For this, we performed a retrospective analysis of a large dataset collected from the Shady Grove Fertility (SGF) multicentre practice. All autologous IVF cycles which were followed by at least one single embryo transfer (ET) (fresh and/or frozen) between January 2017 to July 2020, were included. Our study group included patients who had PGT-A and the control group included patients who did not proceed with PGT-A. The primary outcome was the live birth rate (LBR) per transfer. All age-adjusted LBR was higher in the PGT-A group than the non-PGT-A group (48.9% vs. 42.7%, <i>p</i> < 0.001), except in women <35 years old among single embryo frozen ETs. Similarly, LBR in the PGT-A group was higher in all ages except in women <35 years old (48.7% vs. 41.7%, <i>p</i> < 0.001) when all single embryos fresh and frozen ETs were included. In patients of decreased ovarian reserve, transfer of euploid embryo was associated with higher LBR (46.7% vs. 26.7%, <i>p</i> < 0.001) whereas miscarriages were lower in patients with unexplained infertility (9.3% vs. 11.3%, <i>p =</i> 0.007 and endometriosis (8.9% vs. 11.6%, <i>p</i> < 0.001) following euploid embryo transfer.

Semen from Holstein-Friesian bulls (<i>n</i> = 15) was collected and classified into higher (HA, <i>n</i> = 8) and lower (LA, <i>n</i> = 7) antigenic groups based on micro-titer agglutination assay.

Antioxidant activities in seminal plasma and intracellular ROS levels in the post-thawed sperm were estimated. The number of leukocytes was lower (<i>p</i> < .05) in the HA than the LA semen. The percentage of metabolically active sperm was higher (<i>p</i> < .05) in HA than the LA group. The activities of total non-enzymatic antioxidant, superoxide dismutase (SOD) and catalase (CAT) were higher (<i>p</i> < .05) while glutathione peroxidase activity was lower (<i>p</i> < .05) in the seminal plasma of LA group.

A group of mice was treated with AlCl₃ (10 mg/kg b.w./day) and then with NAR (10 mg/kg b.w./day) for a total of sixty-two days. Results show that treatment of AlCl₃ significantly reduced the body weight and testis weight of mice. AlCl₃ caused oxidative damage in mice as evidenced by an increase in the concentration of nitric oxide, advanced oxidation of protein product, protein carbonylation, and lipid peroxidation. Furthermore, diminished activity of antioxidant moieties included superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, reduced glutathione, and oxidized glutathione. Several histological changes, such as spermatogenic cell degeneration, germinal epithelium detachment, and structural abnormalities in seminiferous tubules, were observed in AlCl₃-treated mice. Oral administration of NAR was found to restore body weight and testes weight and ameliorated reproductive dysfunctions. NAR decreased oxidative stress, replenished the antioxidant defense system, and improved histopathological alterations in the AlCl₃-treated testes.

The objective of this pilot study is to test whether untargeted metabolomics is capable of discriminating reproductive outcomes and understand associations between the internal exposome of seminal plasma and the reproductive outcomes of semen quality and live birth among ten participants undergoing assisted reproductive technology (ART) in Springfield, MA. We hypothesize that seminal plasma offers a novel biological matrix by which untargeted metabolomics is able to discern male reproductive status and predict reproductive success. The internal exposome data was acquired using UHPLC-HR-MS on randomized seminal plasma samples at UNC at Chapel Hill. Unsupervised and supervised multivariate analyses were used to visualize the differentiation of phenotypic groups classified by men with normal or low semen quality based on World Health Organization guidelines as well as by successful ART: live birth or no live birth. Over 100 exogenous metabolites, including environmentally relevant metabolites, ingested food components, drugs and medications, and metabolites relevant to microbiome-xenobiotic interaction, were identified and annotated from the seminal plasma samples, through matching against the NC HHEAR hub in-house experimental standard library. Pathway enrichment analysis indicated that fatty acid biosynthesis and metabolism, vitamin A metabolism, and histidine metabolism were associated sperm quality; while pathways involving vitamin A metabolism, C21-steroid hormone biosynthesis and metabolism, arachidonic acid metabolism, and Omega-3 fatty acid metabolism distinguished live birth groups.
