Study Details

Brief summary:

The goal of this clinical trial is to test the effect of granulocyte colony-stimulating factor (G-CSF, A.K.A. Filgrastim) in infertility patients undergoing in vitro fertilization (IVF) treatment. The main question it aims to answer is:

Can in vitro fertilization-embryo transfer (IVF-ET) outcomes be improved by supplementing the transfer media with Granulocyte colony-stimulating factor (GCSF)?

Participants will undergo their embryo transfer as per the normal clinic protocol but will be randomized to either receive the standard embryo transfer media or the GCSG-supplemented transfer media.

Researchers will compare the GCSF and standard transfer media groups to see if clinical outcomes are improved (i.e., implantation rate, pregnancy, clinical pregnancy rate, live birth rate).

Eligibility Criteria

Eligibility Criteria

Sex: Female

Age: 18 - 38

Healthy Volunteers: Not accepted

Inclusion Criteria:

  • Recruited subjects will either be undergoing a fresh IVF-ET cycle in which the embryo(s) generated from the initial treatment cycle are transferred during that same cycle (i.e., on day 5 or 6 post-egg retrieval) or an FET cycle in which the embryo(s) transferred were generated in a previous IVF cycle and were cryopreserved for subsequent warming and transfer.

Exclusion Criteria:

  • Patients with uterine factor or severe male factor infertility will be excluded.
  • Patients who have had previous IVF failures will be excluded.

Interventions and Outcome Measures

Arms

experimental: GCSF-Supplemented Embryo Transfer Media

Intervention Group Frozen Embryo Transfers: Cryopreserved embryos will be thawed according to the Kitazato thawing protocol and will be subsequently transferred to a center-well dish containing 1 mL of embryo transfer media supplemented with GCSF. The embryos will be cultured in this medium for approximately 3 hours before the embryo transfer (ET) procedure. During the ET procedure, the same media will be used to fill the ET syringe and catheter that will be used to deposit the embryos into the uterus by the physician.

Fresh Embryo Transfers: On day 5 or 6 of culture, viable embryos will be transferred into a center-well dish containing 1 mL of embryo transfer media supplemented with GCSF. The embryos will be cultured in this medium for approximately 3 hours before the ET procedure. During the ET procedure, the same media will be used to fill the ET syringe and catheter that will be used to deposit the embryos into the uterus by the physician.

placebo comparator: Standard Embryo Transfer Media

Control Group Fresh Embryo Transfers: On day 5 or 6 of culture, viable embryos will be transferred into a center-well dish containing 1 mL of standard embryo transfer media. The embryos will be cultured in this medium for approximately 3 hours before the embryo transfer (ET) procedure. During the ET procedure, the same media will be used to fill the ET syringe and catheter that will be used to deposit the embryos into the uterus by the physician.
