Trial Title: Clinical Effectiveness of Frozen Thawed Embryo Transfer Compared to Fresh Embryo Transfer

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: NONE
- Phase: None
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* Women under 42 years of age~* Presence of at least 3 embryos suitable to freeze on day 2 or 3 following fertilisation based on the centre's criteria~* Written informed consent~Exclusion Criteria:~* Women using donor eggs/donor sperm~* Women undergoing preimplantation genetic diagnosis~* Women with abnormal uterine cavity shown on hysterosalpingogram or saline infusion sonogram~* Women with hydrosalpinges shown on scanning and not corrected treated~* Women with excessive ovarian response at risk of ovarian hyperstimulation where elective freeze is already planned~* Women with serum progesterone level on day of human chorionic gonadotrophin\>1.5ng/ml or 5 nmol/L~* Women whose embryos have not survived freeze-thawing in the past~* Fresh transfer is planned e.g. patients with endometriosis or adenomyosis who have received prolonged downregulation~* Only frozen transfer is planned e.g. patients receiving ovarian stimulation regimens which may have adverse impacts on the endometrium

Study Arms:
- Control arm (Type: ACTIVE_COMPARATOR): Women allocated to the control arm will either undergo fresh embryo transfer at cleavage stage or extended culture and transfer at blastocyst stage according to local policy. A maximum of 2 embryos or blastocysts will be replaced according to the standard protocol under transabdominal ultrasound guidance. Luteal phase support is given according to local protocols.
- Intervention arm (Type: ACTIVE_COMPARATOR): Fresh embryo transfer will not be undertaken in this group. Embryos will be frozen by vitrification or slow freezing at cleavage or blastocyst stage according to standard agreed local protocols. Women will be contacted after 4 weeks and arrangements made for frozen embryo transfer.

Based on this trial design, predict the completion outcome and termination type (if applicable).
