Autor: Marie Lindhardt Ljubicic, Andre Madsen, Emmie N. Upners, Margit Bistrup Fischer, Alexander Siegfried Busch, Hanne Frederiksen, Trine Holm Johannsen, Anders Juul, Casper P. Hagen
Publikováno v: Frontiers in Endocrinology, Vol 13 (2022)
IntroductionBreast tissue in infancy is a rather undescribed phenomenon. We aimed to describe the prevalence and progression of palpable breast tissue in healthy boys and girls aged 0-1 years and to evaluate clinical markers, individual serum hormone

Exposure to 15 phthalates and two substitutes (DEHTP and DINCH) assessed in trios of infants and their parents as well as longitudinally in infants exclusively breastfed and after the introduction of a mixed diet
Autor: Hanne Frederiksen, Emmie N. Upners, Marie Lindhardt Ljubicic, Margit Bistrup Fischer, Alexander Siegfried Busch, Casper P. Hagen, Anders Juul, Anna-Maria Andersson
Publikováno v: Environment International, Vol 161, Iss , Pp 107107- (2022)
Objective: Several phthalates have been restricted/banned due to their adverse endocrine disrupting properties. The use of other phthalates and substitutes has increased. Here we examine the current exposure to phthalates in family trios comprised of

An Intramuscular Injection of Mixed Testosterone Esters Does Not Acutely Enhance Strength and Power in Recreationally Active Young Men
Autor: Sara Amalie Solheim, Jakob Mørkeberg, Anders Juul, Stine Yde Freiesleben, Emmie N. Upners, Yvette Dehnes, Nikolai Baastrup Nordsborg
Publikováno v: Frontiers in Physiology, Vol 11 (2020)
Purpose: Limited data are available on the acute performance-enhancing effects of single-dose administration of testosterone in healthy humans. Studies of testosterone administrations to healthy humans are rare due to the difficult nature and necessi

Autor: Marie Lindhardt Ljubicic, Trine Holm Johannsen, Margit Bistrup Fischer, Emmie N Upners, Alexander S Busch, Katharina M Main, Anna-Maria Andersson, Casper P Hagen, Anders Juul
Publikováno v: Endocrine Connections, Vol 12, Iss 3, Pp 1-7 (2023)
The ratio between luteinizing hormone (LH) and follicle-stimulating hormone (FSH) has previously been described as an excellent marker of sex in healthy infants. However, LH/ FSH remains not fully described in patients with differences of sex develop

A Biphasic Pattern of Reproductive Hormones in Healthy Female Infants: The COPENHAGEN Minipuberty Study
Autor: Marie L Ljubicic, Alexander S Busch, Emmie N Upners, Margit B Fischer, Jørgen H Petersen, Lars L Raket, Hanne Frederiksen, Trine H Johannsen, Anders Juul, Casper P Hagen
Publikováno v: The Journal of Clinical Endocrinology & Metabolism. 107:2598-2605
Context Minipuberty, a period of a transient activation of the hypothalamic-pituitary-gonadal (HPG) axis in both sexes, enables evaluation of gonadal function in infants suspected of hypogonadism. However, female minipuberty remains poorly elucidated

Dynamic Changes of Reproductive Hormones in Male Minipuberty: Temporal Dissociation of Leydig and Sertoli Cell Activity
Autor: Alexander Siegfried Busch, Marie Lindhardt Ljubicic, Emmie N Upners, Margit Bistrup Fischer, Lars Lau Raket, Hanne Frederiksen, Jakob Albrethsen, Trine Holm Johannsen, Casper P Hagen, Anders Juul
Publikováno v: The Journal of Clinical Endocrinology & Metabolism. 107:1560-1568
Context The male hypothalamic-pituitary-gonadal (HPG) axis is transiently active during the first months of life with surging serum concentrations of reproductive hormones. This period, termed minipuberty, appears to be essential for priming testicul

Publikováno v: Solheim, S A, Levernaes, M C S, Mørkeberg, J, Juul, A, Upners, E N, Nordsborg, N B & Dehnes, Y 2022, ' Stability and detectability of testosterone esters in dried blood spots after intramuscular injections ', Drug Testing and Analysis, vol. 14, no. 11-12, pp. 1926-1937 . https://doi.org/10.1002/dta.3030
While misuse of testosterone esters is widespread in elite and recreational sports, direct detection of intact testosterone esters in doping control samples is hampered by the rapid hydrolysis by esterases present in the blood. With dried blood spot
