    Highly Cited Articles in the Field of Male Infertility and Antioxidants: A Scientometric Analysis
    (Worlds J Mens Health, 2021) Agarwal, A; Selvam, MK; Baskaran, S; Finelli, R
    Purpose The objective of this scientometric analysis was to recognize the top 100 cited articles on ‘Male infertility and Antioxidants’ and analyze its publication characteristics. Materials and Methods The Scopus database was used to retrieve related articles and the top 100 identified based on citation rate. Results The articles were published in 56 journals between 1995 and 2019 with a median (interquartile range) citation score of 17 (5–62). Among the top 100 articles, 69 were clinical studies, which included controlled and blinded (33.33%), prospective (27.54%), randomized-controlled trials (26.09%), uncontrolled (11.59%), and retrospective (1.45%) studies. In addition to conventional semen parameters, advanced sperm function tests such as oxidative stress (51%) and sperm DNA damage (23%) were reported. Pregnancy rate (33%) was found to be the most reported reproductive outcome. Antioxidant therapy was mostly investigated in male cohorts with sperm abnormalities such as asthenozoospermia (28%) and clinical conditions such as idiopathic male infertility (20%), varicocele/varicocelectomy (17%) and general male infertility (16%). Conclusions The most influential publications on antioxidants and male infertility were identified for the first time in the literature. This will serve as a reliable source of information for researchers and clinicians alike.

    Obesity and male infertility: Mechanisms and management
    (Blackwell Publishing Ltd, 2021) Leisegang, K; Sengupta, P; Agarwal, A
    Obesity is considered a global health problem affecting more than a third of the population. Complications of obesity include cardiovascular diseases, type 2 diabetes mellitus, malignancy (including prostatic cancer), neurodegeneration and accelerated ageing. In males, these further include erectile dysfunction, poor semen quality and subclinical prostatitis. Although poorly understood, important mediators of obesity that may influence the male reproductive system include hyperinsulinemia, hyperleptinemia, chronic inflammation and oxidative stress. Obesity is known to disrupt male fertility and the reproduction potential, particularly through alteration in the hypothalamic-pituitary-gonadal axis, disruption of testicular steroidogenesis and metabolic dysregulation, including insulin, cytokines and adipokines. Importantly, obesity and its underlying mediators result in a negative impact on semen parameters, including sperm concentration, motility, viability and normal morphology. Moreover, obesity inhibits chromatin condensation, DNA fragmentation, increases apoptosis and epigenetic changes that can be transferred to the offspring.

    An online educational model in andrology for student training in the art of scientific writing in the COVID-19 pandemic
    (Blackwell Publishing Ltd, 2021) Leisegang, K; Agarwal, A; Panner Selvam, M.K
    In 2020, the COVID-19 pandemic led to the suspension of the annual Summer Internship at the American Center for Reproductive Medicine (ACRM). To transit it into an online format, an inaugural 6-week 2020 ACRM Online Mentorship Program was developed focusing on five core pillars of andrology research: scientific writing, scientific methodology, plagiarism understanding, soft skills development and mentee basic andrology knowledge. This study aims to determine mentee developmental outcomes based on student surveys and discuss these within the context of the relevant teaching and learning methodology. The mentorship was structured around scientific writing projects established by the team using a student-centred approach, with one-on-one expert mentorship through weekly formative assessments. Furthermore, weekly online meetings were conducted, including expert lectures, formative assessments and social engagement. Data were collected through final assessments and mentee surveys on mentorship outcomes. Results show that mentees (n = 28) reported a significant (p <.0001) improvement in all criteria related to the five core pillars. These results illustrate that the aims of the online mentorship program were achieved through a unique and adaptive online educational model and that our model has demonstrated its effectiveness as an innovative structured educational experience through the COVID-19 crisis.
