Title: Live Birth After Fresh Embryo Transfer vs Elective Embryo Cryopreservation/Frozen Embryo Transfer in Women With Polycystic Ovary Syndrome Undergoing IVF: A Multi-center Prospective Randomized Clinical Trial
Brief Summary: Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders in women of childbearing age. However, the optimal infertility treatment for PCOS patients is still a matter of controversy. Despite producing more follicles and more oocytes than other women undergoing controlled ovarian hyperstimulation during an IVF cycle, women with PCOS have comparable or lower pregnancy rates. Additionally women with PCOS patients undergoing IVF have a higher risk of developing ovarian hyperstimulation syndrome (OHSS), which may be aggravated by pregnancy after an embryo transfer in a fresh cycle. Further women with PCOS are thought to have higher rates of later pregnancy complications including spontaneous abortion, pre-eclampsia, and preterm labor that may be related to impaired implantation in the superovulated endometrium. We propose a randomized clinical trial of elective embryo cryopreservation followed by a programmed cycle of endometrial preparation and frozen embryo transfer (FET) compared to fresh embryo transfer in women with PCOS undergoing in vitro fertilization (IVF).


Options:
A: Inclusion Criteria:

* 1st, 2nd or 3rd cycle of PGD in which embryo transfer was performed
* Indications for PGD: monogenic indications and X-linked disorders with a 25-50% risk of transmission and that are not associated with reduced ovarian response
* Normal ultrasound scan, i.e. presence of both ovaries, without evidence of abnormality within 6 months prior to randomisation.
* Regular menstrual cycles of 21-35 days, presumed to be ovulatory.

Exclusion Criteria:

* POLYCYSTIC OVARIAN SYNDROME (Rotterdam criteria \*)

  \* At least two of the following three features: (i) Oligo- and/or anovulation (ii) Clinical and/or biochemical signs of hyperandrogenism (iii) Polycystic ovaries and exclusion of other aetiologies (congenital adrenal hyperplasias, androgen-secreting tumours, Cushing's syndrome)
* Poor responders (Bologna criteria \*\*)

  \* \* At least two of the following three features: (i) Advanced maternal age (≥40 years) or any other risk factor for poor ovarian response (POR); (ii) A previous POR (≤3 oocytes with a conventional stimulation protocol); (iii) An abnormal ovarian reserve test (i.e. antral follicle count (AFC) 5-7 follicles, or anti-Mullerian hormone (AMH) 0.5-1.1 ng/ml).
* Endocrine or metabolic abnormalities (pituitary, adrenal, pancreas, liver or kidney)
* anticipated high response: AMH \>5.0 ng/ml or AFC \>20
* Endometriosis ≥ grade 3
* Age \> 40 years and 364 days
B: Inclusion Criteria:

* Women who have at least one of the following indications for IVF or ICSI:

  1. Ovulation dysfunction and failed to become pregnant from ovulation induction treatment;
  2. Tubal factors: unilateral or bilateral tubal obstruction, adhesion, unilateral or bilateral Salpingectomy or tubal ligation;
  3. Male factors: oligoasthenozoospermia, obstructive azoospermia;
* Women who are undergoing their first cycle of IVF or ICSI;
* Women who retrieved oocytes number \> 3;
* Women who are capable of giving informed consent.

Exclusion Criteria:

* Women who underwent unilateral ovariectomy;
* Women diagnosed as uterus abnormality: malformed uterus (uterus unicorns, septate uterus, duplex uterus, uterus bicomis), adenomyosis, submucous myoma, intrauterine adhesion;
* Women or their partner with abnormal chromosome karyotype including chromosome polymorphism;
* Women who have experienced recurrent spontaneous abortion (including biochemical pregnancy abortion) more than 2 times;
* Women with medical condition that represent contraindication to assisted reproductive technology and/or pregnancy;
* Women who has developed severe OHSS before oocyte pick-up day;
* Women with retrieved oocytes number ≤3;
