FSH and bone: comparison between males with central vs primary hypogonadism

Giovanelli Luca , Cangiano Biagio , Colombo Stefano , Persani Luca , Quinton Richard , Bonomi Marco , Chiodini Iacopo

Background: Recent data suggest a direct effect of follicle stimulating hormone (FSH) on the skeletal metabolism. Particularly, it can encourage bone resorption and also inhibit osteoblast differentiation. High FSH levels have been found to correlate with impaired bone health in females, whilst evidence in males remains somewhat poor and conflicting. Intriguingly, men with primary and central hypogonadism might represent a novel study model in this context.<p class="abstex...

Crosstalk between androgen-ZIP9 signalling and key regulators of mitochondrial dynamics in rodent leydig cells

Brzoskwinia Małgorzata , Kamińska Alicja , Lustofin Sylwia , Hejmej Anna , Bilińska Barbara

Androgen signalling plays a central role in the regulation of male reproduction. Androgens act predominantly by activating the classical intracellular androgen receptor (AR). In addition, alternative pathways may account for rapid effects of androgens via cytoplasmic or membrane-localized androgen receptor − ZIP9. In the testis, the main source of androgens, in particular testosterone, are Leydig cells. The proper synthesis of testosterone depends on the structural condi...

Comparison of three different AMH assays with AMH levels and follicle count in women with polycystic ovary syndrome

Moolhuijsen Loes , Louwers Yvonne , Laven Joop , Visser Jenny

Anti-Müllerian hormone (AMH) levels strongly correlate with the number of antral follicles in the ovary. In women with polycystic ovary syndrome (PCOS), this is reflected by significantly increased serum AMH levels. AMH levels are therefore suggested as a proxy for polycystic ovary morphology (PCOM) in PCOS diagnosis. Different assays are available to measure serum AMH levels. However, lack of a golden standard and the use of different antibodies to detect AMH, have led t...

Polycystic ovary syndrome (PCOS) is the most common endocrine and metabolic disorder affecting women in reproductive age. Women with PCOS exhibit 2-3x higher levels of circulating Anti-Müllerian Hormone (AMH) as compared to healthy women and it is unclear if the elevation of AMH is a bystander effect or is driving the condition. Moreover, PCOS has a strong heritable component, however the etiopathology of the disease and the mechanisms underlying its transmission remain t...
