Abstract
This container assembly is closed by removable cover and includes a base formed by two transparent nested cup shaped inner and outer members spaced to define a closed thermal insulation chamber therebetween. The inner member has a diametral partition structure dividing this member into two compartments. The cover has two spaced nipples to which may be connected respectively to an aspiration tube and a needle assembly for discharging fluids or a wash from a follicle or another similar site, into the chambers when the cover is rotated to either one of two positions on the base. The cover may be replaced by a transparent, imperforate cover for reviewing the contents of the compartments by a microscope to detect the presence of an oocyte.
