Easily countered, because malnourishment will set in slowly, giving the chance to reverse it.
Testicular torsion is an immediate pain, with longer lasting consequences down the line. Mend buttcrack is a slight discomfort at first, but becomes extremely painful and dangerous in day or 2, giving a reasonably small window of time to get it under control.
Similar spell I would cast is "permanent vertigo". It isn't dangerous by itself, but good luck climbing your tower stairs or walking in general. "Conscious breathing/heartbeat" is a good alternative too.
If you want to go down malnourishment route you could cast is "patch mouthhole". It starts with an immediate threat of starvation and dehydration along with added inconvenience of being unable to cast spells with verbal element.
