Oocyte is the cell of an ovary which is ready to undergo - cell division’ (meioticdivision - reduces chromosomes) to form up the ‘ovum’, i.e. the matured reproductive cell of the woman. Until 1983, there are no effective treatments for women who are facing tubal disease or premature or natural ovarian failure in the early days of IVF technology establishment. Not every women can donate their eggs, there are certain criteria and some screening procedures to become an oocyte donor. The major reason for this trend shift is due to the large population changes at particular sectors or regions.
What is an Oocyte donation process?
In this egg donation process, the egg from fertile women is donated to infertile women to be used in ART procedures like IVF. The women who receives the egg is not the biological mother to the child but will be recorded as mother. The donor egg is fertilized in the laboratories with the recipient spouse and the fertilized embryo is transferred to the recipient’s uterus.
Reasons for choosing oocyte donation
There are many reasons that a women can choose to use an egg other than her own when she is facing problems with infertility. Single men and gay couple can also use egg donation process along with surrogacy. Some reasons to choose oocyte donation are:
- Menopause in early age

Egg extraction process
- The matured follicle is observed using ultrasound
- Anesthesia is given to the patient while retrieval process
- Under the guidance of ultrasound a need is passed inside the vagina to get ovaries and follicle.
- The follicles contains fluids, which is extracted by the needle along with the attached eggs
- The fluid is then rinsed in culture media and the retrieved eggs are kept in small dishes for freezing.
- After retrieval, sperm and egg are put together in lab for fertilization process with IVF or ICSI procedures.
- The fertilized embryos after one day were checked and transferred into the uterus.
