Women with nonclassic 21-hydroxylase deficiency can have successful pregnancies through IVF, with certain factors affecting their chances.
research Conversion of C57Bl/6 mice from a tumor promotion–resistant to a –sensitive phenotype by enhanced ornithine decarboxylase expression
Increased ODC expression makes normally tumor-resistant mice more prone to tumor development.
research Total testosterone to dihydrotestosterone ratio assessed by LC-MS/MS predicts a worse metabolic profile not only in PCOS patients
A higher testosterone to dihydrotestosterone ratio may indicate worse metabolic health in women.
research Biomonitoring of arsenic, lead, manganese and mercury in hair from a presumably exposed Uruguayan child population

research Sequential Hair Shaft as an Indicator of Prior Mineralization in the Alaskan Moose2
Moose hair can track past mineral levels, except zinc.
research Invalidation of a commercially available human 5α-dihydrotestosterone immunoassay
The DHT immunoassay is unreliable due to high cross-reactivity with testosterone.
research FGF signaling for hair cycle resting phase alleviates radiation alopecia
FGF18 treatment during hair's resting phase can protect against hair loss from radiation.
