Exclusion Criteria:
- History of inflammatory bowel disease or other inflammatory, infiltrative, infectious or vascular condition involving the lower gastrointestinal tract that, in the judgment of the investigators, may be worsened by study procedures or may significantly distort the anatomy of the distal large bowel

Any known medical condition that, in the judgment of the investigators, increases the risk of local or systemic complications of endoscopic procedures or pelvic examination, including but not limited to:
- Uncontrolled or severe cardiac arrhythmia
- Recent major abdominal, cardiothoracic, or neurological surgery
- History of uncontrolled bleeding diathesis
- History of colonic, rectal, or vaginal perforation, fistula, or malignancy
- History or evidence on clinical examination of ulcerative, suppurative, or proliferative lesions of the anorectal mucosa, or untreated sexually transmitted disease with mucosal involvement
Continued need for, or use during the 14 days prior to enrollment, of the following medications:
- Aspirin or more than 4 doses of NSAIDs
- Warfarin, heparin (low-molecular weight or unfractionated), platelet aggregation inhibitors, or fibrinolytic agents
- Any form of rectally administered agent besides lubricants or douching used for sexual intercourse
Continued need for, or use during the 90 days prior to enrollment, of the following medications:
- Systemic immunomodulatory agents
- Supraphysiologic doses of steroids
- Experimental medications, vaccines, or biologicals
- Intent to use HIV antiretroviral pre/post-exposure prophylaxis (PrEP or PEP) during the study, outside of the study procedures
- Symptoms of an untreated rectal sexually transmitted infection (e.g. rectal pain, discharge, bleeding, etc.)
- Current use of hormonal therapy
- Any other clinical condition or prior therapy that, in the opinion of the investigator, would make the patient unsuitable for the study or unable to comply with the study requirements.
