Sperm processing

Sperm processing
      • Good fertilisation rates requires high quality sperm
        A semen sample will always contain a mixture of functional and non-functional spermatozoa. Selection of functional sperm cells is required for the fertilisation procedure. To obtain a good fertilisation rate and resulting good quality embryos, the semen sample needs to be prepared so that the spermatozoa of highest quality can be obtained and used for fertilisation. 
      • Microcell for semen assessment
        To determine semen quality an assessment step is used at which motility and number of spermatozoa is determined. The MicroCell is a single use counting chamber for semen assessments. The MicroCell does not require mounting of coverslips or cleaning and can be used for 2 or 4 semen samples.
      • SpermRinse™ for semen preparation
        The swim-up migration technique is a simple preparation method commonly used for normal semen samples. SpermRinse is a HEPES buffered medium for sperm preparations. It contains the necessary carbohydrates and antibiotics for maintained sperm function. 
      • SpermGrad™ - efficient separation for increased progressive motility
        The density gradient separation technique is probably the most common method for sperm preparation worldwide. Normal spermatozoa, abnormal spermatozoa, other cells present in the semen sample and bacteria all have different densities. SpermGrad contains silica coated particles that allow for separation of spermatozoa and other cells according to their density.
      • SpermFreeze Solution™ maintains DNA integrity
        SpermFreeze Solution is used for freezing of semen samples. SpermFreeze Solution contains glycerol as a cryoprotectant and defined fatty acids, such as cholesterol for maintained sperm function after freezing and thawing. SpermFreeze Solution has been tested for effects on DNA integrity and is clinically proven to achieve fertilisation not only after ICSI but also when conventional IVF is used as the fertilisation method.
