Abstract
Polycystic ovary syndrome (PCOS) is a heterogeneous entity comprising broad spectra of ovarian disorders with trademark features of metabolic syndrome like insulin resistance, obesity, and dyslipidaemia to name a few. Hyperhomocysteinemia, an independent risk factor of metabolic syndrome, has been suggested as a causative factor in spontaneous miscarriage in PCOS. However, it is yet to be resolved whether hyperhomocysteinemia has a contributory role in the pathogenesis or could direct long-term sequences of the syndrome. A total of 2355 women with history of one or more first trimester abortions were screened and 1539 were selected for the study. Selected patients were initially divided by the presence or absence of PCOS, while subsequent stratification was based on hyperhomocysteinemia, insulin resistance, and/or obesity. The miscarriage population/s was mostly represented by hyperhomocysteinemia in both the cohorts (PCOS: 69.08% vs. non-PCOS: 56.68%). ROC-AUC values suggest increased predisposition of hyperhomocysteinemia-mediated miscarriage (hyperhomocysteinemia: 0.778; insulin resistance: 0.601; BMI: 0.548). A probabilistic causal model was designed using dynamic Bayesian network to evaluate the time-series data points before, during, and after pregnancy which revealed a possibility of 32.24% (n = 79) of PCOS cohort developing hypertension, 26.94% (n = 66) of onset of diabetes and 4.49% cardiovascular disease 3 years following pregnancy. We conclude hyperhomocysteinemia may possibly contribute to spontaneous miscarriage and related to metabolic derailments later in life.

Abstract
Abstract
10-15% of clinically recognized pregnancies end in miscarriage. Hyperhomocysteinemia in pregnant women has been associated with deep venous thrombosis, recurrent miscarriage, preeclampsia to name a few. Impaired placental function due to overt oxidative stress is one of the key mechanisms in development of pregnancy loss. Paucity of pathway–based microarray approach in embryonic–endometrial communication warrants elucidation of distinct profile of miRNAs in hyperhomocysteinemia-associated pregnancy loss (HAPL). Hyperhomocysteinemia was induced at a dose of 100mg/kg body-weight/day for D1-D18 of pregnancy. Placental histology by haematoxylin-eosin staining documented thrombus with reduced area of spongiotropoblasts in chorionic plate vessel. Placental mRNA was subjected to microarray analysis followed by pathway-analysis using Ingenuity Pathway Analysis (IPA). Genes involved in reproductive physiology, inflammatory pathways, immune responses, homocysteine metabolism, glucose metabolism, and oxidative stress were differentially expressed in HAPL. 21 pathways documented by IPA, were skewed to 10 by recursive feature elimination highlighting possible deregulation/s. Expression/s was re-confirmed by quantitative real- time PCR (qRT-PCR), western blot and flow cytometric analysis (FACS). Nine priori molecules (PKM2, AKT, PI3K, NF-κB, COX-2, sflt-1, HIF-1α, bax, caspase 9) were specifically modulated in HAPL as demonstrated by protein and mRNA expression. A parallel increase in insulin signaling (PI3K+,AKT+), inflammation (COX2+,NF-κB+), hypoxia (sflt-1+,HIF-1α+), apoptosis (bax+,caspase9+) with concomitant decrease in pyruvate kinase M2 in hyperhomocysteinemic placental cells by FACS with CD56, a marker for pregnancy loss was documented. The findings provide evidence that an oxidative stress-mediated placental damage perhaps represents the pathogenesis of HAPL, which may explore pathway-based therapeutic options for recurrent miscarriage.10–15% of clinically recognized pregnancies end in miscarriage.

Abstract
Abstract
Study question
Can the whole organ-cervix be decellularized while maintaining its fiber ultrastructure and extracellular matrix (ECM) functionality?
Summary answer
Cervix after decellularization could maintain the physical properties, ECM was found to be intact and functional.
What is known already
ECM-rich bioscaffolds are obtained from the process that utilizes the decellularization of tissues and organs. Cervical bioengineering is needed for clinical cervicovaginal reconstruction and tissue constructs can help women with cervical abnormalities.
Study design, size, duration
Human cervices were obtained from hysterectomized samples from 3 women undergoing surgery for complete hysterectomy during January 2021 to December 2021
Participants/materials, setting, methods
Human cervices were obtained from hysterectomized samples from 3 women undergoing surgery and were subjected to whole organ decellularization. Various physical, chemical methods were employed to remove cellular remnants for a period of 10 days via perfusion of ionic and detergent solutions. Validation of complete decellularization was done via hematoxylin and eosin (H&E) staining, DNA quantification. ECM functionality was observed.
Main results and the role of chance
Well-organized ECM was obtained. Effective complete decellularization was dictated and verified by cervical tissue density, histopathological studies, DNA quantification and biochemical tests. H&E staining reflected the absence of any nuclear material in the endocervical and ectocervical tissues. Tissue microarchitecture and descending uterine artery were intact and could be helpful in the nutrient and gas exchange. DNA was found to be around 70 ng/mg tissue weight. Cell-free tissue-derived scaffolds were obtained along with a combination of growth factors and proteins.
Limitations, reasons for caution
Acellular cervical scaffold as a whole organ with vasculature intact for site-specific transplantation is a bigger question and still unaddressed.
Wider implications of the findings
Our study creates numerous prospects for in-vitro and in-vivo whole cervix tissue engineering. Site-specific tissue holds a promising avenue for the reconstruction of cervical abnormalities.

Abstract
Abstract
Study question
Do NOD-like receptor pyrin-containing 3 (NLRP3) signaling affect neutrophil extracellular traps (NET)-osis in women with stage III/IV endometriosis?
Summary answer
Inflammasome activation whether due to pathogen (disease itself) or damage-associated molecular pattern (through NET) might be one mechanism involved in establishing perturbed endometrium in endometriosis.
What is known already
Endometriosis is characterized by number of processes like vascularization, hypernociception, and fibrosis, cardinal cause being inflammation. Recently, expression of inflammasome components, including NLRP3 and apoptosis signal-regulating kinase has been demonstrated in human endometrium cueing involvement in uterine innate immunity. Moreover, a novel extracellular killing mechanism, NET, is documented to reflect an inflammatory status in deep infiltrating endometriosis. Since, endometriosis demonstrates similarities with chronic inflammatory and autoimmune disorders; we postulated inflammatory responses in endometriosis may become modulated through a feed-forward loop of NET-induced specific cytokine production thus providing insights against potentiality of endometriotic cells to limit progression of the disease.
Study design, size, duration
Twenty-two consented women (24-39 years) with endometriosis (Group A) (Stages III–IV) (based on ASRM-2018 guidelines) and age-matched counterpart/s of male sub-fertility (Group B; control), free of uterine abnormalities (n = 18) were recruited between January to December 2021 from Institute of Reproductive Medicine, Kolkata. Eutopic endometrium, were collected from women undergoing diagnostic laparoscopy (Group A) or by curettage from women undergoing endometrial ablation (Group B). Serum was collected during window-of-implantation (LH + 7) for both the group/s.
Participants/materials, setting, methods
Pro-(IFN-g, TNF-a, IL-6, TGF-b) and anti-inflammatory (IL-10, IL-13, IL-4, IL-5) cytokines was evaluated by western blot. Expression level of inflammasome-related proteins (NLRP3, ASC, CASPASE1, PYCARD, IL-1-b) and mRNA expression was estimated by western-blot and quantitative-real-time PCR (qRT-PCR) respectively from tissue biopsies in Group A and B. SYTOX® green assay by flow-cytometry and neutrophil-elastase activity by immunofluorescence was done to quantify and characterize NET production in blood monocytes. P < 0.05 was considered statistically significant.
Main results and the role of chance
The mean (±SD) age of study population was 31.6±5.2 years. Hyperestrogenic milieu possibly stimulated (p < 0.001) pro-inflammatory molecules (IFN-g, TNF-a, IL-6, TGF-b) in endometriosis as observed by western-blot and qRT-PCR. A significant up-regulation (p < 0.001) was observed in relative mRNA expression of NLRP3 and PYCARD gene in Group A. However, caspase 1 expression documented non-significant variation in biopsies from endometriosis patients. Western blot corroborated the finding/s. The outcome of NLRP3 activation was supported by increased (p < 0.002) mRNA expression of IL-1b. NETs were detected significantly higher (p < 0.01) in 54.54% (12/22) patients in group A compared to control (16.66%; (3/18)). Moreover, quantification of NETs showed a significantly higher amount in endometriosis compared to group B (0.097 vs. 0.02, p < 0.03).
Spermann-rank correlation by SPSS version22 revealed positive correlation between IL-1b with NLRP3 (r = 0.56, p< 0.001), PYCARD (r = 0.11, p< 0.01); and caspase1 (r = 0.16, p< 0.01) and IL-1b (r = 0.47, p< 0.01) with NET-positive cell/s in endometriosis. Moreover, posterior cul-de-sac lesions correlated positively with NET-positive cell/s (r = 0.29; p < 0.01) cueing to possible prognostic marker/s. In summary, a coordinated-fashioned action of components of NLRP3 inflammasome machinery may regulate production of NET/s forming a complex network allowing communication between cell-types in order to maintain viability and development of endometrial lesion/s.
Limitations, reasons for caution
Our findings need to be replicated in larger study cohort/s, especially stratified by severity of endometriosis sub-groups and in women of different ethnicities. Another limitation is the missing information about NETs in normal functioning human endometrium throughout the menstrual cycle.
Wider implications of the findings
The proposed study aims to understand potential role of NLRP3 inflammasome complex as a “double-edged sword” in the development and pathophysiology of endometriosis. Therapeutic alternatives that aim to re-balance the pro- to anti-inflammatory milieu in the endometrium should consider the inflammasome as part of the equation.

Abstract
Abstract
Study question
Do genetic components and functional annotation/s in eutopic endometrium share significant difference to influence diagnosis in adenomyosis?
Summary answer
An integrated clinico-transcriptomic approach chalk the chief individual as well as hub genes in women with adenomyosis to set the algorithm for improved diagnosis.
What is known already
Adenomyosis often document similar presentation/s to other gynecological diseases including endometriosis making the diagnosis difficult. Differentially expressed transcripts and proteins were identified by transcriptomic analysis and genome-wide profiling of eutopic and ectopic endometrial samples in women with endometriosis. Biological networking and functional enrichment analysis enable prioritization of candidate genes for validation purpose in target tissue. Recently, key pathways in proliferative stage of adenomyosis at transcriptome level were documented in eutopic endometrium. However, characterization of functional annotations may assist clinicians to evaluate if they share systematic correlations predictive of ultrasonographic finding/s for help in everyday practice in diagnosing adenomyosis .
Study design, size, duration
Microarray datasets (GSE7307 and GSE78851) were selected from Gene Expression Omnibus database (GEO), which contains endometriosis, adenomyosis and normal endometrial tissues. An in-depth bioinformatic analysis was done to determine differentially expressed genes (DEGs) on GEO2R platform; followed by gene ontology (GO), KEGG pathway enrichment and protein-protein interaction (PPI) analysis by DAVID (http://david.ncifcrf.gov) and Cytoscape (version 3.8.2) respectively. PPI network was predicted further using a search tool, STRING (http://string-db.org; version 11.0) for retrieval of interacting genes.
Participants/materials, setting, methods
Eutopic endometrial samples were obtained during window of implantation from women (n = 10) with endometriosis, adenomyosis and adenomyosis-associated-endometriosis as diagnosed by laparoscopy, and, trans-vaginal ultrasound (TVUS) between March to December 2021 from Institute of Reproductive Medicine, Kolkata. Counterpart/s of male sub-fertility, defined by World-Health-Organization criteria (5th edition) was treated as control (n = 10). In-silico findings were validated by quantitative-real-time PCR (qRT-PCR). TVUS findings and gene expression/s were correlated by Spermann-rank correlation test. P < 0.05 was considered statistically significant.
Main results and the role of chance
A total of 4474 and 1061, significant DEGs (log fold-change>1, p < 0.05) were identified from datasets of endometriosis and adenomyosis respectively. GO function/s included common biological processes and molecular function/s, namely, epithelial-to-mesenchymal transition (EMT), metallopeptidase activity and extracellular matrix remodelling. EMT and Wnt signaling ranked top position/s in KEGG pathway enrichment. Among sixty-four common DEGs, four genes, namely, SERPINA1, MMP11, THBS1, MMP7 have maximal node degree (>2) and MCODE (k = 2) in PPI network and were prioritized as hub genes. STRING analysis computed the network of common hub genes between adenomyosis and endometriosis. qRT-PCR findings confirmed down-regulation (p < 0.02) of SERPINA1, and MMP11 in adenomyosis compared to endometriosis and MMP7, and THBS1 in both endometriosis and adenomyosis (p < 0.03) compared to control. Down-regulation (p < 0.003) of SNORD116, MYH11 and PIGR was simultaneously observed in adenomyosis only as compared to endometriosis. Similar gene expression/s as to adenomyosis was documented in combined cohort because of possible presence of common pathology. Interestingly, posterior-wall thickness (PWT) on TVUS was positively correlated with MMP11 (r = 0.88; p<0.03) and SERPINA1 (r = 0.94; p<0.01) in adenomyosis. MMP-11 also exhibited positive correlation with PWT (r = 0.85; p<0.03) and uterine-size (r = 0.88; p<0.03) in endometriosis and combined cohort respectively while MYH11 negatively correlated (r=-0.97; p<0.02) with uterine-size in adenomyosis associated endometriosis.
Limitations, reasons for caution
The heterogeneous nature of data for bioinformatic analysis is a major limitation. Moreover, only mild adenomyosis was considered in the study; hence, results could differ in women with co-occurrence of other gynecological condition/s and/or in severe cases of adenomyosis. The observed differences need to be replicated in larger study cohort/s.
Wider implications of the findings
We identify a set of novel hub genes and enrichment pathways in receptive phase which provide an in-depth discriminative understanding between pathogenesis of endometriosis and adenomyosis. Our results suggest a dys-regulated micro-environment run an algorithmic cascade for perturbed uterine preparation (in adenomyosis), thus providing platform for newer therapeutic targets.

Abstract
Abstract
Study question
Is serum homocysteine combined with uterine-artery Doppler were effective in predicting preeclampsia (≥140mmHg/≥90mmHg blood pressure) in singleton pregnancy during 11–15 weeks of gestation?
Summary answer
Combination of serum homocysteine levels with uterine-artery Doppler is superior to individual presence of biochemical/ultrasound marker/s making the duo effective for early screening in preeclampsia.
What is known already
American College of Obstetricians and Gynecologists and National Institute for Care and Health Excellence recommend identifying patients who are at high risk of developing preeclampsia based on medical history. Recently, biochemical and ultrasound markers were investigated for prediction of preeclampsia, but none of them were predictably reliable, valid, and suitable for routine clinical use. Increased levels of homocysteine in 1st-trimester, seems to signal onset of preeclampsia later in pregnancy portraying severity of the disease as well. We aimed to identify predictive value of serum homocysteine combined with uterine-artery Doppler in singleton pregnancy during 11–15 weeks of gestation for preeclampsia.
Study design, size, duration
One hundred forty-two consented singleton pregnant women (28-45 years) at gestational age of 11–15 weeks, recruited between January to December 2021 from Institute of Reproductive Medicine, Kolkata were enrolled in the study. Women who used aspirin as a prophylaxis for preeclampsia or were diagnosed to have fetal, structural or chromosomal abnormalities were excluded from the study (n = 7). Maternal age, weight and height, mean arterial pressure, parity, and obstetric history were documented.
Participants/materials, setting, methods
Uterine-artery Doppler ultrasound and serum homocysteine levels were performed transabdominally and using ELISA respectively. Pregnancy outcomes were recorded. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) at optimal cut-off values were determined to predict preeclampsia. Optimal cut-off values for homocysteine levels were calculated using receiver operator characteristic curve (ROC). Chi-square test, Fisher’s exact test, unpaired t test, and Mann–Whitney U test were used when appropriate. P-value <0.05 was considered statistically significant.
Main results and the role of chance
16 cases had preeclampsia (11.26%) of whom 9 had early-onset preeclampsia (6.33%). Baseline characteristics including maternal-age (>35 or<), parity, body-mass- index, and gestational-age at measurement were not significantly different between two groups excepting higher (p < 0.001) mean arterial blood pressure (mmHg) at first trimester (97.2±6.4 vs. 81.1±7.2) in preeclampsia. Preeclamptic women had significantly higher (p < 0.001) serum homocysteine levels (μmol/l) (26.1±3.5 vs 10.2± 5.6) than normotensive pregnant women (n = 119). No difference in mean pulsatility (PI) of uterine-artery was observed (1.78±0.64 vs. 1.72±0.48) excluding significantly high (p > 0.02) in women with early-onset preeclampsia than control (2.11±0.81 vs. 1.39±0.92). However, lower (p < 0.01) gestational age (weeks) (35.4±2.1 vs. 37.6±1.4), and neonatal birth weight (gms) (2937.3±578.2 vs. 3227.6±421.5) with higher (p < 0.001) preterm delivery (25% vs 5.04%), low birth weight (25% vs 5.04%) and neonatal respiratory distress syndrome (12.5% vs. 0.84%) was documented in preeclampsia than control/s. The optimal cut-off value of serum homocysteine with PI levels, from ROC (AUC=0.735, p < 0.001) was superior to individual ROC (AUC=0.451; AUC=0.268). The sensitivity, specificity, PPV, and NPV were 67.7%, 70.5%, 1.7%, and 98.5%, respectively using a combination of abnormal serum homocysteine levels with abnormal uterine artery Doppler PI (above 95th percentile) and used as a predictive value for preeclampsia.
Limitations, reasons for caution
The limitation of this study was that there were small cases of early-onset preeclampsia. Additional studies with a larger sample size of early-onset preeclampsia and other models using serum homocysteine, combined with uterine artery Doppler, and maternal characteristic risk factors should be conducted.
Wider implications of the findings
Early screening of preeclampsia by using combination of serum homocysteine and uterine artery Doppler during first trimester (11–15 weeks) at the same visit may be more effective and allows the timing for using early low-dose aspirin prophylaxis in order to prevent preeclampsia.

Abstract
Abstract
Study question
Can metabolic picture of cumulus cell (CC) assess assisted reproductive technology outcome/s in women with adenomyosis/endometriosis and have implications on treatment decisions?
Summary answer
The differentially expressed genes between uterine pathologies explain the functional gap to identify diagnostic/prognostic markers of CC and further dissect molecular contribution to oocyte maturation.
What is known already
A healthy intra-follicular environment supports achievement of oocyte developmental competence (ODC) largely via coordinated CC-follicular fluid (FF) crosstalk. Lately, promising studies document CC of endometriosis are involved in important pathways for ODC like oxidative phosphorylation, metabolism, mitochondrial function and acetylation to name a few. Similar presentation/s of adenomyosis to other gynecological diseases including endometriosis makes the diagnosis difficult. Given that the functional integrities of CCs are susceptible to concurrent pathological conditions, understanding the influence of CCs on oocyte quality compared to routine morphological analysis in presence of deleterious systemic or pelvic conditions may impact clinical decisions.
Study design, size, duration
Twenty-eight consented patients undergoing IVF-ICSI between January to December 2021at Institute of Reproductive Medicine, Kolkata were enrolled. CCs obtained and corresponding oocyte maturation was assessed. They were sub-stratified (n = 9) according to uterine pathologies: adenomyosis (Group A), and endometriosis (Group B) as diagnosed by transvaginal ultrasound (TVUS). Counterpart/s of male sub-fertility, defined by World Health Organization criteria (5th edition) was treated as control (Group C; n = 10). CC from mature MII and immature GV oocytes were compared.
Participants/materials, setting, methods
CCs collected following oocyte-denudation were evaluated by Trypan Blue viability test. Patient age and embryo development were recorded with respect to each cumulus complex. Real Time-quantitative polymerase-chain-reaction (qRTPCR) was performed for glycolysis (PFKP, PKM2, ALDOA, LDHA, TPI1), cholesterol-biosynthesis (CYP51, MVK, PMVK, EBP) and extracellular-matrix (PTGS2, PTX3, TNFAIP6, VCAN) related gene/s known to have important functions in cumulus expansion and metabolism. Patient characteristics and gene expression were correlated by Spearman’s correlation. P < 0.05 was considered statistically significant.
Main results and the role of chance
A significant higher (p < 0.001) age (A vs B: 35.77±2.33 vs 25.88± 1.76; A vs C: 35.77±2.33 vs 31.9±1.98) and increased number of oocytes retrieved (A vs B: 11.22±1.56 vs 8.55±0.88) was documented in adenomyosis cohort. Immature oocytes from Group A expressed enhanced cholesterol/steroid biosynthesis, with significant (A vs B; p < 0.01) up-regulation of CYP51, MVK, PMVK, EBP in spite of hyper-estrogenic environment in peripheral blood. On contrary, significant attenuation (p < 0.01) of cholesterol biosynthesis was documented in endometriosis cohort compared to control. Expression of PTGS2, PTX3 and VCAN was down-regulated (p < 0.001) (which together mediate cumulus expansion and oocyte maturation, as well as corpus luteum formation and maintenance and reduce spindle abnormalities) in both Group A and B. Expression/s of CC-PFKP and PKM2 was lower in immature compared to mature oocytes (B vs C; p < 0.01) in endometriosis making the duo responsible for follicular/oocyte growth, and embryonic development. This supports the role in promoting cumulus expansion and oocyte competence. Expression levels of other genes including ALDOA, LDHA, TPI1, and TNFAIP6 were not associated with oocyte maturity, and fertilization in either cohort/s. Interestingly, levels of VCAN, TNFAIP6, PTX3 changed significantly as a function of the subject’s age and embryo development.
Limitations, reasons for caution
Our findings are limited by the relatively small sample size and inherent biological variability of human samples. Several yet known or unknown factors are presumably involved in the implantation process of adenomyosis and/or endometriosis. Multi-centric systematic studies are needed to corroborate these findings and account for the probable confounding factors.
Wider implications of the findings
A differential metabolic dependence of CC play essential role in oocyte competence in adenomyosis influencing cumulus expansion and oocyte maturation. This would be useful to do further studies to know how molecular interface of implantation capacity with live-birth rate would be affected to complement embryonic morphological assessment/s.

Abstract
Etiology of male infertility is intriguing owing to complex genetic regulation of human spermatogenesis and ethnic variations in genetic architecture of human populations. The present study characterizes the role of Y chromosome specific spermatogenic regulator testis-specific protein Y-encoded 1 (TSPY1) gene mutation in spermatogenic failure. This case-control study includes 163 cases of spermatogenic failure and 175 age-matched fertile men as controls. We found five novel base substitutions, namely, MT162695, MN879413, MN889982, MN889983, MN719943, two deletions MN734578 and MN734579, three novel insertions MN719941, MN719942 and MN719944 through Sanger's dideoxy sequencing of TSPY1 gene reading frame. All these mutations exhibited strong association with male infertility. In silico analyses suggest prospective disruption in splice sites and alteration in different isoforms of TSPY1 transcripts and amino acid sequence in TSPY1 protein. The study provides novel evidence in favour of implication of TSPY1 gene in male fertility. The outcome sheds light to get insight into the issue of idiopathic male infertility in Bengali population.

Abstract
Background Etiology of male infertility is intriguing and Y chromosome microdeletion within azoospermia factor (AZF) sub‐regions is considered major cause. We conducted a screening for Y chromosome microdeletion in an infertile male cohort from West Bengal, India to characterize Y chromosome microdeletion among infertile men. Methods We recruited case subjects that were categorized on the basis of sperm count as azoospermia (N = 63), severe oligozoospermia (N = 38), and oligozoospermia (N = 17) and compared them with age, demography, and ethnicity matched healthy proven fertile control males (N = 84). Sequence Tagged Site makers and polymerase chain reaction based profiling of Y chromosome was done for AZF region and SRY for cases and controls. Results We scored 16.1% of cases (19 out of 118) that bear one or more microdeletions in the studied loci and none among the controls. The aberrations were more frequent among azoospermic males (17 of 19) than in severe oligozoospermic subjects (2 of 19). Conclusion Our study provides the results of screening of the largest Bengali infertile men sample genotyped with the maximum number of STS markers spanning the entire length of Y chromosome long arm. Y chromosome microdeletion is a significant genetic etiology of infertility among Bengali men.

Abstract
PURPOSE To identify the contribution of mutations in the Desert Hedgehog (DHH) gene to the disorders of sexual differentiation (DSD) and male infertility. METHODS The study included a total 430 subjects, including 47 gonadal dysgenesis cases, 6 patients with undescended testis and infertility characterized by azoospermia, 125 infertile male patients characterized by oligoasthenozoospermia, 24 patients with oligoasthenoteratozoospermia, and 200 ethnically matched normozoospermic fertile men who had fathered a child in the last two years. Sequencing of the complete coding region of the DHH gene was undertaken to find its contribution to the DSD and male infertility. RESULTS We observed four novel mutations in the DHH gene in the cases with different reproductive anomalies. A synonymous substitution, c. 543C>T (p.His181His) was observed in 6.6% oligoasthenozoospermic infertile males and 1.5% normozoospermic fertile control samples (RR = 4.4077, 95%CI 1.19-16.29). Another synonymous substitution, c.990G>A (p.Ala330Ala) was observed in an infertile patient with unilateral undescended testis (case #12). Insertion of G at c.1156insG (p.Arg385fs) was observed in a case with bilateral undescended testis and azoospermia (case #23). In gonadal dysgenesis category, two mutations, insertion of G at c.1156insG (p.Arg385fs) and c.997A>G (p.Thr333Ala) substitution were observed in one case (case #34). These mutations were completely absent in control samples. CONCLUSION Mutations in the DHH gene impact reproduction with mild mutations affecting fertility, and severe or multiple mutations resulting in gonadal dysgenesis.

Abstract
Deletions in the AZoospermia Factor (AZF) regions (spermatogenesis loci) on the human Y chromosome are reported as one of the most common causes of severe testiculopathy and spermatogenic defects leading to male infertility, yet not much data is available for Indian infertile men. Therefore, we screened for AZF region deletions in 973 infertile men consisting of 771 azoospermia, 105 oligozoospermia and 97 oligoteratozoospermia cases, along with 587 fertile normozoospermic men. The deletion screening was carried out using AZF-specific markers: STSs (Sequence Tagged Sites), SNVs (Single Nucleotide Variations), PCR-RFLP (Polymerase Chain Reaction - Restriction Fragment Length Polymorphism) analysis of STS amplicons, DNA sequencing and Southern hybridization techniques. Our study revealed deletion events in a total of 29.4% of infertile Indian men. Of these, non-allelic homologous recombination (NAHR) events accounted for 25.8%, which included 3.5% AZFb deletions, 2.3% AZFbc deletions, 6.9% complete AZFc deletions, and 13.1% partial AZFc deletions. We observed 3.2% AZFa deletions and a rare long AZFabc region deletion in 0.5% azoospermic men. This study illustrates how the ethnicity, endogamy and long-time geographical isolation of Indian populations might have played a major role in the high frequencies of deletion events.

Abstract
Necrotic enteritis (NE) is an economically important disease of broiler chickens that is caused primarily by Clostridium perfringens strains that produce the NetB toxin. It is controlled in North America principally through the application of in-feed antimicrobials, but alternative control methods, such as vaccination, are urgently needed. We previously identified a cluster of C. perfringens genes prevalent in disease-causing strains, denominated VR-10B, that is predicted to encode a pilus. The current study evaluated the ability of three predicted pilin structural subunits (CnaA, FimA, FimB) to protect against NE in two immunization studies. In the first study, young broiler chickens were immunized twice intramuscularly (i.m.) with CnaA or FimA, which resulted in only a weak serum antibody response, and no reduction in the severity of intestinal lesions following experimental challenge with C. perfringens strain CP1. In the second study, chickens were injected subcutaneously (s.c.) with CnaA, FimB, or a combination of all three proteins, on days 7, 14 and 19, which resulted in a marked antibody response specific to each antigen. Chickens immunized with either CnaA or FimB had significantly reduced NE lesion severity, whereas immunization with all three proteins in combination did not provide protection. Western blot experiments using serum from immunized birds were also performed, providing the first experimental evidence to suggest that this locus may in fact encode a functional pilus structure.

Abstract
RESEARCH QUESTION Reports on the effect of adenomyosis on assisted reproductive technology (ART) outcomes are conflicting. Does presence of adenomyosis affect reproductive outcome in IVF cycles in women pretreated with gonadotrophin releasing hormone (GnRH) agonist? DESIGN In this retrospective cohort study, 973 women were divided into four groups: only endometriosis (n = 355); endometriosis and adenomyosis (n = 88); adenomyosis alone (n = 64); and tubal factor infertility as controls (n = 466). The pregnancy outcome parameters (clinical pregnancy, miscarriage rate, live birth rate) were compared between these groups. RESULTS The clinical pregnancy rate was 36.62% in women with endometriosis alone, 22.72% in women with endometriosis and adenomyosis, 23.44% in women who only had adenomyosis and 34.55% in controls. Miscarriage rates were as follows: 14.62%, 35%, 40% and 13.04%, respectively. Live birth rates were 27.47% in controls; 26.48% in women with only endometriosis; 11.36% in women with endometriosis and adenomyosis; and 12.5% in women with only adenomyosis. Live birth was observed to be less in adenomyosis groups compared with controls and women with only endometriosis. No significant difference was observed in clinical pregnancy, miscarriage or live birth rate between controls and women with only endometriosis. Live birth rate was significantly different between controls and women with adenomyosis only (P = 0.01) and women with endometriosis and adenomyosis (P = 0.002). CONCLUSION Presence of adenomyosis seems to have adverse effects on IVF outcomes in clinical pregnancy rate, live birth rate and miscarriage rate. Screening for adenomyosis might be considered before ART so that the couple has better awareness of the prognosis.

Abstract
PURPOSE An alternative option to human chorionic gonadotropin (hCG) is GnRH agonist (GnRH-a) for ovulation trigger in intrauterine insemination (IUI) cycles. This study aims to compare the efficacy of GnRH-a with hCG in women with history of follicular-endometrial asynchrony after clomiphene in IUI cycles. METHODS This prospective observational study recruited 631 women with unexplained infertility and follicular-endometrial asynchrony (follicle ≥ 18 mm, endometrial thickness (ET) < 7 mm) in previous two failed clomiphene/IUI cycles. Overall 27 patients with synchronized follicular-endometrial relationship and 49 women with persistent ET < 7 mm and/or follicle > 26 mm were excluded. Remaining women (n = 555) were divided into two groups: Group A (n = 285) received GnRH-a and Group B (n = 270) received hCG ovulation trigger. Finally, 513 patients, who underwent IUI, were analysed. RESULTS Cancellation due to luteinized unruptured follicle was more in hCG group (P = 0.01). Higher clinical pregnancies (10.33 vs. 4.96%, P = 0.03) and live birth rates (8.86 vs. 4.13%, P = 0.03) were noted with GnRH-a trigger. Miscarriage rate was comparable in both the groups (10.71 and 16.67% in Group A and Group B, respectively). CONCLUSION In unexplained infertility, GnRH agonist is an useful alternative for triggering ovulation in women with follicular-endometrial asynchrony following clomiphene induction.

Abstract
Endometriosis is a common benign gynecological disease, characterized by growth and proliferation of endometrial glands and stroma outside the uterus. With studies showing metabolic changes in various biofluids of endometriosis women, we have set upon to investigate whether endometrial tissue show differences in their metabolic profiles. 1H NMR analysis was performed on eutopic endometrial tissue of women with endometriosis and controls. Analysis was performed on spectral data and on relative concentrations of metabolites obtained from spectra using multivariate and univariate data analysis. Analysis shows that various energy, ketogenic and glucogenic metabolites have significant altered concentrations in various stages of endometriosis. In addition, altered tissue metabolites in minimal and mild stages of endometriosis were explored in serum of these patients to assess their role in disease diagnosis. For Stage I diagnosis alanine was found to have 90% sensitivity (true positives) and 58% specificity (true negatives). For Stage II diagnosis alanine, leucine, lysine, proline and phenylalanine showed significant altered levels in serum. While sensitivity of these serum metabolites varied between 69.2–100% the specificity values ranged between 58.3–91.7%. Further, a regression model generated with this panel of serum markers showed an improved sensitivity and specificity of 100% and 83%, respectively for Stage II diagnosis.

Abstract
Severe ovarian hyperstimulation syndrome (OHSS) is a potentially life-threatening complication of assisted reproductive technology. Herein, we report the case of an infertile couple, with the husband being azoospermic, who underwent in-vitro fertilisation and intracytoplasmic sperm injection at our institute. The woman presented with late OHSS 7 days after embryo transfer. Inpatient management was performed with intensive surveillance. Oral cabergoline was started prophylactically but was replaced by the vaginal route due to intolerance. Transvaginal paracentesis was performed five times over 20 days, and a total of 27 L of ascitic fluid was drained. The patient improved substantially and had a further uneventful pregnancy course. This case report helped us theorise that large-volume paracentesis is safe and efficacious in the management of severe OHSS. In addition, the vaginal route of cabergoline administration is more favourable than the oral route in view of lesser side effects and better patient compliance.

Abstract
Polycystic ovary syndrome (PCOS) is one of the most commonly occurring metabolic and endocrinological disorders affecting women of reproductive age. Metabolomics is an emerging field that holds promise in understanding disease pathophysiology. Recently, a few metabolomics based studies have been attempted in PCOS patients; however, none of them have included patients from the Indian population. The main objective of this study was to investigate the serum metabolomic profile of Indian women with PCOS and compare them with controls. Proton nuclear magnetic resonance (1H NMR) was used to first identify the differentially expressed metabolites among women with PCOS from the Eastern region of India during the discovery phase and further validated in a separate cohort of PCOS and control subjects. Multivariate analysis of the binned spectra indicated 16 dysregulated bins in the sera of these women with PCOS. Out of these 16 bins, 13 identified bins corresponded to 12 metabolites including 8 amino acids and 4 energy metabolites. Amongst the amino acids, alanine, valine, leucine and threonine and amongst the energy metabolites, lactate and acetate were observed to be significantly up-regulated in women with PCOS when compared with controls. The remaining 4 amino acids, l-glutamine, proline, glutamate and histidine were down-regulated along with 2 energy metabolites: glucose and 3-hydroxybutyric acid. Our findings showed dysregulations in the expression of different metabolites in the serum of women with PCOS suggesting the involvement of multiple pathways including amino acid metabolism, carbohydrate/lipid metabolism, purine and pyrimidine metabolism and protein synthesis.

Abstract
Successful implantation is dependent on the appropriate decidualization of endometrial stromal cells for the establishment of pregnancy in women. Mycobacterial heat shock protein 65 (HSP65) is involved in pathogenesis of the genital tuberculosis (GTB), one of the common causes of infertility in emerging countries. Though implantation failure appears to be the major cause, understanding the status of decidualizaiton process in women diagnosed with GTB has not been thoroughly addressed. We, therefore, explored the effect of HSP65 protein on the endometrial cell metabolism during in vitro decidualization. In order to identify the cellular metabolism of decidual cells with and without HSP65 treatment, proton NMR based characterization of metabolites extracted from cells and culture media were performed. In presence of HSP65, significant reduction in the decidual phenotype of endometrial stromal cells and prolactin expression is suggestive of impairment in decidualization. The intracellular and extracellular metabolic changes in HSP65 treated endometrial stromal cells produced a distinct pattern, reflecting the interaction between the protein and cellular metabolism. HSP65 mediated dysregulation in cellular metabolism is associated with poor decidualization. Besides enriching the present knowledge on metabolic changes underlying stromal cells decidualization, these findings assist in identifying potential molecular causes for decidualization failure in GTB women.

Abstract
PURPOSE This study aims to describe the role of implementing good laboratory practices to improve in vitro fertilization (IVF) outcomes which are of great interest for practitioners dealing with infertility. METHODS Certain modifications were introduced in May 2015 in our IVF laboratory like high-efficiency particulate air CODA system, steel furniture instead of wooden, use of new disinfectants like oosafe, and restriction of personnel entry along with avoidance of cosmetics like perfume to improve pregnancy rates. Volatile organic compound (VOC) meter reading was monitored at two time points and five different places in the laboratory to compare the embryonic development parameters before (group A: July 2014-April 2015) and after (group B: July 2015-April 2016) remodeling. RESULTS The IVF outcomes from 1036 cycles were associated in this study. Reduction in VOC meter readings, enhanced air quality, improvement in blastocyst formation rate, implantation, and clinical pregnancy rate were observed in the laboratory after implementation of new facilities. Results illustrated that the attention must be focused on potential hazards which expose laboratories to elevated VOC levels. Blastocyst formation rate increased around 18%. Implantation rate, clinical pregnancy rate, and live birth rate increased by around 11, 10, and 8%, respectively. CONCLUSION In conclusion, with proper engineering and material selection, we have been able to reduce chemical contamination and adverse effects on culture with optimized IVF results. SUPPORT None.

Abstract
PURPOSE The study aimed to investigate key intrafollicular prognostic factors among various cytokines and angiogenic molecules for prediction of mature oocytes and good-quality embryos in women with endometriosis undergoing in vitro fertilization (IVF). METHODS Paired follicular fluid and serum samples were collected from 200 women with advanced stage endometriosis and 140 normal ovulating women during oocyte retrieval. The concentrations of cytokines (pro-inflammatory: IL-1β, TNF-α, IL-2, IL-8, IL-12, IFN-γ; anti-inflammatory: IL-4, IL-6, IL-10) and angiogenic molecules (vascular endothelial growth factor (VEGF), adrenomedullin, angiogenin) were determined in follicular fluid and serum using ELISA. Expression of these molecules was subjected to multivariate analysis for the identification of major predictive markers of oocyte and embryo quality. Receiver operating characteristic (ROC) curve was applied to determine the best cutoff point for the discrimination between mature and immature oocytes in these women. RESULTS Significant increases in levels of cytokines and angiogenic molecules were observed in women with endometriosis compared to controls (P < 0.001). From the validated partial least squares-discriminant analysis (PLS-DA) model, IL-8, IL-12, and adrenomedullin were identified as the most important factors contributing to endometriosis and were negatively associated with oocyte maturity and embryo quality. CONCLUSION The levels of IL-8, IL-12, and adrenomedullin may be good indicators of embryo and oocyte quality in endometriosis patients undergoing IVF. Further studies are necessary to ascertain the potential of these markers for oocyte and embryo developmental competence which may help improve the chances of a successful IVF in endometriosis patients.

Abstract
STUDY QUESTION Is there any difference at the serum metabolic level between women with recurrent implantation failure (RIF) and women with recurrent implantation success (RIS) when undergoing in vitro fertilization (IVF)? SUMMARY ANSWER Eight metabolites, including valine, adipic acid, l-lysine, creatine, ornithine, glycerol, d-glucose and urea, were found to be significantly up-regulated in women with RIF when compared with women with RIS. WHAT IS KNOWN ALREADY Despite transfer of three high-grade embryos per cycle, RIF following three or more consecutive IVF attempts occurs in a group of infertile women. Conversely, there is a group of women who undergo successful implantation each cycle, yet have a poor obstetric history. STUDY DESIGN, SIZE, DURATION This study was conducted over a period of 10 years (January 2004-October 2014). Groups of 28 women with RIF (age ≤40 years and BMI ≤28) and 24 women with RIS (age and BMI matched) were selected from couples with primary infertility reporting at the Institute of Reproductive Medicine, Kolkata, India. Women recruited in the RIF group had history of implantation failure in at least three consecutive IVF attempts, in which three embryos of high-grade quality were transferred in each cycle. PARTICIPANTS/MATERIALS, SETTING, METHODS Blood samples were collected from both the groups during the implantation window following overnight fasting for at least 10 h (7-10 days post ovulation). Samples were analyzed using a 700 MHz NMR spectrometer and acquired spectra were subjected to chemometric and statistical analysis. Serum levels of endothelial nitric oxide synthase (eNOS) were measured using an enzyme immunoassay technique. MAIN RESULTS AND THE ROLE OF CHANCE Valine, adipic acid, l-lysine, creatine, ornithine, glycerol, d-glucose and urea were found to be significantly down-regulated in women with RIS when compared with those with RIF, with fold change values of 0.81, 0.82, 0.79, 0.80, 0.78, 0.68, 0.76 and 0.74, respectively. Further, serum eNOS was found to be significantly lower in women with RIF when compared with RIS (P < 0.05), indicating possible impairment in nitric oxide production. Metabolites, mostly related to energy metabolism, lipid metabolism and the arginine metabolic pathway were found to be considerably altered and are likely to be associated with the RIF phenomenon. However, the interplay between these molecules in RIF is complex and holds merit for further exploration. LIMITATIONS, REASONS FOR CAUTION In-depth studies of the arginine metabolic pathway in endometrial tissues seem necessary to validate our findings. A limitation of the present study is that the metabolic level changes, eNOS and nitric oxide levels have not been investigated in the endometrial tissues of the two groups of women. It would be interesting to investigate whether there exists a direct link between metabolic dysregulation and genetic factors that affects implantation in RIF women. WIDER IMPLICATIONS OF THE FINDINGS We speculate that tissue metabolomics can provide an improved understanding of the metabolic dysfunction associated with RIF. The identification of serum metabolic marker(s) in women with RIS may help with strategies of early therapeutic intervention, which may improve the chances of implantation significantly in women otherwise susceptible to IVF failure.

Abstract
OBJECTIVE To investigate the influence of dormant Mycobacterium tuberculosis on the expression of various endometrial receptivity markers and leukemia inhibitory factor (LIF)-signal transducers and activators of transcription 3 (STAT3) signaling pathway. Expression of endometrial receptivity markers and LIF-STAT3 signaling in in vitro decidualized human endometrial stromal cells (hESC) treated with 65 kDa mycobacterial heat shock protein (HSP65) is also explored. DESIGN A prospective study. SETTING Tertiary care hospital and reproductive health research unit. PATIENT(S) Endometrial tissue samples were collected from 38 women who tested positive for Mycobacterium tuberculosis and 30 normal women with proven fertility undergoing sterilization. In vitro decidualization of hESC was performed. INTERVENTION(S) Endometrial biopsies collected from all women during implantation window and treatment of hESC with HSP65. MAIN OUTCOME MEASURE(S) Measurement of various endometrial receptivity markers including αvβ3 integrin, E-cadherin, MECA-79, mucin-1, and pinopodes and LIF/LIFR-STAT3 signaling molecules expressed in the endometrium of women with dormant genital tuberculosis (GTB) during implantation window and measured also in HSP65-treated hESC. RESULT(S) Significantly reduced levels of endometrial receptivity markers LIF, LIFR, and pSTAT3 were observed in endometrium of women with dormant GTB as compared with controls. A similar trend was observed under in vitro conditions with decreased level of phosphorylated STAT3 in HSP65-treated hESC. However, no change in the expression of endometrial receptivity markers under in vitro conditions was observed. CONCLUSION(S) Our findings suggest that endometrium of women with dormant GTB is associated with poor receptivity, as evidenced by reduced receptivity markers and aberrant LIF-STAT3 signaling. In vitro treatment of hESC with HSP65 also confirms compromised endometrial decidualization.

Endometriosis is characterized by the presence of endometrial glands and stroma outside the uterine cavity. Conventional treatment modalities for endometriosis are unsatisfactory; therefore, there is a need to treat the underlying causes and mechanism. Oxidative stress, extracellular matrix degradation, and angiogenesis are associated with the pathogenesis of endometriosis. The anti-angiogenic and antioxidant properties of epigallocatechin gallate and the matrix metalloproteinase inhibitory activity of the antibiotic doxycycline are well established. However, epigallocatechin gallate and doxycycline have several limitations when used in their native forms. This motivated us to synthesize dual drug-loaded (epigallocatechin gallate and doxycycline) nanoparticles and check their therapeutic efficacy in mice with induced endometriosis. The synthesized nanoparticles displayed features of a promising drug-delivery system, such as small size, high encapsulation efficiency, controlled drug release, and low toxicity. The serum of endometriosis-induced mice and controls was assessed for various oxidative stress markers, matrix-degrading enzymes, and angiogenic markers before and after nanoparticle administration. Endometrial glands, stroma, and new microvessels were determined using histochemistry and immunohistochemistry. Treatment with dual drug-loaded nanoparticles markedly decreased oxidative stress, matrix metalloproteinase activity, and angiogenesis, as well as endometrial gland presence and microvessel density. Mitigation of endometriosis-related adverse effects further produced an improvement in the quality of oocytes, which is critical for successful pregnancy outcomes. Our observations suggest that owing to their combinatorial effect, poly(lactic-co-glycolic) acid nanoparticles loaded with epigallocatechin gallate and doxycycline in a single vehicle appear to be promising for the treatment of endometriosis.

Abstract
AIM To evaluate differences in uteroplacental blood flow and pregnancy outcome in women with idiopathic recurrent spontaneous miscarriage (IRSM) following administration of micronized vaginal progesterone and oral dydrogesterone. METHODS One hundred and thirty-three women (aged 23-40 years) who had had early miscarriages and spontaneous conception participated. Oral dydrogesterone (group A, n = 51) and micronized vaginal progesterone (group B, n = 50) were administrated for luteal support and compared. Pregnant women without history of recurrent miscarriage served as controls (group C, n = 32). The outcome measures consisted of endometrial blood flow parameters by Doppler indices and ongoing pregnancy rate. RESULTS Before progesterone supplementation, resistivity index (RI) and pulsatility index (PI) were found to be significantly higher in groups A and B as compared to controls. Although statistically not significant, end diastolic velocity (EDV) and systolic/diastolic (S/D) ratio was found to be superior in controls than IRSM women. Peak systolic velocity (PSV) was comparable between IRSM and non-IRSM groups. Following progesterone supplementation, groups A and B showed a highly significant reduction in RI, PI and an increase in EDV. A relative increase in the value of PSV was observed in group A as compared to group B. There was remarkable difference in S/D in both groups. Although not statistically significant, group C showed reduction in RI, PI, PSV, EDV and S/D ratio. Pregnancy salvage rates were higher in group A (92.0%) as compared to group B (82.3%). CONCLUSION Progesterone supplementation appears to lower vascular resistance in women with IRSM. Oral dydrogesterone appears to be equally effective in improving endometrial blood flow as compared with micronized progesterone.

Abstract
PURPOSE To investigate the role of genetic variations and expression alterations of BRCA1 and BRCA2 genes in the pathophysiology of endometriosis. METHODS A genetic association study was conducted in 573 endometriosis cases and 490 controls of Indian origin. We genotyped 13 selected promoter SNPs of BRCA1 gene and 2 selected promoter SNPs of BRCA2 gene by PCR-sequencing analysis. In addition, to better understand genetic contributions to the pathophysiology of endometriosis, the expression pattern of BRCA1 & 2 was analyzed in the eutopic endometria of endometriosis cases and controls by western-blot and immunohistochemical analysis. RESULTS Our results revealed significant association between BRCA1 rs71361504 (-/GTT) SNP and endometriosis risk in Indian women (P < 0.0001), while the remaining SNPs of both BRCA1 & 2 genes showed no difference between cases and controls. Western-blot and immunohistochemical analysis revealed significantly decreased BRCA1 expression levels in eutopic endometria of patients compared with controls (P < 0.05). Furthermore, nuclear BRCA1 was frequently lost compared with cytoplasmic BRCA1 in eutopic endometria of patients. Expression of BRCA2 did not differ between patients and controls. CONCLUSIONS BRCA1 rs71361504 SNP may modify the endometriosis risk in Indian women. In addition, decreased expression of BRCA1 may play an important role in the pathophysiology of endometriosis. The analysis of BRCA1 genetic variants and/or expression might help to identify patients at high risk for disease outcome.

Abstract
OBJECTIVE To report a live birth with in vitro fertilization (IVF) from a 50-year-old woman with homologous oocytes. DESIGN Case report. SETTING Referral center. PATIENT(S) A 50-year-old woman. INTERVENTION(S) IVF with fresh embryo transfer (ET). MAIN OUTCOME MEASURE(S) Live birth after IVF. RESULT(S) A 50-year-old woman conceived with her own oocytes by means of IVF. Three fresh embryos were transferred, resulting in a pregnancy and delivery by cesarean section at 35 weeks of a healthy male baby weighing 2,300 g. CONCLUSION(S) Extensive literature search suggests that this is the first case report of live birth in a 50-year-old woman after IVF-ET with her own oocytes. This is a very rare and unusual case that deviates from the norm and therefore warrants attention. In selected cases, assisted reproductive technology might be reasonable to try for a limited number of times with a woman's own oocytes.

Abstract
UNLABELLED Endometriosis is a common benign gynecological disease, characterized by proliferation of functional endometrial glands and stroma outside the uterine cavity. The present study involves investigation of alterations in the serum proteome of endometriosis patients compared to healthy controls using 2DE and 2D-DIGE combined with MALDI TOF/TOF-MS. Comparison of serum proteome of endometriosis patients and healthy subjects revealed 25 significant differentially expressed proteins. Gene ontology and network analysis, performed using PANTHER, DAVID, WebGestalt and STRING, revealed that the differentially expressed proteins are majorly involved in response to stimulus, immune system, metabolic, localization and cellular processes. For serum diagnostic marker identification, several robust statistical screening procedures were applied to identify the set of the most significant proteins responsible for successful diagnosis of different endometriosis stages. Partial least squares (PLS) based marker selection tool and orthogonal partial least squares-discriminant analysis (OPLS-DA) were used to identify the most significant proteins for disease prediction. Western blotting validation in a separate cohort of patients revealed that haptoglobin (HP), Ig kappa chain C region (IGKC), alpha-1B-glycoprotein (A1BG) can be considered effective serum protein markers for the diagnosis of Stage II, III and IV endometriosis. For diagnosis of Stage I, only IGKC and HP seemed promising. BIOLOGICAL SIGNIFICANCE Globally, about 12 in 100 women of reproductive age are diagnosed with endometriosis. The pathogenesis of the disease still remains unclear, leading to non-specific therapeutic approaches for disease management. Moreover, there is a delay of 8-12years in correct diagnosis after the initial onset of symptoms leading to a considerable impact on the woman's lifestyle. Also, the gold standard for diagnosis of endometriosis, laparoscopy, is an invasive procedure. The value of a noninvasive or semi-invasive diagnostic test for endometriosis with easily accessible fluids such as plasma, serum, urine, and saliva is, therefore, rightfully recognized. The present study is expected to considerably improve the understanding of the disease pathogenesis along with improved diagnostics and therapeutic approaches leading to better management of the disease.

Abstract
Though various advantages associated with the use of letrozole as an ovulation inducing drug are documented, there is inadequate information regarding its effect on endometrial receptivity. Expression of endometrial receptivity markers including αvβ3 integrin, L-selectin, LIF, and pinopods during the implantation window in infertile women stimulated with letrozole or clomiphene citrate (CC), and spontaneous cycles is investigated. A total of 36 women were included in the study out of which 16 women were diagnosed with primary unexplained infertility and the other 20 women with severe oligoasthenozoospermic/azoospermic male partners. Both groups were sub-divided into three groups; women stimulated with letrozole, or with CC, and the third group was allowed to ovulate spontaneously (natural cycles). Women having natural cycles and not given any drug were considered as controls. Once ovulation was confirmed by ultrasonography, endometrial samples were collected on the seventh day post-ovulation and analyzed. In women with unexplained infertility treated with letrozole and CC, epithelial and stromal expression of αvβ3 integrin, L-selectin, leukemia inhibitory factor (LIF), and pinopod formation was found to be significantly higher as compared to controls. Expression of these receptivity markers was found to be comparable amongst the letrozole, CC, and control groups in women with severe oligoasthenozoospermic/azoospermic male partners. Cell cycle analysis showed similar cell cycle phase fractions on comparing the CC and the letrozole groups. Stimulation with letrozole and CC appears to enhance endometrial receptivity in women with unexplained infertility. However, letrozole and CC did not have any significant effect on the endometrial receptivity markers of women with severe oligoasthenozoospermic/azoospermic male partners.

Abstract
Poor endometrial perfusion during implantation window is reported to be one of the possible causes of idiopathic recurrent spontaneous miscarriage (IRSM). We have tested the hypothesis that certain angiogenic and vasoactive factors are associated with vascular dysfunction during implantation window in IRSM and, therefore, could play a contributory role in making the endometrium unreceptive in these women. This is a prospective case-controlled study carried out on 66 women with IRSM and age and BMI matched 50 fertile women serving as controls. Endometrial expression of pro-inflammatory (IL-1β, TNF-α, IFN-γ, TGF-β1), anti-inflammatory (IL-4, -10), angiogenesis-associated cytokines (IL-2, -6, -8), angiogenic and vasoactive factors including prostaglandin E2 (PGE2), vascular endothelial growth factor (VEGF), endothelial nitric oxide synthase (eNOS), nitric oxide (NO) and adrenomedullin (ADM) were measured during implantation window by ELISA. Subendometrial blood flow (SEBF) was assessed by color Doppler ultrasonography. Multivariate analysis was used to identify the significant factor(s) responsible for vascular dysfunction in IRSM women during window of implantation and further correlated with vascular dysfunction. Endometrial expression of pro-inflammatory cytokines and PGE2 were up-regulated and anti-inflammatory and angiogenesis-associated cytokines down-regulated in IRSM women as compared with controls. Further, the angiogenic and vasoactive factors including VEGF, eNOS, NO and ADM were found to be down-regulated and SEBF grossly affected in these women. Multivariate analysis identified IL-10, followed by VEGF and eNOS as the major factors contributing towards vascular dysfunction in IRSM women. Moreover, these factors strongly correlated with blood flow impairment. This study provides an understanding that IL-10, VEGF and eNOS are the principal key components having a contributory role in endometrial vascular dysfunction in women with IRSM. Down-regulation of these factors is also associated with impaired endometrial perfusion which possibly makes the endometrium unreceptive that may eventually cause early pregnancy loss.

STUDY QUESTION Are mutations in the phosphatase and tensin homolog deleted on chromosome 10 (PTEN) gene associated with endometriosis? SUMMARY ANSWER Loss of heterozygosity (LOH) at the 10q23.3 locus, PTEN somatic mutations and changes in the levels and distribution of proteins in the PTEN-PI3K/Akt signal transduction pathway are associated with endometriosis. WHAT IS KNOWN ALREADY Endometriosis has a strong genetic basis. Recent genome-wide association and linkage studies have reported a significant association of endometriosis with 7p15.2, 9p21 and 10q23-26 loci. PTEN, which maps to 10q23.3, acts as a tumor suppressor gene through the action of its phosphatase protein product, phosphatase and tensin homolog (PTEN). This phosphatase is involved in the regulation of the cell cycle, and mutations of PTEN are a step in the development of many cancers. STUDY DESIGN, SIZE, DURATION A total of 1252 subjects of Indian origin (endometriosis patients = 752; controls = 500) were recruited to participate in this case-control study. Recruitment took place from 2001 to 2009 at Institute of Reproductive Medicine (IRM), Kolkata, India; Infertility Institute and Research Centre (IIRC), Secundrabad, India and Vasavi Medical and Research Centre, Hyderabad, India. PARTICIPANTS/MATERIALS, SETTING, METHODS LOH on 10q, 9p and 7p was analyzed in analogous ectopic-eutopic endometria along with blood samples from 32 advanced stage endometriosis patients by PCR-GeneScan analysis. Genotyping of PTEN was carried out on genomic DNA of analogous ectopic-eutopic endometria (n = 32) as well as blood samples from 720 patients and 500 controls by PCR-sequencing analysis to explore somatic and germ-line mutations, respectively. The levels and distribution of PTEN, p-Akt, p-Bad and p27 were analyzed in the eutopic endometria of patients (n = 5) and controls (n = 5) using western-blot and immunohistochemistry. MAIN RESULTS AND THE ROLE OF CHANCE PCR-GeneScan analysis revealed a higher LOH frequency at 10q23.3 (84.4%) compared with other loci analyzed, hence we focused our attention on PTEN. PCR-sequencing analysis revealed seven novel somatic mutations and 23 germ-line polymorphisms in patients. Among somatic mutations, a frame-shift insertion at 10:89692992-89692993 (in the functionally important N-terminal phosphatase domain of PTEN) occurred in 11 of the 32 ectopic endometria. Western-blot and immunohistochemical analysis revealed decreased PTEN and increased p-Akt and p-Bad levels in eutopic endometria of patients compared with controls (all comparisons, P < 0.0001). Furthermore, PTEN loss was more frequent in the nucleus than in the cytoplasm. Expression of p27 did not differ between patients and controls. LIMITATIONS, REASONS FOR CAUTION Protein analysis was performed in eutopic endometrial samples from only a small number of patients and controls. In future investigations, a larger sample size should be used and the role of the other genes involved in the PTEN-PI3K/Akt signal transduction pathway should be analyzed. WIDER IMPLICATIONS OF THE FINDINGS Our findings revealed a possible involvement of the PTEN-PI3K/Akt-Bad axis in the pathogenesis of endometriosis, which may facilitate the discovery of suitable pathway inhibitors for disease treatment. STUDY FUNDING/COMPETING INTEREST(S) This study was supported by grants from the Science & Engineering Research Board (SERB), India (Lr No: SR/FT/LS-188/2009) to BM. The authors have no competing interests to declare.
