Voynich's anatomy

[ololololo]

How come the connections on the tubes aren't symmetric? Is that nymph a fetus with the top of the uterus removed? What's with the cube behind her?

I don't think the growths at the bottom matter, and I don't think they're worth focusing on. Many other items in this section have pipes, branches, etc. This may be a symbol of the organ being "torn off".
The back cube is probably the "pedestal" of the nymph, on which she sits.
Asymmetry may be part of the author's intention. On f83v, the right ball has a longer tube than the left, and while this can be explained in the case of the testicles (the right testicle is attached to the intestines, while the left is not), the reason for this is unclear in the case of the eyeballs.
