Cytoplasmic transfer is a procedure in which the intracellular content of a healthy, high-quality egg is aspirated and injected into the patient’s egg prior to fertilization.
This technology improves egg quality and significantly increases IVF success rates. Scientific studies have shown that transferring healthy cytoplasm enhances egg cell function and boosts reproductive potential.
As one of modern medicine’s most innovative methods, cytoplasmic transfer offers couples a solution-oriented treatment option. It represents a breakthrough particularly for women of advanced maternal age or those with diminished ovarian reserve who wish to achieve pregnancy with their own eggs.
With age, egg quality naturally declines, negatively affecting fertility potential. However, cytoplasmic transfer restores this capacity, raising pregnancy rates considerably. It is also especially beneficial for patients with repeated IVF failures, as it supports mitochondrial function within the egg, thereby improving chances of a healthy pregnancy.
Another important advantage of cytoplasmic transfer is its potential to reduce the risk of passing on genetic disorders. Damaged mitochondria can be replaced with healthy cytoplasm, helping prevent the transmission of certain inherited diseases.
Cytoplasm contains essential organelles such as mitochondria, ribosomes, and the Golgi apparatus. Importantly, mitochondrial mRNA does not alter the genetic structure of the egg, as the egg’s genetic material remains safely stored and unchanged in the nucleus.
Frequently Asked Questions About Cytoplasmic Transfer
What is cytoplasmic transfer?
Cytoplasmic transfer is an advanced assisted reproductive technique in which cytoplasm from a healthy, high-quality egg is transferred into the patient’s egg before fertilization. The aim is to support egg quality and improve reproductive potential.
Why is cytoplasmic transfer used in IVF?
Cytoplasmic transfer may be used to improve egg function, support embryo development, and increase the chance of pregnancy in selected IVF patients. It is especially considered for women with poor egg quality, advanced maternal age, diminished ovarian reserve, or repeated IVF failures.
Who may benefit from cytoplasmic transfer?
Cytoplasmic transfer may be beneficial for women of advanced maternal age, patients with reduced ovarian reserve, couples with repeated unsuccessful IVF attempts, or women who wish to try achieving pregnancy with their own eggs despite poor egg quality.
How does cytoplasmic transfer improve egg quality?
The cytoplasm contains important cellular components such as mitochondria, ribosomes, and the Golgi apparatus. By transferring healthy cytoplasm into the patient’s egg, the procedure may support mitochondrial function and improve the egg’s ability to develop after fertilization.
Does cytoplasmic transfer change the baby’s genetic structure?
Cytoplasmic transfer does not change the nuclear DNA of the egg, because the egg’s main genetic material remains inside the nucleus. The transferred cytoplasm is intended to support cell function rather than alter the genetic identity carried by the nucleus.
What is the role of mitochondria in cytoplasmic transfer?
Mitochondria are energy-producing structures inside the cell. Healthy mitochondrial function is important for egg development, fertilization, and embryo growth. Cytoplasmic transfer may help support eggs with reduced mitochondrial activity.
Can cytoplasmic transfer help after repeated IVF failures?
Yes. Cytoplasmic transfer may be considered for patients who have experienced repeated IVF failures, especially when poor egg quality or reduced embryo development is suspected as a contributing factor.
Is cytoplasmic transfer suitable for women with low ovarian reserve?
Cytoplasmic transfer may be an option for some women with diminished ovarian reserve who want to improve the functional quality of their available eggs. Suitability should be determined after a detailed fertility evaluation.
Can cytoplasmic transfer reduce the risk of inherited mitochondrial diseases?
Cytoplasmic transfer may help reduce the risk of passing on certain mitochondrial-related conditions by supporting the egg with healthier cytoplasm. However, genetic risks must be evaluated individually with specialist guidance.
Is cytoplasmic transfer the same as egg donation?
No. In cytoplasmic transfer, the patient’s own egg is used, and only cytoplasmic material from a healthy egg is introduced to support egg function. In egg donation, the entire egg comes from a donor.
When is cytoplasmic transfer performed?
Cytoplasmic transfer is performed before fertilization during an IVF cycle. After the cytoplasm is introduced into the patient’s egg, fertilization is carried out in the laboratory.
Does cytoplasmic transfer guarantee pregnancy?
No. Cytoplasmic transfer does not guarantee pregnancy. Success depends on factors such as the woman’s age, ovarian reserve, egg quality, sperm quality, embryo development, uterine health, and overall IVF treatment plan.
Is cytoplasmic transfer safe?
Cytoplasmic transfer should only be performed in experienced IVF laboratories and after detailed medical evaluation. As with all advanced reproductive techniques, potential benefits, limitations, and risks should be discussed with a specialist.
How is cytoplasmic transfer different from standard IVF?
In standard IVF, eggs are fertilized with sperm without transferring cytoplasm from another egg. In cytoplasmic transfer, healthy cytoplasmic material is added to the patient’s egg before fertilization to support egg function and embryo development.
