The maximum storage time before measurement was 4 days. Statistical Analysis The results are expressed as means±SD. Statistical analysis of the data was performed using the SAS 6.12 program pack- age (SAS Corp., Cary, USA). The results were analyzed using analysis of variance, Student's t-...
while others may cause damage to the liver or kidneys, leading to an even more serious condition. It is possible to get the blood flow back to normal with the use of some medications, such as antibiotics, but not necessarily all. A prolonged use of a drug may even lead to complications...
Diagnosis of penile vascular insufficiency may be suspected by Doppler ultrasound measurement of the ratio of penile to brachial systolic blood pressure (penile/brachial index). A penile/brachial index greater than 0.75 is normal, whereas an index of less than 0.60 is suggestive of vascular erectile...
Moreover, measurement of bioavailable testosterone, a combination of albumin-bound and free testosterone, also has clinical utility and can be measured by selective protein precipitation or calculation. In this review, the advantages and limitations of each of these methods will be discussed in the ...
but prevention also means having a doctor to work with for things like blood work and blood pressure measurement. If you are someone who has a bad experience in the medical world, or worse, someone who is denied care due to your gender or sexuality, that person will often have worse outco...

Measurement of the serum testosterone concentration is usually the most important single diagnostic test for male hypogonadism because a low value usually indicates hypogonadism. Measurement of the serum total (free plus protein-bound) testosterone concentration is usually an accurate reflection of testostero...
On the 7th week of treatment, blood samples were collected for coagulation parameters analysis and measurement of plasma testosterone levels. Moreover, quantitative real-time PCR analysis was performed on liver samples to assess the expression of factor IX, factor X, and prothrombin genes. The ...
Hence, a single blood testosterone measurement by any assay does not constitute a diagnosis of chronic androgen deficiency. The inaccuracy and method-dependence of commercial semi-automated platform immunoassays for testosterone [7, 8] and of so-called ‘free testosterone’ [9] is now well ...
