Study summary

A single center, prospective, open-label, non-inferiority randomized controlled clinical trials (1:1 treatment ratio) regarding pregnancy outcomes between IVM and standard IVF among infertility couples with PCOS in China.

Read the detailed description

A single center, randomized controlled clinical trial will enroll 350 couples with PCOS undergoing their first cycle of IVF. The participation in this study will be approximately 2 years with a total of 7 visits from the cycle beginning, pregnancy to delivery. On day 2 or day 3 following the onset of menstrual bleeding, eligible patients will be allocated to two groups at a ratio of 1:1- IVM protocol, and standard IVF protocol. All participants will be randomized through stratified block randomization according to the study sites.

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Study arms

  • Active comparator
    standard IVF

    On the Day2/3 of the menstrual cycle, qualified participants will be randomized into either of two groups. Participants in group A will receive standard IVF procedure. Other standard assisted reproductive treatments are similar and parallel between two groups.

    Procedure: standard IVF

  • Active comparator
    In vitro maturation

    On the Day2/3 of the menstrual cycle, qualified participants will be randomized into either of two groups. Participants in group B will receive IVM procedure.Other standard assisted reproductive treatments are similar and parallel between two groups.

    Drug: In vitro maturation

Interventions

  • Procedurestandard IVF

    Ovarian stimulation will be performed by a standard protocol using gonadotrophin-releasing hormone antagonist (GnRH-ant) in association with recombinant FSH (rFSH) and human chorionic gonadotrophin (hCG).Oocyte retrieval is scheduled for 36 (±2) after hCG injection.The retrieved cumulus oocyte complexes (COC) will be inseminated using ICSI or conventional IVF according to the seman analysis. All embryos will be cultured to blastocyst stage and be vitrified.

  • Controlled ovarian stimulation protocol will not performed in this group patients. Transvaginal ultrasound scanning was examined on natural cycle to monitor the follicle size in group B participants. Oocyte retrieval was scheduled once the endometrium had reached at least 6 mm in thickness and there was no follicle larger than 10 mm. After oocyte retrieval, the COCs will be cultured for 28-32h in special IVM media in order to get the matured oocytes. All the metaphase II (MII) oocytes were inseminated by means of intracytoplasmic sperm injection (ICSI). All embryos will be cultured to blastocyst stage and be vitrified.

    Also known as: IVM

What researchers measure

Primary outcomes

  1. the proportion of ongoing pregnancy leading to live birth

    number of ongoing pregnancy leading to live birth resulting from the first oocyte retrieval cycle after the randomization ( 6 month) divided by the number of patients with oocyte retrieval

    Time frame: after 22 weeks of gestation

Secondary outcomes

  1. implantation

    Number of gestational sacs observed per embryo transferred

    Time frame: 28 days after embryo transfer

  2. clinical pregnancy

    one or more observed gestational sac or definitive clinical signs of pregnancy under ultrasonography at 7 weeks after embryo transfer (including clinical documented ectopic pregnancy)

    Time frame: 7 weeks after embryo transfer

  3. Miscarriage

    Spontaneous loss of an intra-uterine pregnancy prior to 28 completed weeks of gestational age

    Time frame: 28 weeks of gestation

  4. Preterm birth

    Birth of a fetus delieved after 28 and before 37 completed weeks of gestational age in participants confirmed ongoing pregnancy

    Time frame: 28-37 weeks of pregnancy

  5. Birth weight

    Including low birth weight (defined as weight \<2500 gm at birth), very low birth weight (defined as \< 1500 gm at birth), high birth weight (defined as \> 4000 gm at birth) and very high birth weight (defined as \> 4500 gm at birth).

    Time frame: within 2 weeks after live birth

  6. Large for gestational age

    Birth weight \>90th centile for gestation, based on standardised ethnicity based charts.

    Time frame: within 2 weeks after live birth

  7. Small for gestational age

    Less than 10th centile for gestational age at delivery based on standardised ethnicity based charts.

    Time frame: within 2 weeks after live birth

  8. Congenital anomaly

    Any congenital anomaly will be included diagnosed by physical examinition, ultrasound or necessary testing (including CT, X-ray etc.)

    Time frame: within 2 weeks after live birth

  9. Perinatal mortality

    Fetal or neonatal death occurring during late pregnancy (at 28 completed weeks of gestational age and later), during childbirth, or up to seven completed days after birth.

    Time frame: within 2 weeks after live birth

  10. Moderate/severe ovarian hyperstimulation syndrome (OHSS)

    exaggerated systemic response to ovarian stimulation characterized by a wide spectrum of clinical and laboratory manifestations. It is classified as mild, moderate, or severe according to the degree of abdominal distention, ovarian enlargement and respiratory hemodynamic, and metabolic complications. Diagosised by ultrasound, blood testing and physical examination according the Chinese Medical Guildline.

    Time frame: From date of controlled ovarian hyperstimulation until the date of oocyte retrieval, assesses about 14-16 days.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Mar 2018 (actual). Primary completion is estimated for Jun 2020, 27 months after the start.

Of 203 non-industry interventional studies with no phase under Polycystic Ovary Syndrome, half reached primary completion within 18 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 37. This study's planned 27 months is above that.

Counting every sponsor, half of 218 studies reached it within 18 months; a quarter within 7 and three quarters within 37.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 29, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
