IVM With Low Cost Priming, Enhanced Oocyte Recovery, and Delayed Transfer (IVMprt)

October 31, 2019 updated by: Bruce Rose, MD

A Prospective Series of IVF Cases Utilizing in Vitro Maturation (IVM) With Low Cost Priming, Enhanced Oocyte Recovery, and Delayed Embryo Transfer Using a Subsequent Frozen Embryo Transfer Cycle

A protocol was developed to improve pregnancy results after IVM compared to results from studies in the literature. Differences from most published protocols include the use of the Steiner-Tan needle to optimize oocyte environment during oocyte retrieval, use of oral medications and very low doses of FSH, and delayed embryo transfer during subsequent warmed cryo-preserved embryo transfer. Eligible patient have a PCO pattern in their ovaries during transvaginal ultrasound.

Detailed Description

All participants are candidates for IVF having PCOS or having PCO patterns in their ovaries who wish to undertake IVM for the potential advantages that it holds. All cycles are proceeded by oral contraceptive use for cycle scheduling purposes. Priming is done with oral letrozole with the addition of 25-75 IU daily starting after 2 days of letrozole. HCG is given when several follicle have diameters 8 mm or greater and no follicles have diameters greater than 13 mm. Oocyte retrieval is done approximately 38 hours later. A Steiner-Tan needle is used for oocyte retrieval in a manner that minimizes the amount of time that an oocyte is out of the ovary and not in a controlled laboratory environment. Oocytes are assessed for maturity for up to 48 hours post retrieval. If mature, oocytes are injected with sperm using ICSI. Embryos are grown to blastocysts and all blastocyst are vitrified. Warmed cryo-preserved blastocyst are transferred using routine IVF protocols during a subsequent cycle.

  • Interventional Model: SINGLE_GROUP
  • Masking: NONE

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
EXPERIMENTAL: All
Patients requiring IVF treatment with PCOS or a PCO pattern in their ovaries who wish to undertake IVM (as a variant of their IVF procedure)
Immature oocytes (rather than mature oocytes) are harvested as in IVF. These oocytes are allowed to mature in the laboratory before fertilization
