This LoRA slider was trained on the concept of "male" and "female" related to a person and influes on the physical appearance.
Some of the sample images prompts do not specify the gender so the transition is smooth, from weight -2.0 (womanly) to 2.0 (manly), but specifying a gender in the prompt (like woman for example) and pushing the weight towards the opposite gender yields interresting results too.
