Testosterone use causing erythrocytosis

A FSH-Secreting Pituitary Macroadenoma Causing A Testosterone Deficiency Syndrome

Switch to restoration therapy in a testosterone treated central hypogonadism with erythrocytosis

We describe a case of severe erythrocytosis caused by testosterone replacement therapy in a 66-year-old man affected with hypogonadotropic hypogonadism (HH) determining osteoporosis, resolved by switching to restoration therapy with clomiphene citrate. The patient complained fatigue, loss of libido and defective erections and a spontaneous vertebral fracture despite bisphosphonate therapy and v...

Electrospray mass spectrometry: an efficient method to detect silent hemoglobin variants causing erythrocytosis.

(15:85 by volume). F 2-iPs were eluted by washing the cartridge with 2 mL of hexane– ethyl acetate–propan-2-ol (30:65:5 by volume). For comparing the analytical performance, the samples were also purified by the method described by Nourooz-Zadeh et al. (3) using two solid-phase cartridges. F 2-iPs obtained by the purification procedures were analyzed by gas chromatography–negative ion chemical ...

High serum testosterone levels are associated with excessive erythrocytosis of chronic mountain sickness in men.

Chronic mountain sickness (CMS) is characterized by excessive erythrocytosis (EE) secondary to hypoventilation. Erythropoietin (Epo) and testosterone regulate erythrocyte production. Low thyroid hormone levels are also associated to hypoventilation. Hence, these hormones can play a role in etiopathogeny of EE. The purpose of this study was to elucidate the effect of sexual and thyroid hormones ...

Serum testosterone levels and excessive erythrocytosis during the process of adaptation to high altitudes.

Populations living at high altitudes (HAs), particularly in the Peruvian Andes, are characterized by a mixture of subjects with erythrocytosis (16 g dl(-1)21 g dl(-1)). Elevated haemoglobin values (EE) are associated with chronic mountain sickness, a condition reflecting the lack of adaptation to HA. According to c...
