Abstract
Purpose: To determine the impact of dose-dense chemotherapy administration on ovarian reserve in women undergoing treatment for breast cancer. Patients and Methods: We conducted a retrospective cohort study of reproductive age women who underwent dose-dense chemotherapy regimens with doxorubicin hydrochloride and cyclophosphamide with or without paclitaxel for a new diagnosis of breast cancer. We compared pre- and post-treatment serum antimullerian hormone (AMH) levels and assessed changes in AMH over time. Results: Fifty-seven patients met inclusion criteria. Median pre-treatment AMH was 2.9 ng/mL, whereas post-treatment AMH was 0.1 ng/mL, demonstrating a dramatic reduction in AMH levels after treatment with a dose-dense regimen. This change was independent of age and was sustained over 12 months from treatment completion. Conclusions: Dose-dense chemotherapy regimens for breast cancer lead to marked and sustained decreases in AMH irrespective of patient age.

Abstract
RESEARCH QUESTION What should be the optimal route of luteal support in programmed frozen embryo transfer (FET) cycles? DESIGN This was a randomized, parallel, phase IV pilot trial with three groups of women undergoing FET along with hormone replacement therapy for endometrial preparation at a tertiary private IVF centre (NCT03948022). Women with at least one autologous cryopreserved blastocyst were included. After preparing the endometrium with oestradiol, 151 women were randomly assigned to one of the following three progesterone arms before embryo transfer: oral (10 mg) dydrogesterone (DYD), total daily dose 40 mg (n = 52); 8% (90 mg) progesterone vaginal gel (VAG), total daily dose 180 mg (n = 55); or intramuscular progesterone (IMP) 50 mg/ml in oil, total daily dose 100 mg (n = 44). One or two vitrified-warmed blastocysts were transferred after 5 days' progesterone support. RESULTS Baseline demographic features and embryological data were comparable among the groups. Ongoing pregnancy rates (40.4%, 38.2% and 45.5% in the DYD, VAG and IMP arms; P = 0.76) and live birth rates (40.4%, 38.2% and 43.2% in the DYD, VAG and IMP arms, P = 0.61) were statistically similar. Biochemical pregnancy rates and clinical miscarriage rates were also statistically similar among the groups. Significantly more patients with at least one side effect and moderate-to-severe side effects were documented in the IMP arm than the other groups (P < 0.001). CONCLUSIONS Treatment with 40 mg/day oral DYD, 180 mg/day progesterone VAG gel or 100 mg/day IMP revealed similar reproductive outcomes in programmed FET cycles. Side effects were significantly more frequent in the IMP arm.

Abstract
Recent advances in developing polygenic scores have made it possible to screen embryos for common, complex conditions and traits. Polygenic embryo screening (PES) is currently offered commercially, and though there has been much recent media and academic coverage, reproductive specialists' points of view have not yet been prominent in these discussions. We convened a roundtable of multidisciplinary experts, including reproductive specialists to discuss PES and its implications. In this Opinion, we describe four clinically relevant issues associated with the use of PES that have not yet been discussed in the literature and warrant consideration.

Abstract
Yolk-sac tumors account for about 20% of ovarian germ cell tumors and occur predominantly in women below 35 years of age. Modern evidence-based treatment strategies have ensured long term post-treatment survival, but with increased survival, attention has been turned to an urgent need for developing fertility sparing treatment strategies. In this report we describe the successful treatment of a young woman who was able to conceive and deliver two children, in spite of the loss of one ovary two years prior to being diagnosed with an ovarian yolk-sac tumor on the remaining ovary.

Abstract
The differentiation of endometrial stromal cells into decidual cells, termed decidualization, is an integral step in the establishment of pregnancy. The mitogen-activated protein kinase homolog, WNK lysine deficient protein kinase 1 (WNK1), is activated downstream of epidermal growth factor receptor during decidualization. Primary human endometrial stromal cells (HESCs) were subjected to small interfering RNA knockdown of WNK1 followed by in vitro decidualization. This abrogated expression of the decidual marker genes, insulin like growth factor binding protein 1 (IGFBP1) and prolactin (PRL), and prevented adoption of decidual cell morphology. Analysis of the WNK1-dependent transcriptome by RNA-Seq demonstrated that WNK1 regulates the expression of 1858 genes during decidualization. Gene ontology and upstream regulator pathway analysis showed that WNK1 regulates cell migration, differentiation, and proliferation. WNK1 was required for many of the gene expression changes that drive decidualization, including the induction of the inflammatory cytokines, C-C motif chemokine ligand 8 (CCL8), interleukin 1 beta (IL1B), and interleukin 15 (IL15), and the repression of transforming growth factor-beta (TGF-beta) pathway genes, including early growth response 2 (EGR2), SMAD family member 3 (SMAD3), integrin subunit alpha 2 (ITGA2), integrin subunit alpha 4 (ITGA4), and integrin subunit beta 3 (ITGB3). In addition to abrogating decidualization, WNK1 knockdown decreased the migration and proliferation of HESCs. Furthermore, mitogen-activated protein kinase 7 (MAPK7), a known downstream target of WNK1, was activated during decidualization in a WNK1-dependent manner. Small interfering RNA knockdown of MAPK7 demonstrated that MAPK7 regulates a subset of WNK1-regulated genes and controls the migration and proliferation of HESCs. These results indicate that WNK1 and MAPK7 promote migration and proliferation during decidualization and regulate the expression of inflammatory cytokines and TGF-beta pathway genes in HESCs.

Abstract
Premature ovarian failure is a devastating diagnosis for reproductive-aged women. The diagnosis is relatively easy. However, it has serious health consequences, including psychological distress, infertility, osteoporosis, autoimmune disorders, ischemic heart disease, and increased risk for mortality. Management should be initiated immediately to prevent long-term consequences. Estrogen therapy is the mainstay of management. Postmenopausal estrogen therapy studies should not be used to determine the risks of treatment in these young women.

Abstract
PURPOSE The purpose of this paper is to determine whether antimullerian hormone (AMH) levels were associated with BMI in patients with diagnosed infertility, and more specifically, in patients with polycystic ovarian syndrome (PCOS). METHODS A retrospective cohort study reviewed all females who presented to the clinical investigators' practice between November 2011 and March 2013. The following data was retrieved from the medical record: (1) AMH level, (2) age, (3) BMI, (4) ethnicity, and (5) if infertile, etiology of infertility. RESULTS AMH levels were available for 489 women. Of these, 104 were diagnosed with PCOS. Overall, there was no association between BMI and AMH (r -0.04, p > 0.05). On the other hand, in the women with PCOS, there was a significant association between BMI and AMH (r -0.31, p < 0.01). CONCLUSIONS BMI was not associated with AMH levels in the general population of infertile women or in patients without PCOS. However, BMI appeared to be significantly and inversely correlated with AMH in women with PCOS.

Abstract
Decidualization is a complex process involving cellular proliferation and differentiation of the endometrial stroma that is required to establish and support pregnancy. Progesterone acting via its nuclear receptor, the progesterone receptor (PGR), is a critical regulator of decidualization and is known to interact with certain members of the activator protein-1 (AP-1) family in the regulation of transcription. In this study, we identified the cistrome and transcriptome of PGR and identified the AP-1 factors FOSL2 and JUN to be regulated by PGR and important in the decidualization process. Direct targets of PGR were identified by integrating gene expression data from RNA sequencing with the whole-genome binding profile of PGR determined by chromatin immunoprecipitation followed by deep sequencing (ChIP-seq) in primary human endometrial stromal cells exposed to 17β-estradiol, medroxyprogesterone acetate, and cAMP to promote in vitro decidualization. Ablation of FOSL2 and JUN attenuates the induction of 2 decidual marker genes, IGFBP1 and PRL. ChIP-seq analysis of genomic binding revealed that FOSL2 is bound in proximity to 8586 distinct genes, including nearly 80% of genes bound by PGR. A comprehensive assessment of the PGR-dependent decidual transcriptome integrated with the genomic binding of PGR identified FOSL2 as a potentially important transcriptional coregulator of PGR via direct interaction with regulatory regions of genes actively regulated during decidualization.

Abstract
The forkhead box O1A (FOXO1) is an early-induced target of the protein kinase A pathway during the decidualization of human endometrial stromal cells (HESCs). In this study we identified the cistrome and transcriptome of FOXO1 and its role as a transcriptional regulator of the progesterone receptor (PR). Direct targets of FOXO1 were identified by integrating RNA sequencing with chromatin immunoprecipitation followed by deep sequencing. Gene ontology analysis demonstrated that FOXO1 regulates a subset of genes in decidualization such as those involved in cancer, p53 signaling, focal adhesions, and Wnt signaling. An overlap of the FOXO1 and PR chromatin immunoprecipitation followed by deep sequencing intervals revealed the co-occupancy of FOXO1 in more than 75% of PR binding intervals. Among these intervals were highly enriched motifs for the interferon regulatory factor member 4 (IRF4). IRF4 was determined to be a genomic target of both FOXO1 and PR and also to be differentially regulated in HESCs treated with small interfering RNA targeting FOXO1 or PR prior to decidualization stimulus. Ablation of FOXO1 was found to abolish binding of PR to the shared binding interval downstream of the IRF4 gene. Finally, small interfering RNA-mediated ablation of IRF4 was shown to compromise morphological transformation of decidualized HESCs and to attenuate the expression of the decidual markers IGFBP1, PRL, and WNT4. These results provide the first evidence that FOXO1 is functionally required for the binding of PR to genomic targets. Most notably, FOXO1 and PR are required for the regulation of IRF4, a novel transcriptional regulator of decidualization in HESCs.

Abstract
Recent data from human and mouse studies strongly support an indispensable role for steroid receptor coactivator-2 (SRC-2)-a member of the p160/SRC family of coregulators-in progesterone-dependent endometrial stromal cell decidualization, an essential cellular transformation process that regulates invasion of the developing embryo into the maternal compartment. To identify the key progesterone-induced transcriptional changes that are dependent on SRC-2 and required for endometrial decidualization, we performed comparative genome-wide transcriptional profiling of endometrial tissue RNA from ovariectomized SRC-2(flox/flox) (SRC-2(f/f) [control]) and PR(cre/+)/SRC-2(flox/flox) (SRC-2(d/d) [SRC-2-depleted]) mice, acutely treated with vehicle or progesterone. Although data mining revealed that only a small subset of the total progesterone-dependent transcriptional changes is dependent on SRC-2 (∼13%), key genes previously reported to mediate progesterone-driven endometrial stromal cell decidualization are present within this subset. Along with providing a more detailed molecular portrait of the decidual transcriptional program governed by SRC-2, the degree of functional diversity of these progesterone mediators underscores the pleiotropic regulatory role of SRC-2 in this tissue. To showcase the utility of this powerful informational resource to uncover novel signaling paradigms, we stratified the total SRC-2-dependent subset of progesterone-induced transcriptional changes in terms of novel gene expression and identified transcription factor 23 (Tcf23), a basic-helix-loop-helix transcription factor, as a new progesterone-induced target gene that requires SRC-2 for full induction. Importantly, using primary human endometrial stromal cells in culture, we demonstrate that TCF23 function is essential for progesterone-dependent decidualization, providing crucial translational support for this transcription factor as a new decidual mediator of progesterone action.

Abstract
Abstract
An important late effect among female survivors of childhood cancer is treatment-related ovarian damage and impaired fertility. While chemotherapy and radiation therapy are associated with impaired fertility, few other risk factors have been identified. Furthermore, little is known about the role of genetic susceptibility to these late effects. Objective: As Anti-Müllerian Hormone (AMH) is a demonstrated marker of ovarian reserve; our objective was to identify clinical and genetic predictors of AMH levels in female survivors of childhood cancer. Methods: Female childhood cancer survivors (n = 181) were recruited from the Texas Children's Cancer Center Long Term Survivor Program (LTSP). AMH (ng/mL) was measured using an enzyme-linked immunosorbent assay. Information on age at diagnosis and enrollment, race, ethnicity, cancer diagnosis, pelvic radiation, and use of alkylating agents was abstracted from medical records. The following single nucleotide polymorphisms (SNPs) were selected based on known or suspected function: AMHR2 rs2002555; CYP2C9*4 rs56165452; CYP2C19*2 rs4244285; and CYP2C19*3 rs4986893. SNPs were genotyped using TaqMan assays. Linear regression was used to determine the association between selected factors and AMH levels. As AMH levels were not normally distributed, the dependent variable was expressed as log10(AMH+1). Results: The mean age at enrollment in the LTSP was 12.4 years. The most common cancer diagnosis was acute lymphoblastic leukemia (47.2%), and a substantial proportion of the population was Hispanic (41.0%). The following variables were significantly associated with lower AMH levels: pelvic radiation (beta = −0.61, P < 0.001) and treatment with alkylating agents (beta = −0.09, P = 0.04). Age at enrollment was associated with higher AMH levels (beta = 0.01, P = 0.04). Hispanic ethnicity was marginally associated with lower AMH levels (beta = −0.08, P = 0.08). There were no significant genetic associations. Conclusions: In one of the largest studies of its kind, our results confirm previous associations between treatment-related factors and ovarian damage. While the SNPs evaluated were not predictive of AMH levels, more work is needed to explain why some survivors experience impaired fertility, while others do not, despite similar therapy.

Abstract
Early embryo miscarriage is linked to inadequate endometrial decidualization, a cellular transformation process that enables deep blastocyst invasion into the maternal compartment. Although much of the cellular events that underpin endometrial stromal cell (ESC) decidualization are well recognized, the individual gene(s) and molecular pathways that drive the initiation and progression of this process remain elusive. Using a genetic mouse model and a primary human ESC culture model, we demonstrate that steroid receptor coactivator-2 (SRC-2) is indispensable for rapid steroid hormone-dependent proliferation of ESCs, a critical cell-division step which precedes ESC terminal differentiation into decidual cells. We reveal that SRC-2 is required for increasing the glycolytic flux in human ESCs, which enables rapid proliferation to occur during the early stages of the decidualization program. Specifically, SRC-2 increases the glycolytic flux through induction of 6-phosphofructo-2-kinase/fructose-2, 6-bisphosphatase 3 (PFKFB3), a major rate-limiting glycolytic enzyme. Similarly, acute treatment of mice with a small molecule inhibitor of PFKFB3 significantly suppressed the ability of these animals to exhibit an endometrial decidual response. Together, these data strongly support a conserved mechanism of action by which SRC-2 accelerates the glycolytic flux through PFKFB3 induction to provide the necessary bioenergy and biomass to meet the demands of a high proliferation rate observed in ESCs prior to their differentiation into decidual cells. Because deregulation of endometrial SRC-2 expression has been associated with common gynecological disorders of reproductive-age women, this signaling pathway, involving SRC-2 and PFKFB3, promises to offer new clinical approaches in the diagnosis and/or treatment of a non-receptive uterus in patients presenting idiopathic infertility, recurrent early pregnancy loss, or increased time to pregnancy. Failure of an embryo to correctly implant into the endometrium is a common cause of pregnancy failure or early embryo miscarriage. Although advances in our understanding of oocyte and embryo development have significantly increased pregnancy success rates, these rates remain unacceptably low due in part to an endometrium that is unreceptive to embryo implantation. Using experimental mouse genetics and a primary human cell culture model, we show here that the development of a receptive endometrium requires steroid receptor coactivator-2, a factor which modulates the response of an endometrial cell to the pregnancy hormone, progesterone. Specifically, we show that SRC-2 increases progesterone-dependent glycolysis in the endometrial cell to provide energy and biomolecules for the next round of cell division. For an endometrium to be receptive to embryo implantation, specific endometrial cells (termed stromal cells) need to divide and numerically increase just prior to development of the receptive state. Therefore, SRC-2 is critical for the metabolic reprogramming of the endometrium to a receptive state, which provides the pretext for considering this factor and its metabolic targets in the design of future clinical approaches to diagnose and therapeutically treat those women at a high risk for early pregnancy loss.

Abstract
Successful pregnancy requires coordination of an array of signals and factors from multiple tissues. One such element, the liver receptor homolog-1 (Lrh-1, NR5A2), is an orphan nuclear receptor that regulates metabolism and hormone synthesis1. It is strongly expressed in granulosa cells of ovarian follicles and in the corpus luteum of rodents2 and humans. Germline ablation of the Lrh-1 gene in mice is embryo-lethal at gastrulation3. Depletion of Lrh-1 in the ovarian follicle demonstrates that it regulates genes required for both steroid synthesis and ovulation4. To study the effects of Lrh-1 on mouse gestation, we disrupted its expression in the corpus luteum, resulting in luteal insufficiency. Hormone replacement permitted embryo implantation but was followed by gestational failure with impaired endometrial decidualization, compromised placental formation, fetal growth retardation, and fetal death. Lrh-1 is expressed in the mouse and human endometrium. In a human model of primary culture of endometrial stromal cells, depletion of Lrh-1 by siRNA abrogated decidualization. These findings demonstrate that Lrh-1 is necessary for maintenance of the corpus luteum, for promotion of decidualization and for placental formation. It therefore plays multiple, indispensible roles in establishing and sustaining pregnancy.

Abstract
We tested several approaches that can be used to preserve sperm attributes and the objective biochemical markers of sperm maturity and function for assessment in a remote centralized laboratory after overnight shipping of semen samples. Addition of phenyl-methyl-sulfonyl-fluoride (PMSF) to a final concentration of 20 microg/mL semen at 4 degrees C has preserved sperm concentrations and HspA2 isoform ratios, even at room temperature, simulating a shipping delay in moderate ambient temperatures. Regarding the attributes of individual spermatozoa, the patterns of CK-immunocytochemistry (demonstrates cytoplasmic retention in diminished-maturity spermatozoa); aniline blue staining pattern (tests chromatin maturity); sperm shape assessed by both Kruger strict morphology and computer assisted morphometry; and sperm DNA integrity, as tested by DNA nick translation, all remained unchanged. Thus, the PMSF-4 degrees C conditions preserved sperm concentrations and the cytoplasmic and nuclear biomarkers of sperm cellular maturity and function for next-day analysis. This shipping method will facilitate the early detection of subtle changes in semen quality that can affect sperm function, even when there has been no decline in sperm concentrations to signal possible toxic effects. Furthermore, sample preservation will enable investigators to evaluate semen for toxicology studies and for diagnosis of male infertility from remote locations. Home collection of semen should enhance study participation, and semen assessment in centralized laboratories will address concerns regarding interlaboratory variations and quality control.

Abstract
Endometriosis is considered to be an estrogen-dependent inflammatory disease, but its etiology is unclear. Thus far, a mechanistic role for steroid receptor coactivators (SRCs) in the progression of endometriosis has not been elucidated. An SRC-1-null mouse model reveals that the mouse SRC-1 gene has an essential role in endometriosis progression. Notably, a previously unidentified 70-kDa SRC-1 proteolytic isoform is highly elevated both in the endometriotic tissue of mice with surgically induced endometriosis and in endometriotic stromal cells biopsied from patients with endometriosis compared to normal endometrium. Tnf⁻/⁻ and Mmp9⁻/⁻ mice with surgically induced endometriosis showed that activation of tumor necrosis factor a (TNF-α)-induced matrix metallopeptidase 9 (MMP9) activity mediates formation of the 70-kDa SRC-1 C-terminal isoform in endometriotic mouse tissue. In contrast to full-length SRC-1, the endometriotic 70-kDa SRC-1 C-terminal fragment prevents TNF-α-mediated apoptosis in human endometrial epithelial cells and causes the epithelial-mesenchymal transition and the invasion of human endometrial cells that are hallmarks of progressive endometriosis. Collectively, the newly identified TNF-α-MMP9-SRC-1 isoform functional axis promotes pathogenic progression of endometriosis.

Abstract
OBJECTIVE: The objective was to evaluate the relationship between endometrial thickness on the day of human chorionic gonadotropin administration and pregnancy outcome in in vitro fertilization cycles. DESIGN: This was a systematic review and meta-analysis. MATERIALS AND METHODS: We identified 484 articles using Cochrane library, PubMed, Web of Science, and Embase searches with various key words including endometrial thickness, pregnancy, assisted reproductive technology, endometrial pattern, and in vitro fertilization. A total of 14 studies with data on endometrial thickness and outcome were selected, representing 4922 cycles (2204 pregnant and 2718 nonpregnant). The meta-analysis with a random effects model was performed using comprehensive meta-analysis software. We calculated the standardized mean difference, odds ratio (OR), and 95% confidence intervals (CIs). RESULTS: There was a significant difference in the mean endometrial thickness between pregnant and nonpregnant groups (P<0.001), with a standardized mean difference of 0.4 mm (95% CI 0.22–0.58). The OR for pregnancy was 1.40 (95% CI 1.24–1.58). CONCLUSIONS: The mean endometrial thickness was significantly higher in pregnant women compared to nonpregnant. The mean difference between two groups was <1 mm which may not be clinically meaningful. Although there may be a relationship between endometrial thickness and pregnancy, implantation potential is probably more complex than a single ultrasound measurement can determine.

Abstract
OBJECTIVE To analyze DNA from women with premature ovarian failure (POF) for genome-wide copy-number variations (CNVs), focusing on novel autosomal microdeletions. DESIGN Case-control genetic association study. SETTING Department of Obstetrics and Gynecology, Baylor College of Medicine, Houston, Texas. PATIENT(S) Of 89 POF patients, eight experienced primary amenorrhea and 81 exhibited secondary amenorrhea before age 40 years. INTERVENTION(S) Genomic DNA from peripheral blood samples was analyzed for CNVs using high-resolution single-nucleotide polymorphism (SNP) arrays. MAIN OUTCOME MEASURE(S) Identification of novel CNVs in 89 POF cases, using the Database of Genomic Variants as a control population. RESULT(S) A total of 198 autosomal CNVs were detected by SNP arrays, ranging in size from 0.1 Mb to 3.4 Mb. These CNVs (>0.1 Mb) included 17 novel microduplications and seven novel microdeletions, six of which contained the coding regions 8q24.13, 10p15-p14, 10q23.31, 10q26.3, 15q25.2, and 18q21.32. Most of the novel CNVs were derived from autosomes rather than the X chromosome. CONCLUSION(S) The present pilot study revealed novel microdeletions/microduplications in women with POF. Two novel microdeletions caused haploinsufficiency for SYCE1 and CPEB1, genes known to cause ovarian failure in knockout mouse models. Chromosomal microarrays may be a useful adjunct to conventional karyotyping when evaluating genomic imbalances in women with POF.

Abstract
OBJECTIVES The authors aimed to provide evidence for a major gene effect on blood pressure across normal pregnancy. METHODS Blood pressure measurements from 265 patients of Mexican descent derived from medical records were grouped into 4-week blocks by gestational age. Analyses of normality in the distribution of measurements for each block were applied to determine the emergence of a major gene effect and identify the gestational age at which that occurs. Systolic and diastolic blood pressures were used to determine median and percentile values for each block. RESULTS There was a shift from normal to non-normal distribution in systolic blood pressure between 12 and 15 weeks' gestation. This was similar for diastolic blood pressure. Median blood pressure values increased from 10 to 40 weeks' gestation without evidence of a decline during the second trimester of pregnancy. CONCLUSION Genetic regulation of blood pressure across pregnancy is dynamic, as demonstrated by the emergence of a major gene effect beginning around 12 weeks' gestation.

Abstract
Uterine leiomyomas (ULs) are benign monoclonal tumors originating from myometrial tissue in the uterus. Genetic pathways that lead to myometrial transformation into leiomyomas are largely unknown. Approximately 40% of ULs are karyotypically abnormal by G-banding; however, the remaining 60% of leiomyomas do not contain cytogenetically visible genomic rearrangements. Recent technological advances such as array based comparative genomic hybridization (array CGH) and dense single nucleotide polymorphism (SNP) arrays have enabled genome-wide scanning for genomic rearrangements missed by karyotype banding analysis. In the current study, we employed a high resolution SNP microarray on 16 randomly selected ULs and normal myometrium samples to detect submicroscopic (<5 Mb) chromosomal aberrations. The SNP array identified gene dosage changes in 56% of the fibroids (9/16), 25% of which (4/16) had aberrations >5 Mb, whereas 31% of which (5/16) contained only submicroscopic copy number changes (<5 Mb). We corroborated 3/5 submicroscopic changes using quantitative PCR, meaning that ultimately, 19% of our samples (3/16) were found to contain only submicroscopic changes. Novel submicroscopic aberrations on chromosomal segments 1q42.13, 11q13.1 and 13q12.13 and large, previously unreported deletions on 15q11.2-q23, 17p-q21.31 and 22q12.2-q12.3 were identified. Previously reported deletions on 1p, 3q, 7q, 13, and chromosome 14q were also noted. RHOU, MAP3K11 and WASF3 gene copy numbers were changed in the subset of leiomyomas with submicroscopic aberrations, and these genes have previously been implicated in tumorigenesis. Our findings support the hypothesis that a significant fraction of ULs without visible cytogenetic changes harbor submicroscopic genomic rearrangements which may in turn contribute to transformation of normal myometrial tissue into leiomyomas.

Abstract
Uterine fibroid is the most common tumor of female reproductive organs. The role of relaxin signaling in leiomyoma development was analyzed. We used 23 matched pairs of leiomyoma and normal myometrium samples to compare the expression of relaxin family peptide receptors RXFP1 and RXFP2, caveolin 1, desmin, and steroid receptors and their cofactors, NCOR1 and NCOR2. The expression of RXFP1, evaluated by quantitative reverse transcription-PCR, was downregulated in fibroid tissues. Relaxin or insulin-like peptide 3 treatment suppressed transforming growth factor beta-induced phosphorylation of SMAD2 in rat leiomyoma ELT-3 cells in vitro, suggesting a possible involvement of relaxins in the etiology of leiomyoma.

Abstract
The LHX8 (LIM homeobox 8) gene encodes a LIM homeodomain transcriptional regulator that is preferentially expressed in germ cells and critical for mammalian oogenesis. The authors investigated whether nucleotide changes were present in the LHX8 gene of Caucasian women with premature ovarian failure (POF), as compared with control women. When the authors sequenced 95 Caucasian women with POF, they discovered two novel single-nucleotide polymorphisms (SNPs) in intron 3 (c.769+10G>T) and 3' untranslated region (c.1787A>G) of the LHX8 gene. These polymorphisms also were found in controls (n = 94), at frequencies that were not statistically different from those in POF women. Mutations in the LHX8 exons are uncommon in Caucasian women with POF.

Abstract
In mouse, XY embryos are committed to the male sex determination pathway after the transient expression of the Y-linked Sry gene in the Sertoli cell lineage between 10.5 and 12.5 dpc. In the C57BL/6J strain, male sex determination program can be modulated by some autosomal genes. The C57BL/6J alleles at these autosomal loci can antagonize male sex determination in combination with specific Sry alleles. In this report, the authors have identified an effect of these C57BL/6J specific alleles in combination with a mutated Sox9 allele, Sox9(Ods). Authors report the mapping of three of these genetic loci on mouse chromosome 5 and 10 in a backcross of the Ods mutation to the C57BL/6J background. Our study confirms the importance of the strain C57BL/6J for the investigation of the genetic mechanisms that control sex determination.

Abstract
We screened growth differentiation factor 9 coding regions for mutations in a Chinese sample of 100 women with premature ovarian failure and discovered four novel single-nucleotide polymorphisms: c.436C>T (p.Arg146Cys), c.588A>C (silent), c.712A>G (p.Thr238Ala), and c.1283G>C (p.Ser428Thr). Nonsynonymous single-nucleotide polymorphisms c.436C>T and c.1283G>C were also detected in the control population. The c.712A>G perturbation results in a missense mutation (p.Thr238Ala) and was not present in any of 96 controls. Substitution of the hydrophobic amino acid residue alanine for hydrophilic threonine may disrupt growth differentiation factor 9 function.

Abstract
NANOS3 encodes an RNA-binding protein and has a conserved function in germ cell development. Our objective was to investigate whether mutations in NANOS3 were present in Chinese and Caucasian women with premature ovarian failure. A known synonymous single-nucleotide polymorphism (rs 2016163) in exon 1 was identified through sequencing 80 Chinese and 88 Caucasian women with premature ovarian failure. No additional single-nucleotide polymorphisms or mutations were found in exons encoding for NANOS3. Our findings suggest that mutations in NANOS3 exons are rare in both Chinese and Caucasian women with premature ovarian failure.

Abstract
OBJECTIVE To determine whether perturbations of the growth differentiating factor-9 (GDF9) gene are associated with premature ovarian failure (POF). DESIGN Mutational analysis of the GDF9 gene in 61 women with POF. SETTING Academic institution. PATIENT(S) Sixty-one women with POF; 60 control women. INTERVENTION(S) Peripheral blood sampling, genomic DNA extraction, mutational screening, and DNA sequencing. MAIN OUTCOME MEASURE(S) Genetic perturbations in GDF9 that are associated with POF. RESULT(S) A single missense mutation, substitution of a cytosine residue with thymidine in exon 1 of GDF9, was found in a white woman in whom POF developed at age 22. This mutation occurred in a highly conserved proprotein region and resulted in replacement of a nonpolar amino acid (proline) with a polar amino acid (serine) at position 103. Neither 60 control women nor 60 other women with POF demonstrated this genetic perturbation. Exon 2 showed only previously recognized single nucleotide polymorphisms. CONCLUSION(S) GDF9 mutations may be one explanation for POF, albeit uncommon.

Abstract
OBJECTIVE To test a newly invented intracytoplasmic sperm injection (ICSI) sperm selection method based on sperm hyaluronic acid (HA) binding. DESIGN Comparison of chromosomal disomy and diploidy frequencies in sperm arising from semen and in HA-bound sperm. SETTING Academic andrology laboratory. PATIENT(S) Men presenting for semen analysis. INTERVENTION(S) Washed sperm fractions of 32 semen samples were applied to Petri dishes or glass slides coated with immobilized HA. The unbound sperm were rinsed gently, and the HA-bound sperm were removed with an ICSI pipette. The control sperm population was the unselected sperm. Both HA-selected and unselected sperm were treated with fluorescence in situ hybridization with centromeric probes for the X, Y, and 17 chromosomes. MAIN OUTCOME MEASURE(S) Chromosomal disomy and diploidy frequencies. RESULT(S) In the HA-bound sperm (495-2,079 per man, 41,670 in all) compared with unselected sperm (4,770 per man, 162,210 in all), the chromosomal disomy frequencies were reduced to 0.16% from 0.52%, diploidy to 0.09% from 0.51%, and sex chromosome disomy to 0.05% from 0.27% (a 5.4-fold reduction vs. 4-fold respective increase in ICSI offspring). CONCLUSION(S) The HA sperm selection method for ICSI, which is based on a relationship between sperm receptors for zona pellucida and HA, will likely reduce the potential genetic complications and adverse public health effects of ICSI.
