5. History of gonorrhea or chlamydia within 12 months prior to screening.
6. Travel or sexual partner travel to regions or countries where Ebola or Zika outbreaks occurred in the past 12 months.
7. Any other medical, travel, or behavioral history that deems donors of human cells, tissues, and cellular and tissue-based products (HCT/Ps) ineligible.

12. IUD insertion or removal, cervical cryotherapy, or cervical laser treatment within 2 months prior to screening.
13. Any condition requiring regular periodic use of systemic antibiotics during the study.
14. New use of long-acting hormonal treatments. Participant may be enrolled if stable (>3 months) or existing therapy as determined by the investigator.
15. Any social, medical, or psychiatric condition, including history of drug or alcohol abuse that in the opinion of the investigator would make it unlikely for the participant to comply with the study or would complicate interpretation of data from her participation.
16. Menopause defined as more than 12 consecutive months of amenorrhea without another known cause.
17. Irregular menstrual cycles that preclude scheduling appointments to avoid menstruation.
18. Donors will be screened for cytomegalovirus (CMV), Rubella, and Varicella Zoster Virus (VZV) IgG, which will not be a criterion for exclusion, but samples from CMV positive and/or Rubella positive and/or VZV positive Donors will only be matched with CMV positive and/or Rubella and/or VZV positive Recipients.
19. Abnormal finding on exam, which, in the opinion of the investigator, precludes participation.
20. Sexual history or current sexual behavior, or having sexual partners that engage in such behaviors, which introduces increased risk of sexually transmitted infections or exposure to pathogenic organisms.
