O yes they do! (Well, Wiki says they do.)

Female prostate gland

The Skene's gland, also known as the paraurethral gland, found in females, is homologous to the prostate gland in males. However, anatomically, the uterus is in the same position as the prostate gland. In 2002 the Skene's gland was officially renamed to female prostate by the Federative International Committee on Anatomical Terminology.[8]

The female prostate, like the male prostate, secretes PSA and levels of this antigen rise in the presence of carcinoma of the gland. The gland also expels fluid, like the male prostate, during orgasm.[9]

^^^^^^^^^^ Not the same. Homologous.

I did read that - but even though it may only be homologous, the renaming of it to "female prostate" makes it so - at least to the extent of females having female prostates.

Wasn't it the APT where the top speed was limited because above

125mph, the possibility of a standing wave in the overhead wire threatened to touch the roof of one or more carriages, as well as being quite destructive to the wiring itself?

[dennis]

Not quite. They couldn't run it with a power car at each end because the wave caused by the front pantograph would cause the trailing pantograph to rip the line down.

This meant they had to put the power car in the middle and effectively cut the train in two.

Another Great British Innovation! How did the Italians make it work, then?

[polygonum]

Non lo so! But this is a (moderately) interesting explanation of Shinkansen.

[dennis]

they didn't solve it. they went around it by putting high voltage cables along the train from one pantograph, something that was deemed unsafe when the APT was being developed.

Dunno about the italians, but this must be why the "225" (Type 91 IIRC) has a power car at the north end only.

Very interesing indeed, actually.
