I am trying to draw a sphere with a handle similar to the one I have attached below with the package TikZ. Unfortunately, while I know how to draw a sphere or a torus, I don't know how to put them together without making a mess. Any kind of help or suggestion is very welcome, thanks.
So, for instance a sphere would be generated by a simple code as the one below, how to attach to this picture handle is however beyond my capacity at the moment
documentclass[a4paper,11pt]article
usepackage[T1]fontenc % if needed
usepackage[english]babel
usepackagegraphicx
usepackagetikz
begindocument
begintikzpicture[baseline]
shade[ball color = gray!40, opacity = 0.4] (0,0) circle (2cm);
draw (0,0) circle (2cm);
draw[dashed] (-2,0) arc (180:0:2 and 0.2);
draw[dashed] (-2,0) arc (180:0:2 and -0.2);
endtikzpicture
enddocument
this code produces

Welcome to TeX.SX! Please help us help you and add a minimal working example (MWE) that illustrates your problem. Reproducing the problem and finding out what the issue is will be much easier when we see compilable code, starting withdocumentclass...and ending withenddocument.

How spherical does the sphere have to be? You could draw a topologically equivalent picture fairly easily using the tqft package.

It would be simpler is the torus intersected the sphere perpendicularly. You can use a pgfplots version of a torus with a reduced domain, Then all you have to do is place the center of the torus on the surface of the sphere.

This is a TikZ (and not asymptote) question. With TikZ one can certainly get some aspects of this right, but getting all of it right is arguably very hard. So this is a compromise.
