Hypocritical " my body my choice " ?

So I seen a post on here about orgon donors , and that some of the women who said that they weren't and won't become a orgon donor were getting bullied and attacked by others . I'm kind of confused on this , because I've seen a couple of the ladies who were attacking someone for not wanting to donate her organs comment on abortion forums pretty much saying " nobody has the right to make you do something with your body that you don't want to " or " not your body not your choice " and how nobody should judge another woman for what they choose to do with there body.  Is it just me or does this seem hypocritical ? Like it's that persons body and choice that they don't want to be an organ donor , just like it's a woman's body and choice to not have to carry a child inside her if she doesn't want to / isn't ready to.  
- I'm honestly just curious about what other woman on here think about this? Is it hypocritical or is it diffrent ? Please comment your view!!
