pregnant women (n = 268) within reproductive age in matched pairs. INTERVENTION(S) Retrospective analysis of surgical reports and self-administered questionnaires. MAIN OUTCOME MEASURE(S) Rate of miscarriage, subanalysis for fertility status (≤12 vs. >12 months' time to conception), endometriosis stages (revised American Society of Reproductive Medicine classification [rASRM] I/II vs. III/IV) and phenotypic localizations (superficial peritoneal, ovarian, and deep infiltrating endometriosis). RESULT(S) The miscarriage rate was higher in WwE (35.8% [95% confidence interval 29.6%-42.0%]) compared with CW (22.0% [16.7%-27.0%]); adjusted incidence risk ratio of 1.97 (95% CI 1.41-2.75). This remained significant in subfertile WwE (50.0% [40.7%-59.4%]) vs. CW (25.8% [8.5%-41.2%]) but not in fertile WwE (24.5% [16.3%-31.6%]) vs. CW (21.5% [15.9%-26.8%]). The miscarriage rate was higher in women with milder forms (rASRM I/II 42.1% [32.6%-51.4%] vs. rASRM III/IV 30.8% [22.6%-38.7%], compared with 22.0% [16.7%-27.0%] in CW), and in women with superficial peritoneal endometriosis (42.0% [32.0%-53.9%]) compared with ovarian endometriosis (28.6% [17.7%-38.7%]) and deep infiltrating endometriosis (33.9% [21.2%-46.0%]) compared with CW (22.0% [16.7%-27.0%]). CONCLUSION(S) Mild endometriosis, as in superficial lesions, is related to a great extent of inflammatory disorder, possibly leading to defective folliculogenesis, fertilization, and/or implantation, presenting as increased risk of miscarriage. CLINICAL TRIAL REGISTRATION NUMBER NCT02511626.

Gonadotrophin stimulation in IVF alters the immune cell profile in follicular fluid and the cytokine concentrations in follicular fluid and serum. Hum Reprod 2017; 32:820-831.

Abstract
Study question Are the immune cell profiles and the cytokine concentrations in follicular fluid (FF) and serum at the preovulatory stage different in conventional exogenous gonadotrophin stimulated IVF (c-IVF) compared with natural cycle IVF (NC-IVF)? Summary answer The cell counts of CD45+ leucocytes and T cell subpopulations and the cytokine concentrations in FF and serum are different in c-IVF compared to NC-IVF. What is known already FF-derived cells are heterogeneous. Immune cells are involved in intra-ovarian processes and cytokines are required for normal follicular development. Gonadotrophins stimulate the regulatory intrafollicular system and influence the local distribution of immune cells and the intrafollicular release of cytokines. Administration of exogenous gonadotrophins may have a significant effect on this local regulatory system, which then in turn could influence oocyte quality. Study design, size, duration The study included 105 patients, 69 undergoing c-IVF and 36 undergoing NC-IVF. c-IVF was performed by exogenous ovarian stimulation with hMG and GnRH antagonists. Participants/materials, setting, methods FF samples were collected from the first dominant follicle in c-IVF without pooling and from single leading preovulatory follicles in NC-IVF. Three different approaches were used to analyze FF samples: (i) microscopic investigation of CD45+ leucocytes, (ii) fluorescence-activated cell sorting to determine CD19+ B cells and CD3+ T cells including T cell subpopulations (CD4+, CD8+), and (iii) evaluation of tumour necrosis factor-alpha (TNF-α), interferon-gamma (INF-γ), interleukins (IL)-2, -6, -8, -10 and vascular endothelial growth factor (VEGF) levels in matched FF and serum samples using the Bio-Plex® platform. Main results and the role of chance FF obtained from c-IVF contained proportionally more CD45+ leucocytes (P = 0.0384), but fewer CD8+ cytotoxic T cells than FF from NC-IVF. CD3+ T lymphocytes were the most common type of lymphocytes, and the number thereof was comparable in the two study groups. In c-IVF, serum VEGF levels were higher (P = 0.007) than in NC-IVF while FF contained marginally decreased concentrations of IL-8 in c-IVF in comparison to NC-IVF. The cytokine concentration gradient between FF and serum in c-IVF was 10-fold for IL-8 and 8-fold for VEGF and thereby markedly lower than in NC-IVF, where the differences were 32-fold and 30-fold, respectively. Strong positive correlations were determined between FF- IL-10 and FF- VEGF in c-IVF (r = 0.85, P < 0.0001) and in NC-IVF (r = 0.81, P < 0.0001). Large scale data N/A. Limitations, reasons for caution The ovulation of NC-IVF follicles was induced by the exogenous administration of hCG, which means that the environment did not fully correspond to the physiological situation. Wider implications of the findings The differences in the immune profile and the cytokine concentrations in c-IVF and NC-IVF follicles support the hypothesis that conventional ovarian stimulation affects indirectly and heterogeneously the intrafollicular milieu, and thereby possibly affects the oocyte quality and the IVF outcome. However, further studies are needed to confirm our findings and to refine stimulation protocols in the context of optimizing the intrafollicular environment during oocyte maturation. Study funding/competing interest(s) The study was supported by a research grant from IBSA Institut Biochimique SA and MSD Merck Sharp & Dohme GmbH. The authors are clinically involved in low dose mono-follicular stimulation and IVF-therapies, using gonadotrophins from all gonadotrophins distributors on the Swiss market, including Institut Biochimique SA and MSD Merck Sharp & Dohme GmbH.

Abstract
The physiopathology of endometriosis is not completely understood and its progression is associated with a local and systemic inflammatory reaction. It is important to clarify the potential role of the immune system to better understand its implication in the pathogenesis of endometriosis, which includes the study of the role of B cells and antibodies. The aim of this study was to review the literature about the role of B lymphocytes in endometriosis. A search for "endometriosis", "B cells" and "B lymphocytes" in databases resulted in 140 citations; after applying inclusion and exclusion criteria, a total of 22 studies were assessed. The analyzed samples in the studies varied and different markers and techniques were used by the authors to evaluate the direct or indirect role of B lymphocytes in endometriosis. Most studies demonstrated increased number and/or activation of B cells while seven studies found no difference and two studies showed decreased number of B cells. Increased B lymphocytes and excessive production of autoantibodies in endometriosis have been described in the literature, but their role in the development of the disease is not well understood. Moreover, the association of these factors with clinical symptoms, location and severity of the disease has not been investigated. Further studies are necessary to clarify the role of B cells in the development of endometriosis and propose new therapeutic strategies such as the use of drugs that target these cells.

Abstract
OBJECTIVE To determine whether endometriosis ultimately results in an increased risk of embryonic aneuploidy. DESIGN Retrospective cohort. SETTING Infertility clinic. PATIENT(S) Patients participating in an in vitro fertilization (IVF) cycle from 2009-2015 using preimplantation genetic screening (PGS) who had endometriosis identified by surgical diagnosis or by ultrasound findings consistent with a persistent space-occupying disease whose sonographic appearance was consistent with endometriosis. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Rate of aneuploidy in endometriosis patients undergoing IVF compared to controls without endometriosis undergoing IVF. RESULT(S) There were 305 patients with endometriosis who produced 1,880 blastocysts that met the criteria for inclusion in the endometriosis group. The mean age of the patients with endometriosis was 36.1 ± 3.9 years. When the aneuploidy rates in patients with endometriosis and aneuploidy rates in patients without endometriosis were stratified by Society for Assisted Reproductive Technology age groups and compared, there were no statistically significant differences in the rate of aneuploidy (odds ratio 0.85; 95% confidence interval, 0.84-0.85). CONCLUSION(S) Patients with endometriosis undergoing IVF have aneuploidy rates equivalent to their age-matched peers in IVF population who do not have endometriosis.

Abstract
OBJECTIVE To investigate immunologic parameters and endoplasmic reticulum (ER) stress associated with unexplained infertility. DESIGN Case-control study. SETTING Academic center. PATIENT(S) Women with no fertility problems (FS) (n = 13), women with recurrent miscarriage (RM) (n = 15) and women with repeated in vitro fertilization failure (RIF) (n = 15). INTERVENTION(S) Endometrial biopsy and collection of peripheral blood during the midsecretory phase of menstrual cycle. MAIN OUTCOME MEASURE(S) Leptin, resistin, soluble tumor necrosis factor receptor (sTNF-R), myeloperoxidase (MPO), soluble intercellular adhesion molecule 1 (sICAM-1), and interleukin 22 (IL-22) concentration in peripheral blood, endometrial CD3(+), CD4(+), CD5(+), CD8(+), and FoxP3(+) T lymphocytes, and endometrial expression of HSPA5, a specific marker of ER stress. RESULT(S) We found an increase of proinflammatory molecules such as resistin, leptin, and IL-22 in both RM and RIF patients; sTNF-R and MPO only in RIF patients when compared with the FS women. We also found in endometria of infertile women a statistically significant increase of CD3(+), CD4(+), CD8(+) in both RM and RIF patients and CD5(+) in RM patients when compared with FS women. This was paralleled by a statistically significant reduction of infiltrating FoxP3(+) regulatory T cells. Finally, endometrial HSPA5 expression levels were statistically significantly up-regulated in both RM and RIF patients. CONCLUSION(S) Women with RM and RIF showed an increase of circulating proinflammatory cytokines, altered endometrial T lymphocytes subsets, and signs of endometrial ER stress.

Inducers of G-protein coupled estrogen receptor (GPER) in endometriosis: potential implications for macrophages and follicle maturation. J Reprod Immunol 2013; 97:95-103.

Abstract
Endometriosis is an estrogen dependent chronic inflammation and thus a condition of stress. Though the G-protein coupled estrogen receptor (GPER) has been shown to be up-regulated in ovarian endometriosis, insights involved in inducing this receptor expression are largely elusive. Therefore, this study investigated whether stress-related factors (ACTH, prednisolone) or inflammatory factors (IL-1β, TNFα, and PGE(2)) factors may affect GPER. To further link GPER to endometriosis pathophysiology it was tracked in macrophages and follicles of endometriotic ovaries. This study found GPER expression to be modulated by stress-related hormones as well as inflammation and to be up-regulated in endometriosis-associated macrophages. At the same time, follicles of ovaries affected by endometriosis presented significantly reduced GPER positivity when compared to controls, suggesting a possible way by which endometriosis may affect folliculogenesis. The multiple roles of GPER as presented herein make it a promising future candidate for targeted molecular endometriosis treatment.

Abstract
Endometriosis is a gynecological disease characterized by the presence of endometrial glandular epithelial and stromal cells growing in the extra-uterine environment. The disease afflicts 10%–15% of menstruating women causing debilitating pain and infertility. Endometriosis appears to affect every part of a woman’s reproductive system including ovarian function, oocyte quality, embryo development and implantation, uterine function and the endocrine system choreographing the reproductive process and results in infertility or spontaneous pregnancy loss. Current treatments are laden with menopausal-like side effects and many cause cessation or chemical alteration of the reproductive cycle, neither of which is conducive to achieving a pregnancy. However, despite the prevalence, physical and psychological tolls and health care costs, a cure for endometriosis has not yet been found. We hypothesize that endometriosis causes infertility via multifaceted mechanisms that are intricately interwoven thereby contributing to our lack of understanding of this disease process. Identifying and understanding the cellular and molecular mechanisms responsible for endometriosis-associated infertility might help unravel the confounding multiplicities of infertility and provide insights into novel therapeutic approaches and potentially curative treatments for endometriosis.

Abstract
OBJECTIVE To retrospectively analyze the effects of long-acting gonadotropin-releasing hormone agonist (GnRH-a) combined with transvaginal ultrasound-guided cyst aspiration on the pregnancy outcomes of in vitro fertilization-embryo transfer (IVF-ET) in the infertile patients with ovarian endometriosis. METHODS The 134 patients with ovarian endometriosis who underwent GnRH-a combined with transvaginal ultrasound-guided cyst aspiration and IVF-ET were served as experimental group. The 102 patients with ovarian endometriosis who underwent GnRH-a and IVF-ET were served as control group. After treatment, the cyst size, follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), number of ovum pick-up, fertility rate, cleavage rate, high-quality embryo rate, implantation rate, clinical pregnancy rate and abortion rate were compared between the two groups. RESULTS In the 134 patients of experimental group, 138 cysts disappeared after GnRH-a combined with three times of transvaginal ultrasound-guided cyst aspiration. In the 102 patients of control group, of the 114 cysts, 34 disappeared after GnRH-a, 67 were decreased and 13 were unchanged. The abortion rate was significantly lower in experimental group than in control group. The level of serum E2 on HCG day, the number of ovarian follicles with 14 mm or more, the number of retrieved oocytes, high-quality embryo rate, implantation rate and clinical pregnancy rate were higher in experimental group than in control group (all P<0.05). CONCLUSION GnRH-a combined with transvaginal ultrasound-guided cyst aspiration can obtain better therapeutic effects and pregnancy outcomes in infertile patients with ovarian endometriosis who underwent IVF-ET.

Abstract
Background Although Tim-3 & PD-L1 signaling pathways play important roles in negatively regulating immune responses, their roles in chlamydial infection have not been evaluated. Methods Neutralization antibodies targeting Tim-3 and PD-L1 were used to treat mice. Following an intravaginal infection with C. muridarum organisms, mice with or without the dual antibody treatment were compared for live chlamydial organism shedding from the lower genital tract and inflammatory pathology in the upper genital tract. Results Mice treated with anti-Tim-3 and anti-PD-L1 antibodies displayed a time course of live organism shedding similar to that of mice treated with equivalent amounts of isotype-matched IgG molecules. The combined antibody blocking failed to alter either the lower genital tract cytokine or systemic humoral and cellular adaptive responses to C. muridarum infection. However, the antibody blocking significantly enhanced C. muridarum-induced pathologies in the upper genital tract, including more significant hydrosalpinx and inflammatory infiltration in uterine horn and oviduct tissues. Conclusions The Tim-3 and PD-L1-mediated signaling can significantly reduce pathologies in the upper genital tract without suppressing immunity against chlamydial infection, suggesting that Tim-3 and PD-L1-mediated negative regulation may be manipulated to attenuate tubal pathologies in women persistently infected with C. trachomatis organisms.

Abstract
We investigated effects of multivitamin/mineral supplementation on element levels in serum and follicular fluid of women undergoing IVF. We used three groups in this study. The first group was used as an age-matched and nonpregnant control (n = 13). Group 2 (n = 30) constituted the IVF group and women in the third group who were undergoing IVF also received a multivitamin/mineral tablet daily for 45 days. Follicular fluid and serum selenium and zinc levels and follicular fluid copper levels were lower in IVF patients than in controls although follicular fluid aluminum and iron levels were higher in IVF patients than in controls. However, follicular fluid and serum aluminum, copper, zinc and selenium levels, and serum magnesium levels were higher in the multivitamin/mineral group than in the IVF group although follicular fluid iron levels were lower in the multivitamin/mineral group than in the IVF group. In conclusion, we observed that copper, zinc, and selenium in serum and follicular fluid decreased in women undergoing IVF. Multivitamin/mineral supplementation in serum and follicular fluid of women undergoing IVF normalized the trace element levels.

Abstract
Endometriosis is regarded as a complex trait, in which genetic and environmental factors contribute to the disease phenotype. We investigated whether the interleukin (IL) 1beta (+3953) polymorphism is associated with the severity of endometriosis. Diagnosis of endometriosis was made on the basis of laparoscopic findings. Stage of endometriosis was determined according to the Revised American Fertility Society classification. 118 women were enrolled in the study. 78 women did not have endometriosis, 6 women had stage I, 3 had stage II, 13 had stage III and 18 had stage IV endometriosis. Polymerase Chain Reaction (PCR), Restriction Fragment Length Polymorphism (RFLP), and agarose gel electrophoresis techniques were used to determine the IL 1beta (+3953) genotype. Frequencies of the IL-1beta (+3953) genotypes in the control group were: CC, 0.397; TT, 0.115; CT, 0.487. Frequencies of the IL-1beta (+3953) genotypes in cases were: CC, 0.375; TT, 0.225; CT, 0.400. We found a 2.22 fold increase in TT genotype in the endometriosis group. However, the difference was not statistically significant (P > 0.05). We also observed an increase in the frequency of IL-1beta (+3953) T allele in the endometriosis group. However, the difference was not statistically significant. We also investigated the association between IL-1beta (+3953) polymorphism and the severity of endometriosis. The frequencies of CC+CT genotypes in stage I, III and IV endometriosis patients were 83.3, 84/6 and 72.2%, respectively; and TT genotypes were 16.7, 15.4 and 27.8%, respectively. We observed a statistically insignificant increase in TT genotype in stage IV endometriosis (P > 0.05). We suggest that IL-1beta (+3953) polymorphism is not associated with endometriosis in Turkish women.

Abstract
PROBLEM Macrophage migration inhibitory factor (MIF), a potent immuno-modulatory, angiogenic and tissue remodeling factor, is markedly expressed in ectopic endometrial implants and may play key role in the capability of this tissue to grow and develop into the host tissue. The objective of this study was to determine whether macrophage-derived cytokines, such as interleukin (IL)-1, which is overproduced by endometriosis women's peritoneal macrophages and found in elevated concentration in their peritoneal fluid, may play a role in MIF synthesis and secretion by ectopic endometrial cells. METHODS OF STUDY Primary cultures of endometriotic cells exposed to IL-1beta and evaluation of MIF protein by immunocytofluorescence and ELISA, and mRNA by quantitative real-time PCR and nuclear transcription assays (run-on). RESULTS Interleukin-1beta acts rapidly on endometriotic cells and stimulated MIF secretion and mRNA steady-state levels in a dose and time-dependent manner. IL-1beta treatment had no significant effect on MIF mRNA half-life and stability, but acted predominantly by up-regulating MIF gene transcription as assessed by run-on. CONCLUSION These data clearly indicate that IL-1 can be involved in the up-regulation of MIF expression by ectopic endometrial implants. Such an interaction between IL-1 and MIF may have an important impact on endometriotic cell growth and endometriosis pathophysiology.

Abstract
BACKGROUND Cells isolated from the periovulatory ovarian follicle are often used as a model of ovarian steroidogenesis and corpus luteum formation. The follicular fluid-derived cell (FFDC) population is, however, heterogeneous and in addition to granulosa-lutein cells, non-steroidogenic cells are also present. These non-steroidogenic cells, especially the immune cells, may have important biological functions in this model. Here, we describe a method to isolate FFDC, characterize the phenotype of the immune cells and deplete immune cells from FFDC. METHODS AND RESULTS Follicular fluid aspirated transvaginally during IVF was clarified by centrifugation and enzymatic dispersion, labelled for leukocyte-specific markers and analysed by flow cytometry. Leukocytes constituted 22% of FFDC and expressed macrophage/dendritic cell, monocyte and lymphocyte markers. Leukocytes were depleted with anti-CD45-conjugated immunobeads, resulting in an FFDC population with <1.9% leukocytes. Leukocyte-containing FFDC secreted more interleukin-8 in culture than leukocyte-depleted FFDC. CONCLUSION Leukocyte-depleted FFDC may serve as a useful model to study the interaction of immune cells and luteinizing cells during corpus luteum formation.

Abstract
OBJECTIVE To compare the amount of regulated upon activation, normal T cell expressed and secreted (RANTES) and monocyte chemotactic protein 1 (MCP-1) in follicular fluid (FF) of patients with and without endometriosis and to determine their oocyte fertilization and pregnancy rates. DESIGN Case-control study. SETTING Department of Obstetrics and Gynecology, University Hospital Schleswig-Holstein, Campus Luebeck, Germany. PATIENT(S) Thirty-two women with endometriosis stages I-IV and 28 women without endometriosis, both groups surgically and histologically confirmed. INTERVENTION(S) Diagnostic laparoscopy, IVF-ET. MAIN OUTCOME MEASURE(S) RANTES and MCP-1 levels in follicular fluid, measured by ELISA, and oocyte fertilization and pregnancy rates. RESULT(S) Follicular response and days of gonadotropin stimulation were similar between the two groups. The levels of RANTES in FF from patients with endometriosis were significantly higher (460.4 +/- 90.3 pg/mL) compared with concentrations in patients with tubal infertility (243.8 +/- 70.9 pg/mL; P<.05). In contrast, MCP-1 concentrations in FF from women with endometriosis (330.0 +/- 29.2 pg/mL) were lower than in women with tubal infertility (420.5 +/- 46.6 pg/mL; P<.05). Oocyte fertilization rates in the endometriosis group (54%) were significantly lower than those of the tubal infertility group (73%; P<.05), as were the pregnancy rates (19% vs. 35%, respectively; P<.01). CONCLUSION(S) Women with endometriosis-associated infertility have a poor IVF outcome. Immune cell recruitment into the ovary might affect follicular function and lead to impaired oocyte quality.

Abstract
Human follicular fluid can provide a source of human granulosa cells for scientific study. However, removing potentially contaminating cells, such as white and red blood cells, is important for molecular and in vitro studies. We have developed a purification technique for human granulosa cells based on the selection of cellular aggregates. Human granulosa cells from 21 IVF patients were collected. A 50% Percoll gradient was used to remove red blood cells, and granulosa cell aggregates were collected, washed and processed for histology, electron microscopy, flow cytometry analysis, cell culture and RNA extraction. Granulosa cell aggregates were found to be homogeneous and free of white blood cells after histological and electron microscopic analysis. White blood cell contamination, measured by flow cytometry, was found to be between 2 and 4%. Polymerase chain reaction analysis revealed expression of known human granulosa cell genes and a white blood cell marker. Human granulosa cells grown in vitro showed flattened fibroblast-like morphology with lipid droplets consistent with previous reports. Cultured cells expressed the FSH receptor. Selection of human granulosa cell aggregates following centrifugation through a Percoll gradient provides an efficient method of selecting granulosa cells, suitable for both molecular and in vitro studies.

Abstract
Endometriosis is more frequently diagnosed in patients with infertility than in a normal population. The goal of this paper is to give an overview of the clinical and fundamental evidence for a possible link between endometriosis and (recurrent) miscarriage or implantation failure after treatment with assisted reproductive technology. According to the literature, there is insufficient evidence for an association between endometriosis and (recurrent) miscarriage, but there is, however, epidemiological evidence to support the link between endometriosis and recurrent implantation failure after assisted reproduction. This can possibly be explained by alterations in humoral and cell-mediated immunity in women with endometriosis. Humoral immunological changes include increased formation of antibodies against endometrial antigens, anti-laminin-1 auto-antibodies and other auto-immune antibodies (e.g. antiphospholipid). Cell-mediated immunological changes include alterations in peritoneal and follicular fluid immune cells and cytokines. The possible negative effect of these immunological changes on folliculogenesis, ovulation, oocyte quality, early embryonic development and implantation in women with endometriosis suggests that infertility in endometriosis patients may be related to alterations within the follicle or oocyte, resulting in embryos with decreased ability to implant.

Abstract
BACKGROUND Follicular aspirates represent a snapshot in time of conditions within the follicle at oocyte retrieval in women undergoing in vitro fertilization and embryo transfer. This clinical material has been much investigated and yet its cellular composition remains unclear. In this study we investigated the origin and profile of leukocytes found within follicular aspirates. METHODS We performed morphological and immunohistochemical analyses of follicular aspirates and peripheral blood obtained concurrently at oocyte retrieval. RESULTS There was no correlation between erythrocyte and leukocyte numbers in follicular aspirates. The profile of leukocyte subtypes within follicular aspirates was variable and differed significantly from the peripheral circulation in a significant proportion of the analysed samples. A subset of follicular aspirates displayed a marked increase in monocytes/macrophages and an apparent concomitant reduction in polymorphonuclear leukocytes compared with peripheral blood. CONCLUSIONS Leukocytes within follicular aspirates cannot be accounted for solely as a result of blood vessel damage during oocyte retrieval. The variation in leukocyte subtypes observed in some follicular aspirates may reflect a coordinated infiltration of these cells, characteristic of progressive inflammatory responses in other systems. The possibility that leukocyte variation is indicative of follicular maturation deserves further investigation due to its potential relevance in optimizing oocyte selection.

Abstract
PROBLEM To analyse percentage of total and memory CD27(+) B-cells and other lymphocyte subpopulations in the peripheral blood (PB) and follicular fluid (FF) of infertile married couples. METHOD OF STUDY Forty-eight couples from in vitro fertilization/embryo transfer (IVF/ET) programme were divided into four groups: patients with previous unsuccessful fertilization (n = 13), ectopic pregnancy (n = 8), multiple (at least three) failed IVF/ET (n = 18) and missed abortions (n = 9). Control group consisted of 15 married couples with healthy children. RESULTS PB memory CD27(+) B-cells were significantly decreased in all groups of infertile patients compared with controls. First group had increased memory B-cells percentages compared with the second group. The differences in the percentages of PB memory B-cells in third and fourth group compared with the first group were not statistically significant. FF memory B-cells in the first and third group were significantly increased compared with second and fourth group. The percentage of total FF B-cells in all groups were significantly decreased compared with their percentage in PB. Male partners of women from the first group had had significantly increased percentages of memory B-cells compared with the partners of women from the second group. Percentage of total T- and B-cells, CD4+ and CD8+ T-cells, NK cells and activated HLA-DR(+) T-cells in all groups were not significantly different from controls. We found no statistically significant difference between immunoglobulin E levels in all groups of patients. We found lower levels of IgA and IgM in FF compared with serum in all groups. CONCLUSION Infertile patients have significantly decreased percentage of CD27(+) B-cells in the PB. Abnormalities in the memory B-cell compartment may contribute to the pathogenesis of infertility. In the T-cell compartment abnormalities were not detected. It appears that hormonal stimulation did not influence cellular immunity parameters.

Abstract
A wealth of publications proposes that endometriosis and inflammation may have an unfavorable influence on fertility. A recent meta-analysis of assisted reproductive technologies demonstrated that, once confounding factors are controlled for, the pregnancy rate in women with endometriosis is approximately 50% of the rate of women with tubal factor infertility. Peritoneal fluid of women with endometriosis contains elevated amounts of macrophages and their secreted products, such as growth factors, cytokines, and angiogenic factors. Because reproductive organs are bathed in and thus will be influenced by peritoneal fluid, these proinflammatory mediators would affect various aspects of reproduction in women with endometriosis. Advanced stages of endometriosis may have easily understandable factors, such as distortion of the anatomy, causing infertility. On the other hand, in minimal or mild endometriosis mechanisms underlying reproductive failure are subtle and remain controversial. Recent reports suggest that inflammatory factors play a role in this endometriosis-associated reproductive failure. This review provides an overview of recent data on the effects of endometriosis-associated inflammation on fertility.

Abstract
One-fifth of all in-vitro fertilization (IVF) patients suffer from idiopathic infertility. A low fertilization rate is one of the most characteristic features of IVF in this group, probably caused by oocyte dysfunction. We speculate that an altered lymphocyte profile in follicular fluid (FF) may affect oocyte function and thus play a role in idiopathic infertility. Therefore, we compared levels of lymphocyte populations present in FF of 11 patients with idiopathic infertility (study group) with 29 patients in the control group, i.e. severe male factor infertility (n=17) or tubal factor infertility (n=12). Triple color flow cytometry was used to discriminate between T cells and NK cell subpopulations. In the idiopathic infertility group, a shift from T to NK cells was observed in FF as compared to the control group, caused mainly by a significant higher level of NK cells--20.3 and 13.6% (P<0.05), respectively. This high level of NK cells was due to a rise of the CD16+CD56dim NK cell subset. In peripheral blood, the NK cell levels showed a similar although not significant trend (P=0.08). As the CD16+CD56dim NK cell subpopulation is known for its cytotoxic properties, this subpopulation may negatively affect folliculogenesis and oocyte maturation, reflected by a diminished fertilization rate in the idiopathic infertility group. An altered lymphocyte profile in FF could therefore influence fertility in these patients.

Abstract
The present study explored the possible relationships between immune cell subsets and interleukin (IL)-12 or IL-13 levels in the peritoneal fluid of patients with and without endometriosis. Peritoneal fluid samples were obtained from 80 women while they were undergoing laparoscopy for pain, infertility, tubal ligation or re-anastomosis. The American Fertility Society scoring system was used to determine the extension of endometriosis. The peritoneal fluid mononuclear cells were analyzed for immunophenotyping using cytometry, whereas peritoneal fluid concentrations of interleukins were measured using two ultrasensitive commercially available enzyme-linked imnunosorbent assay kits. Significantly higher peritoneal fluid IL-12 levels were found in women with moderate or severe endometriosis (stages III and IV) than in healthy controls (p < 0.01). Conversely, subjects with endometriosis showed remarkably lower peritoneal fluid IL-13 concentrations than controls, independent of the severity of the disease (p < 0.05). Considering immune system effectors, patients with endometriosis presented a significantly higher peritoneal fluid CD8+/CD4+ ratio when compared with healthy controls. Moreover, the number of peritoneal fluid CD8+ and CD4+ activated T cells was significantly lower in the former than in the latter group, independent of the endometriosis stage. Connections were observed between peritoneal fluid interleukins and peritoneal fluid T cells: both patients with endometriosis and controls presented an inverse correlation between peritoneal fluid activated T cells and IL-13 levels, and a direct correlation between peritoneal fluid T cells and IL-12 concentrations. These data seem to suggest that a reciprocal modulation exists between peritoneal fluid cytokines and T lymphocyte subsets in patients with endometriosis.

Abstract
OBJECTIVE To investigate a possible correlation between interleukin-12 (IL-12) and IL-13 levels and lymphocyte subsets in the preovulatory follicles of patients with and without polycystic ovarian syndrome (PCOS). DESIGN Controlled clinical study. SETTING University hospital. PATIENT(S) Seventy-eight infertile women undergoing IVF-embryo transfer. INTERVENTION(S) The subjects underwent blood sampling, ovum retrieval, and embryo transfer. MAIN OUTCOME MEASURES Follicular fluid levels of T, androstenedione (A); IL-12, IL-13, activated T cells, T helper, and T-suppressor lymphocytes. RESULT(S) The level of IL-12 detected in follicular fluid (FF) was significantly lower in patients with PCOS than in normally ovulating women (mean: 1.47 +/- 0.3 pg/mL vs. 2.25 +/- 0.7 pg/mL, respectively); in contrast, FF IL-13 concentrations were significantly higher in the patients with PCOS than in the normally ovulating women (mean: 32.5 +/- 3.7 pg/mL vs. 19.6 +/- 2.5 pg/mL, respectively), as was the total number of activated T lymphocytes (11.5% +/- 1.5% vs. 4.8% +/- 0.4%). A significant correlation was observed between FF activated T-cell concentrations and FF IL-12, IL-13, T, and A levels. No significant differences were observed when these data were compared with embryological parameters. CONCLUSION(S) The present study shows significant differences in the correlation between FF IL-12 and IL-13 levels and T lymphocyte numbers in the subset of patients with PCOS as compared to normally ovulating women.

Abstract
Prospective and retrospective clinical trials suggest a decreased oocyte and embryo quality in women with endometriosis. Based on these observations, the authors described an altered intrafollicular milieu in endometriosis, which explains the bad quality oocytes and the resulting embryos with lower capacity to implant. Whether these changes affect the oocytes or are the consequence of genomic alterations manifested by biochemical and chromosomal differences in healthy women is an unresolved issue. If the effects of endometriosis on follicular development are nongenomic in origin, modulation of the process of folliculogenesis may be sufficient to treat the disease and cure infertility associated with endometriosis. A genomic defect needs specific genetic therapy, which currently is not available.

Abstract
The association between endometriosis and infertility is complex. Nevertheless, in the absence of tubal distortion considerable evidence suggests four principle factors likely to contribute to subfertility. These include impaired folliculogenesis, decreased fertilization, inflammatory factors in follicular, peritoneal and reproductive tract fluid, and implantation defects. The potential impact of each of these is critically examined. The role of endometriomas, prior surgeries and donor oocytes is also discussed.

Abstract
OBJECTIVE The aims of the present study were to (i) determine the presence and concentration of albumin fractions (alpha1, alpha2, beta, gamma), immunoglobulins (IgA, IgG, IgM) and cytokines [interleukin (IL)-6, IL-8, granulocyte-macrophage colony-stimulating factor (GM-CSF)] in periovulatory ovarian follicular fluid (FF) of in vitro fertilization (IVF) patients, (ii) examine the relationship between these parameters and the etiology of infertility as well as the IVF outcome and (iii) find out if these parameters in FF could be used as a predictive factor of IVF outcome. DESIGN The levels of albumin fractions, immunoglobulin and cytokines were measured from women who underwent IVF therapy for various indications and the results were compared between the patient groups and IVF outcome. MATERIALS AND METHODS Follicular fluid was obtained from 160 IVF patients. A total of 79 patients underwent controlled ovarian hyperstimulations (COH) either with follicle-stimulating hormone (FSH) or HMG. Whereas, the HMG was used for the second set of patients (n=81) - after down regulation with gondotropin-releasing hormone agonists (Gn-RHa) - the protein fractions were determined using electrophoresis separation. Immunoglobulins were measured using a commercial kits and the concentration of cytokines was determined by the highly sensitive enzyme-linked immunosorbent assay (ELISA) methods. RESULTS The stimulation regimens used have no effect on albumin (alpha1, alpha2, beta, gamma) and immunoglobulin (IgA, IgG, IgM) concentrations, as no significant difference was observed between the two groups. Besides, no specific relationship was found between the concentration of these investigated parameter in FF and etiology of infertility or fertilization, cleavage and pregnancy rate. Besides, there were no significant differences between the groups for any cytokine investigated. Moreover, there were no correlations between the concentration of IL-6, IL-8 and GM-CSF in FF and steroid hormone concentration in the blood at the day of oocytes retrieval or IVF outcome. IN CONCLUSION Total protein, albumin fraction, immunoglobulins and cytokines level in FF of patients undergoing COH for IVF therapy for various etiology of infertility could not be a useful parameter for predicting IVF outcome.

Abstract
PURPOSE To investigate the secretion of progesterone (P4) and corticosteroid binding globulin (CBG) by granulosa luteal cells (GC) as well as the mRNA levels of CBG and 3beta hydroxisteroid dehydrogenase (3beta HSD), in women with and without endometriosis in vivo and in vitro. METHODS Prospective study in a private, university-affiliated assisted reproduction unit, including women with severe endometriosis (n = 14) or without the disease (n = 20) undergoing in vitro fertilization/intracytoplasmic sperm injection and embryo transfer. GC were obtained from each follicle aspirated, pooled for each patient, and follicular and blood contaminating leukocytes depleted through immunomagnetic purification. Secreted P4 and CBG, and mRNA for both 3beta HSD and CBG were determined in vivo and in vitro using RIA and reverse transcription followed by competitive polymerase chain reaction (cRT-PCR). RESULTS The pattern of expression of 3beta HSD and CBG mRNAs in vivo and in vitro was similar in both groups. Also, GC from patients with endometriosis produced equal amounts of P4 and CBG than controls without the disease, either in freshly isolated cells or in 24-h cultures. CONCLUSIONS The GC function in terms of 3beta HSD and CBG mRNA expression and P4/CBG secretion does not seem to be altered in patients with endometriosis in comparison with those without this condition.

Abstract
OBJECTIVE To determine the concentrations of hyaluronan, E(2), and progesterone in follicular fluids (FFs) and the incidence of apoptotic granulosa cells. Also, to examine the relationship between the concentration of hyaluronan and follicular steroids, the incidence of apoptotic cells, and the fertilizability of the oocyte in the same follicle. DESIGN Samples of 130 follicles were retrospectively analyzed for hyaluronan and steroids and the incidence of apoptotic cells. SETTING The reproductive center in Yamagata University Hospital. PATIENT(S) Forty women infertile because of tubal damage or unknown causes undergoing IVF treatment were selected. INTERVENTION(S) The samples were collected from follicle aspirations. MAIN OUTCOME MEASUREMENT(S) The concentrations of hyaluronan and steroids in FFs, the incidence of apoptotic granulosa cells, and oocyte fertilizability. RESULT(S) The levels of hyaluronan in FF were found to correlate positively with P (r=0.444, P<0.0001) and the incidence of apoptotic cumulus granulosa cells (r=0.387, P=0.002) and inversely with E(2) (r = -0.601, P<0.0001) and free T (r = -0.344, P=0.001). The concentration of hyaluronan in FFs containing a subsequently fertilized oocyte after insemination was significantly lower than that in FFs containing a subsequently unfertilized oocyte (P=0.0005) (fertilized, 50.0 +/- 2.6 ng/mL; triploidy, 59.1 +/- 6.8; and unfertilized, 66.9 +/- 5.9). CONCLUSION(S) The concentration of hyaluronan in FF is an indicator for estimation of oocyte viability for fertilization.

Abstract
OBJECTIVE To further elucidate cortisol metabolism in the follicular microenvironment at the time of oocyte retrieval, the presence of 11beta-hydroxysteroid dehydrogenase (HSD) messenger (m)RNA transcripts in oocytes; cumulus cells; granulosa cells; and CD45(+), CD15(+) leukocytes was assessed semiquantitatively. DESIGN Controlled study using semiquantitative assessment of 11beta-HSD mRNA. SETTING University IVF center. PATIENT(S) Twenty-six patients undergoing controlled ovarian hyperstimulation for assisted conception. INTERVENTION(S) Metaphase II oocytes; cumulus cells; granulosa cells, and CD45(+), CD15(+) leukocytes from individual follicular fluid aspirates. MAIN OUTCOME MEASURES Semiquantitative analysis of PCR products after total RNA extraction and complementary DNA synthesis. RESULT(S) Periovulatory human oocytes; cumulus cells; CD45(+), CD15(+) leukocytes; and granulosa cells consistently express type 1 but not type 2 11beta-HSD mRNA. Expression of mRNA is greatest in cumulus cells. Type 1 11beta-HSD mRNA expression varies considerably in all cell types and among individual follicles and patients. CONCLUSION(S) These studies of mRNA expression suggest that the enzymes present both in and around the periovulatory oocyte will favor a high-cortisol environment.
