Falsely elevated estradiol levels in a young female with iatrogenic menopause

Dias Daniela , Matos Tania , Fontes-Sousa Mario , Silvestre Catarina , Serra Filipa , Sapinho Ines

False elevation of estradiol(E2) due to immunoassay interference is a rare but important phenomenon reported in the literature. It is most commonly related to cross-reactivity(CR) from drugs sharing structural similarity with E2, namely fulvestrant and exemestane. These laboratory interferences(LI) can lead to unnecessary investigation/inappropriate treatments. Therefore, in such instances, a more selective and sensitive method is required. We present the case of a young femal...

Leptin modulates Sertoli cells mitochondrial function and biogenesis with implications for the nutritional support of spermatogenesis

Moreira Bruno M , D Martins Ana , Monteiro Mariana P , Sousa Mario , Alves Marco G , Oliveira Pedro F

Current lifestyle, characterized by physical inactivity and a poor diet, is heavily linked with an increased incidence of metabolic diseases. One of the most serious silent co-morbidities of those diseases is infertility. The hormonal link between food intake and energy homeostasis is mediated by the leptin ghrelin axis. Compelling evidence suggests that direct leptin’s action regulates cellular glucose homeostasis and mitochondrial biogenesis. We have recently shown that...
