Dear Dr. Sher,

Thank you for the detailed article on immunological issues of embryo implantation failures.
I’m writing to you as a fertility patient in France. After a certain number of blastocysts transfered with a single implantation and early miscarriage, i’ve been adviced to undergo a MatriceLab test which measured uterine receptivity.
The result stated i had uNK cells immaturity.
French fertility specialists are devided as for the accuracy and validity of this test.
I would like to know your opinion on it: do their clinical tests and outcomes seem relevant? And the frozen embryo transfer protocols proposed?

Thank you very much in advance,
Best regards,
Manon
