A few things:
The lawyers struggled to put forth the scientific arguments. This was partly because they were not highly skilled lawyers, this was partly due to the fact that the case was hard to prove because sexual dysfunction is not a well understood in general, and lastly because more scientific research would have been helpful. With more competent lawyers, they might have been able to pull it off but that’s not what happened.
There is a lot of strength in numbers in mass tort litigation and it will be hard to put forth the same number of plaintiffs at this point. I really can’t overstate this point. Still, this obstacle isn’t a guarantee that it is impossible. There are no US lawyers I know of that are willing to take this on at this point.
You might have more luck in the EU because the system is more protective of consumers over corporations. I don’t know where you live.
You are right, the Reuters article shows that Merck hid information from the public. That is necessary, but not sufficient, to successfully win against Merck at least in the US.
The whole process is really emotionally painful. You may not want to do it, especially with what I believe is a limited chance of getting traction let alone success. But that’s up to you.
I’m sorry to be the bearer of pessimistic news but I think realistic expectations are important to have in the healing process, at least from the mental abuse we’ve been dealt in this situation.
