@ringo @hidden @unliver Nevertheless, I think it's important to understand the scientific basis for gender transition. The practice dates back a long time and is enshrined in common English usage.

For example, consider the two main methods of administration of estrogen: topical and intravenous. They are abbreviated as follows:

e. g. (g = genitalis)

i. e. (i = intravenous)

Any text which features the above abbreviations likely also contains the following:

ibid. (referring to effects on libido, which can be unpredictable)

cf. (cis friend, i.e. trans ally)

Hope this helps ;)
