Hyperlipidemia Is Not Related to Semen Quality, but to Serum Testosterone Levels

Background. Currently, there are few studies on the effects of hyperlipidemia on semen parameters and serum hormones in men. In this study, we divided the study subjects into two groups of normal and hyperlipidemia according to the criteria, and observed the differences between semen parameters and serum reproductive hormones in hyperlipidaemic men and normal men, to explore the potential associations between the indicators. Materials and Methods. Eight hundred eighty five men attending infertility clinics in six hospitals from September 2016 to June 2017 were selected. Their lipid levels, semen parameters, and serum reproductive hormone levels were tested, and a total of 480 men with normal lipids and 405 men with hyperlipidemia were selected according to the criteria, and the relationship between semen quality, serum reproductive hormones, lipids and semen parameters, and serum hormones was statistically analyzed. Results. There was no significant difference in semen parameters between hyperlipidaemic men and normal men (P  > 0.05), serum testosterone levels were significantly lower in hyperlipidaemic men (P  < 0.05), and there was a negative correlation between triglycerides (TG) and testosterone in the blood (P  < 0.05).Conclusion. Hyperlipidemia does not affect male semen parameters, and changes in testosterone in hyperlipidaemic men may be related to triglycerides.
