Pregnenolone (PREG) can potentially be abused by athletes to maintain an equilibration of the steroidal environment after sex steroids administrations. Five men volunteers orally ingested 50 mg PREG to determine optimal urinary markers for detection of this steroid. Our findings show that ingestion of PREG has no significant effects on the testosterone/epitestosterone (T/E) and testosterone/luteinizing hormone (T/LH) ratios, whereas variable changes on the carbon isotopic values of three T… 
Investigations on changes in ¹³C/¹²C ratios of endogenous urinary steroids after pregnenolone administration.
TLDR
Due to its properties to disguise the misuse of anabolic steroids by influencing the ¹³C/¹²C ratio of PD, PREG should be considered to be added to the World Anti-Doping Agency (WADA) list of prohibited substances as a masking agent.
Impact of progesterone administration on doping test of endogenous steroids
TLDR
The influences of oral and intramuscular administration of PROG on the urinary steroid profile and carbon isotope ratios of steroids were investigated and it was demonstrated that the urine concentrations and the δ13C-values of PD were affected obviously.
Investigations on hydrogen isotope ratios of endogenous urinary steroids: reference-population-based thresholds and proof-of-concept.
TLDR
The obtained results enabled the calculation of the first reference-population-based thresholds for HIR of urinary steroids that can readily be applied to routine doping control samples and proved to be a new tool supporting modern sports drug testing procedures.
Carbon isotope ratio analysis of endogenous glucocorticoid urinary metabolites after cortisone acetate and adrenosterone administration for doping control.
TLDR
This study reaffirms that CIR methods for the doping control of endogenous steroids should not rely upon a single ERC, as the administration of an appropriate precursor to that ERC could cause complications during analysis.
Carbon isotope ratio mass spectrometry for detection of endogenous steroid use: a testing strategy.
Isotope ratio mass spectrometry (IRMS) testing is performed to determine if an atypical steroid profile is due to administration of an endogenous steroid. Androsterone (Andro) and etiocholanolone
A simplified and accurate method for the analysis of urinary metabolites of testosterone-related steroids using gas chromatography/combustion/isotope ratio mass spectrometry.
TLDR
These carefully controlled analytical conditions are compatible with routine operations, affording accurate and precise results for the more diagnostically relevant metabolites such as testosterone itself and the 5α- and 5β-androstanediols.
Discriminating the endogenous and exogenous urinary estrogens in human by isotopic ratio mass spectrometry and its potential clinical value
TLDR
Stable carbon isotope analysis can distinguish the endogenous and exogenous urinary estrogen in human from progesterone, 17α-hydroxyprogesterone, pregnanediol and ethinylestradiol from contraceptives.
Testosterone and doping control
TLDR
An overview of the use of anabolic-androgenic steroids in sport and methods used in anti-doping laboratories for their detection in urine, with special emphasis on doping with testosterone, is given.

Plasma and urinary markers of oral testosterone undecanoate misuse
TLDR
Unchanged TU was directly detected in plasma of all six subjects from 1 approximately 1.5 h to 4 approximately 6 h after oral TU intake by GC/MS/MS, providing unequivocal proof of exogenous testosterone intake.
Androstanediol and 5-androstenediol profiling for detecting exogenously administered dihydrotestosterone, epitestosterone, and dehydroepiandrosterone: Potential use in gas chromatography isotope ratio mass spectrometry
TLDR
The isolation, purification, and isotope ratio mass spectrometry techniques described may form the basis of a general method for confirming natural steroid misuse by sports participants.
Confirming testosterone administration by isotope ratio mass spectrometric analysis of urinary androstanediols
TLDR
A ratio of delta 13C0/1000 for androstanediols to pregnanediol as a useful discriminant of testosterone misuse, a value above 1.1:1.0 being indicative of such misuse is proposed.
Urinary analysis of four testosterone metabolites and pregnanediol by gas chromatography-combustion-isotope ratio mass spectrometry after oral administrations of testosterone.
TLDR
Measurements of 5 beta-androstanediol delta-values allow the detection of a testosterone ingestion over a longer post-administration period than other T metabolites delta(13)C-values or than the usual T/E ratio approach.

Oral administration of dehydroepiandrosterone to healthy men: Alteration of the urinary androgen profile and consequences for the detection of abuse in sport by gas chromatography-mass spectrometry
TLDR
In agreement with reported data found in blood, conversion of exogenous DHEA to the principal biologically active androgen, testosterone, was low but proven to be real by the administration of deuterium-labeled DHEa and the subsequent identification and quantification of deuterspecific testosterone.
Serum and urinary markers of exogenous testosterone administration
Assessment of porcine and human 16-ene-synthase, a third activity of P450c17, in the formation of an androstenol precursor. Role of recombinant cytochrome b5 and P450 reductase.
TLDR
It is demonstrated that human P450c17, as other enzymes of the classical steroidogenic pathway, is involved in the biosynthetic pathway leading to the formation of androstenol.
Criteria to indicate testosterone administration.
TLDR
This study showed that both T/E and T/LH ratios could be used to detect testosterone administration, the latter also being an indicator of HCG use due to cross-reactivity with the LH antiserum.
