Adolescence or puberty is a period of change in attitudes and behavior from childhood to young adulthood. Adolescence is the most beautiful adjustment period, and almost all adults go through this period with unforgettable memories. Still, it is often accompanied by upheavals and problems, both medical and psychological problems. This study analyzes the relationship between perineal hygiene behavior and reproductive health in adolescents who experience early marriage in Tandonsentul Village, Lumbang District, Probolinggo Regency. This research is quantitative with a correlational design using a cross-sectional study approach with 30 respondents using an accidental sampling technique.
