Sense the difference
- Precision and performance in every retrieval
The Sense needle gives you the best of two worlds. The reduced tip in combination with the larger sized body work together in a unique way for the oocyte, the patient and you. You get uncompromised performance and improved patient comfort1-5.
The Sense needle offers unique performance with its reduced tip for less bleeding and pain, and a larger body for better control and precision1-5. The features of the Sense needle provides ideal conditions for oocyte retrieval as only the tip is reduced. Rigidity and flow are maintained, ensuring accurate guidance to collect the oocytes. With Sense you’ll keep the benefits of working with a conventional needle and gain the advantages of working with a thin needle.
Single or double? The choice is yours
There are two types of Sense needles: single lumen and double lumen. That means you can choose the needle that best suits your handling preferences while still ensuring high quality and performance.
Sense single lumen
The cross-section surface area of the Sense single lumen needle tip is 59% less than a conventional 17G needle tip. As only the tip is reduced, rigidity and flow are maintained, ensuring accurate guidance while helping to maximise the number of oocytes collected. Sense combines the benefits of a conventional needle with the advantages of a thin one.
Sense double lumen
Sense double lumen is based on the tried and trusted Sense single lumen needle, which features a reduced tip for less bleeding and pain and a larger body for optimal precision and retrieval time. Sense double lumen has the same reduced tip and larger body, while also adding the option of easy follicle flushing during pick up. The cross-section surface area of the Sense needle tip is 56% less than a conventional 17G needle tip.
Designed for uncompromised control
Echomarking for perfect control
Created through innovative laser etching, giving you the high visibility you need during oocyte retrieval.
Ultra-sharp design
For low penetration resistance and high precision. The needle tip is providing extraordinary sharpness, high precision and the utmost safety. The bevel grinding ensures low resistance penetration, while distinctive backpoint grinding prevents deviation.
The Sense needle is easy to handle
It is safe and convenient in your hands. The bevel mark on the handle indicates the needle position, while the soft tube and bent cannula prevent kinking and oocyte damage.
Colour coded peel-off labels
All needle labels are colour coded to simplify identification of needle type. The peel-off labels facilitate patient journal handling.
Double sterile pack to meet surgical standards
Each needle is individually packaged in a double sterile barrier to avoid contamination in the operating theatre.
Reduced needle tip
Reduced needle tip for less bleeding and pain, larger sized body for optimal control, precision and retrieval time.
The Sense family just got bigger
A single Sense needle with 16.5 G body and a tip of 19 G for optimal control and precision
The trusted Sense family just got a new member – a single lumen needle with the same concept you know – a reduced tip. The needle with a reduced tip combines uncompromised oocyte recovery and aspiration time with optimised comfort. Our new single lumen Sense needle has a 16.5 G body and a tip of 19 G, which makes it optimal for control and precision, while still reducing bleeding and pain1, 2, 3, 4.
It makes sense, and results prove it
The Sense needle gives you the best of two worlds. The results of two clinical studies demonstrate that the reduced tip in combination with the larger sized body work together in a unique way for the oocyte, the patient and you. You get improved patient comfort with uncompromised performance.1,4.
Patients experienced less pain, less bleeding and in need of less pain relief compared to the group using a standard needle4.
With Sense only 1 out of 20 requests more pain relief*
3 out of 4 women have less bleeding with Sense
Talking SENSE™ with Prof. William Ledger
The unique design of Sense provides ideal conditions for optimised oocyte retrieval performance and aspiration time as well as improved patient comfort.
In this video Prof. William Ledger shares his expertise and experience using the Sense follicle aspiration needle during oocyte reterival.
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!

Controlled manufacturing
Our manufacturing environment and processes meet the highest standards – to ensure consistently high quality of the final product. All needles are manufactured in a cleanroom where particle levels are thoroughly monitored daily.
Inspection of all needles
An experienced technician performs a microscopical inspection of every needle before release, ensuring the function and performance you expect and securing consistent quality.
Guaranteed sterility
All needles are sterilised using a validated process that is verified regularly to ensure patient safety.
Lot-to-lot consistency
Lot-to-lot consistency is secured by adhering to rigorous validated specifications and protocols. The quality of each lot is certified by a signed protocol to guarantee traceability. All stages of production are controlled, from raw materials to final product.
MEA tested
To detect toxic materials, Vitrolife has developed a highly 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.
