EnMotion, Embryo's Natural Motion

The proposed research design is a prospective randomized control trial. Patients with normal
ovarian reserve, who would be expected to have reasonable outcomes after in vitro
fertilization, will serve as the subjects. Embryos from the same patient will be randomized
to either static or dynamic culture. They will then be cultured to the blastocyst stage of
embryo development and biopsied for preimplantation genetic screening. The best chromosomally
normal embryo from each culture group will be selected and transferred to complete a double
embryo transfer in a subsequent frozen embryo transfer cycle the following month.

Inclusion Criteria:

- Infertile women seeking in vitro fertilization treatment with aneuploidy screening

- Patient is eligible for a two-embryo transfer in compliance with ASRM guidelines

- Patient able to undergo a frozen embryo transfer cycle the month following the vaginal
oocyte retrieval procedure

- Maximum day 3 Follicle-stimulating hormone level (≤12 IU/L)

- Anti-mullerian hormone level ≥ 1.2g/mL, tested within previous year

- ≤1 prior failed IVF cycle

- Male partner with >100,000 total motile spermatozoa per ejaculate (donor sperm
acceptable)

- Body Mass Index ≤ 32

- Antral Follicle Count ≥ 8

Exclusion Criteria:

- Diagnosis of endometrial insufficiency defined as a prior cycle with maximal
endometrial thickness ≤ 6mm, abnormal endometrial pattern (failure to attain a
trilaminar appearance), persistent endometrial fluid

- Use of oocyte donation

- Use of gestational carrier

- Medical contraindication to double embryo transfer

- Use of testicular aspiration or biopsy procedures to obtain sperm

- Presence of a hydrosalpinx that communicates with the endometrial cavity

- Any contraindications to undergoing in vitro fertilization or gonadotropin stimulation

- Single gene disorder requiring more detailed embryo genetic analysis
