Xiamen IVF - How is IVF realized?
Test tube baby, also known as in vitro fertilization embryo transfer (IVF-ET) technology, is a scientific method to assist pregnancy through in vitro laboratory operations. In Xiamen, many hospitals provide IVF technology, such as Xiamen Overseas Chinese Hospital, Zhongshan Hospital affiliated to Xiamen University, etc. The realization of IVF mainly includes diagnosis, preparation, egg retrieval, sperm treatment, embryo culture and embryo transfer. The realization process of IVF will be described in detail below.
1. Diagnosis and preparation
Before IVF, doctors will conduct a comprehensive physical examination and relevant medical diagnosis to ensure the couple's health and eliminate other fertility problems. This step is crucial for selecting the appropriate treatment scheme.
Later, the doctor will determine the treatment plan according to the examination results of both parties, and give detailed explanations and psychological counseling to the patients. Couples should also receive some necessary life habits and nutritional conditioning guidance to improve the success rate of pregnancy.
In addition, women also need to be treated with ovulation induction, and hormone therapy is used to promote the ovulation of multiple follicles from the ovary to prepare for egg retrieval.
2. Egg taking and sperm treatment
In the egg retrieval stage, women will inject ovulation stimulating hormone according to the planned ovulation cycle to develop and mature follicles. The doctor determines the best time for egg retrieval through ultrasonic monitoring and blood examination.
Egg taking is generally carried out in the operating room. The follicles discharged from the ovary are collected and separated into eggs by puncture technology. The eggs are then transferred to the laboratory for subsequent processing.
At the same time, the man provided semen samples, which were specially treated and washed to obtain the best quality sperm.
3. Embryo culture
In the laboratory, eggs and sperm combine to form fertilized eggs through in vitro fertilization (IVF) or single sperm injection (ICSI). The fertilized egg is then placed in a petri dish for embryo culture.
The embryo culture generally lasts for 3-5 days, during which the doctor will regularly observe the quality and development of the embryo. By evaluating the morphology and optical properties of the embryo, doctors can predict the possibility of pregnancy and select the healthiest embryo.
4. Embryo transfer
Embryo transfer is the last step of IVF. The doctor will select the best embryo and insert it into the female uterus through a thin tube (catheter). Embryos obtain new growth environment and nutrition in the womb, hoping to be able to successfully implant and develop into healthy fetuses.
Generally, anesthesia is not required for embryo transfer, and patients need to continue taking hormone drugs after operation to help embryo implantation and maintain pregnancy.
summary
Through the detailed elaboration of the above four aspects, we have understood the realization process of Xiamen IVF. IVF technology has solved the problem of fertility in many infertile couples and brought them joy of life. However, IVF technology also requires patients to carry out under the guidance of doctors, and the success rate is also affected by many factors. Before choosing IVF, couples should fully understand the technical principles and processes, and make decisions under the guidance of doctors.
