Oocyte retrieval

Improve aspiration and patient comfort, secure oocyte quality

Successful aspiration starts here

A successful follicle aspiration needs to be fast, precise and retrieve the maximal amount of undamaged oocytes without complications. It is a critical procedure involving a lot of anxiety for the patient, which also needs to be taken care of. 

Sense aspiration needle

Reduced needle tip without compromising aspiration time, control and oocyte safety.

The best of both worlds

Sense has a thin, 20 G, needle tip and a thicker, 17 G, needle body.

The unique design of Sense makes it an ideal needle to work with. It has the control and precision you need with optimal aspiration time. With Sense you keep the benefits of working with a conventional needle and gain the advantages of a thin needle.

Unique design

The reduced tip gives you the advantages of a small sized needle. As only the tip is reduced, the rigidity and flow are maintained, ensuring accurate guidance while helping to maximise the number of oocytes collected.

Proven performance

A prospective, randomised study by Wikland et al. found that oocyte retrieval performed with the Sense needle resulted in a greater number of patients with less than expected vaginal bleeding compared to a conventional 17 G needle. Further findings were that the use of Sense also resulted in a significantly reduced overall pain experience – 19% lower compared to a conventional needle. Regardless of needle size, there were no statistical differences in aspiration time, oocyte recovery and fertilisation rate.

Innovative echo marking for perfect control

The new echo marking is achieved through innovative laser etching to give you the high visibility you need during oocyte retrieval.

Sharpness in every move

During the development of the new echo marking, we also further refined the way we grind the needles. The result is an even sharper tip that enables a smooth penetration of the tissue1.

I find using the Sense needle means less pain for the patient. Sense causes less trauma to the ovaries (which in turn reduces the possibility of postoperative bleeding).

The SENSE needle also reduces the level of sedation needed. - in selected cases using the SENSE I have not needed sedation at all.

- Dr Safwat Ashour, London Women’s Clinic

My first choice is Sense single and double needles and the reason is simple, Sense needles are best for patients and have minimal side effects. There is less bleeding and less pain when using the Sense needles. I have no doubt that Sense needles, both single and double, are the best available today.

The only thing is that the doctor must use a special technique at OPU and the technique of learning how to use the Sense needles is very easy if doctors want to use it.

- Negjyp Sopa, Klinikchef og Vævscentersansvarlig Aleris-Hamlet Fertility, Søborg Denmark;

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!

Around since the beginning, used worldwide

Together with the pioneers in IVF, Vitrolife invented the transvaginal follicle aspiration needle with an ultrasound probe already in the 1980s. This technique has since then been used successfully worldwide.
