A device for artificially inseminating a mammal with sperm from a male breeding animal is disclosed, the sperm being introduced through the vagina of the animal into or onto the uterus of the animal which is to be inseminated. The device comprises a tube which can be moved on the uterus through the vagina of the animal which is to be inseminated, and a heatable chamber for accommodating a thin tube containing the sperm, and a drive for removing the sperm from the thin tube and the uterus-sided opening of the tube. The device comprises a mechanism enabling the thin tube to be moved out from the chamber into the tube.

A sperm wash device for collecting motile sperm includes a first chamber section for holding an unwashed semen sample, a second chamber section for holding sperm wash media disposed over and attached to the first chamber section, and a ledge separating the first chamber section from the second chamber section. The ledge includes a slot therein that is configured be filled with sperm wash media that does not get recovered. A slider is placed on the ledge. Characteristically, the slider is moveable between a first position and a second position. At the first position, the slider allows fluid communication between the first chamber section and the second chamber section. At the second position, the slider blocks fluid communication between the first chamber section and the second chamber section. A method of using the sperm wash device is also provided.

An apparatus for micromanipulation of biological material, includes a vessel (1) having a reservoir (2) wherein the vessel has a channel (3) formed in a portion of the reservoir, the channel including an intermediate restriction (4) dimensioned to resist passage of the biological material but allow passage of liquid treatment solutions.

A method for treating spermatozoa of an animal includes: irradiating the spermatozoa with light having wavelengths in a range of 390-420 nm at a fluence effective to increase motility of the spermatozoa by 75% or more.

The straw includes a tube (11) extending between a first end (16) and a second end (17) and includes a gas-permeable but liquid-impermeable plug (12). The tube (11) is made of a thermochromic material that reversibly changes colour at a pre-set temperature threshold, by virtue of which colour change the tube (11) has a first visual appearance if the temperature thereof is below the preset threshold and a second visual appearance that is different from the first visual appearance if the temperature thereof is above the preset threshold.

A bodily fluid transporting unit that includes a container with a syringe housing and a refrigerant pack in the container. The container is covered by a lid and the engagement of the container and the lid results in an air-tight and moisture-tight bodily fluid transporting unit.

In order to provide a device for thawing a preserved vitrified germ cell and a method for thawing the preserved vitrified germ cell, both of which device and method are capable of simultaneously achieving a high conception rate and an easier transfer operation, a thawing device (1) includes a carrying device (8), a tube (5), and a cold storage device (6), the tube (5) including, inside the tube (5), (i) a germ cell containing region (10) containing the carrying device (8), and being covered by the cold storage device (6), and (ii) a thawing solution containing region (11) containing a thawing solution, and the carrying device (8) coming in contact with the thawing solution which has been melted.

Designs of improved canisters for animal semen straw storage in Dewars with cryogenic liquid are described. In some embodiments, the canisters include a layer of cryogen-absorbent material and an inner layer of thermally conductive material including apertures oriented and positioned to direct cryogen vapor into the interior of the container.

A method for treating spermatozoa of an animal includes: irradiating the spermatozoa with light having wavelengths in a range of 390-420 nm at a fluence effective to increase motility of the spermatozoa by 75% or more.

The invention relates to a device (1, 21) for artificially inseminating a mammal with sperm from a male breeding animal, the sperm being introduced through the vagina of the animal into or onto the uterus of the animal which is to be inseminated. The device (1, 21) comprises a tube (2) which can be moved on the uterus through the vagina of the animal which is to be inseminated, and a heatable chamber (6) for accommodating a thin tube (7) containing the sperm, and a drive (13) by means of which the sperm can be removed from the thin tube (7) and the uterus-sided opening of the tube (2). The device (1, 21) comprises a mechanism enabling the thin tube (7) to be moved out from the chamber (6) into the tube (2).
