How did IVF successfully conceive?
IVF is a method of assisted reproduction through in vitro fertilization technology, which is widely used in the treatment of infertile couples. The following will elaborate on the successful pregnancy process of IVF from four aspects.
1. Preliminary preparation
The early preparation of IVF includes a comprehensive physical examination and evaluation of the couple to determine the cause of infertility and the most appropriate treatment. First, the doctor will check the female's ovarian function, and determine the follicular development and ovarian hormone levels through ultrasound and blood tests. At the same time, men need to carry out sperm quality inspection, including semen analysis and sperm function test.
According to the examination results, the doctor will make a personalized treatment plan. Generally, women need to receive ovulation promoting drugs to promote follicular development. Once the follicles have reached the ideal state, the doctor will arrange an egg retrieval operation.
2. Egg and sperm collection
Egg retrieval is an important part of IVF. Before surgery, women need to inject ovulation promoting drugs to increase the number of eggs. Egg retrieval is usually performed at the mature stage of egg development. Doctors use ultrasound guided fine needles to extract eggs. The eggs will be placed in a petri dish and wait to be combined with sperm.
At the same time, men need to provide fresh semen samples, or obtain sperm through sperm extraction technology, such as sperm harvesting or single sperm injection technology when sperm activity is low. Doctors will select high-quality sperm to combine with eggs to improve the probability of pregnancy.
Fetching eggs and sperm is an important step to ensure the success of IVF pregnancy, which requires strict monitoring and operation.
3. In vitro fertilization and embryo culture
In vitro fertilization (IVF) is a key step in IVF. In the laboratory, the extracted eggs and sperm are fertilized in vitro in a culture dish. In this process, doctors will choose high-quality sperm to combine with eggs to promote fertilization.
After successful fertilization, the fertilized egg will further develop into an embryo. The development of embryos requires specific media and conditions. The doctor will place the embryo in a culture dish to observe and evaluate its development. Generally speaking, doctors will wait for the embryo to reach a specific stage of development to improve the success rate of implantation of endometrium.
If multiple high-quality embryos develop, doctors can choose to freeze the remaining embryos for future use.
4. Embryo implantation and successful pregnancy
Embryo implantation is the final stage of IVF. Doctors use thin tubes to implant embryos into the female endometrium, usually in natural or artificial cycles. After implantation, the doctor will monitor the progesterone level to confirm whether it is successfully embedded.
If the embryo is successfully embedded and developed, the woman will become pregnant. Doctors will regularly check the development of embryos and the health of pregnant women, and provide necessary drugs and support to increase the probability of successful pregnancy.
Summary:
The process of IVF successful pregnancy includes preliminary preparation, egg retrieval and sperm acquisition, in vitro fertilization and embryo culture, as well as embryo implantation and successful pregnancy. Through reasonable treatment plan and professional operation of doctors, many infertile couples can achieve their dream of childbearing.
