Mean platelet volume might be an effective indicator of poor semen quality in varicocele patients.

Abstract

Objective: To delve into the relationship between mean platelet volume (MPV) and semen quality in patients with varicocele.

Materials and methods: A total of 246 varicocele patients and 120 healthy adult males were enrolled. Physical examinations and the color Doppler ultrasonography were conducted on patients with varicocele to confirm the diagnosis. Venous blood samples and semen samples were collected from all participants for subsequent analysis. A series of statistical analyses were conducted to assess the relationship between their MPV levels and semen quality. A series of statistical analyses were performed to assess the relationship between MPV and semen quality.

Results: No statistically significant differences were found between body mass index (BMI), sexual hormones, semen volume, platelet count, and right testicular volume in all three groups (health subjects, varicocele without symptoms, and varicocele with infertility). When conducting regression analysis on two groups with varicocele, the results indicated that a lower MPV is associated with a reduced risk of varicocele accompanied by infertility (OR = 0.557 95% CI: 0.432-0.719, P < 0.001). Further correlation analysis in varicocele patients revealed that high MPV had a statistically negative impact on the occurrence of poor semen quality, affecting sperm concentration, progressive motility, and morphology (all P < 0.001). More importantly, when predicting varicocele associated with infertility, MPV demonstrated high diagnostic sensitivity (AUC = 0.745, P < 0.001).

Conclusion: Our results indicate that MPV is higher in varicocele with infertility and is closely related to semen quality, which may suggest an accompanying decline in semen quality associated with varicocele. However, these conclusions require further experimental validation.
