ABSTRACT
OBJECTIVE:
To investigate flexibility in starting controlled ovarian stimulation at any phase of the menstrual cycle in infertile women undergoing treatment with assisted reproduction.DESIGN:
Retrospective cohort study.SETTING:
Academic tertiary-care medical center. PATIENT(S) At total of 150 infertile patients undergoing in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) treatment. Ninety of the women also underwent frozen embryo transfer (FET) procedures. INTERVENTION(S) Depending on the phase of the menstrual cycle when ovarian stimulation was started, three groups of patients were identified, namely conventional group (ovarian stimulation started in the early follicular phase), late follicular phase group, and luteal phase group. When dominant follicles were observed, final oocyte maturation was triggered with the use of GnRH agonist and hCG. In all three groups, viable embryos were cryopreserved for subsequent transfer. PRIMARYOUTCOME:
number of mature oocytes retrieved. SECONDARYOUTCOMES:
fertilization rate, viable embryo rate per oocyte retrieved, cancellation rate, and clinical pregnancy outcomes from FET cycles. RESULTS(S) There were no differences in the mean number of mature oocytes retrieved in the conventional group, late follicular phase group, and luteal phase group (5.7 ± 3.6, 5.2 ± 3.7, and 5.2 ± 3.9, respectively). Similarly, no significant differences were observed in the viable embryo rate per oocyte retrieved (37.9%, 38.5%, and 43.6%), clinical pregnancy rates (41.5%, 45.5%, and 38.9%), and implantation rates (30.7%, 30.2%, and 27.1%) in the three groups. CONCLUSION(S) All three ovarian stimulation protocols were observed to be equally effective. These results demonstrate that ovarian stimulation can be commenced on any day of the menstrual cycle.
