The investigators secondarily hypothesize that ex vivo HIV replication will be less suppressed in cervical tissue and cervicovaginal fluid when women are using the co-formulated pre-exposure prophylaxis oral pill containing tenofovir disoproxil fumarate (TDF), the prodrug of tenofovir, and FTC concurrently with the contraceptive injection DMPA as compared to when they are on TDF/FTC alone. This study is a biphasic steady state pharmacokinetic and pharmacodynamic study of TFV and FTC in healthy women comparing the drug levels and activity in the absence (first phase) and then the presence (second phase) of DMPA. The investigators will recruit 12 healthy women aged 18-45 who are HIV-negative and at low risk for acquiring HIV. Participants will take TDF/FTC for 14 days, after which drug levels will be measured and DMPA administered. After at least a 2 week washout period for TDF/FTC, participants will again take TDF/FTC for 14 days, and drug levels will be measured again. HIV replication activity will also be measured in cervicovaginal fluid and cervical tissue at baseline before starting TDF/FTC, after 14 days of TDF/FTC, and then after the second 14 days of TDF/FTC in the presence of DMPA.'}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['ADULT'], 'maximumAge': '45 Years', 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Women aged 18-45 at screening\n* In general good health and without any clinically significant systemic disease by history and per investigator judgement\n* HIV negative at screening\n* Heterosexually abstinent, consistent use of condoms, or female or male partner sterilization\n* Currently having regular menstrual cycles (defined as cycles lasting 21-35 days by participant report)\n* Agree not to participate in any other clinical trials involving drugs or medical devices during the study period\n* Willing to comply with the study protocol\n\nExclusion Criteria:\n\n* Currently or recently pregnant or breastfeeding (defined as pregnancy or breastfeeding in the last 3 months)\n* Desiring pregnancy in the next 9 months\n* Use of copper intrauterine device or other method of hormonal contraception\n* Status post hysterectomy and/or bilateral oophorectomy\n* Positive test for Hepatitis B surface antigen at screening\n* Positive for Neisseria gonorrhea, Chlamydia trachomatis, or Trichomonas vaginalis at screening\n* Positive syphilis screening test at screening\n* Symptomatic bacterial vaginosis, defined as vaginal symptoms with Nugent score ≥ 7.
