This retrospective study investigated whether body mass index influences sperm fertilization potential in 306 men with primary idiopathic or mild male factor infertility. Researchers assessed the correlation between BMI and conventional semen parameters as well as sperm-zona pellucida binding ability using the zona binding test. The analysis revealed no significant relationship between BMI and either standard semen quality metrics or the specific capacity of sperm to bind to the zona pellucida. Consequently, the authors suggest that any negative impact of male obesity on IVF outcomes likely stems from other defects, such as issues with capacitation or the acrosome reaction. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

Lifestyle factors, such as weight and nutritional status may affect male fertility, including sperm fertilization ability. The objective of this retrospective study was to evaluate the association between body mass index (BMI) and sperm-zona pellucida binding ability assessed according to the zona binding (ZB) test, which has been described to be a relevant diagnostic tool for the prediction of in vitro fertilization (IVF) ability. Three hundred and six male patients from couples diagnosed with primary idiopathic or mild male factor infertility were included. Correlations between BMI and semen parameters according to ZB test indices were assessed, together with frequencies of positive and negative tests across the BMI categories. In this selected population, BMI was not related to conventional semen parameters or sperm quality assessed according to the ability of spermatozoa to bind to the zona pellucida. The previously described poor outcomes of IVF procedures in cases of male obesity could be due to other sperm defects, such as alterations of sperm capacitation or acrosome reaction. The link between male BMI and biological outcomes during IVF procedures, such as fertilization rates, should be further evaluated.
