Treatment of hypogonadism is directed at the underlying pathology where possible, helping the woman become fertile if desired, hypogonadisme hypergonadotrope fsh preventing the long-term complications of hypoestrogenism ie, osteoporosis, increased cardiovascular hypogonadisme hypergonadotrope fsh, and urogenital atrophy. Similarly to ovarian function in women the gonadotropins, particularly LH, play a key role in the differentiation and maturation of testis in men. The risk is greater with a younger age of onset. The main target of gonadotropins in females is the ovary, maturation of which is triggered by LH and FSH at puberty. The effect of a null mutation in the follicle-stimulating hormone receptor gene on mouse reproduction.

During follicular growth the earliest signs of FSHR and Fshr expression have been detected in the cuboidal granulosa cells of the primary follicles with a subsequent increase in more advanced follicles [ 1920 ]. The early involvement of FSH in initial folliculogenesis is further emphasised by the data showing that anti-FSH treatment of hamster dams during pregnancy leads to reduced number of primordial follicles in pups [ 13 ] and that the amount of naked oocytes is substantially reduced in 2-day-old FSHR-deficient Forko mice.

Treatment hypergoadotrope HH is usually with hormone replacement therapyconsisting of hypogonadisme hypergonadotrope fsh and estrogen administration in males and females, respectively. Both absent and increased FSH and LH action results in a reduced number of small growing follicles, and the augmented gonadotropin action leads to defects in the remaining follicles see below.

Cancer Cell. Gonadotropins, hypogonadisme hypergonadotrope fsh particular LH, are suggested to exert their effect via receptor binding on several extra-gonadal hypognadisme. The gain-of-function mouse lines demonstrate how a modest increase in FSH action can enhance fertility, but how more excessive and chronic gonadotropin action, of both FSH and LH, leads to accelerated loss of the primordial follicles, improper follicle development, enhanced ovarian hormone production, anovulation, and finally to disruption of the function of the hypothalamic-pituitary-gonadal axis. Presence and absence of follicle-stimulating hormone receptor mutations provide some insights into spontaneous ovarian hyperstimulation syndrome physiopathology.

However, in all of the mouse strains the pituitary disorders are apparently secondary to increased gonadal hormone production. The number of Leydig cells and concentration of intratesticular testosterone increase slowly in Forko mice after puberty and are significantly reduced in adult animals [ 48 ]. In pubertal Forko [ 14 ] and adult hypogonadal hpg [ 16 ] mice that are lacking both LH and FSH, the number of primordial follicles is higher than in age-matched wild-type mice, and gonadotropin treatment of the hpg females causes an accelerated decrease of the follicular pool.
