Beyond body mass index: the role of fat distribution in male sperm quality.

ABSTRACT:

Objective

To explore the dual role of obesity and fat distribution on sperm dynamics and morphological parameters and to further assess the impact on male fertility.

Methods

A population of 823 male semen examinations from the Male Reproductive Health Database (FAST-Date, 2022-2025), was retrospectively analyzed for general information, obesity indicators, sperm dynamics and morphology parameter ratings, and male fertility assessment indicators.

Results

There were differences in sperm dynamics and sperm morphology parameters between the non-obesity and obesity group populations (P < 0.05), which were shown to be poorer in both sperm dynamics parameters in the obesity group population as compared to the non-obesity group population, and morphological parameters.
