  • Method of in-vitro fertilization with spermatozoa separated into X-chromosome and Y-chromosome bearing populations
    Patent number: 9879221
    Abstract: An IVF system for successfully utilizing spermatozoa separated into X-chromosome bearing and into Y-chromosome bearing population for insemination. The IVF system includes fertilization medium that can shorten the time from insemination to cleavage and a portable incubator for the transportation of maturing oocytes and inseminated oocytes comprising a straw (19) and an incubation element (20) that can be sealed with a cap (22).
    Type: Grant

    Date of Patent: January 30, 2018
    Assignee: XY, LLC
    Inventors: George E. Seidel, Tae Kwang Suh, Kehuan Lu
  • Methods for separating frozen-thawed spermatozoa into X-chromosome bearing and Y-chromosome bearing populations
    Patent number: 8652769
    Abstract: Devices, compositions, and methods for handling, separating, packaging, and utilization of spermatozoa (1) that can be derived from previously frozen sperm samples collected from a male mammal. Specifically, techniques to uniformily stain (2) spermatozoal DNA even when derived from previously frozen sperm and separation techniques to separate and isolate spermatozoa even when derived from previously frozen sperm samples into X-chromosome bearing and Y-chromosome bearing populations having high purity.
