It seems like your question might be a bit unclear or possibly mixed with different concepts. To better understand what you're asking, could you please clarify?
If you're asking why certain fish can be dangerous or lethal to humans, it's important to note that the danger posed by fish (or any animal) isn't determined by gender. Instead, it depends on factors such as the species, size, temperament, and environmental conditions.
For example, some fish can be venomous or aggressive and might pose a threat to anyone, regardless of gender, if threatened or provoked. Additionally, factors like allergies, underlying health conditions, or circumstances could affect an individual's response to a fish encounter.
If your question is about a specific incident or aspect of biology, it would help if you could provide more context for me to assist you better!
