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...

Background: Minipuberty denotes a period 16 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...
