Does St. John's seriously damage sperm? I have been buying it at my local Walmart and taking it for 3 years. If it does is it permanent? What can I do

Here are some... Your question and profile lead me to discern that you seems more on the side of being overcautious for many trivial things in life. If wrong, forgive me; it right, follow what I suggest. Since you had reason to take it for 3 yrs, I would suggest keeping on taking it if male infertility has been not an issue to your life; it yes or if you currently do not need it, you may stop its use. So, tailor..
