Specimen manipulation device for micro manipulation and biopsy in assisted reproduction and in vitro fertilization

An dish for use in micro manipulation of embryos, oocytes or other cells, said dish comprising:

• a) a well having an outer side wall;
• and
• b) a plurality of upwardly open pockets formed in said outer side wall, said pockets each having a downwardly tapered interior in which a cell settles by gravity to a lowest extremity of said tapered interiors of said pockets, and said pockets each including opposite conferging side walls formed integrally with said outer side wall of said well, said side walls having opposed end surfaces which are spaced apart from each other to form openings in said pockets through which a micro tool can access a cell disposed in each of said pockets.

A dish for separating highly motile sperm from less motile sperm, said dish comprising:

• a) a passage for containing a sperm sample, said passage having an entrance end and an exit end;
• and
• b) at least one dam disposed in said passage, said dam being operative to hinder movement of less motile sperm and allow passage of highly motile sperm injected into said entrance end of said passage whereby the more highly motile sperm will swim to said exit end of said passage and the less motile sperm will be unable to swim to said exit end of said passage.
