    Smoked or bewitched? the relationship between cannabis use and mental illness among the shona persons in Zimbabwe
    (Springer, 2025) Maja, Jakarasi
    The metanarrative of biomedicine and “psy” discipline (psychology, psychoanalysis, psychiatry etc.) asserts that cannabis use is one of the fundamental causes of mental illness among different men in the Rushinga district of Zimbabwe. These metanarratives, however, appear to have universalised, medicalised and marginalised the conception and representation of mental illness as enmeshed in local epistemologies and ontologies of mental illness. Based on local epistemologies, elders in Diwa largely trace mental illness to discursive sociocultural explanations rarely linked to cannabis use. This paper answers the central question: How is the use of cannabis by different persons related to mental illness in the Rushinga district? I argue that community members, health providers and police officers want to think of persons, especially men, with mental illness as “mad” and immoral cannabis users who brought illnesses upon themselves and lack personal responsibility based on Western neoliberal and biomedical metanarratives. However, this framing is not helpful, it is detrimental to treatment and social reputation, as it bypasses local cultural explanations that may be protective and that offer clearer guidelines for treatment. © The Author(s) 2025.

    Male fertility and the COVID-19 pandemic: Systematic review of the literature
    (Korean Society for Sexual Medicine and Andrology, 2020) Leisegang, Kristian; Khalili, Mohammad Ali; Majzoub, Ahmad A.
    Purpose: Since its discovery in December 2019, the novel coronavirus SARS-CoV-2 has spread globally, causing the current COVID-19 (coronavirus disease-19) pandemic. As there is an increase of infections in the male population, concerns have emerged about the potential impact of COVID-19 on male reproductive organs and male fertility. Therefore, this study systematically investigates the current evidence of SARS-CoV-2 impact on male reproduction and pregnancy outcomes, discussing them in light of the evidence published on other coronaviruses. Materials and Methods: Literature search was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A total of 24 original articles were included for the analysis, investigating the effects of the infection on semen parameters, male reproductive hormones, and pregnancy outcomes.

    Obesity is associated with increased seminal insulin and leptin alongside reduced fertility parameters in a controlled male cohort
    (BioMed Central, 2014) Leisegang, Kristian; Menkveld, Roelof; Bouic, Patrick J.D.; Henkel, Ralf
    Obesity appears to be associated with male reproductive dysfunction and infertility, although this has been inconsistent and inconclusive. Insulin and leptin are known mediators and modulators of the hypothalamus-pituitary-testes axis, contributing to the regulation of male reproductive potential and overall wellbeing. These hormones are also present in semen influencing sperm functions. Although abdominal obesity is closely associated with insulin resistance (hyperinsulinaemia), hyperleptinaemia and glucose dysfunction, changes in seminal plasma concentrations of insulin, leptin and glucose in obese males has not previously been investigated.
