The oocyte is the largest cell in the human body and is extremely vulnerable. Retrieving an oocyte exposes it to considerable stress, including transfer from the follicle, passage through the needle and tubing, and exposure to the laboratory environment.
It is also a critical procedure involving a lot of anxiety for the patient.
One way to support a successful outcome is to use a needle that enables a fast and precise procedure. This will minimise stress and ensure that the maximum number
of intact oocytes can be retrieved.
Using a needle that causes minimal tissue damage will also lessen complications and patient discomfort.
The Sense needle has a 17G body and a 20G needle tip. This unique design provides ideal conditions for optimised control, aspiration time and improved patient comfort.
The reduced tip gives you the advantages of a small sized needle; less bleeding and less pain1,2,3. As only the tip is reduced, the rigidity and flow are maintained, ensuring accurate guidance while helping to maximise the number of oocytes collected.
With Sense you keep the benefits working with a conventional needle and gain the advantages of a thin needle. It makes sense.
To prove the benefits of the unique design of Sense, a prospective, randomised, multicenter study was carried out1. Oocyte retrieval using Sense resulted in significantly less vaginal bleeding compared to a conventional needle and a significantly reduced overall pain experience – 19% lower compared to a conventional needle. Most importantly, there were no differences in the number of oocytes with intact zona pellucida after aspiration, regardless of needle size.

Our needles are designed to optimise control and retrieval time and improve patient comfort.
The echomarking is created through innovative laser etching giving you the high visibility you need during oocyte retrieval.
The needle tip is designed to meet your needs by providing extraordinary sharpness, exact precision and the utmost safety. The bevel grinding ensures low resistance penetration and distinctive backpoint grinding prevents deviation.
All needle labels are colour coded to simplify identification of needle type. The peel-off labels facilitate patient journal handling.
Each needle is individually packaged in a double sterile barrier to avoid contamination in the operating theatre.
To detect toxic materials, Vitrolife has developed a very sensitive 1-cell mouse embryo assay (MEA) that follows the development of single-cell mouse embryos to hatching blastocysts. This assay is far more sensitive than the widely used 2-cell MEA.

I use Sense for all patients and recognize its value for both my patients and myself. The clear view of the needle tip enables my control of the procedure at all times, whilst the thinner tip hasn’t altered the timing for each egg collection.
I've also seen much less bleeding and pain in my patients when using Sense, which is clearly positive for all involved!
