[citation needed] The estradiol produced by male humans, from testosterone, is present at serum levels roughly comparable to those of postmenopausal women (14–55 versus <35 pg/mL, respectively). [ citation needed ] It has also been reported that if concentrations of estradiol in a 70-year-old man are compared to those of a 70-year-old woman ...
Both Blackmore and George Cheyne treated this malady as the male equivalent of "the vapours", while preferring the more learned terms "hypochondriasis" and "hysteria". [39] [41] [42] In the late 18th century, the German word Spleen came to denote eccentric and hypochondriac tendencies that were thought to be characteristic of English people. [37]
Hemoglobin in the blood carries oxygen from the respiratory organs (lungs or gills) to the other tissues of the body, where it releases the oxygen to enable aerobic respiration which powers an animal's metabolism. A healthy human has 12 to 20 grams of hemoglobin in every 100 mL of blood. Hemoglobin is a metalloprotein, a chromoprotein, and ...

It affects women more than men due to the sharp fall in estrogen production that follows menopause. [193] Globally, it is estimated that 21.2% of women and 6.3% of men over the age of 50 have osteoporosis, corresponding to a total of around 500 million people worldwide. [194] About 15% of Caucasians in their 50s and 70% of those over 80 are ...
Women have lower hematocrit (the volume percentage of red blood cells in blood) than men; this is due to lower testosterone, which stimulates the production of erythropoietin by the kidney. The normal hematocrit level for a woman is 36% to 48% (for men, 41% to 50%).
[54] [55] Moreover, men with congenital 5α-reductase type II deficiency, 5α-reductase being an enzyme that greatly potentiates the androgenic effects of testosterone in the skin, have little to no acne, scanty facial hair, reduced body hair, and reportedly no incidence of male-pattern hair loss.
