Male and female infertility has become a worldwide public health problem. The global obesity epidemic has paralleled a decrease in semen quality. Yet, the association between body mass index (BMI) and sperm parameters remains controversial. The objective of this study is to determine the link between body mass index and seminal parameters. We made an observational study and retrospective analysis. Men who made semen analysis during the period of January 2015 to September 2021 in Reims University Hospital, were included. A total of 1 655 patients were recruited and separated into five groups according to BMI values. Second- and third-degree obesity had a significantly higher risk of having a pathological sperm count (p: 0,0038). Second- and Third-degree obesity was associated with a pathologic vitality (p: 0,012). No significant differences existed between sperm mobility and body mass index. Regarding low body mass index, a significant difference exists on the sperm morphology (p: 0,013). Sperm morphology is also impacted in overweight and obesity groups. The information of the couples on weight is necessary to improve sperm parameters, spontaneous pregnancies and efficacity of assisted reproductive technic.
