What Are The Advantages Of Embryo Transfer?
The advantages can be numerous:
Infertility: Embryo transfer is a good option for couples who have trouble becoming pregnant due to reasons like blocked fallopian tubes and endometriosis. It provides an alternative way for people to become pregnant and have children.
Genetic screening of embryos: We can test embryos for genetic disorders or chromosomal abnormalities before transferring them. This allows us to select healthy embryos and decreases the risk of passing on inherited diseases to future generations.
Fertility Preservation: People can preserve their fertility by freezing their embryos (cryopreservation) before undergoing medical treatments such as chemotherapy or radiation that may harm their reproductive organs. The frozen embryos can be transferred at a later time.
Timing Control: Embryo transfer allows you to have precise control over the timing of pregnancy. Such control can be particularly important for people undergoing fertility treatment or who need to adhere to a specific schedule.
Assisted reproduction for same-sex couples: With the help of embryo transfer, same-sex couples can have biologically related babies by using genetic material from one or both parents. For instance, one partner's egg can be fertilized with donor sperm, and the resulting embryos can be transferred to the other partner's uterus to conceive babies who are genetically related to one parent and carried by the other.
Reducing the risk of pregnancy complications: Embryo transfer may reduce the chance of certain pregnancy problems associated with advanced maternal age. This is because older eggs can be fertilized and grown in younger, healthier uterine conditions.
Dealing with repeated pregnancy losses: Couples who have suffered multiple miscarriages may choose to combine embryo transfer with pre-implantation genetic testing to select embryos with a lower risk of chromosomal abnormalities. This could decrease the probability of the couple experiencing another pregnancy loss.
The probability of conception following embryo transfer (ET) is influenced by a number of variables, including the woman's age, the quality of the embryos, and the ET procedure.
Usually, younger women have a higher chance of getting pregnant after embryo transfer. For example, a woman who is below 35 years old has a 40–50% chance of conceiving after a single embryo transfer with high-quality embryos. Women aged over 40 are about 20–30% less likely to get pregnant.
The quality of the embryos has a big impact on the likelihood of getting pregnant after an ET. Embryos that have a good or excellent grade are more likely to attach to the lining of the uterus.
The technique used for ET can also affect the chances of conception. The most common method, known as transcervical ET, involves transferring the embryos to the uterus by inserting a catheter through the cervix. This approach is reasonably safe and effective, achieving a success rate between 30 and 40%.
Another method, called intracytoplasmic sperm injection (ICSI), involves injecting a single sperm into each egg. This method is used for men with severe infertility. ICSI has a higher success rate than transcervical ET, but it is also more expensive and carries a slightly higher risk of complications.
It is usually possible to get pregnant after transferring the embryo. However, there are several factors that might affect the outcome. Women who are younger than 35, have high-quality embryos, and work with a competent and experienced team have a better chance of success during ET.
