Correlation of Seminal Parameters with Serum Lipid Profile and Sex Hormones

The phospholipids and fatty acid composition of sperm are altered under the influence of serum lipids on impaired seminal parameters in infertile men. We studied the correlation of the serum lipid profile and sex hormone results of a group of infertile men with sperm characteristics of 18 infertile men. Semen samples were collected and analyzed. Serum fasted and post-meal glucose levels, insulin, total cholesterol, HDL, LDL, VLDL, triglyceride, FSH, LH, and testosterone measurements were performed. The increased serum VLDL, total triglyceride, and testosterone values were significantly correlated with decreased sperm motility. Serum FSH values were also inversely correlated with normal sperm morphology. The increased VLDL impaired seminal parameters; additionally, increased triglycerides may have deleterious effects on spermatogenesis. Deterioration is related with increased serum VLDL and triglyceride levels.
