- Users of any hormonal or non-hormonal intrauterine device (IUD).
- Participants who have HIV/AIDS or other immunodeficiency.
- Participants who test positive at screening for HIV, chlamydia, gonorrhoea, Mycoplasma

they receive successful treatment at their own medical provider.
- Participants who have received treatment involving experimental drugs less than 30
days prior to this study.
- Participants who have undergone some sort of procedure involving trauma to the cervix
within the last month prior to screening (i.e., IUD removal, cervical cryotherapy, or
cervical laser treatment).
- Participants with any known condition requiring regular use of antibiotics, that would
suggest the participant is likely to require antibiotic treatment during the study.
- Systemic and/or vaginally applied antibiotic use within the last month prior to
screening.
- Participants with new (<3 months) use of long-acting hormonal treatments. Participant
may be enrolled if stable (>3 months) or existing therapy as determined by the
investigator.

investigator would make it unlikely for the participant to comply with the study or
would complicate interpretation of data from her participation.

surgical gynaecological medical history, which, in the opinion of the investigator,
precludes participation.

that could interfere with the collection of endometrial fluid.
