Beskrivelse
Inclusion Criteria:
- Signed Informed Consent Form to participate in this study voluntarily.
- Age 18-37 years at the time of starting the CAPA-IVM cycle.
- Body mass index (BMI) ≤38 kg/m2.
- Serum AMH levels greater than or equal to 3.5 ng/mL.
- Have an indication for IVM/IVF cycle.
- Have not received more than two previous treatments of IVM/IVF.
- Willing and able to comply with trial procedures, including oocyte pick-up from small follicles and to follow a CAPA-IVM cycle.
- Agree to culture all embryos to blastocyst stage, vitrify suitable blastocysts, and submit suitable blastocysts for PGT-A according to clinic protocol before determining transfer eligibility.
- Agree that only euploid CAPA-IVM-derived blastocysts will be eligible for transfer and that a single euploid blastocyst will be transferred per programmed FET cycle, unless a protocol-defined exception is prospectively justified by the investigator.
Exclusion Criteria:
- Prior ovarian surgery.
- Known uterine abnormalities (adenomyosis, leiomyoma (≥5 cm), bicornuate uterus, intrauterine adhesion) that would compromise successful pregnancy or live birth.
- Had received ovarian stimulation within the last 3 months for ovulation induction or IVF
- Had evidence of a very low oocyte maturation rate (oocyte maturation rate < 50% in any previous IVF or IVM cycle).
- For male partners: severe oligoasthenoteratozoospermia, requirement for retrograde ejaculation procedures or surgical sperm retrievals. Donor sperm is permitted.
- Known chromosomal abnormalities in participant or partner.
- Have herself or partner with acute urinary tract infection or sexually transmitted diseases.
- Have herself or partner a severe mental disorder, such as schizophrenia, bipolar affective disorder, or intellectual disability caused by mental disorders.
- Have a history of recurrent pregnancy loss defined as two or more clinical pregnancies without live birth.
- Known tumors of the ovary, breast, uterus, adrenal gland, pituitary or hypothalamus that would preclude to conduct a CAPA-IVM cycle without ovarian stimulation or participation in this study.
- Any known clinically significant systemic disease (heart, liver, kidney or other organs) that would prevent or compromise pregnancy or participation in this study.
- Pregnancy or contraindication to pregnancy.
- Undiagnosed vaginal bleeding.
- Known drug or alcohol abuse or dependency for the participant or partner for the last 12 months.
- Current or past (3 months) smoking habit of 10 or more cigarettes per day.
- Had a recent exposure to teratogenic radiation, drugs or toxins which could still be active during the study period.
- Currently participating in another clinical trial or receiving an investigational medicinal product.
- Previous participation in this study.

Eksperimentel: CAPA-IVM
Patients will undergo egg retrieval prior to in vitro maturation with CAPA-IVM system and subsequent frozen embryo transfer.
|
CAPA-IVM is a two-step IVM process to mature oocytes in the laboratory after egg retrieval.

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Metaphase II rate
Tidsramme: Assessed approximately 40 hours after egg retrieval
|
The metaphase II (MII) rate is defined as the number of oocytes that reach MII stage of development divided by the number of cumulus-oocyte-complexes (COCs) placed into CAPA-IVM culture.
|
Assessed approximately 40 hours after egg retrieval
