Hormone-free Antral Retrieval for Viable Embryo Storage & Transfer (HARVEST)
A Prospective Adaptive Pilot Study of Serial Unstimulated Oocyte Retrieval and CAPA-IVM (Capacitation In Vitro Maturation) for Euploid Embryo Accumulation in Women With Robust Ovarian Reserve
This study is testing whether eggs can be collected from small follicles without using the usual ovarian stimulation medications. Participants will have up to three egg retrieval procedures. The eggs collected during each retrieval will be matured in the laboratory using the CAPA-IVM (Capacitation In Vitro Maturation) process, fertilized, grown into embryos, and tested to identify chromosomally normal embryos.
Embryos from the retrievals may be frozen and accumulated. If a suitable embryo is available, one chromosomally normal embryo may be transferred. The study will also monitor safety, hormone levels, follicle development, embryo development, pregnancy results, and how well participants tolerate the study procedures.

Detaillierte Beschreibung
This is a single-arm, prospective, open-label, adaptive pilot study designed to evaluate the feasibility of serial unstimulated transvaginal oocyte retrieval followed by CAPA-IVM (Capacitation In Vitro Maturation) for euploid embryo accumulation in infertility patients with robust ovarian reserve.
Approximately 30 participants will be enrolled. Participants will undergo serial unstimulated transvaginal oocyte retrieval procedures targeting visible 4-9 mm antral follicles. Retrieved cumulus-oocyte complexes will undergo CAPA-IVM (Capacitation In Vitro Maturation), followed by intracytoplasmic sperm injection, blastocyst culture, preimplantation genetic testing for aneuploidy, and embryo vitrification/accumulation. Euploid embryos generated across retrievals will be accumulated for subsequent single euploid embryo transfer according to the protocol and site clinical practice.
The study will be conducted in two stages. Stage 1 will enroll approximately 10 participants using initially defined serial retrieval timing to evaluate feasibility, safety, follicle availability, and retrieval interval optimization. Following review of Stage 1 safety, feasibility, follicle emergence, and endocrine data, Stage 2 will enroll approximately 20 additional participants. Retrieval intervals in Stage 2 may be adjusted if supported by interim findings.
The study will summarize retrieval-specific and participant-level outcomes, including follicle counts, oocyte yield, oocyte maturation, fertilization, blastocyst development, PGT-A (Preimplantation Genetic Testing for Aneuploidy) results, euploid embryo yield, embryo accumulation, and progression to single euploid embryo transfer. Safety and tolerability will be assessed throughout the study, including procedure-related complications, anesthesia/sedation-related events, antibiotic-related reactions, retrieval deferrals or discontinuations, and other adverse events.

Experimental: Interventional, single-arm, prospective, open-label, adaptive pilot study
Participants will undergo up to three unstimulated transvaginal oocyte retrievals targeting visible 4-9 mm antral follicles, without ovarian stimulation or ovulatory trigger medication.
Retrieved oocytes will undergo CAPA-IVM (Capacitation In Vitro Maturation), ICSI (Intracytoplasmic Sperm Injection), blastocyst culture, PGT-A (Preimplantation Genetic Testing for Aneuploidy), embryo vitrification/accumulation, and single euploid embryo transfer if a suitable embryo is available.

The CAPA-IVM System Kit will be used in the laboratory to support collection, handling, capacitation, and maturation of immature cumulus-oocyte complexes retrieved from visible 4-9 mm antral follicles.
Participants will undergo up to three unstimulated transvaginal oocyte retrievals targeting visible 4-9 mm antral follicles, without exogenous gonadotropin stimulation or ovulatory trigger medication.
Retrieved oocytes will undergo CAPA-IVM followed by ICSI, blastocyst culture, PGT-A, embryo vitrification/accumulation, and single euploid embryo transfer if a suitable euploid embryo is available.
