Cryolab Oocyte Retrieval Needles are specialist single-use needles used during trans-vaginal ultrasound-guided egg collection in IVF. Needle design directly affects follicular aspiration efficiency, oocyte recovery rate, and patient comfort. Key specifications include gauge, tip geometry, aspiration lumen diameter, and echogenic tip coating for ultrasound visibility. Retrieved oocytes are collected into round-bottom tubes, assessed, then denuded with denudation pipettes before vitrification using the CBS High Security Vitrification Kit and storage in CBS Daisy Goblets within a liquid nitrogen storage tank. Every component in this chain contributes to the clinical outcome.
