High-density lipoprotein - HDL
In men, FSH serves to induce spermatogonium development. Determination
of the FSH concentration is used in the elucidation of dysfunctions
within the hypothalamus-pituitary-gonads system. Depressed
gonadotropin levels in men occur in azoospermia (Runnebaum and Rabe,
1994), (M. R. Johnson et al., 1993), (Schmidt-Mathiesen, 1992), (Scott et al.,
1989).
High-density lipoprotein - HDL
HDL cholesterol is used in the assessment of coronary or other vascular

Interpretation
Increased levels
High-density lipoprotein cholesterol (High-density lipoprotein cholesterol
(HDL-C)) levels are increased in the following conditions -
• Hyperalphalipoproteinemia,
• Regular physical activity or exercise,
• Chronic liver disease,
• Weight loss (Williamson, Snyder, and Wallach, 2011).
HDL-C levels are increased in association with moderate ethanol consumption,
insulin, and oestrogen (Williamson, Snyder, and Wallach, 2011).
Additionally, regular aerobic exercise, smoking cessation, decrease in body
mass index, and statin therapy (mild) increase HDL-C levels. Statins or
HMG-CoA reductase inhibitors modestly increase HDL-C levels. The mild
rise in HDL-C levels from these drugs may be related to inhibition of rho-
