So many bad consequences for messing around with women’s hormones.

Birth Control Pills can Limit Muscle-Training Gains.
Some female athletes may pay a price for using oral contraception: lower strength gains from resistance exercise. These muscle-building exercises depend on lifting weights (like barbells and those in the big machines at your local gym) or working against tension bands and bars (like those in Bowflex devices).
Personal trainers have long noted that all women don’t garner the same benefits from such exercise and there has been a suspicion that genetics might underlie differences. But exercise physiologist Chang Woock Lee and his colleagues at Texas A&M University wondered if other lifestyle factors might also play a role. And at the Experimental Biology meeting in New Orleans, this week, Lee identified birth control pills as a major suspect.
Full story on the link below.In an earlier study, Lee’s group noted that many young female athletes reported using oral contraception. These pills have been specifically formulated to alter a woman’s steroid-hormone levels. Since certain steroids can affect how efficiently the body bulks up and gains muscle, Lee wondered whether these pills might also limit strength gains.
