Scientists gave male mice a special form of estrogen and they lost weight, but that weight loss didn't make them live longer - female mice also lost weight but didn't get any lifespan benefit from it.

A special form of estrogen called 17-alpha-estradiol helped male mice live longer, but female mice given the same amount didn't get any lifespan benefit.
