Oocyte Cryopreservation Comparing Fresh and Vitrified Sibling Oocytes
NCT00986687 · View on ClinicalTrials.gov ↗
Study Summary
Vitrification is a method to cryopreserve biological specimens that are sensitive to chilling injury such as oocytes and embryos, and it has been employed with increased survival rate and live births (Hong et al., 1999; Kuleshova et al., 1999; Yoon et al., 2000; Chung et al 2000; Wu et al., 2001: Kuwayama et al 2006). In their study the researchers propose to directly compare oocyte survival, fertilizaton and embryo development between sibling oocytes. The Cryotop method of vitrification, which the researchers aim to investigate in their study, has been reported as the most efficient method for human oocytes cryopreservation (Kuwayama et al, 2005, Antinori et al, 2006, Lucena et al, 2006, Cobo et al, 2008). Follow up of over 200 infants conceived from vitrified oocytes (Chian et al, 2008) indicate that the mean birth weight and the incidence of congenital anomalies are comparable to that of spontaneous conceptions in fertile women or infertile women undergoing IVF treatment.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00986687
The ClinicalTrials.gov registry entry for NCT00986687 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 17 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is UConn Health, which has 176 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Infertility appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00986687 reports 1 study location spanning 1 distinct geographic area — top geographies include Connecticut. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
