Human Sexual Development in the Somatic and Psychosexual Context

Abstract

Human sexual development begins in the prenatal period and continues throughout life, shaped by both biological and psychosocial factors. Somatic development leads to reproductive maturity through several stages regulated by the hypothalamic–pituitary–gonadal axis. Psychosexual development, described in classical theories such as Freud’s and in contemporary models, emphasizes the development of gender identity and sexual behaviors from infancy through early and middle childhood into adolescence, a period characterized by the integration of sexual and emotional components. This developmental trajectory evolves from a biologically driven process into a conscious, socially shaped phenomenon through concretization, mentalization, and socialization. To synthesize current knowledge, this paper is based on a literature review conducted across multiple databases, with studies selected and evaluated for relevance to both somatic and psychosexual development. Understanding the dynamics of these processes is essential for clinical practice, sexual education, and health prevention. It emphasizes integrated clinical practices that employ a multidisciplinary approach, incorporating both medical treatment and psychological support, particularly in the care of children and adolescents with disorders of sexual development. This article presents a comprehensive overview of human sexual development from the prenatal period through adolescence, considering its somatic and psychosexual aspects.
