Objective:

To compare the effectiveness of the vaginal ring and vaginal progesterone capsules in supporting the luteal phase in in vitro fertilization procedures.

Methods:

Retrospective study that evaluated pregnancy outcomes in female recipients of embryos obtained from donation of both gametes by comparing the effectiveness of the vaginal ring and vaginal progesterone capsules in supporting the luteal phase in in vitro fertilization procedures.

Results:

Thirty-eight women used the vaginal ring and 46 applied vaginal capsules as luteal phase support. Similar rates of implantation (36.5% versus 36.9%), clinical pregnancy (52.6% versus 50.0%) and live birth (50.0% versus 45.7%) were found.

Conclusions:

Similar implantation, clinical pregnancy and live birth rates were found with the use of the vaginal ring and vaginal progesterone capsules in the support of the luteal phase in in vitro fertilization procedures. Due to the convenience of its use and adequate pregnancy rates, the progesterone vaginal ring is an important alternative in the support of the luteal phase in in vitro fertilization.
