Title: A Multicentre Randomized Controlled Trial of a "Freeze All and Transfer Later" Versus a Conventional "Fresh Embryo Transfer" Strategy for Assisted Reproductive Technology (ART) in Women With a Regular Menstrual Cycle
Brief Summary: The purpose of this study is to compare conventional fresh embryo transfer with a "freeze all and transfer later strategy" in assisted reproductive technology in terms of ongoing pregnancy rates, live birth rates as well as perinatal outcomes.


Options:
A: Inclusion Criteria:

* Women \[18 - 40\[years of age (according to date of birth at time of informed consent) who are eligible for ovarian stimulation and ART treatment, including intracytoplasmic sperm injection (ICSI)
* Absence of anatomical abnormalities of the reproductive tract that would interfere with implantation or pregnancy
* Absence of any medical condition in which pregnancy is contraindicated
* Motile, ejaculatory sperm must be available (donated and/or cryopreserved sperm is allowed). Intracytoplasmic sperm injection (ICSI) will be allowed during this trial

* Not to participate in another IVF study at the same time

Exclusion Criteria:

* women with polycystic ovary syndrome

* ≤ 40 years
* ≥ 4 diploid embryos (i.e. having 2 PNs)
* ≤ 3 Prior ART cycles (IVF, ICSI and related procedures)
* All 2PN embryos (for all 3 arms) must be imaged by Eeva
