Concept of IVF
Test tube baby, also known as artificial insemination baby, refers to the process of combining sperm and eggs in the laboratory and cultivating them into embryos through in vitro fertilization (IVF), and then implanting the embryos into the mother's uterus to achieve pregnancy and delivery. IVF technology has become a way for many couples who cannot conceive naturally to realize their dreams.
The process of IVF birth has gone through several key steps, such as egg collection, sperm acquisition, in vitro fertilization and embryo implantation. The birth process of IVF will be introduced in detail below.
Egg collection
The first step of IVF is to collect female eggs. This process usually takes place in the second week of a woman's ovulation cycle. Under the guidance of ultrasound, doctors insert a slender needle into a woman's ovary to extract the mature eggs. This process is usually carried out under general anesthesia or local anesthesia to ensure the comfort and safety of patients.
The collected eggs were then sent to the laboratory for further operations.
Sperm acquisition
The second step of IVF is to obtain sperm. Men can provide sperm samples by manual ejaculation or urine collection. The laboratory doctor separates the sperm from the sample, and uses specific culture medium for preservation and treatment. In order to improve the success rate of fertilization, the laboratory usually carries out sperm washing procedures to separate the best quality sperm.
Once the eggs and sperm are ready, they can undergo the process of in vitro fertilization.
In vitro fertilization
The third step of IVF is in vitro fertilization. In the laboratory, eggs and sperm will be placed in a petri dish, allowing them to combine naturally. Laboratory conditions will simulate the environment in the human uterus to promote fertilization. Medical staff will monitor the process of fertilization and observe the formation of embryos.
Normally, two to five days after fertilization, the embryo will develop enough to carry out the implantation process.
Embryo implantation
The last step of IVF is embryo implantation. Doctors will choose a well developed embryo and use a slender catheter to implant it into a woman's uterus. This process is usually carried out under local anesthesia or without anesthesia. After implantation, women who wish to have a successful pregnancy need a period of rest to promote the implantation of embryos.
In a word, the birth process of IVF includes such key steps as egg collection, sperm acquisition, in vitro fertilization and embryo implantation. Each step is carried out in the laboratory of the hospital, relying on the professional medical team and advanced technical equipment. IVF technology provides an opportunity for people who cannot conceive in a natural way to achieve their reproductive aspirations.
