The Analysis of Infectious Chronic Endometriosis (ALICE) is a test that helps evaluate pathogenic bacteria in a woman’s endometrial environment

A successful embryo implantation depends on the health of the endometrium (the lining of the womb). Pathogenic bacteria that can cause chronic endometriosis are linked to implantation failure and recurrent miscarriages.

ALICE (Analysis of Infectious Chronic Endometriosis) is a diagnostic test that detects pathogenic bacteria and can recommend appropriate probiotic or antibiotic treatment, and thereby improve their chances of conceiving.


ALICE tests require only a small endometrial tissue that can be taken at the clinic. It involves a small procedure, which requires no sedation. The sample will then be analysed using the latest Next Generation Sequencing (NGS) technology to provide a complete profile of the bacteria present in the tissue. EMMA includes the ALICE test that detects the bacteria causing chronic endometriosis.

Who is the ALICE test recommended for?

ALICE test is beneficial for any patient looking to conceive, as it provides insights into the microbiological environment that the embryo will encounter during implantation. The test is also recommended to patients with repeated implantation failure or recurrent miscarriages to identify if chronic endometritis is an underlying condition and a cause for their fertility problems.
