No Intervention: Prophylactic antibiotics
Current standard of care in our practice for a fresh in vitro fertilization cycle is to administer one dose of 1 gram oral azithromycin on day one of the IVF cycle start to both the male and female partner. In cases of same-sex couples, only the female undergoing the embryo transfer receives prophylaxis. This will serve as our control arm entitled: prophylactic antibiotics.
Experimental: No antibiotic prophylaxis.
Couples randomized to the no-antibiotic treatment group will not be prescribed oral antibiotic prophylaxis.
Other: Withholding antibiotic prophylaxis
Our intervention will be a deviation from our current standard of care which is universal antibiotic prophylaxis, even in low risk populations. Our intervention will be withholding antibiotic prophylaxis in low risk populations.
- Clinical pregnancy rate [ Time Frame: Our primary outcome measure will be obtained at 5-8 weeks gestational age following embryo transfer ]Defined as a gestational sac, with fetal pole and cardiac activity, on ultrasound
- Miscarriage rate [ Time Frame: Prior to 20 weeks gestation in a previously established clinical pregnancy ]Pregnancy loss per clinical pregnancy before 20 weeks
- Embryo development [ Time Frame: Intraoperative (This outcome measure will be assessed from the time of egg retrieval to embryo transfer or embryo cryopreservation) ]As evaluated by fertilization rate (number of two-pronuclei embryos per mature oocyte), blastocyst conversion rate (number of day 5 embryos from two-pronuclei embryos), and blastocyst utilization rate (number of day 5 embryos transferred or frozen per two-pronuclei embryos).
- Live birth [ Time Frame: delivery ]Number of live births per embryo transfer
- Reproductive Tract Microbiome [ Time Frame: Approximately 30 days from start of IVF cycle ]Swabs will be obtained across the IVF cycle to evaluate changes in the reproductive tract microbiome
- Reproductive Tract Virome [ Time Frame: Intraoperative (At the time of embryo transfer) ]Swabs will be obtained at the time of embryo transfer to evaluate the virome
