Infertility is defined as the inability to achieve clinical pregnancy after 12 months of regular, unprotected sexual intercourse. This condition may originate from male or female factors, each necessitating individualized diagnostic and treatment strategies. The emotional burden of infertility often intensifies psychological stress for couples, particularly when undergoing assisted reproductive technology (ART). Recognizing this, the ESHRE Psychology and Counseling Guidelines Development Group has recommended integrating psychosocial support as an adjunct to medical interventions. Consequently, psychological therapies such as cognitive behavioral therapy (CBT), deep breathing (DB), and progressive muscle relaxation (PMR) have been evaluated in clinical trials for their effects on couples’ mental health and pregnancy outcomes. A recent review in *Human Reproduction* synthesizes emerging insights into the neurobiological and physiological mechanisms underlying these interventions.
Research Methodology
The authors conducted a systematic literature search across PubMed, Google Scholar, and the Cochrane Library using a combination of key terms: infertility, assisted reproductive technology, in vitro fertilization, intracytoplasmic sperm injection (ICSI), emotion, psychological stress, cognitive behavioral therapy, psychosomatic therapy, and relaxation. This query included English-language original research and review articles without publication date restrictions, focusing on the mechanistic pathways of stress management techniques. The comprehensive approach ensured coverage of both foundational and recent research to map the evidence landscape.
Neurobiological and Physiological Mechanisms
Neuroimaging studies using functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) have revealed that CBT, DB, and PMR modulate activity in stress-sensitive brain regions, including the prefrontal cortex, amygdala, hypothalamus, and hippocampus. These interventions appear to enhance emotional regulation by dampening hyperactivity in the limbic system and strengthening prefrontal control over stress responses.
Physiologically, consistent practice correlates with reduced levels of stress biomarkers (e.g., cortisol, norepinephrine) and improved mood states, characterized by lower anxiety and depression scores. Since chronic stress disrupts reproductive hormone balance (e.g., altering gonadotropin release and ovarian follicle development) and impairs ART outcomes such as embryo implantation and placental development, mitigating stress through these techniques may alleviate their adverse effects on reproductive processes.
Clinical and Research Implications
Increasing awareness among reproductive healthcare providers, researchers, and clinicians about these mechanisms offers practical benefits. Understanding the neurophysiological pathways enables clinicians to better engage patients in adopting these interventions, fostering adherence and integration into standard care protocols. This knowledge also informs the design of tailored psychosocial support programs, ensuring they address the unique needs of infertile couples while enhancing the methodological rigor of future studies.
By translating these mechanistic insights into clinical practice, stakeholders can optimize the potential of psychological interventions to improve both the psychosocial well-being of patients and the efficacy of fertility treatments. Moving forward, longitudinal studies exploring dose-dependent effects, individual variability in response, and long-term impacts on maternal and child health will be essential to refining personalized intervention strategies and maximizing their clinical utility.
