Abstract
OBJECTIVE To investigate whether minimal ovarian stimulation (mOS) is as effective as conventional ovarian stimulation (cOS) for older women belonging to different groups according to the Poseidon criteria. MATERIAL AND METHODS Observational retrospective multicentre cohort including women from Poseidon's groups 2 and 4 that underwent in vitro fertilization (IVF). We performed a mixed-effects logistic regression model, adding as a random effect the patients and the stimulation cycle considering the dependence of data. Survival curves were employed as a measure of the cumulative live birth rate (CLBR). The primary outcomes were live birth rate per embryo transfer and CLBR per consecutive embryo transfer and oocyte consumed until a live birth was achieved. RESULTS A total of 2002 patients underwent 3056 embryo transfers (mOS = 497 and cOS = 2559). The live birth rates per embryo transfer in mOS and cOS showed no significant difference in both Poseidon's groups. Likewise, the logistic regression showed similar live birth rates between the two protocols in Poseidon's groups 2 (OR 1.165, 95% CI 0.77-1.77; p = 0.710) and 4 (OR 1.264 95% CI 0.59-2.70; p = 0.387). However, the survival curves showed higher CLBR per oocyte in women that received mOS (Poseidon group 2: p < 0.001 and Poseidon group 4: p = 0.039). CONCLUSIONS Minimal ovarian stimulation is a good alternative to COS as a first-line treatment for patients belonging to Poseidon's groups 2 and 4. The number of oocytes needed to achieve a live birth seems inferior in mOS strategy than cOS.

Abstract
Male infertility is a global health issue; yet to a large extent, our knowledge of its causes, impact and consequence is largely unknown. Recent data indicate that infertile men have an increased risk of somatic disorders such as cancer and die younger compared to fertile men. Moreover, several studies point to a significant adverse effect on the health of the offspring. From the startling lack of progress in male contraception combined with the paucity of improvements in the diagnosis of male infertility, we conclude there is a crisis in male reproductive health. The Male Reproductive Health Initiative has been organized to directly address these issues (www.eshre.eu/Specialty-groups/Special-Interest-Groups/Andrology/MRHI). The Working Group will formulate an evidence-based strategic road map outlining the ways forward. This is an open consortium desiring to engage with all stakeholders and governments.

Abstract
RESEARCH QUESTION Do donor spermatozoa improve IVF outcomes after first oocyte donation failure? DESIGN Retrospective, multicentre study including couples undergoing oocyte donation cycles using autologous or donor spermatozoa after a failed first attempt. Male partners were further characterized as normozoospermic or oligoasthenoteratospermic, i.e. fewer than 5 million motile progressive spermatozoa in the ejaculate. The main outcomes measured were live birth rate (LBR) per embryo transfer, LBR per number of embryos transferred, and cumulative LBR (CLBR) considering oocytes consumed in the previous donation cycles. RESULTS Analysis comprised 6065 cycles of oocyte donation failure; among these, subgroup analyses by sperm quality comprised 4113 cycles with severe male factor and 1150 cycles with suboptimal/normal spermatozoa. Sperm replacement in the first cycle after failure increased LBR per embryo transfer (OR 2.21, 95% CI 1.7-2.8, P < 0.001) and per number of embryos transferred (OR 2.46, 95% CI 1.9-3.1, P < 0.001) for normospermic and oligoasthenoteratospermic men. Replacement by the third cycle after failure was less beneficial (LBR per embryo transfer: OR 1.35, 95% CI 0.9-2.1, P = 0.16; LBR per embryos transferred: OR 1.33, 95% CI 0.9-2.0, P = 0.186). Kaplan-Meier curves of CLBR per oocyte fertilized with autologous or donor spermatozoa were statistically different (P < 0.001) and demonstrate how each additional oocyte may affect success based on sperm source (donor/autologous). CONCLUSIONS Donor spermatozoa improved outcomes when used after an initial failed oocyte donation cycle. The CLBR curves can be used to determine the cumulative chances of live birth using either autologous or donor spermatozoa, providing guidance on when to replace spermatozoa.

Abstract
BACKGROUND Autism spectrum disorder (ASD) has increased over tenfold over the past several decades and appears predominantly associated with paternal transmission. Although genetics is anticipated to be a component of ASD etiology, environmental epigenetics is now also thought to be an important factor. Epigenetic alterations, such as DNA methylation, have been correlated with ASD. The current study was designed to identify a DNA methylation signature in sperm as a potential biomarker to identify paternal offspring autism susceptibility. METHODS AND RESULTS Sperm samples were obtained from fathers that have children with or without autism, and the sperm then assessed for alterations in DNA methylation. A genome-wide analysis (> 90%) for differential DNA methylation regions (DMRs) was used to identify DMRs in the sperm of fathers (n = 13) with autistic children in comparison with those (n = 13) without ASD children. The 805 DMR genomic features such as chromosomal location, CpG density and length of the DMRs were characterized. Genes associated with the DMRs were identified and found to be linked to previously known ASD genes, as well as other neurobiology-related genes. The potential sperm DMR biomarkers/diagnostic was validated with blinded test sets (n = 8-10) of individuals with an approximately 90% accuracy. CONCLUSIONS Observations demonstrate a highly significant set of 805 DMRs in sperm that can potentially act as a biomarker for paternal offspring autism susceptibility. Ancestral or early-life paternal exposures that alter germline epigenetics are anticipated to be a molecular component of ASD etiology.

Abstract
Infertility is a growing concern in developed societies. Two extreme phenotypes of male infertility are non-obstructive azoospermia (NOA) and severe oligospermia (SO), which are characterized by severe spermatogenic failure (SpF). We designed a genetic association study comprising 725 Iberian infertile men as a consequence of SpF and 1058 unaffected controls to evaluate whether five single-nucleotide polymorphisms (SNPs), previously associated with reduced fertility in Hutterites, are also involved in the genetic susceptibility to idiopathic SpF and specific clinical entities. A significant difference in the allele frequencies of USP8-rs7174015 was observed under the recessive model between the NOA group and both the control group (p = 0.0226, OR = 1.33) and the SO group (p = 0.0048, OR = 1.78). Other genetic associations for EPSTI1-rs12870438 and PSAT1-rs7867029 with SO and between TUSC1-rs10966811 and testicular sperm extraction (TESE) success in the context of NOA were observed. In silico analysis of functional annotations demonstrated cis-eQTL effects of such SNPs likely due to the modification of binding motif sites for relevant transcription factors of the spermatogenic process. The findings reported here shed light on the molecular mechanisms leading to severe phenotypes of idiopathic male infertility, and may help to better understand the contribution of the common genetic variation to the development of these conditions.

Abstract
OBJECTIVE To study the pregnancy, miscarriages, and live birth rates (LBRs) according to maternal killer cell immunoglobulin-like receptor (KIR) genes expressed by uterine natural killer cells and paternal or oocyte donor human leukocyte antigen-C (HLA-C) genes expressed by trophoblast cells in patients with recurrent reproductive failure. DESIGN Prospective observational cohort study. SETTING Private infertility center. PATIENT(S) Participants included 204 women with recurrent miscarriage or recurrent implantation failure. INTERVENTION(S) The KIR and HLA-C genotypes of all women and HLA-C of their partners, gamete donors, miscarriage tissue, and babies were analyzed. MAIN OUTCOME MEASURE(S) All clinical variables (pregnancy, miscarriage, and LBRs) were analyzed and categorized based on KIR, oocyte origin, and single embryo transfer (SET)/double embryo transfer (DET). RESULT(S) A higher miscarriage rate was observed after DETs in KIR AA mothers (47.8% egg donation and 37.5% in vitro fertilization [IVF]) compared with KIR AB (10.5% egg donation and 12.5% IVF) or KIR BB (6.7% egg donation and 0% IVF). A significantly decreased LBR was observed after DETs with oocyte donation in KIR AA patients (4.3%) compared with KIR AB (26.3%) or BB (46.7%). The LBR decreased significantly as the fetal HLA-C2 load increased in KIR AA women. CONCLUSION(S) Elective SET improves the reproductive outcomes compared with DET. An increased embryo HLA-C2 load has a negative impact on the LBR in KIR AA patients. The selection of HLA-C1 over HLA-C2 donors could have a positive impact on the LBR in KIR AA patients.

Abstract
OBJECTIVE To evaluate whether SOHLH2 intronic variation contributes to the genetic predisposition to male infertility traits, including severe oligospermia (SO) and different nonobstructive azoospermia (NOA) clinical phenotypes. DESIGN Genetic association study. SETTING Not applicable. PATIENT(S) Five hundred five cases (455 infertile patients diagnosed with NOA and 50 with SO) and 1,050 healthy controls from Spain and Portugal. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Genomic DNA extraction from peripheral blood mononuclear cells, genotyping of the SOHLH2 polymorphisms rs1328626 and rs6563386 using the TaqMan allelic discrimination technology, case-control association analyses using logistic regression models, and exploration of functional annotations in publicly available databases. RESULT(S) Evidence of association was observed for both rs6563386 with SO and rs1328626 with unsuccessful sperm retrieval after testicular sperm extraction (TESE-) in the context of NOA. A dominant effect of the minor alleles was suggested in both associations, either when the subset of patients with the manifestation were compared against the control group (rs6563386/SO: P=.021, odds ratio [OR] = 0.51; rs1328626/TESE-: P=.066, OR = 1.46) or against the group of patients without the manifestation (rs6563386/SO: P=.014, OR = 0.46; rs1328626/TESE-: P=.012, OR = 2.43). The haplotype tests suggested a combined effect of both polymorphisms. In silico analyses evidenced that this effect could be due to alteration of the isoform population. CONCLUSION(S) Our data suggest that intronic variation of SOHLH2 is associated with spermatogenic failure. The genetic effect is likely caused by different haplotypes of rs6563386 and rs1328626, which may predispose to SO or TESE- depending on the specific allelic combination.

Abstract
The prolonged lockdown of health facilities providing non‐urgent gamete cryopreservation—as currently recommended by many reproductive medicine entities and regulatory authorities due to the SARS‐CoV‐2 pandemic will be detrimental for subgroups of male infertility patients. We believe the existing recommendations should be promptly modified and propose that the same permissive approach for sperm banking granted for men with cancer is expanded to other groups of vulnerable patients. These groups include infertility patients (eg, azoospermic and cryptozoospermic) undergoing medical or surgical treatment to improve sperm quantity and quality, as well as males of reproductive age affected by inflammatory and systemic auto‐immune diseases who are about to start treatment with gonadotoxic drugs or who are under remission. In both scenarios, the “fertility window” may be transitory; postponing diagnostic semen analysis and sperm banking in these men could compromise the prospects of biological parenthood. Moreover, we provide recommendations on how to continue the provision of andrological services in a considered manner and a safe environment. Our opinion is timely and relevant given the fact that fertility services are currently rated as of low priority in most countries.

Abstract
Personalized medicine gathers the most relevant data involved in human health. Currently, the diagnosis of male infertility is limited to spermiogram, which does not provide information on the male fertile potential. New diagnostic methods are required. The application of omics techniques in the study of male reproductive health renders a huge amount of data providing numerous novel infertility biomarkers, from genes to metabolites, to diagnose the cause of male infertility. Recent studies hold the promise that these biomarkers will allow a noninvasive infertility diagnosis and the improvement of the sperm selection techniques.

Abstract
Excessive levels of reactive nitrogen species (RNS) produce nitrosative stress. Among RNS is peroxynitrite, a highly reactive free radical generated when nitric oxide reacts with superoxide anion. Peroxynitrite effects have been mainly studied in somatic cells, and in spermatozoa the majority of studies are focused in humans. The aim of this study is to investigate the in vitro peroxynitrite effect on boar spermatozoa functions and the molecular mechanisms involved. Spermatozoa were exposed to the donor 3-morpholinosydnonimine (SIN-1) in non-capacitating or capacitating medium, motility was evaluated by CASA, functional parameters by flow cytometry and sperm protein phosphorylation by Western blotting. SIN-1 treatment, that significantly increases peroxynitrite levels in boar spermatozoa, potentiates the capacitating-stimulated phosphorylation of cAMP-dependent protein kinase 1 (PKA) substrates and GSK-3α. SIN-1 induced peroxynitrite does not decrease sperm viability, but significantly reduces sperm motility, progressive motility, velocities and motility coefficients. Concomitantly, peroxynitrite does not affect mitochondrial membrane potential, plasma membrane fluidity, or A23187-induced acrosome reaction. However, peroxynitrite significantly increases sperm lipid peroxidation in both media. In conclusion, peroxynitrite compromises boar sperm motility without affecting mitochondrial activity. Although peroxynitrite potentiates the phosphorylation of pathways leading to sperm motility, it also causes oxidative stress that might explain, at least partially, the motility impairment.

Abstract
Abstract
STUDY QUESTION
What is the risk of developing intracavitary fluid (ICF) during ovarian stimulation in patients with an isthmocele after previous caesarean section (CS) delivery?
SUMMARY ANSWER
In patients with an existing isthmocele, the risk of developing ICF during hormonal stimulation for IVF is almost 40%; therefore, special attention has to be paid to exclude fluid accumulation during stimulation and particularly at the time of transfer, in which case the reproductive outcomes of frozen embryo transfer (FET) cycles appear to be uncompromised.
WHAT IS KNOWN ALREADY
Lately, there is an increasing focus on the long-term impact of CS delivery on the health and future fertility of the mother. Development of an isthmocele is one of the sequelae of a CS delivery. The presence of ICF in combination with an isthmocele has been described previously, and the adverse effect of endometrial fluid on implantation is well recognised by reproductive medicine specialists. Accumulation of ICF has been previously described in patients with hydrosalpinx, less commonly in patients with polycystic ovary syndrome undergoing ovarian stimulation for IVF/ICSI, and even in some patients without any identifiable reason. Assisted reproductive techniques (ARTs) are a means to overcome infertility. Reproductive medicine specialists commonly see patients with secondary infertility with a history of having had one or more previous CS and with ultrasound confirmation of an isthmocele. However, the available data pertaining to the prevalence of intracavitary fluid during ovarian stimulation in patients with ultrasound confirmation of an isthmocele is limited. Furthermore, data on the influence of ICF in a stimulated cycle on the ART outcome of a subsequent FET cycle is scarce and merits further studies.
STUDY DESIGN, SIZE, DURATION
A prospective observational exploratory study was performed in IVI Middle East Fertility Clinic, Abu Dhabi, from June 2018 to March 2019, and retrospective analysis of the reproductive outcomes was performed until July 2019.
PARTICIPANTS/MATERIALS, SETTING, METHODS
Patients with secondary infertility, defined as a minimum of 1 year of infertility after a previous successful pregnancy, undergoing ovarian stimulation for IVF/ICSI and having a history of one or more previous CS with ultrasonographic visible isthmocele, were included (n = 103). Patients were monitored as a clinical routine with vaginal ultrasound examinations during ovarian stimulation for IVF/ICSI treatment. All patients included in the study were asked to complete a questionnaire regarding their previous obstetric history. Development of ICF was recorded as well as changes in the measurements of the isthmocele during the course of ovarian stimulation. Reproductive outcomes of FET cycles of the patients with an isthmocele were retrospectively compared to those of patients with infertility and without isthmocele in our clinic during the same time period.
MAIN RESULTS AND THE ROLE OF CHANCE
Patients with an existing isthmocele after previous CS have a risk of ~40% of developing ultrasonographic visible fluid in the endometrial cavity during the course of ovarian stimulation. Development of ICF was significantly correlated with the depth of the isthmocele on Day 2/3 (P = 0.038) and on the day of trigger (−1/−2 days) (P = 0.049), circumference of the isthmocele on the day of trigger (−1/−2 days) (P = 0.040), distance from the C-scar to the external os (P = 0.036), number of children delivered (P = 0.047) and number of previous CS (P = 0.035). There was a statistically significant increase in the parameters related to the size of the isthmocele during ovarian stimulation. No significant differences in the reproductive outcome (pregnancy rate and rates of biochemical and ectopic pregnancies, miscarriages and ongoing/delivered pregnancies) after FET were found between the patients with and without an isthmocele, when ICF was excluded prior to embryo transfer procedure.
LARGE-SCALE DATA
NA.
LIMITATIONS, REASONS FOR CAUTION
This study was not primarily designed to investigate the causes of ICF during ovarian stimulation or to evaluate the reproductive outcomes. Further, the small number of reported reproductive outcomes may be seen as a limitation.
WIDER IMPLICATIONS OF THE FINDINGS
The data highlights the need for an increased awareness on the part of reproductive medicine specialists towards the potentially adverse impact of an isthmocele on ART treatment, as there is a potential to develop intracavitary fluid during ovarian stimulation for IVF. The increase in the circumference of the isthmocele may increase embryo transfer difficulty.
STUDY FUNDING/COMPETING INTEREST(S)
No funding of the study has to be reported. The authors have no competing interests.

Abstract
Angiotensin-converting enzyme functions in the male reproductive system, but the extent of its function in reproduction is not fully understood. The primary objective of this work was to investigate the relationship between the testicular isoform of angiotensin-converting enzyme present in human spermatozoa and semen parameters, human embryo quality, and assisted reproduction success. A total of 81 semen samples and 635 embryos from couples undergoing oocyte donation cycles at the IVI Bilbao Clinic were analyzed. Semen parameters, embryos quality, and blastocyst development were examined according to the World Health Organization standards and the Spanish Association of Reproduction Biology Studies criteria. The percentage of testicular angiotensin-converting enzyme-positive spermatozoa and the number of molecules per spermatozoon were analyzed by flow cytometry. Both parameters were inversely correlated with human sperm motility. Higher percentages of testicular angiotensin-converting enzyme-positive spermatozoa together with fewer enzyme molecules per spermatozoon were positively correlated with better embryo quality and development. Our results suggest that embryos with a higher implantation potential come from semen samples with higher percentages of testicular angiotensin-converting enzyme-positive cells and fewer enzyme molecules per spermatozoon. Based on these findings, we propose that testicular angiotensin-converting enzyme could be used to aid embryologists in selecting better semen samples for obtaining high-quality blastocysts during in vitro fertilization procedures.

Abstract
RESEARCH QUESTION Does ovarian stimulation for oocyte vitrification affect disease-free survival and overall survival rates in women with early breast cancer? DESIGN This cohort study included 259 patients with early breast cancer; 148 patients underwent ovarian stimulation, whereas 111 patients did not. Patients were treated between January 2008 and December 2016. To calculate the disease-free survival time and overall survival rate, the time of definitive surgery was defined as the starting point. The follow-up was conducted up to 5 years. RESULTS Exposed and non-exposed groups were comparable in tumour, node and metastases classification, Nottingham grade, hormonal receptor status, tumour molecular phenotype, histology and pathology stage. The exposed group was younger than the non-exposed. Recurrences occurred in 9/148 women (6.1%) in the exposed group and 15/111 women (13.5%) in the non-exposed group, with no significant difference. The mean disease-free survival time was 63.9 months (95% confidence interval [CI]: 61.5-66.4) in the exposed group and 60.6 months (95% CI: 56.9-64.2) in the non-exposed, with no significant difference (log-rank [Mantel-Cox] test). Overall survival rates were comparable; 2/148 (1.4%) and 4/111 (3.6%) patients died, in exposed and non-exposed groups, respectively, during the period analysed. Mean overall survival times were 67.2 months (95% CI: 66.2-68.2) in the exposed group and 65.9 months (95% CI: 64.0-67.9) in the unexposed, with no significant difference (log-rank [Mantel-Cox] test). CONCLUSIONS This study suggests that ovarian stimulation in patients with early-stage breast cancer is safe in the long term.

Abstract
Spermatozoa retrieved from the testis of men with high levels of sperm DNA fragmentation (SDF) in the neat semen tend to have better DNA quality. Given the negative impact of SDF on the outcomes of Assisted Reproductive Technology (ART), an increased interest has emerged about the use of testicular sperm for intracytoplasmic sperm injection (Testi-ICSI). In this article, we used a SWOT (strengths, weaknesses, opportunities, and threats) analysis to summarize the advantages and drawbacks of this intervention. The rationale of Testi-ICSI is bypass posttesticular DNA fragmentation caused by oxidative stress during sperm transit through the epididymis. Hence, oocyte fertilization by genomically intact testicular spermatozoa may be optimized, thus increasing the chances of creating a normal embryonic genome and the likelihood of achieving a live birth, as recently demonstrated in men with high SDF. However, there is still limited evidence as regards the clinical efficacy of Testi-ICSI, thus creating opportunities for further confirmatory clinical research as well as investigation of Testi-ICSI in clinical scenarios other than high SDF. Furthermore, Testi-ICSI can be compared to other laboratory preparation methods for deselecting sperm with damaged DNA. At present, the available literature supports the use of testicular sperm when performing ICSI in infertile couples whose male partners have posttesticular SDF. Due to inherent risks of sperm retrieval, Testi-ICSI should be offered when less invasive treatments for alleviating DNA damage have failed. A call for continuous monitoring is nonetheless required concerning the health of generated offspring and the potential complications of sperm retrieval.

Abstract
STUDY QUESTION Is endometrial recurrent implantation failure (RIF) only a matter of an asynchronous (displaced) window of implantation (WOI), or could it also be a pathological (disrupted) WOI? SUMMARY ANSWER Our predictive results demonstrate that both displaced and disrupted WOIs exist and can present independently or together in the same RIF patient. WHAT IS KNOWN ALREADY Since 2002, many gene expression signatures associated with endometrial receptivity and RIF have been described. Endometrial transcriptomics prediction has been applied to the human WOI in two previous studies. One study describes endometrial RIF to be the result of a temporal displacement of the WOI. The other indicates that endometrial RIF can also result from a molecularly disrupted WOI without temporal displacement. STUDY DESIGN, SIZE, DURATION Retrospective analysis was undertaken to compare WOI endometrial transcriptomics predictions in controls (n = 72) and RIF patients (n = 43). RIF was clinically designated by the absence of implantation after four or more transfers of high quality embryos or after the placement of 10 or more embryos in multiple transfers. Endometrial tissue samples were collected from LH + 5 to LH + 8. We compared the two molecular causes of RIF to signatures currently described in the literature. We propose a new transcriptomic RIF taxonomy to fill the gap between the two hypotheses and to guide the development of clinical detection and determination of both types of RIF. PARTICIPANTS/MATERIALS, SETTING, METHODS Utilizing 115 gene expression profiles, two different predictive designs were developed: one considering RIF versus controls removing menstrual cycle timing, called the disrupted or pathological model, and another stratifying the WOI in transcriptomic profiles related to timing for predicting displacements. The predictive value of each model was compared between all signatures selected. We propose a new genomic approach that distinguishes between both types of RIF in the same sample cohort. MAIN RESULTS AND THE ROLE OF CHANCE From the 16 signatures analysed, we clearly predicted two causes of RIF-both a displaced WOI and an on-time but pathologically disrupted WOI. A high predictive value related to WOI profiles associated with menstrual cycle timing was found in most of the signatures. Specifically, 69% of the signatures analysed presented an accuracy higher than expected by chance in a range from 0.87 to 0.97. Displacements and disruptions were not molecularly independent, as some signatures were moderately associated with both causes. The gene and functional comparison between signatures revealed that they were not similar, although we did find functions in common and a cluster of moderate functional concordance between some of the signatures that predicted displacements (the highest Cohen's Kappa index were between 0.55 and 0.62 depending on the functional database). We propose a new transcriptomic RIF taxonomy to fill the gap between these prior studies and to establish methodology for detecting and distinguishing both types of RIF in clinical practice. Our findings indicate these two phenotypes could present independently or together in the same RIF patient. RIF patients designated by clinical criteria have been stratified transcriptomically as 18.6% with only a displaced WOI, 53.5% with a displaced and pathological WOI, 23.3% with only a disrupted WOI, and 4.7% could be a clinical RIF with non-endometrial origin. The new RIF transcriptomic taxonomy avoids menstrual cycle timing as a confounding variable that should be controlled for, distinguishing clearly between a disrupted and a displaced WOI for precision medicine in RIF. LIMITATIONS REASONS FOR CAUTION The main objective of this study was to use transcriptomics to detect both RIF causes and to understand the role of transcriptomic signatures in these phenotypes. The predictive value in absolute terms for each signature was not indicative in these prediction designs; instead, the comparison between signatures was most important for prediction capability in the same sample cohort for both RIF causes. Clinical follow up of the RIF taxonomies proposed has not been analysed in this study, so further prospective clinical studies are necessary to determine the prevalence and penetrance of these phenotypes. WIDER IMPLICATIONS OF THE FINDINGS The main insight from this study is a new understanding of RIF taxonomy. Understanding how to classify RIF patients to distinguish clinically between a patient who could benefit from a personalized embryo transfer day and a patient with a disrupted WOI will enable identification and stratification for the research and development of new treatments. In addition, we demonstrate that basic research designs in endometrial transcriptomics cause masking of the study variable by the menstrual cycle timing. STUDY FUNDING/COMPETING INTEREST(S) This research has been funded by IVI-RMA; the authors do not have any competing interests.

Abstract
Caracteres de la canal y calidad de carne de tres genotipos distintos de ibérico puro, Retinto (R), Torbiscal (T) y Torbiscal*Retinto (TR), y un cruce de Duroc*Retinto (DR) han sido estudiados. Se han utilizado 48 cerdos, 12 por genotipo. El espesor de los diferentes depósitos de la grasa dorsal: interno (i), medio (m), externo (o) y total (t), medidos a nivel de la décima y decimo cuarta costilla (iBF10, mBF10, oBF10, tBF10, iBF14, mBF14, oBF14 y tBF14, respectivamente) se midieron en la canal así como el área del lomo (LA10 y LA14, respectivamente) y el porcentaje de grasa intramuscular (IMF) se determinó químicamente. Los pesos (W) y rendimientos (Y) de las piezas más importantes: jamón (H), paleta (F), lomo (L), y solomillo (TL) se recogieron (HW, FW, LW, TLW y HY, FY y LY, respectivamente). Los pesos y rendimientos de todas las piezas se calculó también (TCW y TCY). Como el genotipo DR creció más rápido de lo esperado, estos animales se finalizaron con un concentrado y no con bellota como los otros tres genotipos. Así, el genotipo DR solo se compara para caracteres de canal. Los datos se analizaron utilizando el procedimiento GLM de SAS, ajustando por el peso de canal dentro de cada genotipo como covariable. Como resultados el genotipo R tuvo valores de IMF, IBF10, MBF10 y TBF10, significativamente mayores que los otros genotipos y el genotipo T tuvo valores significativamente mayores que los otros genotipos para OBF10 y OBF14. Además, HW y HY obtuvieron valores semejantes para todos los genotipos, pero TR y DT obtuvieron paletas y lomos más pesados que los genotipos R y T. Dentro de los genotipos ibéricos puros TR obtuvo mejores TCW y TCY que R pero igual que T. Por otro lado, el genotipo DR fue el que obtuvo los mejores valores para TCW y TCY.

Abstract
El fin voluntario de la castración de machos porcinos se prevé próximamente en la UE. Pero los protocolos habituales de inmunocastración (IC) necesitan ser modificados para los machos Ibéricos (IB) debido a su largo ciclo vital. Nuestro grupo desarrolló un protocolo de 3 dosis que pretendemos ajustar a la cronología de la montanera, basándonos en la hipótesis de que la uniformidad de la condición corporal al inicio de la montanera intensificará y homogeneizará la atrofia testicular. Machos IB puros (n=35) fueron alimentados de forma restringida durante la pre-montanera como es habitual. De ellos, los machos Control (C; n=18) fueron inmunizados contra la GnRH a los 10,5, 12 y 13,5 meses (m) de edad, y los Tratados (T; n=17) a los 10,5, 11,5 y 13 m, alimentándose estos últimos ad libitum (AL) durante 15 días desde la 3ª dosis. Ambos grupos comenzaron la montanera a los 13,5 m, coincidiendo con la 3ª dosis de C y el fin del periodo AL de T, sacrificándose ambos a los 16 m. Para corroborar el efecto del nivel nutricional, otro grupo fue alimentado ad libitum durante el pre-cebo y cebo en sistema extensivo regular (Adlib; n=15 machos IB x Duroc), inmunizándose a los 8, 9 y 11 m y sacrificándose a los 13 m (más temprano, debido al genotipo y alimentación). Los testículos y epidídimos fueron significativamente menores en los machos Adlib y T que en los C. Similarmente, las glándulas bulbouretrales fueron significativamente menores en los machos T que en los C. El color “a” (de verde a rojo) del parénquima testicular estuvo altamente correlacionado (r=0,87) con el peso testicular. La grasa dorsal resultó negativa a androstenona y escatol en todos los animales. Los rendimientos de paletas, lomos y piezas de primera fueron significativamente mayores en los machos Adlib que en los C y T. En conclusión, el nivel nutricional puede ser utilizado para mejorar la eficacia de la IC de machos, y la colorimetría testicular puede ser útil para evaluar dicha eficacia.

Abstract
One hundred thirty-six isolates, 88 human and 48 environmental, that met the requirements to belong to the genus Paenibacillus were identified using a polyphasic taxonomic approach known as 16S rRNA plus phenotypic traits. Thirty-seven Paenibacillus species were identified; some had not been previously reported from clinical samples. The main species were P. pabuli (13 isolates), P. provencensis (11), P. phoenicis (9) and P. lautus (8). P. pabuli (11/13) and P. provencensis (8/11) were mainly environmental isolates, while P. phoenicis (9/9) and P. lautus (6/8) were mainly human isolates. Despite the difficulties in assigning to human Paenibacillus isolates a role as a pathogen or contaminant, here 25% of the isolates were involved in true infections, especially in those cases that affected abscesses, wound exudates, ocular infections and diverse fluids. In addition, 15 isolates were identified as 11 'Candidatus' to a new species, all of them from human specimens except one that was obtained from laboratory air. The antimicrobial susceptibility testing showed 95.6% of isolates were resistant to ampicillin, 44% were resistant to cotrimoxazole, 20 to 30% were resistant to cefotaxime and vancomycin and 13% were resistant to rifampicin and erythromycin.

Abstract
Deciphering the underlying causes of idiopathic male infertility is one of the main challenges in reproductive medicine. This is especially relevant in infertile patients displaying normal seminal parameters and no urogenital or genetic abnormalities. In these cases, the search for additional sperm biomarkers is of high interest. This study was aimed to determine the implications of the sperm miRNA expression profiles in the reproductive capacity of normozoospermic infertile individuals. The expression level of 736 miRNAs was evaluated in spermatozoa from eight normozoospermic infertile males using TaqMan® qRT-PCR. Results were contrasted with data from 10 control normozoospermic fertile individuals analyzed under the same conditions. Clustering analysis of miRNA expression data separated the individuals according to their fertility condition (fertile and infertile). Fifty-seven miRNAs were differentially expressed (DE-miRNAs) between populations; 20 of them was regulated by a host gene promoter that in three cases comprised genes involved in fertility. The predicted targets of the DE-miRNAs (n = 8,606) unveiled a significant enrichment of biological processes related to embryonic morphogenesis and chromatin modification. Normozoospermic infertile individuals exhibit a specific sperm miRNA expression profile clearly differentiated from normozoospermic fertile individuals. This miRNA cargo has potential implications in the individuals' reproductive competence.

Abstract
![]()
The current catalogue of the human
proteome is not yet complete,
as experimental proteomics evidence is still elusive for a group of
proteins known as the missing proteins. The Human Proteome Project
(HPP) has been successfully using technology and bioinformatic resources
to improve the characterization of such challenging proteins. In this
manuscript, we propose a pipeline starting with the mining of the
PRIDE database to select a group of data sets potentially enriched
in missing proteins that are subsequently analyzed for protein identification
with a method based on the statistical analysis of proteotypic peptides.
Spermatozoa and the HEK293 cell line were found to be a promising
source of missing proteins and clearly merit further attention in
future studies. After the analysis of the selected samples, we found
342 PSMs, suggesting the presence of 97 missing proteins in human
spermatozoa or the HEK293 cell line, while only 36 missing proteins
were potentially detected in the retina, frontal cortex, aorta thoracica,
or placenta. The functional analysis of the missing proteins detected
confirmed their tissue specificity, and the validation of a selected
set of peptides using targeted proteomics (SRM/MRM assays) further
supports the utility of the proposed pipeline. As illustrative examples,
DNAH3 and TEPP in spermatozoa, and UNCX and ATAD3C in HEK293 cells
were some of the more robust and remarkable identifications in this
study. We provide evidence indicating the relevance to carefully analyze
the ever-increasing MS/MS data available from PRIDE and other repositories
as sources for missing proteins detection in specific biological matrices
as revealed for HEK293 cells.

Abstract
OBJECTIVE To assess outcomes after oocyte vitrification on obstetric and perinatal outcomes compared with those achieved with fresh oocytes. DESIGN Retrospective cohort study. SETTING Private university-affiliated IVF center. PATIENT(S) Children born after use of vitrified oocytes (1,027 from 804 pregnancies) and fresh oocytes (1,224 from 996 pregnancies). Singleton and multiples pregnancies from own and donated ova were included. INTERVENTION(S) Oocyte vitrification by the Cryotop method. MAIN OUTCOME MEASURE(S) Pregnancy, delivery, and neonatal outcomes. RESULT(S) Vitrification had no clinically relevant adverse effects on obstetric and perinatal outcomes after adjusting for potential confounders. No differences were found between the vitrified and fresh oocyte groups in the rate of obstetric problems (including diabetes, pregnancy-induced hypertension, preterm birth, anemia, and cholestasis), gestational age at delivery, birth weight, Apgar scores, birth defects, admission to neonatal intensive care unit (ICU), perinatal mortality, and puerperal problems. Only a greater number of invasive procedures (adjusted odds ratio 2.12; 95% confidence interval 1.41-3.20), and a reduced occurrence of urinary tract infection (adjusted odds ratio 0.51; 95% confidence interval 0.28-0.91), were observed in the vitrified oocytes group. CONCLUSION(S) Although our data, the largest series to date, suggest that oocyte vitrification does not increase adverse obstetric and perinatal outcomes in children conceived with vitrified oocytes, further studies with larger samples are required to reinforce our conclusions.

Abstract
OBJECTIVE To characterize the microRNA (miRNA) expression profile in spermatozoa from human fertile individuals and their implications in human fertility. DESIGN The expression levels of 736 miRNAs were evaluated using TaqMan arrays. Ontologic analyses were performed to determine the presence of enriched biological processes among their targets. SETTING University research and clinical institutes. PATIENT(S) Ten individuals with normal seminogram, standard karyotype, and proven fertility. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Expression levels of 736 miRNAs, presence of enriched metabolic routes among their targets, homogeneity of the population, influence of demographic features in the results, presence of miRNA stable pairs, and best miRNA normalizing candidates. RESULT(S) A total of 221 miRNAs were consistently present in all individuals, 452 were only detected in some individuals, and 63 did not appear in any sample. The ontologic analysis of the 2,356 potential targets of the ubiquitous miRNAs showed an enrichment of processes related to cell differentiation, development, morphogenesis, and embryogenesis. None of the miRNAs were significantly correlated with age, semen volume, sperm concentration, motility, or morphology. Correlations between samples were statistically significant, indicating a high homogeneity of the population. A set of 48 miRNA pairs displayed a stable expression, a particular behavior that is discussed in relationship to their usefulness as fertility biomarkers. Hsa-miR-532-5p, hsa-miR-374b-5p, and hsa-miR-564 seemed to be the best normalizing miRNA candidates. CONCLUSION(S) Human sperm contain a stable population of miRNAs potentially related to embryogenesis and spermatogenesis.

Abstract
PURPOSE To find out whether the MTHFR rs1801133 polymorphism is a risk factor for male infertility in the Spanish population. To determine if a pattern of sperm DNA hypomethylation at the paternally imprinted loci H19-ICR and/or IG-DMR is related to the MTHFR rs1801133 polymorphism and/or CTCFL mutations. METHODS One hundred and seven samples from individuals who sought consultation for fertility problems and twenty-five semen samples from sperm donors were analyzed. The MTHFR rs1801133 SNP was analyzed in all samples by the PCR-RFLP method. We compared the distribution of the genotypes between control and infertile populations and among the groups of patients with altered seminal parameters. In those patients with the most severe hypomethylation pattern (n = 12) we also analyzed the CTCFL protein-coding exons by sequencing. RESULTS There were no significant differences in the distribution of the genotypes among the control and infertile populations. Moreover, none of the genotypes were associated, neither to the characteristics of the seminogram, nor to the presence of sperm DNA hypomethylation. We did not identify frameshift, nonsense or missense mutations of the CTCFL gene. CONCLUSIONS The MTHFR rs1801133 polymorphism is not associated with male infertility in the Spanish population. Neither the MTHFR polymorphism, nor CTCFL mutations explain a pattern of sperm hypomethylation at paternally imprinting loci.
