Varicocele, the most common correctable cause of male infertility, is a progressive vascular pathology characterized by dilation of the pampiniform plexus veins and venous reflux. Multifactorial mechanisms such as venous valve insufficiency, increased intra-abdominal pressure, microcirculatory impairment, and oxidative stress play a role in the pathophysiology of varicocele. Therefore, the present study investigates the clinical effectiveness of a non-invasive rehabilitation approach aimed at regulating intra-abdominal pressure and improving pelvic venous drainage. The study will be conducted using a prospective, randomized controlled clinical design, including male participants aged 18-45 years diagnosed with varicocele. The intervention group will receive visceral osteopathic manual therapy techniques two times per week for eight weeks, while the control group will receive lifestyle recommendations only. Before and after the intervention, semen analysis results, sperm morphology, motility parameters, and testicular venous hemodynamic measurements obtained by color Doppler ultrasonography will be compared. Parametric and non-parametric statistical methods will be used in the analyses.\n\nThis project aims to generate clinical evidence regarding conservative, complementary medicine-based treatment options in the field of male infertility. Compared to studies on female reproductive health, research focusing on male reproductive health is more limited; therefore, this study is expected to contribute to the literature in this area. The results are anticipated to support the development of a cost-effective and accessible model for infertility treatment processes. In addition, the project aims to provide scientific data for the development of sustainable reproductive health approaches in terms of health economics in Türkiye.
