In vitro fertilization (IVF) is a process of fertilization in which an egg is combined with sperm in vitro ("in glass"). The process involves monitoring and stimulating a woman's ovulatory process, then removing an ovum or ova (egg or eggs) from her ovaries and enabling a man's sperm to fertilise them in a culture medium in a laboratory.

Tissue culture is an important tool for the study of the biology of cells from multicellular organisms. It provides an in vitro model of the tissue in a well defined environment which can be easily manipulated and analysed. In animal tissue culture, cells may be grown as two-dimensional monolayers (conventional culture) or within fibrous ...
The term in vitro (lit. "within the glass") means the samples to be tested are obtained from a repository. In the case of cancer cells, a strain that would produce favorable results, then grown to produce a control sample and the number of samples required for the number of tests.
A bioassay is an analytical method to determine the potency or effect of a substance by its effect on living animals or plants (in vivo), or on living cells or tissues (in vitro). [1] [2] A bioassay can be either quantal or quantitative, direct or indirect. [3] If the measured response is binary, the assay is quantal; if not, it is quantitative ...
