Testosterone (T) plays a crucial role in various physiological functions in men, and understanding the variations in T levels during the day is essential for diagnosing and treating testosterone deficiency (TD).
The conversion of testosterone into dihydrotestosterone is catalyzed by the 5α-reductase type 2 enzyme which plays a crucial role in the external genitalia virilization. It is encoded by the SRD5A2 gene.
Testosterone replacement therapy (TRT) is commonly used for various causes of androgen deficiency and subsidized by the Pharmaceutical Benefits Scheme (PBS) in Australia when appropriate. In response to a sharp increase in the prescribing of subsidized TRT, the Australian government instituted new, stricter prescription criteria in April 2015.
To estimate the impact on testosterone prescribing over 3 years following the 2015 tightening of Pharmaceutical Benefits Scheme (PBS) criteria.
Analysis of testosterone prescribing data from PBS and private (non-PBS) sources between 2012 and 2018 covering 2015 change in PBS prescribing criteria.
To explore associations between dietary habits and erectile dysfunction (ED) in a cohort of patients presenting to a high-volume men's health clinic.
All patients presenting to a high-volume men's health clinic between July 2018 and May 2019 were evaluated for their dietary habits and screened with the International Index of Erectile Function-5 (IIEF-5) and Androgen Deficiency in Aging Males (ADAM).
Testosterone is the major male hormone produced by testicles which are directly associated with man's appearance and secondary sexual developments. Androgen deficiency starts when the male hormonal level falls from its normal range though, in youngsters, the deficiency occurs due to disruption of the normal functioning of pituitary, hypothalamus glands, and testes.
Off-label testosterone prescribing for androgen deficiency (AD)-like sexual and energy symptoms of older men without pathologic hypogonadism has increased dramatically without convincing evidence of efficacy.
The literature suggests a bidirectional relationship between testosterone (T) and iron, but mechanisms underlying this relationship remain unclear. We investigated effects of iron on advanced glycation end products (AGEs) in obesity-related androgen deficiency.
Serum prostatic specific antigen (PSA) and serum testosterone levels share an undefined relationship with each other, with many conflicting studies showing both positive and negative correlation between them.
The aim of this study is to summarize recently published literature examining androgens and depression.
The impact of androgen levels, androgen replacement therapy and pharmacologic androgen deprivation on depression and depressive symptoms remain active areas of investigation.
