Step 1: Male impotence can be absolute (toward every partner) or selective (toward one specific partner), and forensic medicine has Latin labels for the selective forms.
Step 2: Quoad Hanc literally points to one particular woman: it denotes a man who cannot perform with that specific woman though he is fully potent with others, often on a psychological basis. This matters in petitions for annulment of marriage.
Step 3: Its mirror term, Quoad Hunc, describes a woman unable to consummate with one specific man.
Step 4: None of the remaining choices, which talk of a passive partner, hypersexuality, or pedophilia, correspond to this definition.
