What is Embryo Transfer and How Does it Work in Thailand?

Introduction: Embryo transfer is a crucial stage of the in vitro fertilization (IVF) process, which plays a vital role in aiding couples experiencing difficulties with natural fertilization. This article delves into the intricacies of embryo transfer, exploring its necessity, preparation, the actual process, follow-up appointments, different types, factors influencing the number of embryos to be transferred, success rates, and potential risks. Understanding these aspects is essential for individuals seeking IVF and embryo transfer treatment in Thailand, as it will provide them with valuable insights and knowledge for this critical stage of the fertility journey.

Understanding Embryo Transfer in IVF Treatment

Embryo transfer is the final step in the in vitro fertilization (IVF) process. This involves using fertility medication to stimulate egg production in the female, followed by the removal of eggs and fertilization in a laboratory. The resulting embryos are then returned to the woman’s uterus, initiating the pregnancy process.

When is Embryo Transfer Needed?

Embryo or IVF treatment may be necessary when natural fertilization presents challenges, such as damage to the fallopian tubes, ovulation problems, irregular egg release, male fertility issues, or genetic disorders.

Preparation for Embryo Transfer

Prior to embryo transfer treatment, the healthiest eggs are meticulously selected by medical professionals at the IVF clinic, typically around two or three days before the transfer. Any surplus high-quality embryos can be frozen for future use.

The Embryo Transfer Process

The embryo transfer procedure, while straightforward, may involve some invasive measures. Similar to a pap smear test, a speculum is used to keep the woman’s vagina open. Ultrasound is employed for accuracy in placing the embryo into the womb, and the entire process usually takes about ten minutes. Sedatives can be requested, although they are not commonly needed.

Follow-up Appointments and Considerations

A follow-up appointment is usually scheduled approximately two weeks after the embryo transfer to determine if the embryo has successfully implanted in the womb. Mild vaginal discharge, cramping, and bloating may be experienced after this appointment. Different Types of Embryo Transfer of IVF Treatment

Different Types of Embryo Transfer

Following the fertilization of eggs, different transfer options may be utilized, including fresh embryo transfer, frozen embryo transfer, blastocyst transfer, and assisted hatching (AH), each with its unique considerations and potential success rates.

The number of embryos typically transferred varies and is often determined based on various factors, including the patient’s age and health, the quality of the embryos, and the clinic’s guidelines.

Seeking professional medical guidance during the embryo transfer process is essential. At First Fertility, we understand the importance of meticulous care in selecting and transferring embryos. We’ve seen how personalized care and attention to detail can significantly impact the success of the procedure and ultimately the chances of a successful pregnancy.

Embryo Transfer in IVF

The number of embryos that are transferred back to the female’s uterus is often dependent on the female. In some cases, only one fertilized egg can be transferred, although in many cases, doctors prefer to transfer two or maybe more embryos to increase the chances of becoming pregnant. There is plenty of debate where this is actually necessary.

Factors Affecting Number of Embryos

Current guidelines outlined by the International Journal of Gynaecology and Obstetrics suggest that the female’s age and outlook should be the main determining factors with regards to how many eggs are transferred. Women over the age of 35 typically have two or more fertilized eggs implanted with females under 35 usually only one embryo is transferred. The chances of birth defects are also higher in women over the age of 38.

Success Rates of Embryo Transfer

According to a study published in the International Journal of Reproductive Medicine rates with frozen embryos are around 18 per cent with this figure varying from the mean average with age. According to other studies, it appears that the success rates experienced with fresh and frozen embryos are very similar with both forms of IVF producing very similar results. As techniques improve, success rates will naturally increase, bringing joy to more couples.

Several other factors may also play a more significant effect on success rates. The reason for the problems conceiving naturally is a big factor as too is age, ethnic backgrounds and genetic disorders. Unfortunately, the quality of the clinic or hospital can have a significant impact, especially in countries where regulations aren’t as strict. It is advisable to do your own research before deciding which clinic you will use.

Potential Risks and Sensible Precautions

The process of embryo transfer carries very few risks; however, it is impossible to remove the risk entirely. The most common risks are related to the hormone stimulation, which has been linked to increased risk of blood clotting, potentially causing embolisms or thrombosis.

Other potential side effects include vaginal discharge, bleeding, infections such as urinary tract infections, and complications that may arise when anesthetics are used. The risk of miscarriage is the same as those experienced with embryos that are formed via natural conception.

Multiple pregnancies, something that can be quite common, present itself as the most significant risk. Multiple pregnancies can increase the potential for stillbirth or congenital disabilities. Statistical evidence points to this being more prevalent in pregnancies from IVF.

Emotional and Physical Preparation

Of course, all couples should be made aware that there are no guarantees of success. Both parents should be prepared both physically and emotionally for something that will naturally be very stressful.

Conclusion: Understanding the process of embryo transfer, including its various types and potential risks, is crucial for couples considering IVF and embryo transfer treatment. It’s important to carefully consider all factors, including success rates and potential complications, before embarking on this journey. Seeking guidance from experienced medical professionals and thorough research on clinics can help couples make informed decisions as they pursue their dream of parenthood.
