High testosterone is considered attractive because, theoretically, it signals a strong constitution despite its potential immunosuppressive effects.
Here's a breakdown of why this is believed to be the case:
-
The "Handicap Principle": High testosterone levels have been linked to certain secondary sexual characteristics that are often considered attractive, like a strong jawline, deeper voice, and increased muscle mass. However, testosterone also dampens the immune system.
-
Signaling Superior Genes: The theory suggests that a male who can maintain high testosterone levels and remain healthy signals that he possesses superior genes and a robust constitution. In essence, he's successfully overcome the immunosuppressive "handicap" imposed by testosterone.
-
Implications for Offspring: This perceived strength and resilience are then attractive to potential mates, as they imply that the male will pass these desirable genetic traits to their offspring, increasing the offspring's chances of survival and reproductive success.
In simpler terms, high testosterone is attractive because it suggests "I'm so strong, I can handle having a weaker immune system and still be healthy, and I'll pass this strength on to my kids."
