Sex differences are ubiquitous in human development, aging and disease. For example, the overwhelming majority of non-reproductive system cancers are more common in males(Mauvais-Jarvis et al., 2020), while autoimmune diseases are more common in females. Hormones,especially androgens and oestrogens, contribute to sex-biased phenotypes(Khramtsova et al., 2019).
