Evaluation of the Alife Hera System as an Adjunctive Tool for the Prioritization of Embryos Deemed Suitable for Transfer

To evaluate the clinical pregnancy rate (pregnancy defined as fetal heartbeat at 6-8 weeks) with the adjunctive use of the Hera System (Hera System used with traditional morphological grading) with embryos already deemed suitable for transfer compared to trained embryologists using standard morphology criteria alone.

About this study

To evaluate the clinical pregnancy rate (pregnancy defined as fetal heartbeat at 6-8 weeks) with the adjunctive use of the Hera System (Hera System used with traditional morphological grading) with embryos already deemed suitable for transfer compared to trained embryologists using standard morphology criteria alone.

To evaluate the performance and utilization of the Hera System as an adjunctive embryo grading and prioritization tool in an embryology lab setting with trained embryologists.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • >21 and < 43 years of age
  • Women undergoing in vitro fertilization treatment using their own eggs
  • At least 8 eggs retrieved
  • Fertilization using only ejaculated sperm including donor sperm (fresh or frozen)
  • Single embryo transfer (SET)
  • Willing to comply with study protocol and procedures and be able to speak English
  • Willing to provide written informed consent

Exclusion criteria

  • Gestational carriers
  • Use of re-inseminated eggs
  • Use of donor eggs
  • History of cancer
  • Fertilization using surgically removed sperm
  • Transfer of multiple (more than one) embryos at once
  • Participants undergoing IVF with intent to bank embryos (i.e. no intention of embryo transfer for at least 6 months following egg retrieval)
  • Concurrent participation in another clinical study that might interfere with the study results in either study

Treatment and study plan

Hera Score

Device

The device uses patient metadata (patient age, day of image capture) and a software algorithm to analyze features of the blastocyst morphology to provide adjunctive information that may predict further development of the embryo to clinical pregnancy after embryo transfer.

Primary outcomes

  1. Primary Endpoint

    Time frame: up to 8 weeks

    The primary study endpoint is clinical pregnancy - defined as a fetal heartbeat at 6-8 weeks.

Secondary outcomes

  1. Incidence of disagreement

    Time frame: week 1

    Incidence of disagreement for the top-ranked embryo between the Hera System and the embryologist.

  2. User Experience

    Time frame: through study completion at 8 weeks

    Assessment of Hera System usability as reported by the embryologist using a user questionnaire.
