This is a brand new study that discusses an interesting topic of the use of contraceptives and the effect on muscle hypertrophy and strength. What they found is that the group taking the oral contraceptives had more muscle hypertrophy than the group that did not take the oral contraceptives. Another interesting takeaway is that the testing group, although experienced hypertrophy, did not receive any additional strength differences from the control group. There are definitely limitations to this study such as a small sample size and the fact they only trained the lower body. There needs to be more research around this topic as there are many different kinds of oral contraceptives so at this point there cannot be a generalized statement about how oral contraceptives effect strength gains and muscle size.
