Bodily fluid collection systems are described where the system may be used for collecting and transferring sperm into a syringe. The syringe is configured to have a distal collection tip which is gently tapered or radiused to present a smooth and atraumatic surface and which is specifically configured and shaped to be inserted within and received by the collection receptacle. The distal collection tip has a shape which corresponds directly to a tapered reservoir defined at the bottom of the collection receptacle such that a distal opening defined through the tip is optimally positioned within the concentrated bodily fluid pooled within the reservoir for collection. Moreover, the gentle taper of the collection tip may present an atraumatic surface for inhibiting damage to the sperm contained within the ejaculate as the sperm is suctioned into the distal opening for insemination into the female.

An apparatus for collecting seminal fluids, and specifically an artificial cervix for collecting seminal fluids for artificial insemination, is provided herein. The cervix comprises an elongated cylindrical member having either a closed end for receiving and storing ejaculated semen or an open end for allowing ejaculate to pass through, and an open end having a rim of a diameter sufficient to receive the penis of the animal. A handle can be detachably connected to said cylindrical member that allows users to hold the cervix in the correct position during collection of the animal's seminal fluids.

The invention encompasses improved catheters comprised of multiple tubular bodies and methods of using them in artificial insemination.

Intravaginal devices for presenting ejaculate produced during sexual intercourse to the cervix while inhibiting exposure to the intravaginal environment and associated methods are disclosed herein. An intravaginal device configured in accordance with embodiments of the present technology can include, for example, a tubular body having a first concave surface that defines a first depression at which to collect ejaculate produced during sexual intercourse, a second concave surface that defines a second depression at which to present the ejaculate to the external os, and a flow channel defined by an inner surface of the tubular body extending between the first and second depressions. Because ejaculate deposited into the first depression travels to the second depression through the flow channel, exposure to the inhospitable conditions of the intravaginal environment is limited. Moreover, by guiding the ejaculate through the external os, the intravaginal device may serve to increase intrauterine sperm count.

The invention encompasses improved catheters comprised of multiple tubular bodies and methods of using them in artificial insemination.

The device (1) comprises an inlet element (28) comprising an interface (40) for connecting to an artificial vagina and delimiting an inlet opening (14), a filter associated with the inlet element (28) and delimiting therewith an inlet chamber (41) on the side of a first face of the filter turned towards the opening (14) and a collection bag (4) extending between a closed end (8) and an end (7) having an opening (6) in which said inlet element is engaged; said bag and said filter delimiting a collection chamber (42) on the side of the second face (18) of the filter turned towards the end (8); by means of which semen entering through the opening (14) passes through the filter and is collected in the collection chamber (42); characterized in that the filter is formed by a perforated wall (30) in one piece with the inlet element.

The present invention relates to a method and apparatus for passive collection of sperm having improved motility from a semen sample. The semen sample is contacted with on side of a porous barrier and a nutrient-containing media is contacted with the other side of the porous barrier. More robust sperm migrate from the semen sample through the porous barrier and are collected in a nutrient-containing media.

Artificial vaginas are disclosed that include an elongate housing, a liner within the elongate housing that is attached to the elongate housing, and a pressurized air tank arranged to bring the artificial vagina to an appropriate pressure. Such artificial vaginas may be brought to an operation temperature for the collection of semen by an air infuser that may contain a blower, a heating element and a shaft having a plurality of apertures through which heated air may flow.

A behavioral training aid comprising: (a) a body; (b) a tract including: (i) a tract locking mechanism that secures the tract to an outer surface of the body; and (ii) a tract insert removably attached to the tract locking mechanism; (c) one or more legs extending from the body; and (d) one or more base supports extending from a distal end of the one or more legs; wherein the tract insert is configured to receive a receptacle so that the receptacle is elongated and forms a depository within the body.
