Oocyte selection

Oocyte selection is a procedure that is performed prior to

embryo selection
takes place after fertilization.

Not all women can conceive naturally, leaving them with a need for technologies and research that can help them have children. Women who might not be able to have their kids naturally may have the option of in vitro fertilization. In vitro fertilization can be a series of treatments that involves the fertilization of a mature egg with a sperm in a laboratory.[1] Oocyte selection is a part the process for in vitro fertilization.[2] An Oocyte is an egg/ovum that is not fully mature or developed and has not been fertilized; Therefore an oocyte is an undeveloped ovum.

Process

This illustrates the process for accessing oocyte quality before in vitro fertilization

Selecting an oocyte for in vitro fertilization involves assessing the quality of the oocyte which is usually done by accessing the morphological features of the oocyte. The major parts of the oocyte that are accessed for quality in terms of morphological characteristics are the cumulus cells, zona pellucida, polar body, perivitelline space, and cytoplasm; These are the main parts of the oocyte and are usually assessed by conventional microscopy.

metaphase I (MI) oocytes (58.5% vs. 43.9% and 5.7 vs. 5.0, respectively).[5]

Also, morphological features of the oocyte that can be obtained by standard

compaction, blastulation and pregnancy.[7]
