- Detailed Description
IVM (in vitro maturation) has been proved to be a more friendly treatment protocol for PCOS (polycystic ovary syndrome) patients compared with conventional controlled ovarian stimulation, with less complications (especially ovarian hyperstimulation syndrome), shorter treatment duration, lower cost, and acceptable pregnancy outcomes. CAPA (capacitation) IVM without hCG (human chorionic gonadotropin) priming, has routinely been used at My Duc hospital for nearly 3 years to replace hCG-IVM (with hCG priming) because of absolutely synchronized oocyte maturation stage and better embryo results and better pregnancy outcomes. However, with CAPA IVM, embryos are freezed-only and will be transferred in the next cycles. This process will increase the cost of freezing and thawing embryos, and increase the treatment duration, which complicates the IVM procedure and turns IVM into an unfriendly protocol to PCOS patients. Therefore, our group conducts this study to find out the effectiveness of fresh transfer protocol after CAPA IVM compared with freezing-only CAPA IVM protocol. The fresh transfer protocol for CAPA IVM is applied from previous hCG IVM protocol, with the use of hCG and exogenous estradiol and progesterone, but at different timings.

Group Intervention Description CAPA-Freeze-only CAPA-Freeze-only Receiving FSH (Menopur, Ferring) for 2 days on day 2/3 of the menstrual cycle (spontaneous/ OCP administration) and an ultrasound scan will be performed subsequently. Oocytes retrieval will be performed 42 hours after the last injection. Pre-maturation will last for 24-30 hours. ICSI will be used for insemination. Freeze-only on day 3 and frozen embryo transfer will be performed on the subsequent cycle using HRT protocol with a maximum of 2 embryos transferred CAPA-Fresh CAPA-Fresh Receiving FSH (Menopur, Ferring) for 2 days on day 2/3 of the menstrual cycle (spontaneous/ OCP administration) and an ultrasound scan will be performed subsequently. Oocytes retrieval will be performed 42 hours after the last injection. Receiving hCG 5000IU x 2 (10000IU) after Oocytes retrieval. Pre-maturation will last for 24-30 hours. ICSI will be used for insemination. Fresh embryos transfer will be performed on day 3 using HRT protocol with a maximum of 2 embryos transferred.
- Primary Outcome Measures
Name Time Method Ongoing pregnancy resulting in live birth after the first embryo transfer of the started treatment cycle. At 24 weeks of gestation Live birth is defined as the birth of at least one newborn after 24 weeks' gestation that exhibits any sign of life (twin will be a single count).
For the timing of this occur, ongoing pregnancy will be used, conditional on the fact that this ongoing pregnancy results in live birth.
- Secondary Outcome Measures
Name Time Method Positive pregnancy test at 2 weeks after the embryo placement after the completion of the first transfer Serum human chorionic gonadotropin level greater than 5 mIU/mL
Ongoing pregnancy At 12 weeks' gestation Ongoing pregnancy is defined as pregnancy with detectable heart rate at 12 weeks' gestation or beyond, after the completion of the first transfer
Ovarian hyperstimulation syndrome (OHSS) at 03 days after oocytes pick-up and 14 days after embryo transfer Routine assessments for OHSS were performed on day 3 post oocyte retrieval in both groups. At other times, OHSS was evaluated if symptoms were reported by the patient. OHSS was classified using the flow diagram developed by Humaidan and colleagues for use in clinical trial settings
Ectopic pregnancy at 12 weeks of gestation after the completion of the first transfer a pregnancy in which implantation takes place outside the uterine cavity after the completion of the first transfer
Hypertensive disorders of pregnancy at 20 weeks of gestation or beyond after the completion of the first transfer Pregnancy-induced hypertension, pre-eclampsia and eclampsia
Clinical pregnancy 5 weeks after embryo placement after the completion of the first transfer at least one gestational sac on ultrasound at 7 weeks' gestation with the detection of heart beat activity
Implantation rate 3 weeks after embryo transferred after the completion of the first transfer as the number of gestational sacs per number of embryos transferred
Number of embryos on day 3 5 days after oocytes pick-up Number of embryos on day 3
Number of good quality embryo on day 3 5 days after oocytes pick-up good quality embryos are defined followed Istanbul consensus
Multiple pregnancy 5 weeks after embryo placement after the completion of the first transfer Defined as presence of more than one sac at early pregnancy ultrasound (6-8 weeks gestation)
Birth weight at the time of delivery Weight of singletons and twins
Time from randomisation to ongoing pregnancy 12 weeks of gestation after the completion of the first transfer Time from randomization to ongoing pregnancy after the completion
Time from randomisation to live birth At the time of delivery Time from randomization to live birth after the completion
Miscarriage at 24 weeks of gestation after the completion of the first transfer pregnancy loss at \< 24 weeks
Preterm delivery at 24, 28, 32 weeks and 37 weeks of gestation after the completion of the first transfer Multiple definitions, defined as delivery at \<24, \<28, \<32, \<37 completed weeks
Congenital anomaly At birth after the completion of the first transfer Any congenital anomaly will be included
Cost-effectiveness Two year after randomization Including direct and indirect costs; costs related to complications treatment. Cost data will be collected for a supplementary analysis and will be reported in a separated paper.
Gestational diabetes mellitus at 24 weeks of gestation after the completion of the first transfer using a 75g oral glucose tolerance test
