Seattle Sperm Bank, Arex Life Sciences Partner to Expand Access to Advanced Functional Sperm Analysis

SEATTLE and WATERTOWN, Mass., Oct. 20, 2026 /PRNewswire/ -- Seattle Sperm Bank, one of the world's leading sperm banks, and Arex Life Sciences, a leader in advanced male fertility evaluation, today announced a strategic partnership to expand testing options using Arex's novel Kinetix™ Sperm Assay for clients participating in Seattle Sperm Bank's Directed Donor programs.

Through the partnership, Seattle Sperm Bank clients now have access to the Kinetix Assay, an advanced functional sperm analysis designed to provide information beyond conventional semen analysis. Kinetix results can help determine whether a sperm sample has the functional capability to fertilize an egg and when optimal ART procedure timing should occur—providing useful, predictive information about a sample's quality before committing it to long-term cryopreservation or use in a fertility treatment.

"Seattle Sperm Bank is proud to partner with Arex Life Sciences to give our clients access to the additional insights provided by the Kinetix Assay," said Angelo Allard, General Supervisor at Seattle Sperm Bank. "We are continually looking for ways to advance the quality and value of the services we provide. While conventional semen analysis remains an important part of sperm evaluation, Kinetix can provide additional information about sperm function that may be valuable to individuals and couples planning for future fertility treatment."

"We are pleased to welcome Seattle Sperm Bank and its clients to the benefits and insights of the Kinetix Assay," said Barb Cohen, PhD, Founder and CEO at Arex Life Sciences. "Seattle Sperm Bank's longstanding commitment to quality, rigorous screening and scientific excellence aligns closely with our mission to advance male fertility evaluation. Together, we are making functional information about a Directed Donor sperm sample available earlier in the fertility journey, when it can help individuals and clinicians make more informed preservation decisions for their future family planning."

The Kinetix Assay is available for Directed Donor clients through Seattle Sperm Bank as an added testing option.  You can learn more at https://www.seattlespermbank.com/arex/ or by email [email protected].

About Seattle Sperm Bank Directed Donor Program

Seattle Sperm Bank's Directed Donor program provides individuals and couples with a structured pathway for sperm donation involving a known donor. These programs are designed to support the collection, screening, processing, testing and cryopreservation of sperm while providing clients with the quality standards and guidance expected from an established sperm bank. Through its collaboration with Arex Life Sciences, clients now have the option to access the Kinetix Assay for additional functional information about their sperm sample prior to long-term storage or fertility treatment.

About the Kinetix™ Sperm Assay

Developed by Arex Life Sciences, the Kinetix™ Sperm Assay provides functional sperm analysis beyond conventional semen analysis. By tracking changes in an Fc Receptor (FcR) protein associated with sperm capacitation over time, the assay reveals a sperm sample's readiness to fertilize an egg, identifies optimal fertility windows and helps determine which procedure is most likely to succeed—insights no other semen analysis provides collectively.

Clinical research has demonstrated meaningful differences in assisted reproductive outcomes, including doubled pregnancy rates in IUI and nearly 3-fold higher yields of Day-5 Good-Quality Blastocysts in ICSI.

By providing functional insights before fertility treatment or long-term preservation, the Kinetix Assay helps clinicians make more informed decisions about sperm sample use.
