Vascular health of fathers with history of intracytoplasmic sperm injection.

Objective: Studies suggest that men who undergo assisted reproductive technologies (ART) may have a higher risk of cardiovascular disease; however, limited data on this matter is available. This observational pilot study aimed to investigate the overall vascular health of fathers with history of intracytoplasmic sperm injection (ICSI) compared to fathers whose partners conceived spontaneously.

Methods: Diet quality, physical activity, sedentary behavior as well as overall vascular function including the assessment of pulse wave analysis, intima-media thickness (cIMT), arterial stiffness of the common carotid artery (CCA) and blood lipids, were evaluated.

Results: A total of 34 fathers with history of ICSI and 29 controls (48.49 [46.32 - 57.09] years 47.19 [40.62 - 55.18] years,  = 0.061) were included. After adjusting for age, no significantly increased cardiovascular risk was detected regarding vascular function.

Conclusions: The results suggest an unaltered cardiovascular risk profile in fathers with history of ICSI. In the future, prospective multicenter studies are required to validate these preliminary results.
