The Concept of Neuro-Behavioral Digital Shift in Reproductology: Digital Infertility, Behavioral Digital Contraception and the PRMPDigital Clinical Protocol

Background: Contemporary reproductive medicine faces a growing category of secondary infertility that is unrelated to anatomical, genetic, or primary hormonal pathologies. Physically healthy couples with normal semen parameters, ovarian reserve, and tubal patency fail to achieve pregnancy due to critically impaired sexual behavior driven by digital environment exposure. Objective: To introduce and define the concept of Neuro-Behavioral Digital Shift (NBDS) — a systemic dysfunction of the reproductive neuroendocrine axis caused by the complex impact of digital environments on human behavior, neurobiology, and hormonal homeostasis — and to propose a corresponding clinical nomenclature and management protocol. Nomenclature Proposed: This preprint introduces the following original terms: Digital Infertility (DI), Behavioral Digital Contraception (BDC), Digital Sexually Transmitted Disorder (D-STD), Digital Libido Atrophy (DLA), Phantom Fertility Syndrome (PFS), Algorithmic Reproductive Procrastination (ARP), and Conception Distraction Syndrome (CDS). Methods (Pathogenesis): NBDS mechanisms operate at three levels: (1) neurotransmitter — dopamine receptor desensitization via digital hyperstimulation leading to reduced response to real partners; (2) neuroendocrine — digital stress-induced HPA axis activation reducing kisspeptin and GnRH pulsatility, causing functional anovulation or impaired spermatogenesis; (3) behavioral — phubbing-induced oxytocin deficit reducing spontaneous intercourse frequency. Diagnostic Tool: The HDIS v1.0 (Hudziak Digital Infertility Scale) is proposed as a 4-domain screening instrument (digital time, sexual desire, digital stress, phantom fertility syndrome; max. 27 points). The scale requires psychometric validation. Protocol: The PRMP-Digital (Predictive Reproductive Management Protocol — Digital) is a 4-phase clinical algorithm comprising: (I) Neuro-Reproductive Screening; (II) D-Detox Protocol (digital silence, sensory reintegration, chronobiological synchronization); (III) Cognitive Behavioral Reproductive Therapy (CBRT); (IV) ART/IVF integration. Limitations: This is a conceptual preprint based on retrospective clinical observations (n>500) without a control group. All proposed mechanisms and the clinical protocol require verification in prospective randomized controlled trials. Conclusions: Digital environment constitutes a clinically significant, modifiable factor in reproductive medicine that warrants systematic assessment in all cases of unexplained infertility. Integration of digital lifestyle evaluation into standard reproductive history-taking is recommended. © Viktoriya Hudziak, 2026. All Rights Reserved. ORCID: 0009-0000-4863-2750.
