Lipid studies measure cholesterol and triglyceride levels in the blood. High levels of LDL cholesterol and low levels of HDL cholesterol can contribute to atherosclerosis, where arteries become narrowed and hardened due to plaque buildup. This condition can impair blood flow throughout the body, including to the penis, leading to erectile dysfunction. Regular monitoring of lipid levels is crucial for assessing cardiovascular health and managing risk factors that may contribute to ED.

The EUC test evaluates kidney function by measuring the levels of electrolytes, urea, and creatinine in the blood. Proper kidney function is vital for overall health, including maintaining fluid and electrolyte balance, which can influence blood pressure and vascular health. Impaired kidney function can lead to hypertension and other cardiovascular issues that may affect erectile function. Monitoring these parameters helps in identifying underlying renal issues that could contribute to ED.

The glucose test measures blood sugar levels to assess for diabetes or pre-diabetes. Diabetes is a major risk factor for erectile dysfunction due to its impact on blood vessel health and nerve function. High blood sugar levels can damage blood vessels and nerves over time, reducing blood flow to the penis and impairing the ability to achieve or maintain an erection. Regular glucose testing is essential for early detection and management of diabetes to prevent or mitigate its effects on erectile function.

Testosterone is the primary male sex hormone, and its levels play a critical role in sexual health. Low testosterone levels can lead to decreased libido, fatigue, and erectile dysfunction. This hormone is vital for the development and maintenance of male sexual characteristics and overall reproductive health. Evaluating testosterone levels can help determine if hormonal imbalance is contributing to ED, and guide appropriate treatment options.

LH is a hormone produced by the pituitary gland that stimulates testosterone production in the testes. Abnormal levels of LH can indicate issues with the pituitary gland or testes, affecting testosterone production. Low testosterone levels can lead to erectile dysfunction, reduced libido, and other symptoms. Assessing LH levels helps in understanding the underlying hormonal dynamics and identifying potential causes of ED related to hormonal imbalance.

FSH, also produced by the pituitary gland, is essential for sperm production and overall testicular function. While FSH is more commonly associated with fertility, its levels can provide insights into the functioning of the testes. Abnormal FSH levels may indicate testicular dysfunction, which can indirectly affect erectile function. Monitoring FSH helps in the comprehensive assessment of testicular health and its impact on sexual function.

Prolactin is another hormone produced by the pituitary gland, and elevated levels can negatively impact sexual health. High prolactin levels can suppress testosterone production and libido, leading to erectile dysfunction. Conditions such as prolactinoma (a benign pituitary tumor) can cause elevated prolactin levels. Assessing prolactin levels is important for identifying hyperprolactinemia as a potential cause of ED and guiding appropriate treatment to restore normal hormonal balance.
