Etymology: < German testosteron (K. David et al. 1935, in Zeitschr. f. Physiol. Chem. CCXXXIII. 281): see testis n.² and -sterone comb. form.

Biology.

a. A steroid hormone that stimulates the development of male secondary sexual characteristics and which is produced in the testes, and, in very much smaller quantities, in the ovaries and adrenal cortex.

ΚΠ

1935 Chem. Abstr. 29 5165 (heading) Crystalline male hormone from testes (testosterone), more active than androsterone prepared from urine or cholesterol.

1939 A. Huxley After Many a Summer ii. vi. 234 With a course of thiamin chloride and some testosterone I could have made him as happy as a sand-boy.

1947 Nature 4 Jan. 15/1 Many mammary cancers would regress when the influence of the female sex hormone was lessened by removal of the ovaries or by injections of testosterone.

1961 New Scientist 9 Nov. 340/1 Naturally occurring steroid sex hormones can inhibit ovulation... Testosterone, progesterone and the oestrogens fall into this group.

1969 Nature 6 Dec. 945/1 Celibacy apparently has no effect on the androgens, for most of the monks excreted as much testosterone—the most potent naturally occurring androgen—as normal sexually active males.

1976 Maclean's 3 May 60/3 Among women virilized in the womb from an excess of testosterone (the male sex hormone), 60% registered IQs over 110.

b. testosterone propionate n. the propionic acid ester of testosterone, given parenterally as a longer-lasting alternative to testosterone.
