[Congenital adrenal hyperplasia causing male infertility. Report of one case].

In males, congenital adrenal hyperplasia due to 21 hydroxylase deficiency is associated to normal fertility or infertility caused by a hypogonadotrophic hypogonadism (HH) or gonadal damage caused by intratesticular adrenal remnants. We report a 29-year-old male with azoospermia, without any important personal or family background. Physical examination was normal, his height was 150 cm and his testicular volume was 10 ml (normal 15 to 25 ml).

[Influence of size and duration of gynecomastia on its response to treatment with tamoxifen].

Background: Gynecomastia is treated when it is painful, there are psychosocial repercussions or it does not revert in less than two years. It is treated with the antiestrogenic drug tamoxifen, but there are doubts about its effectiveness in high volume gynecomastias or in those lasting more than two years.

Aim: To assess the effectiveness and safety of tamoxifen for gynecomastia and the influence of its volume and duration on the response to treatment.

[Etiological study of gynecomastia: results of a prospective study and recommendations].

Background: Gynecomastia can be physiological or pathological. A limited study of gynecomastia is recommended during puberty and in the elderly, ages in which gynecomastia is usually considered physiological. Other authors suggest that this condition should be studied when it is painful, rapidly growing, of recent onset, when its diameter is more than 4 cm and when is associated to testicular masses.
