Several blood and urine tests can show how well the kidneys are working. For this reason, doctors usually recommend regular tests to keep track of kidney health during treatment. When blood becomes thicker, it can make it harder for the kidneys to filter waste. This can raise blood pressure and put more strain on the kidneys. For example, testosterone can cause the body to hold onto more fluid and salt. Measuring total and free testosterone, along with LH and FSH levels, can help figure out if the problem is in the testicles or the brain’s signaling system. Low testosterone in men with CKD can lead to many health problems. While low testosterone may lead to health issues over time, high levels—especially from testosterone replacement therapy (TRT)—can also cause concerns. These effects may be mild in healthy people but can be dangerous in those with kidney disease. People on testosterone therapy should have their hematocrit levels (a measure of red blood cell concentration) checked regularly. For the kidneys, thick blood can reduce blood flow through the delicate filtering units, leading to reduced kidney function. Another known side effect of testosterone therapy is polycythemia, which means the body makes too many red blood cells. Testosterone is a hormone made mainly in the testicles in males and in smaller amounts by the ovaries in females. Careful monitoring and regular check-ups help reduce these risks and keep treatment safe. Fluid retention, high blood pressure, and thickened blood are the main concerns. But in these cases, treatment must be closely watched by a healthcare provider. While the role of epigenetic modifications in kidney diseases has been extensively studied , its link to sex hormones is still anecdotal and would require further investigation. The sex-related discrepancies observed in clinical and experimental settings of CKD and prominent kidney diseases causing CKD can be explained in part by the effect of sex hormones on the kidney. Although the evidence mentioned above has provided valuable information on the direct and indirect effects of estrogens in the kidney, further research is needed to clarify the relationship between sex hormones and the incidence and progression of diabetic renal disease. By combining gonadal hormones and sex hormone receptor deletions with existing experimental models of renal disease, it may be possible to develop valuable tools for studying sex differences. As many germline loss-of-function mutations in the sex hormone receptors in mouse models lack renal phenotypes, it is conceivable that abnormalities may only become evident under physiological stress, with age, or following kidney injury. This is especially true for people who already have kidney problems or risk factors for kidney disease. Recognizing and managing this imbalance is important for the overall health and well-being of men with kidney disease. Many men with late-stage kidney disease require dialysis, a treatment that removes waste from the blood when the kidneys can no longer do so. As kidney function gets worse, waste products begin to build up in the blood. The kidneys help control blood pressure by adjusting the amount of salt and water in the body and by making hormones that affect blood vessels. These clots can reduce blood flow to the kidneys, which may harm kidney function. Blood samples were taken after an overnight fast in hemodialysis patients (HD group) before a mid-week dialysis session. The study was performed with respect to the Declaration of Helsinki. The study protocol was accepted by the Military Institute of Medicine Bioethics Committee; the number of approval is 107/WIM/2018. There were 38 men on hemodialysis therapy, treated three times a week for more than three months in the HD group. The safety of the therapy was based on the measurement of overhydration and prostate oncological evaluation. The aim of this study was to investigate the safety and efficacy of TRT in men with CKD and hypogonadism coincidence. Understanding how the kidneys work makes it easier to see why keeping them healthy is so important. These tests help doctors decide how healthy the kidneys are and whether treatment is needed. This test estimates how much blood the kidneys filter each minute. If the kidneys are not working well, these substances can build up in the body and cause harm. Besides waste from the body’s own cells, the kidneys also help remove drugs and other chemicals. The kidneys change it into an active form that helps the body absorb calcium from food. Doctors may also check electrolyte levels, such as sodium and potassium, to see if the kidneys are keeping the right balance of minerals in the blood. People with chronic conditions like high blood pressure, diabetes, or heart disease already have higher chances of kidney damage. In some cases, testosterone therapy may also increase the number of red blood cells in the blood. Testosterone therapy can change how the body works in several ways that may affect the kidneys. These hormone changes can affect muscle, bone, mood, and sexual health.
