The present invention is a sperm collector with squeezing function. It includes a soft rubber body provided with a penis insertion passage and a container body provided with at least a top end cover and receives the soft rubber body. When the top end cover and the container body are engaged, the soft rubber body is confined within a cavity formed by the top end cover and the container body. When the top end cover is disengaged, a front end portion of the soft rubber body protrudes out of an opening of the container body. A pressing means is provided at a middle lower portion of the container body. When using the present invention, the user could press the pressing means to squeeze the penis insertion passage of the sperm collector. Accordingly, stimulation to penis is increased and better effect of sperm collection is achieved. In particular, since the present invention is also provided with a heating rod, lubricant pockets and electrical vibrators, which enable the user to reach a climax as quick as possible, thereby further enhancing the effect of sperm collection.

A sperm collection device includes an open / close unit including two open / close members openably and closably supported about a hinge and core pieces supported by the open / close members. The core pieces are configured to open and close with the open / close members and to form an insertion space when the open / close members are closed.

A microfluidic chip is provided for self-sorting highly motile, morphologically normal sperm cell with high DNA integrity from a fresh semen sample. The sperm self-sorting microfluidic chip has one ormore inlet chambers, and sperm collection outlet chamber(s), and the middle of the channel features various micro-fabricated structures in different geometrical shapes and orientations, with varyingperiodicities and patterns, such as an array of micro-fabricated pillars that facilitate the transport of the active and healthy sperm into the outlet chamber.

The invention discloses a poultry insemination apparatus, which comprises a squeezing head, a pressure storage section, a sperm storage section, a jet section, a working body, a pressure sucker and a scale mark; the poultry insemination apparatus is characterized in that the top of the working body is accommodated into the pressure sucker; the pressure sucker is of a conical body with upper side bigger than down side; the pressure storage section is arranged on the upper section of the working body, the sperm storage section is arranged on the middle section and the jet section is arranged on the lower section; the top port of the pressure storage section is manufactured in coordination with the bottom port of the squeezing head; the top port of the pressure section is inserted and sealed in the bottom port of the squeezing head; and the scale mark identifier is marked in the outer diameter of the jet section. The poultry insemination apparatus disclosed by the invention can be used for carrying out sperm collection and insemination on breeder cocks conveniently and rapidly, and also can be used for accurately calculating the ejaculatory amount of the breeder cocks, so as to achieve a purpose of inseminating rapidly and conveniently and to guarantee the smooth implementation of artificial insemination of the breeder cocks; and the apparatus is simple in structure, easy in manufacturing, simple and convenient in operation, accurate, clean and sanitary.

Sperm, oocyte, and embryo survival and function is improved in vivo or in vitro by the use of a polysaccharide containing arabinose, galactose and / or hexuronic acid. In particular, a nonspermicidal lubricant containing such a polysaccharide (e.g., gum arabic, pectin, or galacturonic acid) increases the fertilization potential of the sperm during coitus, artificial insemination or sperm collection. Similarly, a freezing medium containing a polysaccharide containing arabinose, galactose and / or hexuronic acid enhances sperm, oocyte, or embryo viability.
