Clinical Studies Using Pre-seed?

BunBun

Hi ladies. I’ve been TTC for 9 months and no luck. Thinking about trying Pre-Seed in my next cycle but I want to see if there have been any clinical studies done on it. I’ve heard so MANY stories of how using Pre-Seed have led to miscarriages. Not sure if it’s coincidence or a correlation. Not sure if it’s capturing sperm that are just bad. Thoughts?
