The goal of this clinical trial is to learn whether drinking a daily serving of gazpacho can improve semen quality in men with reduced sperm quality. The study will also examine how this dietary intervention affects oxidative stress and whether it is well tolerated.
The main questions this study aims to answer are:
* Does daily consumption of gazpacho improve semen quality in men with altered semen parameters? * Does this dietary intervention affect levels of oxidative stress in semen? * Is daily gazpacho intake feasible and well tolerated as part of a Mediterranean diet?
Researchers will compare a Mediterranean diet plus daily gazpacho intake with a Mediterranean diet alone to determine whether adding gazpacho provides additional benefits for male reproductive health.
Participants will:
* Follow a standardized Mediterranean diet for 12 weeks * Drink 330 mL of gazpacho every day or follow the diet without gazpacho * Provide semen samples at the start of the study and after 12 weeks * Complete a short diary to record adherence to the dietary intervention * Be followed for up to 18 months to record reproductive outcomes
Men aged 18 to 45 years
Andrological profile including altered semen parameters such as oligozoospermia, asthenozoospermia and/or teratozoospermia (O±A±T)
No clinical indication for sperm DNA fragmentation testing or advanced sperm selection techniques
Willingness and ability to comply with the study protocol, including adherence to a standardized Mediterranean diet
Use of antioxidant supplements during the three months prior to study start.
Active smokers or men who have stopped smoking within the last three months.
Diagnosis of azoospermia, leucocytospermia or necrozoospermia.
Presence of severe systemic diseases or chronic conditions that could interfere with semen quality or adherence to the study.
