[Relationship between semen quality and anthropometric parameters in males].

A direct and significant linear relationship was found between hip circumference and seminal volume.

• The association was statistically significant at p=0.027
• The relationship was described as a 'direct and significant linear relationship' identified via linear regression models
• This was the only anthropometric parameter found to be associated with any semen quality measure
• 117 men from infertile couples were studied from December 2021 to October 2023

No association was found between the remaining anthropometric parameters and seminal quality.

• Anthropometric parameters assessed included BMI, waist-hip index, and percentage of muscle mass, fat mass, and visceral mass
• Semen parameters were assessed via seminogram (semen analysis)
• Statistical analysis was performed using the Mann-Whitney U test and linear regression models
• The study recruited 117 men from infertile couples attending a Gynecology-Sterility consultation at Hospital of Denia, Spain

Male factors account for up to 30% of infertility cases, which affect 15% of the world's population.

• The paper states 'infertility problems affect 15% of the world's population'
• Male etiology is reported as the cause in 'up to 30% of cases'
• The relationship between male infertility and nutritional status is described as 'inconclusive'
• Most prior studies are noted to rely solely on BMI without considering other body composition parameters

The study comprehensively assessed male body composition using multiple anthropometric parameters beyond BMI.

• Parameters included BMI, waist-hip index, and percentage of muscle mass, fat mass, and visceral mass
• Anthropometric variables were collected by physical examination
• Clinical variables were collected by semen analysis (seminogram)
• The sample consisted of 117 men from infertile couples recruited over approximately 22 months (December 2021 to October 2023) at a single center in Spain
