It's nature's way of continuing the species.
the males compete to fertilize
I am a male but I'll have to be honest. The answer to this question is that this is the difference of hormones which makes men/males so angry and aggressive. And also i want to say that the females have more maturity than males because the puberty in women/females starts earlier than males, and as you know puberty is a step to maturity and responsibilities.
Yes, but mostly males. Males attack each other unusually to take over another males pride. Also, when new males take over the pride they kill the cubs for the females to reproduce them. Also, males fight over females. Also females attack males and other females to steal meals or just to show off. so that's why lions do attack other lions or lionesses.
"Although the number of males undergoing liposuction has increased in the last couple of years, it is still females who undergo more liposuction than males."
Your question is wrong as there are various types of hernia . Males have inguinal hernia which can't occur in females .On the other hand females have femoral hernia not present in males .
