Abstract
Semen and sperm cell processing and preservation systems, and methods of producing a mammal and methods of producing mammalian embryos are disclosed. The present invention is directed to sperm cell preservation, fertilization, and insemination, maintaining or enhancing sperm quality and addressing one or more sperm cell characteristics, such as viability, motility, functionality, fertilization rates, and pregnancy rates. Further, sperm cell characteristics may be addressed within the context of various collection, handling, separation, storage, transportation, usage, fertilization, or insemination techniques.

1-53. (canceled)
A method of producing a non-human mammalian embryo comprising:
- obtaining cryopreserved sperm cells;
- thawing the cryopreserved sperm cells;
- sorting the thawed sperm cells;
- cryopreserving the sorted sperm cells;
- thawing the twice cryopreserved sperm cells;
- fertilizing at least one egg with the thawed, twice cryopreserved sperm cells;
- and
- producing a non-human mammalian embryo.
The method claim of 63, wherein the step of establishing at least one sperm sample further comprises establishing a sample of the sperm cells capable of fertilization in vitro of at least one egg.
