Abstract
Purpose: To investigate the impact of paternal body mass index (BMI) on semen parameters and assisted reproductive outcomes in couples undergoing their first IVF/ICSI-ET cycle.
Materials and methods: This retrospective study included 7618 couples undergoing IVF/ICSI-ET for maternal tubal/pelvic factors from 2017 to 2023. Paternal BMI was classified according to WHO criteria: normal weight (n = 3433), overweight (n = 3248), and obese (n = 937). Semen quality, embryological outcomes (utilizable/high-quality embryos, blastocysts), and ART outcomes (pregnancy, singleton live birth) were compared. ANOVA, chi-square tests, and multivariate regression were used; subgroup analyses were conducted for IVF and ICSI-ET.
Results: Normal sperm morphology was higher in the normal weight group (5.32 ± 4.92 %) vs. overweight (4.85 ± 3.53 %) and obese (4.79 ± 4.93 %) (P < 0.001). Utilizable embryo rate was higher in the normal weight group (84.22 ± 19.29 %) than in the overweight group (82.98 ± 20.20 %) (P = 0.018). The utilizable blastocyst rate was also higher vs. obese group (29.60 ± 22.61 % vs. 26.93 ± 21.87 %; P = 0.004). Clinical pregnancy rates were 59.2 %, 56.6 %, and 55.5 % in the normal, overweight, and obese groups, respectively (P = 0.037). ICSI subgroup showed limited ART differences except higher birthweight in the obese group (P = 0.003).
Conclusions: Men with normal BMI demonstrated better sperm morphology, embryo utilization, and pregnancy rates. These findings underscore the importance of assessing paternal BMI in ART and support integrating paternal weight management into preconception care.
期刊介绍:
The aim of Obesity Research & Clinical Practice (ORCP) is to publish high quality clinical and basic research relating to the epidemiology, mechanism, complications and treatment of obesity and the complication of obesity. Studies relating to the Asia Oceania region are particularly welcome, given the increasing burden of obesity in Asia Pacific, compounded by specific regional population-based and genetic issues, and the devastating personal and economic consequences. The journal aims to expose health care practitioners, clinical researchers, basic scientists, epidemiologists, and public health officials in the region to all areas of obesity research and practice. In addition to original research the ORCP publishes reviews, patient reports, short communications, and letters to the editor (including comments on published papers). The proceedings and abstracts of the Annual Meeting of the Asia Oceania Association for the Study of Obesity is published as a supplement each year.
