Does pineapple core help with implantation ?

I have read that pineapple contains bromelain.

" Bromelain is a proteolytic enzyme that breaks up proteins that inhibit embryo implantation. Consuming a whole pineapple (focusing on the core as it has the highest concentration of Bromelain) during a fertility cycle can be beneficial."

Please let me know, has this been proven scientifically?

Are there any research studies regarding pineapple influencing implantation?

Thanks a lot,
