Methods of IVF operation
IVF, or in vitro fertilization embryo transfer, is an assisted reproductive technology that can help couples who cannot conceive naturally achieve their reproductive aspirations. The following will introduce in detail the implementation methods of IVF surgery in terms of hospital selection, evaluation of indications, egg retrieval and sperm treatment, embryo culture and transplantation.
Select Hospital
It is very important to choose a hospital with rich experience and good reputation. The first-class IVF medical institutions are usually equipped with advanced equipment and professional teams, which can provide comprehensive assisted reproductive technology services. The following points can be referred to when selecting hospitals:
First, understand the professional background of the hospital and the qualification of doctors. Look for doctors and expert teams who are qualified to engage in IVF. They should have rich clinical experience and successful cases.
Secondly, understand the equipment and technical level of the hospital. IVF surgery requires advanced equipment and laboratory conditions, so selecting hospitals with advanced facilities can improve the success rate.
Finally, refer to others' opinions and feedback. You can seek advice from relatives and friends, or search the hospital's word-of-mouth comments on the Internet to learn about other people's experience and views.
Evaluate indications
Before IVF surgery, the doctor will conduct a comprehensive physical examination and birth history survey of the couple to assess whether they are suitable for IVF surgery. Here are some common indications:
1. Fallopian tube problem: if the fallopian tube is blocked or damaged, the fertilized egg cannot pass through the fallopian tube smoothly.
2. Male infertility: such as abnormal sperm quantity, vitality or morphology.
3. Female infertility: such as ovulation problem, polycystic ovary syndrome or endometriosis.
4. Unexplained infertility: infertility caused by unclear etiology.
Egg taking and sperm treatment
IVF surgery includes two processes: egg retrieval and sperm processing.
First, ovulation induction therapy is carried out for women to produce multiple follicles in the ovary. Through ultrasonic monitoring, determine the size and number of follicles, and then conduct ovarian puncture to collect the eggs.
At the same time, the man needs to provide fresh semen samples. If the man has problems with his semen, he can obtain sperm through sperm (including single sperm and sperm extracellular microinjection) or sperm extraction technology.
After obtaining eggs and sperm, they are placed in the culture medium for fertilization.
Embryo culture and transfer
In IVF surgery, the cultured embryos will be observed and evaluated in the incubator, usually lasting for 2-6 days. The time of embryo culture determines the selection of the embryo with the most development potential.
Embryo transfer is generally conducted 3-6 days after fertilization. The embryo is inserted into the female uterine cavity through a thin tube, and the accurate implantation of the embryo is ensured through positioning technology.
After embryo transfer, adjuvant treatment with progesterone and other drugs is also needed to promote embryo implantation and maintain early pregnancy.
summary
IVF surgery is a complex assisted reproductive technology. The implementation process includes hospital selection, evaluation of indications, oocyte retrieval and sperm processing, embryo culture and transfer, etc. The success rate of IVF surgery can be improved by selecting appropriate hospitals, evaluating indications and conducting careful operations, which can help infertile couples achieve their coveted reproductive aspirations.
