A dated or technical term for a naturally occurring estrogenic hormone; historically used in biochemistry and endocrinology.
Linguistics
Semantic Notes
"Estrin" is an archaic spelling largely superseded by the standard term "estrogen" for the class of hormones, and specifically by "estrone" for the C18H22O2 hormone. It may appear in historical medical or biochemical texts.
Dialectal Variation
British vs American Usage
Differences
No significant contemporary difference as the term is largely obsolete in both varieties. Historical usage was parallel.
Connotations
Purely technical and dated. Might be recognized by specialists in medical history or older literature.
Frequency
Extremely rare in modern discourse in both BrE and AmE. The modern term "oestrogen" (BrE) / "estrogen" (AmE) is universally used.

FAQ
Frequently Asked Questions
No, it is an obsolete variant. The correct modern terms are 'estrogen' (AmE) / 'oestrogen' (BrE) for the hormone class, and 'estrone' for the specific hormone once called 'estrin'.
'Estrin' was a specific early name for what we now call estrone, one type of estrogen. 'Estrogen' is the broader class name for all related hormones.
Only in historical scientific or medical literature from the early to mid-20th century. It is not used in contemporary writing.
Only for passive recognition if you are reading old biochemistry texts. For active vocabulary, learn 'estrogen', 'oestrogen', and 'estrone'.
