The use of assisted reproduction among women in relationships with other women has increased in the United States over the past decade as a result of increased legal access and social acceptance. Despite this shift, limited studies currently exist to guide optimal fertility care for this growing patient population of women seeking assisted reproduction. In this Commentary, assisted reproduction will be meant to include ovulation induction, intrauterine insemination (IUI), and in vitro fertilization (IVF).

It is unknown whether there are differences in pregnancy and perinatal outcomes between cryopreserved oocytes and cryopreserved embryos.
Methods: This is a retrospective cohort study comparing pregnancy and perinatal outcomes between oocyte and embryo cryopreservation at a university-based fertility center.
Objective: To investigate the feasibility of utilizing low-dose hCG alone to complete follicle maturity in a natural cycle, without the need for antecedent exogenous FSH stimulation.
Design: Case series.
Setting: Academic fertility program.
Purpose: In fresh IVF cycles, embryos reaching the eight-cell stage on day 3 of development are thought to have a higher chance of implantation than those reaching this stage on day 4. To determine whether this difference persists after cryopreservation, we compared pregnancy and implantation rates between frozen embryo transfer (FET) cycles using delayed cleavage-stage embryos (cryopreserved day 4) and normal cleavage-stage embryos (cryopreserved day 3).
Methods: Participants underwent FET between 2008 and 2012 using embryos cryopreserved on either day 3 (n = 76) or day 4 (n = 48), depending on the length of time needed to achieve the eight-cell stage.
Background: To compare luteal phase bleeding and pregnancy outcomes in normogonadotropic patients receiving progesterone vaginal gel (PVG) or intramuscular progesterone (IMP) injections.
Methods: In this retrospective cohort study, data from 270 patients (292 cycles) undergoing day-3 fresh embryo transfer were analyzed. PVG, 90 mg daily (170 cycles) or IMP, 50 mg daily (122 cycles) began at egg retrieval.
