Abstract
Assisted reproductive technologies (ART) increasingly occupy the study of human reproduction. In addition, in developed countries they contribute to breeding of more than 50 % of cattle. In the management of collections of genetic lines of laboratory animals, these technologies are obligatory components of cryopreservation and rederivation. ART procedures include the development of early embryos outside the mother's body and the high probability of incomplete synchronization of the physiological state of the surrogate mother and transplanted embryos. Since all this occurs at the stage of the highest susceptibility of embryos to epigenetic reprogramming, the full cycle of ART and its individual components can lead to stable phenotypic changes in the offspring. Their reality is confirmed by studies of the morphological and functional characteristics of sexually mature offspring of CD1 outbred mice, obtained using different variants of early embryo transplantation. Comparative studies of body mass and body composition, basal glucose level and response to glucose load (glucose-tolerance test - GTT) have been done on sexually mature males and females. Animals were separated in 4 groups according to the variant of embryo transplantation: group (control) - natural mating; group (2cl-bl) - incubation of 2-cell up to blastocysts; group (2cl-2cl) - removal and transplantation of the 2-cell embryo without incubation; group (Bl-bl) removal and transplantation of the blastocysts without incubation. All embryos were transplanted to recipient females of the same line. It was found that sexually mature offspring obtained with all variants of transplantations had a higher relative fat content and, correspondingly, lower lean mass compared to the control. This effect was more pronounced in females than in males. Unlike body compositions, embryo transplantations had a greater effect on basal glucose concentration and GTT in males than in females. In this case, the offspring of the 2cl-2cl and 2cl-bl groups were characterized by a higher tolerance to glucose load (GTT) compared with the control and the Bl-bl group. Stable deviations of body compositions and glucose homeostasis indices detected in experimental groups of progenies indicate the phenotypic significance of the embryo transplantations per se.

Abstract
Embryo transfer (ET) is an important procedure for assisted reproduction. However, the relatively lower success rate of ET hampers its application potential. In this study we aimed to elucidate the effects of extracellular vesicles derived from donor oviduct fluid (EDOF) on embryo development after ET. Extracellular vesicles from the oviduct were isolated and purified using ultracentrifugation and identified using transmission electron microscopy, NanoSight, bicinchoninic acid (BCA) protein assay and western blotting. The results revealed that extracellular vesicles were present in donor oviduct fluid in higher concentrations (P<0.05) and contained more proteins (P<0.05) than extracellular vesicles derived from recipient oviduct fluid (EROF). EDOF or EROF were supplemented in an ET medium (ETM) and the results showed that EDOF significantly improved birth rate via resisting apoptosis and promoting differentiation. In conclusion, our study indicated that there are differences in EDOF and EROF and that supplementing EDOF to ETM can improve the efficiency of ET; improved ET efficiency promotes the use of gene editing and benefits assisted reproductive technology and animal welfare.

Abstract
During murine embryo transfer, air bubbles frequently are loaded with embryos into the transfer catheter, but the role of air bubbles on embryonic development is unclear. This study shows that intrauterine air disrupted embryo spacing, induced deciduoma, and impaired postimplantation development. RNA sequencing showed that the gene expression profile of air-induced deciduoma differed significantly from that of embryo-induced decidua but is similar to tetraploid-induced deciduoma. A subset of 33 common genes was upregulated in the embryo-induced decidua compared with air- or tetraploid-induced deciduoma. These data suggest that the inner cell mass (ICM) plays a key role in regulating decidualization and that the trophectoderm is an intermediate that relays ICM-derived signals to other target cells. Our results may provide an innovative approach for detecting the developmental status of embryos in human reproductive medicine.

Abstract
Besides its fibrinolytic function, the plasminogen–plasmin (PLG–PLA) system is also involved in fertilisation, where plasminogen activators bind to plasminogen to produce plasmin, which modulates sperm binding to the zona pellucida. However, controversy exists, depending on the species, concerning the role of the different components of the system. This study focused its attention on the role of the PLG–PLA system on fertilisation in the mouse with special attention to tissue plasminogen activator (tPA). The presence of exogenous plasminogen reduced invitro fertilisation (IVF) rates and this decline was attenuated by the presence of plasmin inhibitors in combination with plasminogen. The incubation of spermatozoa with either oocytes or cumulus cells together with plasminogen did not change the acrosome reaction but reduced the number of spermatozoa attached. When spermatozoa from tPA−/− mice were used, the IVF rate decreased drastically, although the addition of exogenous tPA during gamete co-incubation under invitro conditions increased fertilisation success. Moreover, fertility could not be restored after invivo insemination of tPA−/− spermatozoa in the female ampulla, although tPA−/− males were able to fertilise invivo. This study suggests a regulatory role of the PLG–PLA system during fertilisation in the mouse with possible implications in human reproduction clinics, such as failures in tPA production, which could be partially resolved by the addition of exogenous tPA during IVF treatment.

Abstract
The ejaculate is a heterogeneous pool of spermatozoa containing only a small physiologically adequate subpopulation for fertilization. As there is no method to isolate this subpopulation, its specific characteristics are unknown. This is one of the main reasons why we lack effective tools to identify male infertility and for the low efficiency of assisted reproductive technologies. The aim of this study was to improve ICSI outcome by sperm selection through thermotaxis. Here we show that a specific subpopulation of mouse and human spermatozoa can be selected in vitro by thermotaxis and that this subpopulation is the one that enters the fallopian tube in mice. Further, we confirm that these selected spermatozoa in mice and humans show a much higher DNA integrity and lower chromatin compaction than unselected sperm, and in mice, they give rise to more and better embryos through intracytoplasmic sperm injection, doubling the number of successful pregnancies. Collectively, our results indicate that a high quality sperm subpopulation is selected in vitro by thermotaxis and that this subpopulation is also selected in vivo within the fallopian tube possibly by thermotaxis.

Abstract
Mouse maternal low protein diet exclusively during preimplantation development (Emb-LPD) is sufficient to programme altered growth and cardiovascular dysfunction in offspring. Here, we use an in vitro model comprising preimplantation culture in medium depleted in insulin and branched-chain amino acids (BCAA), two proposed embryo programming inductive factors from Emb-LPD studies, to examine the consequences for blastocyst organisation and, after embryo transfer (ET), postnatal disease origin. Two-cell embryos were cultured to blastocyst stage in defined KSOM medium supplemented with four combinations of insulin and BCAA concentrations. Control medium contained serum insulin and uterine luminal fluid amino acid concentrations (including BCAA) found in control mothers from the maternal diet model (N-insulin + N-bcaa). Experimental medium (three groups) contained 50% reduction in insulin and/or BCAA (L-insulin + N-bcaa, N-insulin + L-bcaa, and L-insulin + N-bcaa). Lineage-specific cell numbers of resultant blastocysts were not affected by treatment. Following ET, a combined depletion of insulin and BCAA during embryo culture induced a non sex-specific increase in birth weight and weight gain during early postnatal life. Furthermore, male offspring displayed relative hypertension and female offspring reduced heart/body weight, both characteristics of Emb-LPD offspring. Combined depletion of metabolites also resulted in a strong positive correlation between body weight and glucose metabolism that was absent in the control group. Our results support the notion that composition of preimplantation culture medium can programme development and associate with disease origin affecting postnatal growth and cardiovascular phenotypes and implicate two important nutritional mediators in the inductive mechanism. Our data also have implications for human assisted reproductive treatment (ART) practice. Chronic disease may derive from maternal undernutrition during pregnancy, including the periconceptional period. Mouse embryos cultured in medium low in insulin and select amino acids gave rise to offspring with disease symptoms. We propose these metabolite deficiencies around conception induce adverse programming of the early embryo leading to increased disease risk in later life.

Advanced maternal age causes adverse programming of mouse blastocysts leading to altered growth and impaired cardiometabolic health in post-natal life. Hum Reprod 2016; 31:1970-80.

Abstract
STUDY QUESTION Does advanced maternal age (AMA) in mice affect cardiometabolic health during post-natal life in offspring derived from an assisted reproduction technology (ART) procedure? SUMMARY ANSWER Offspring derived from blastocysts collected from aged female mice displayed impaired body weight gain, blood pressure, glucose metabolism and organ allometry during post-natal life compared with offspring derived from blastocysts from young females; since all blastocysts were transferred to normalized young mothers, this effect is independent of maternal pregnancy conditions. WHAT IS KNOWN ALREADY Although studies in mice have shown that AMA can affect body weight and behaviour of offspring derived from natural reproduction, data on the effects of AMA on offspring cardiometabolic health during post-natal development are not available. Given the increasing use of ART to alleviate infertility in women of AMA, it is pivotal to develop ART-AMA models addressing the effects of maternal aging on offspring health. STUDY DESIGN, SIZE, DURATION Blastocysts from old (34-39 weeks) or young (8-9 weeks) C57BL/6 females mated with young CBA males (13-15 weeks) were either subjected to differential cell staining (inner cell mass and trophectoderm) or underwent embryo transfer (ET) into young MF1 surrogates (8-9 weeks) to produce young (Young-ET, 9 litters) and old (Old-ET, 10 litters) embryo-derived offspring. Offspring health monitoring was carried out for 30 weeks. PARTICIPANTS/MATERIALS, SETTING, METHODS All animals were fed with standard chow. Blood pressure was measured at post-natal Weeks 9, 15 and 21, and at post-natal Week 30 a glucose tolerance test (GTT) was performed. Two days after the GTT mice were killed for organ allometry. Blastocyst cell allocation variables were evaluated by T-test and developmental data were analysed with a multilevel random effects regression model. MAIN RESULTS AND THE ROLE OF CHANCE The total number of cells in blastocysts from aged mice was decreased (P < 0.05) relative to young mice due to a lower number of cells in the trophectoderm (mean ± SEM: 34.5 ± 2.1 versus 29.6 ± 1.0). Weekly body weight did not differ in male offspring, but an increase in body weight from Week 13 onwards was observed in Old-ET females (final body weight at post-natal Week 30: 38.5 ± 0.8 versus 33.4 ± 0.8 g, P < 0.05). Blood pressure was increased in Old-ET offspring at Weeks 9-15 in males (Week 9: 108.5 ± 3.13 versus 100.8 ± 1.5 mmHg, Week 15: 112.9 ± 3.2 versus 103.4 ± 2.1 mmHg) and Week 15 in females (115.9 ± 3.7 versus 102.8 ± 0.7 mmHg; all P < 0.05 versus Young-ET). The GTT results and organ allometry were not affected in male offspring. In contrast, Old-ET females displayed a greater (P < 0.05) peak glucose concentration at 30 min during the GTT (21.1 ± 0.4 versus 17.8 ± 1.16 mmol/l) and their spleen weight (88.2 ± 2.6 ± 105.1 ± 4.6 mg) and several organ:body weight ratios (g/g × 10(3)) were decreased (P < 0.05 versus Young-ET), including the heart (3.7 ± 0.06 versus 4.4 ± 0.08), lungs (4.4 ± 0.1 versus 5.0 ± 0.1), spleen (2.4 ± 0.06 versus 3.2 ± 0.1) and liver (36.4 ± 0.6 versus 39.1 ± 0.9). LIMITATIONS, REASONS FOR CAUTION Results from experimental animal models cannot be extrapolated to humans. Nevertheless, they are valuable to develop conceptual models that can produce hypotheses for eventual testing in the target species (i.e. humans). WIDER IMPLICATIONS OF THE FINDINGS Our data show that offspring from mouse embryos from aged mothers can develop altered phenotypes during post-natal development compared with embryos from young mothers. Because all embryos were transferred into young mothers for the duration of pregnancy to normalize the maternal in vivo environment, our findings indicate that adverse programming via AMA is already established at the blastocyst stage. Whilst human embryos display increased aneuploidy compared with mouse, we believe our data have implications for women of AMA undergoing assisted reproduction, including surrogacy programmes.
