The number of treatments with donated oocytes has risen markedly in Denmark during the latest decade due to changes in legislation and because female age is increasingly advanced when fertility treatment is warranted. Today, oocyte donation is a standard procedure offering the otherwise untreatable a high chance of achieving a pregnancy.

Immature oocyte retrieval with in-vitro oocyte maturation
Current Opinion in Obstetrics and Gynaecology, 1999Early studies of in-vitro fertilization used immature oocytes. The process evolved to retrieving metaphase II oocytes, and was eventually successful. At present, aggressive ovulation induction protocols are the mainstay of assisted reproductive technology programs, but not without increased cost, multiple gestations, morbidity, potential future risks ...

Human oocyte cryopreservation is potentially an alternative solution to the ethical problems arising from embryo storage. In addition, oocyte freezing is the only method to preserve the reproductive capacity for women at risk of losing it because of premature ovarian failure, pelvic diseases, surgery, or antineoplastic treatments.

Biochimie, 1979
The main elements of reproduction are exposed with emphasis on its preparation during the larval stage. The system oocyte-nurse cells-follicular cells is described and the principal features of egg morphogenesis are indicated. Two types of problems are concentrated on : 1) sequential determination of growth and evolution of the follicle in the ovarian ...

Use of donor oocytes is becoming an increasingly important facet of assisted reproductive technology programs. Candidates for donor oocytes include women with premature ovarian failure or severe genetic disorders, women who respond poorly to human menopausal gonadotropin, and women older than 40 years who do not conceive with used of other therapies ...

Best Practice & Research Clinical Obstetrics & Gynaecology, 2002
Oocyte donation affords women with ovarian failure, advanced reproductive age, heritable conditions or recurrent implantation failure the ability to conceive. Recipients must be medically screened carefully prior to attempting pregnancy. Egg donors should also be healthy and pose no infectious or genetic risk to the recipient or offspring.

Cloning and Stem Cells, 2005
In assisted human reproduction, the cytoplasm of oocytes recovered from follicles is often abnormal. Its lower quality, especially in older patients, may be responsible for certain chromosomal abnormalities or developmental arrest. Thus, the deficiency of some vital molecules, which are necessary for oocyte maturation, can be the cause of infertility ...

Cytoplasmic polyadenylation in mammalian oocyte maturation
Wiley Interdisciplinary Reviews - RNA, 2016Oocyte developmental competence is the ability of the mature oocyte to be fertilized and subsequently drive early embryo development. Developmental competence is acquired by completion of oocyte maturation, a process that includes nuclear (meiotic) and ...

Oogenesis in the anuran Xenopus laevis can be divided into six stages based on the anatomy of the developing oocyte. Stage I consists of small (50 to 100 μ) colorless oocytes whose cytoplasm is transparent. Their large nuclei and mitochondrial masses are
