In the past decade, flow cytometry has emerged as a crucial tool for assessing cellular viability in non-domestic animals, including non-human primates, marine life, and birds. Its application in sperm-quality assessments could revolutionize how we evaluate sperm concentration and viability, enhancing efficiency and reliability. This study validated the effectiveness of flow cytometry in assessing amphibian sperm, demonstrating its viability when compared with traditional, time-consuming methods. Such advancements highlight the potential of flow cytometry to significantly streamline conservation efforts for amphibians. Photograph by Ingrid Niesman, SDSU EM Facility.

To clarify mechanisms of age-related infertility, we evaluated the decreased expression of CSF2, one of the most extensively studied embryokines, in aged bovine uteri compared to young ones. We observed suppressed CSF2 expression and increased myofibroblasts, which may contribute to fibrosis, in the uterine epithelium of older cows compared to young heifers. These findings suggest that decreased CSF2 alongside fibrosis may play crucial roles in age-related infertility, opening avenues for further research into potential therapies targeting fibrosis in reproductive health.

RD24196Physical activity and male reproductive function

A simple flow chart showing factors that lower (on the left) and increase (on the right) male reproductive health.

Exercise is suggested to have a beneficial role in improving the declining fecundity in humans, which is partly due to poor sperm parameters. Literature reports on the benefits of exercise for male reproductive function are, however, equivocal. This review summarises some of the reports and concludes that low-to-moderate intensity exercises, particularly those that do not increase testicular temperature or oxidative stress, are beneficial to male reproductive function.

RD24160Folicular dynamics, endocrine profiles and endometrial gene expression in fertile and subfertile cows

C. Viñoles 0000-0001-8647-4802, A. Álvez, X. González and A. Meikle
 

A diagram showing the differences in progesterone and metabolic hormones between fertile and subfertile cows.

Subfertile cows that get pregnant late in the breeding season are less productive. We found that fertile cows had more fat and muscle, greater circulating concentrations of metabolic hormones, healthy follicles with more granulosa cells and higher insulin-like growth factor 1 in the follicular fluid. Fertile cows had fewer circulating concentrations of progesterone but the sensitivity of the endometrium to progesterone and adiponectin was greater than in subfertile cows. Fertility was associated to the cow metabolism, that regulates uterine function to reduce embryo losses. Diagram adapted from Meikle et al. (2018).

RD24120Selected plant extracts and female fertility: role in the regulation of the hypothalamo-pituitary-ovarian axis in normal and pathological conditions

Plant extracts can be an alternative to treat some female infertility. Female fertility is a complex process regulated by hypothalamic–pituitary-ovarian unit involving both negative and positive feedback mechanisms. Because this hypothalamo–pituitary-ovarian axis is crucial in the regulation of female fertility, this review highlights mechanisms of action of various plant extracts on this axis. Diagram by J. Dupont using BioRender software.

In this review, we explore the limitations on current genetic testing methods for embryos used in assisted reproductive technologies. We highlight the need for new solutions to address these clinical and technological challenges. Furthermore, we discuss a promising approach, metabolic imaging, which could potentially meet these clinical needs and improve the current issues faced by genetic testing for embryo selection.

RD24097Role of resistin in the porcine uterus: effects on endometrial steroidogenesis

Diagram of the role of resistin in the porcine uterus and its effects on endometrial steroidogenesis.

Resistin belongs to adipokines – the group of hormones secreted mainly by the adipose tissue that can regulate not only energy homeostasis but also reproductive functions. We determined the presence of resistin in the uterus and its impact on the uterine steroidogenesis of pigs, an important farm animal. The obtained results suggest that resistin may interconnect metabolism and reproduction, and in the long-term perspective, these results may help improve farm animal breeding efficiency.

This study explores how a mother’s physical activity and diet during pregnancy can shape the long-term health of her offspring, using a rat model. We found that swimming during pregnancy helped protect against weight gain in the offspring, but when combined with a high-fat, high-sugar diet after birth, it disrupted important antioxidant defenses in the offspring’s ovaries. These findings highlight the complex impact of maternal habits on the future health of the next generation. Image by Cristiane Matté using BioRender.

RD24131Identifying the composition of large vesicles in the cytoplasm of oocytes

Electron microscope image of sheep oocyte vesicles and lipid droplets.

Poor egg (oocyte) quality is a leading cause of reduced fertility in humans and animals. Large vesicles within oocytes appear to be important for oocyte quality in animals but their composition is unknown. Our study has identified that these vesicles, which appear empty in electron micrographs, contain lipid that differs to that contained in classical lipid droplets. This knowledge may be used to improve in vitro maturation media to enhance oocyte quality. Image by K L Reader.

RD24086A corollary study to substantiate the therapeutic role of receptor from Shigella flexneri in mitigating the sperm immobilization factor-mediated negative influences on mouse spermatozoa: a molecular mimicry-based approach

Bacteria and human spermatozoa share similar surface proteins. This unexpected connection could be key to understanding certain types of unexplained infertility. This study found that a bacterial protein, sperm immobilization factor (SIF), can damage spermatozoa by binding to it. This protein also binds to the bacteria Shigella flexneri. By isolating the SIF binding receptor from Shigella flexneri, this study opens new avenues for treating infertility, offering hope for many affected couples.

Understanding the intricate dance of hormones in the ovaries is crucial for women’s health and fertility. This review highlights the roles of two short peptides, endothelin-1 and endothelin-2, which govern the life cycle of the corpus luteum – a key gland for maintaining pregnancy. Our findings reveal that while endothelin-2 promotes the formation of this gland, endothelin-1 triggers its demise, together shedding light on the control and regulation of the reproductive cycle and potential treatments for reproductive disorders.

Identifying methods to improve animal health, production, and resilience is critical to create a sustainable food supply to meet global nutritional demand. Recent advancements in gene editing tools, cell culture methods, and in vitro phenotyping can accelerate the identification of variants or novel alleles that are transformative for livestock health and resilience. The use of organoids and gene editing can provide a model to link the genome to the phenome and decrease the number of animals needed for research.

Prediction of bovine IVP embryo viability based on morphokinetic analysis

Conventionally, the quality of bovine IVP embryos is evaluated around day 7–8, and the process is subjective and operator-dependent. A new approach using time-lapse monitoring in specialized culture dishes improves accuracy by continuously tracking individual embryo development. When predicting embryo viability, it is crucial to emphasize the importance of early cleavage stage morphokinetics rather than relying on morphological evaluation based on blastocyst snapshots at the time of transfer.

Non-photoperiodic Actions of Melatonin

Historically, melatonin has been seen as a pineal hormone that plays one essential role – the synchronisation of reproductive and other brain-controlled functions with changes in photoperiod. Often driven by the detection of melatonin receptors in non-brain tissues, it has become clear that melatonin plays a much wider variety of roles in the function of the testis, sperm, ovary, follicles, oocyte, embryo, placenta, fetus and mammary gland. This Collection presents this broader view of melatonin biology, and how the new concepts can be applied to livestock production.
