- Scientific TitleComparing in vitro maturation of oocytes with in vitro fertilisation in women with an increased risk of ovarian hyperstimulation syndrome: A multicentre randomised controlled trial with non-randomised pilot study.
- hypothesisA randomized controlled trial to compare the following strategies: two IVM-ICSI cycles or one COH-IVF/ICSI cycle. These strategies are expected to have comparable outcomes for ongoing pregnancy rates and direct costs (treatment costs). IVM is expected to have favourable outcomes for indirect costs (less complications) and quality of life scores.
Our hypothesis is the non-inferiority of the IVM-ICSI strategy to the COH-IVF or COH-ICSI strategy.
- Healt Condition(s) or Problem(s) studiedInfertility, Polycystic ovary syndrome (PCOS), OHSS
- Inclusion criteria1. Women with PCOS according to the Rotterdam Criteria (The Rotterdam ESHRE/ASRM-Sponsored PCOS consensus workshop group, 2004) which not did achieve an ongoing pregnancy after ovulation induction (with clomiphene citrate or LEO and rFSH);
2. Women with an IVF or ICSI indication and increased risk for developing OHSS (history of OHSS or cycle cancellation for imminent OHSS).
- Exclusion criteria1. Woman or partner younger than 18 years and woman older than 38 years;
2. Unable to speak or read the Dutch language;
3. Medical contraindication for pregnancy or childbirth;
4. Positive serology for Hepatitis B, C or HIV;
5. Diminished ovarian reserve: early follicular serum FSH > 10 IU/l and/or poor response during earlier COH/IVF or COH/ICSI with ³ 150 IU rFSH/day;
6. Persisting ovarian cysts > 30 mm diameter.

- Brief summaryCurrent artificial reproductive techniques (ART) as in vitro fertilisation (IVF) and intracytoplasmatic sperm injection (ICSI) require controlled ovarian hyperstimulation (COH) to increase the number of available mature oocytes. COH can lead to ovarian hyperstimulation syndrome (OHSS), a potentially life-threatening complication.
In in vitro maturation (IVM) immature oocytes are harvested from the ovaries without COH and matured in vitro in approximately 30 hours. Subsequently, these in vitro matured oocytes can be fertilised by IVF or ICSI. Due to the absence of COH, IVM has especially potential for patients with an increased risk of developing OHSS, such as polycystic ovary syndrome (PCOS)-patients. Further benefits of IVM extend to a reduction of treatment burden and reduced costs.
We propose a study to evaluate the effectiveness of IVM/ICSI.
In this multicenter randomised clinical trial we will compare two IVM/ICSI cycles versus one conventional IVF/ICSI cycle in a period of three months.
The trial will be preceded by a pilot study of 50 non-randomised IVM cycles. A total of 450 patients will be included. The primary endpoint will be ongoing pregancy rate. Secondary endpoints will be live birth rate, multiple pregnancy rate, clinical pregnancy rate, embryo quality, occurrence of adverse events as OHSS, patients’ quality of life and costs per livebirth.
