At Xytex UK, sperm quality is our top priority. We are committed to providing you with donor sperm that is the industry’s most selective, most tested and most successful.

SELECTIVE

Our donors are chosen with you and your future family in mind. All donors entering the program since January, 2017 must pass a rigorous screening and testing process. They are evaluated for medical, personality, and behavioral characteristics.

TESTED

Xytex UK evaluates donors for hereditary conditions through an extensive medical and family history questionnaire and genetic testing for the most common inherited genetic conditions as recommended by leading medical organizations. Our donors are continually tested while in the program through physical exams, urinalysis and bloodwork, ensuring you receive the healthiest sperm.

SUCCESSFUL

To prove our commitment to providing you with the highest quality sperm, we adhere to the following industry-leading standards for each of our vials:

Procedure TypeVial TypeQuality Commitment
Intracervical Insemination
ICI ready (Unwashed)12.5 million motile sperm per thawed 0.5 milliliter unwashed vial (25 MOT)
Intrauterine InseminationIUI ready (Washed)10.0 million motile sperm per thawed 0.5 milliliter washed vial (20 MOT)
In-vitro FertilizationIVF (ART)5 million motile sperm per thawed 0.5 milliliter vial (10 MOT)
Intracytoplasmic Sperm InjectionICSI1 million motile sperm per thawed 0.5 milliliter vial (2 MOT)

*An unwashed vial is frozen in its most natural state, allowing sperm to remain in its natural seminal fluid.

**A washed vial separates the sperm from its natural seminal fluid and is frozen in a preserving fluid. Removing seminal fluid helps minimize cramping that can result from prostaglandins, hormones that cause the uterus to contract.

Xytex UK allows for up to a 25% variance from the total motile sperm cell guarantee for differences in readings between laboratories. For example, our guarantee for IUI ready (washed) vials is 10 million motile sperm per 0.5 milliliter vial (washed vial); with a 25% variance, 7.5 million motile sperm is acceptable and considered to have met the guarantee. In addition, Xytex UK recognizes that the published literature has established that sperm concentration measurement can be greatly impacted by the type of counting device used. Xytex UK prepares all of its vials with a Makler chamber; when disposable chambers are used by clinics to assess the post-thaw quality, a conversion factor will be applied to the calculation to compensate for this discrepancy. The variance and the conversion factor are independent calculations from one another.

It is the responsibility of the inseminating healthcare provider to maintain accurate records, should there be a quality concern, or subsequent infectious or genetic problems occur following the use of our specimen. Should there be a concern, a Quality Report will need to be submitted within 45 days of the thaw and applies to vials used within 60 days of receipt.  Please see the Xytex Forms page for the Quality Report.

Quality reports associated with treatment that results in a successful pregnancy, or successful fertilization in IVF cycles without a transfer, will not be considered, regardless of the total motile count of the specimen.

Quality guarantee is void if ownership is transferred prior to use.

Xytex UK’s liability for any specimen that does not meet the above guarantee shall be limited to the following, at Xytex UK’s discretion:

  • Supplying specimen replacement
  • Full or partial refund for the cost of the specimen
  • Shipping costs will not be considered unless the specimen arrives already thawed
  • Xytex UK shall not be held liable for any consequential of incidental damages, including but not limited to any additional or associated expenses incurred during treatment
