Genetic Variation in the FSH Signalling Pathway Affects Female Reproductive Hormones During Infancy

Henriksen Louise S , Hagen Casper P , Assens Maria , Almstrup Kristian , Main Katharina M

Background: Studies have shown that genetic variations in the FSH pathway (SNPs: FSHB −211G>T, FSHR −29G>A, and FSHR 2039A>G) affect peripubertal levels of serum FSH and age at pubertal onset in girls.Objective and hypotheses: Genetic variations in the FSH pathway reflect circulating levels of female reproductive hormones during the postnatal gonadotropin surge.Method: Blood samples were taken in girls of th...

Introduction: Brain tumors are the most common solid neoplasm in children, and treatment often includes high-dose irradiation of the central nervous system (CNS). Although not universal, growth hormone deficiency (GHD) is a very common endocrine late effect after CNS irradiation in childhood. The consequences of GHD in adults are many e.g., reduced bone mineral density, fatigue, decreased lean body mass and adiposity, which implies that adults with severe GHD ...

Reproductive hormone levels in Minipuberty as a predictor of Testicular Endocrine Function and Penile Length in Healthy Young Men: An 18-year longitudinal Cohort Study

Background: Minipuberty denotes a period 1–6 months postnatally in boys during which a transient activation of the hypothalamic-pituitary-gonadal axis is observed. This early hormone activation can be used diagnostically in patients suspected of pituitary deficiency and differences in sex development. However, its significance for prediction of reproductive function in healthy young men is unknown.Objective: To eval...

Background: There is increasing evidence from epidemiological studies that some man-made chemicals present in the environment can disrupt endocrine homeostasis in exposed humans. Exposure during foetal life to e.g. phthalates has been linked to adverse effects on testicular and ovarian development, thyroid homeostasis and growth in postnatal life. Exposure to phthalates fluctuates not only from day to day but also over time which poses a major challenge for ex...
