Testosterone is produced in female individuals by the ovary, adrenal glands, and peripheral tissues via conversion of androstenedione and dehydroepiandrosterone (pre-androgens synthesized by the ovaries and adrenal glands) to testosterone. Testosterone has both direct and indirect (via aromatization to E2...
Cortisol, 17-OH-progesterone (17OHP), androstenedione (ASD), and dehydroepiandrosterone (DHEA) were assayed in plasma. Baseline cortisol levels were higher in RA patients (RA: 385 ± 38 versus C: 229 ± 28 nmol/L, P= 0.007). In both study groups, ACTH administration increased all the ...
The natural androgens testosterone (TESTO) and dihydrotestosterone (DHT) are formed from conversion of androstenedione into TESTO by 17β-hydroxysteroid dehydrogenase and then TESTO into DHT by the action of the enzyme 5α-reductase. The adrenal precursor 5-androst-5-ene-3 β,17β-diol can also...
Reactive hyperemia was induced by inflating a cuff on the upper arm to a suprasystolic level and then deflating the cuff.Women diagnosed as having PCOS had significantly higher serum levels of luteinizing hormone, testosterone, and androstenedione than control women and significantly lower levels of ...

Testosterone and androstenedione levels exceeded the LOD until the age of 5 months, while the remaining steroids were detectable from month 1 to month 12. In daughters born to mothers with vitamin D deficiency, FSH was detectable in urine for the whole observation period, whereas this was the...
