PMID: 39588946
The CHAARTED study showed that adding docetaxel (Doc) to androgen deprivation therapy (ADT) in men initiating treatment for metastatic hormone-sensitive prostate cancer (mHSPC) prolongs survival, particularly in high-volume disease. Androgens...

191(5):523-534.
PMID: 39575586
Objective: Sociodemographic, lifestyle, and medical variables influence total testosterone (T) and sex hormone-binding globulin (SHBG) concentrations. The relationship between these factors and "free" T remains unclear. We examined 21 sociodemographic,...

Grahnemo L, Marriott R, Murray K, Tyack L, Nethander M, Matsumoto A, et al.
J Clin Endocrinol Metab
. 2024 Oct;
PMID: 39373573
Context: As men age, circulating testosterone (T) decreases, circulating sex-hormone binding globulin (SHBG) increases, and risk of fracture increases. It is unclear if circulating T, independently of comorbidities, is associated...

Yeap B, Marriott R, Dwivedi G, Adams R, Antonio L, Ballantyne C, et al.
Ann Intern Med
. 2024 May;
177(6):768-781.
PMID: 38739921
Background: Whether circulating sex hormones modulate mortality and cardiovascular disease (CVD) risk in aging men is controversial. Purpose: To clarify associations of sex hormones with these outcomes. Data Sources: Systematic...

Ann Intern Med
. 2023 Aug;
176(9):1221-1234.
PMID: 37639720
Background: Various factors modulate circulating testosterone in men, affecting interpretation of testosterone measurements. Purpose: To clarify factors associated with variations in sex hormone concentrations. Data Sources: Systematic literature searches (to...

23(6):1123-1137.
PMID: 36459352
In men > ~35 years, aging is associated with perturbations in the hypothalamus-pituitary-testicular axis and declining serum testosterone concentrations. The major changes are decreased gonadotropin-releasing hormone (GnRH) outflow and decreased...

PMID: 36285783
Background Circulating androgen concentrations in men decline with age and have been linked to diabetes and atherosclerotic cardiovascular disease (ASCVD). A similar relationship has been reported for low total testosterone...

Andrology
. 2022 Oct;
11(1):125-133.
PMID: 36251328
Background: Free testosterone (FT) determination may be helpful in evaluating men suspected of testosterone deficiency especially in conditions with altered binding-protein concentrations. However, methods for measuring FT by equilibrium dialysis...

Endocrinol Metab Clin North Am
. 2022 Feb;
51(1):47-62.
PMID: 35216720
A systematic approach to diagnose hypogonadism initially establishes the presence of symptoms/signs of testosterone deficiency, considers other potential causes of manifestations, and excludes conditions that transiently suppress testosterone. Hypogonadism is...
