Free testosterone and cardiometabolic parameters in men: comparison of algorithms

open access: yesEndocrine Connections, 2021
Objective: Calculating the free testosterone level has gained increasing interest and different indirect algorithms have been suggested. The objective was to compare free androgen index (FAI), free testosterone estimated using the linear binding model ...

Reproductive Technologies for Male Infertility [PDF]

open access: yesThe Journal of Clinical Endocrinology & Metabolism, 2001
The introduction of intracytoplasmic sperm injection (ICSI) in 1992 has revolutionized the treatment of male infertility (1) and has allowed couples whose only prior options were donor insemination to achieve pregnancies or adoption. Although in vitro fertilization (IVF) and related procedures have been used in the past for the treatment of male ...

CD47 promotes mitogen‐activated protein kinase and epithelial‐to‐mesenchymal transition molecular programs to drive prometastatic phenotypes in non‐small cell lung cancer

open access: yesMolecular Oncology, EarlyView.
Beyond its role in immune evasion, this study identified that CD47 drives tumor‐intrinsic signaling in non‐small cell lung cancer (NSCLC). Transcriptomic profiling and functional studies revealed that CD47 regulates cell adhesion, migration, and metastasis through an ERK–EMT signaling axis.

Presence of parabens, phenols and phthalates in paired maternal serum, urine and amniotic fluid

open access: yesEnvironment International, 2022
Objective: To examine whether selected endocrine disrupting chemicals were present in pregnant women and passed through the placental barrier to amniotic fluid, potentially exposing the developing fetus.

Aging and the Male Reproductive System [PDF]

open access: yesEndocrine Reviews, 2019
This narrative review presents an overview of current knowledge on fertility and reproductive hormone changes in aging men, the factors driving and modulating these changes, their clinical consequences, and the benefits and risks of testosterone (T) therapy. Aging is accompanied by moderate decline of gamete quality and fertility.

Clinical performance of the urine‐based TERT promoter AbsoluteQ Digital PCR for non‐invasive detection of bladder cancer

open access: yesMolecular Oncology, EarlyView.
A urine‐based digital PCR assay targeting two hotspot TERT promoter variants detected bladder cancer with high sensitivity and no false positives in this case–control cohort. The streamlined AbsoluteQ workflow outperformed Sanger sequencing and supports non‐invasive molecular testing for bladder cancer detection.

Association between single nucleotide polymorphisms, TGF-β1 promoter methylation, and polycystic ovary syndrome

open access: yesBMC Pregnancy and Childbirth
Background Polycystic ovarian syndrome (PCOS) is a common endocrine and metabolic disease in women. Hyperandrogenaemia (HA) and insulin resistance (IR) are the basic pathophysiological characteristics of PCOS.

Deletion in the uridine diphosphate glucuronyltransferase 2B17 gene is associated with delayed pubarche in healthy boys

open access: yesEndocrine Connections, 2018
Objective: Only a few genetic loci are known to be associated with male pubertal events. The ability of excreting testosterone (T) and other steroids in the urine depends on sulfation and glucuronidation.

High Throughput scRNA-Seq Provides Insights Into Leydig Cell Senescence Induced by Experimental Autoimmune Orchitis: A Prominent Role of Interstitial Fibrosis and Complement Activation

open access: yesFrontiers in Immunology, 2022
Leydig cells (Lc), located in the interstitial space of the testis between seminiferous tubules, produce 95% of testosterone in male individuals, which is pivotal for male sexual differentiation, spermatogenesis, and maintenance of the male secondary sex

Metabolism in Male Reproductive Aging

open access: yesAdvances in Geriatric Medicine and Research, 2021
Similar to female reproductive health, male reproductive health declines with increasing age, albeit in a more gradual way. In the US, the average age of first-time fathers has been steadily increasing since 1980. This is concerning because increasing paternal age is positively correlated with reduced sperm chromatin quality and higher numbers of DNA ...
