Steps of IVF conditioning
Test tube baby technology is one of the important achievements of modern medicine. It has realized the dream of fertility for some infertile couples. However, IVF needs to go through a series of steps to ensure the successful implantation of embryos into the mother. The steps of IVF conditioning will be described in detail below.
Physical condition assessment
The first step of IVF conditioning is to assess the physical condition. The doctor will carry out detailed physical examination on the couple, including women's ovarian function, uterine morphology and endometrial thickness, and men's sperm quality. In addition, the general health of the couple will be evaluated, including blood pressure, blood sugar, blood lipids and other indicators. Through evaluation, doctors can know whether the couple's physical condition is suitable for IVF.
According to the evaluation results, the doctor will develop a conditioning plan for individual conditions. For example, if the female ovary function is poor, ovulation induction therapy may be required; If the quality of male sperm is poor, lifestyle intervention before pregnancy preparation can be taken, such as smoking cessation, moderate exercise, healthy diet, etc.
The purpose of conditioning is to optimize the physical condition of couples and improve the success rate of IVF.
Ovulation induction
Ovulation induction therapy is one of the basic steps of IVF. It stimulates ovarian development and ovulation of follicles by using gonadotropins. Before the start of treatment, doctors will formulate individualized programs according to women's menstrual cycle, and adjust the dosage of drugs and treatment time.
Gonadotropin is usually given to patients by injection. During the treatment, doctors will regularly conduct ultrasound and blood tests to monitor the growth of follicles and changes in estrogen levels. When the follicle grows to a certain size, the doctor will use follicle stimulating hormone to trigger follicle ovulation.
The purpose of ovulation induction therapy is to obtain sufficient quantity and quality of eggs at the time point of IVF operation.
In vitro fertilization
In vitro fertilization is one of the core steps of IVF conditioning. During in vitro fertilization, the doctor will collect the eggs discharged by women and combine them with the sperm provided by men in a culture dish. In order to improve the fertilization rate, doctors may use auxiliary technologies, such as intracytoplasmic sperm injection (ICSI).
After fertilization, the embryo will be cultured in a petri dish for several days. Doctors will regularly check the development of the embryo and assess its quality. In the process of cultivation, doctors will continue to supplement progesterone and other drugs for women to promote the growth of endometrium.
Doctors will choose the best time to implant the embryo into the female uterus according to the quality of the embryo and the state of the female endometrium.
Embryo implantation
Embryo implantation is the last step of IVF conditioning. Before embryo implantation, the doctor will assess the thickness of the endometrium and examine the morphology of the uterine cavity. If the endometrium is suitable for embryo implantation, the doctor will select the best embryo for implantation.
Embryo implantation is usually a simple and painful process. Doctors will implant the well developed embryos after fertilization into the uterus of women through precise operation. After implantation, women need to rest and continue to use progesterone and other drugs to maintain the stability of the endometrium.
The conditioning process may take several weeks until a pregnancy test is performed. If the pregnancy is successful, the couple will enter the custody and management during pregnancy. If the pregnancy fails, the doctor will adjust the plan according to the specific situation and try again.
Summary
IVF conditioning is one of the important means to realize the fertility dream for infertile couples. It needs comprehensive conditioning through multiple steps such as physical condition assessment, ovulation induction therapy, in vitro fertilization and embryo implantation. Through reasonable conditioning measures, the success rate of IVF will be improved, bringing joy to couples in childbirth.
