Test tube baby inspection and preparation
IVF refers to the use of assisted reproductive technology to cultivate and develop the fertilized eggs in the laboratory, and then implant the embryos into the mother's uterus to help those couples who cannot conceive naturally due to physiological or reproductive barriers achieve their reproductive aspirations. In order to ensure the smooth progress of IVF, a series of inspections and preparations are required. The following is a detailed description of the examination and preparations required for IVF babies from the aspects of physical examination, gene testing, sperm and egg extraction, assisted reproductive technology selection, etc.
1、 Physical examination
Before the IVF procedure begins, the couple needs to have a physical examination to assess their health and fertility. Men need to conduct semen analysis to check whether the number, vitality and morphology of sperm are normal. Women need to undergo gynecological examination, including examination of uterus and ovary, as well as examination of endocrine and reproductive hormones. In addition, other relevant examinations, such as blood routine examination and infectious disease screening, are also required.
For women, physical examination also includes endometrial examination. In the IVF program, one of the keys to success is to ensure the health and proper thickness of the endometrium. If the endometrium is too thin or abnormal, it may affect the implantation and development of the embryo. Therefore, before IVF, endometrial biopsy and hysteroscopy are usually performed to ensure the health of endometrium.
2、 Gene testing
Gene testing is an important step in the preparation of test tube baby. This test can help couples understand their own genetic information, eliminate the risk of disease that may be inherited to their children, and ensure the health of the baby. Gene testing includes genetic counseling and autosomal gene testing.
Genetic counseling refers to the investigation of a couple's family genetic history by a doctor, and the corresponding genetic counseling and guidance for the couple. Autosomal gene testing can detect whether couples carry chromosome abnormalities, the possibility of genetic diseases and the risk of genetic diseases. Through the results of gene testing, couples can better understand their genetic background and choose more appropriate artificial reproduction technology.
3、 Extraction of sperm and eggs
In the process of IVF, male sperm and female eggs need to be extracted for in vitro fertilization. Men can obtain sperm through self collection of sperm samples or sperm extraction surgery. Women need ovarian stimulation and egg collection.
Eggs are usually collected through in vitro fertilization in assisted reproductive technology. First of all, doctors will inject women with ovarian stimulators to promote the development of polycystic follicles. Then, under the guidance of an ultrasound instrument under monitoring, the eggs were collected by puncture at an appropriate time.
The extraction of sperm and eggs is a crucial link in the process of IVF. The quality and quantity of the extraction should be guaranteed for subsequent IVF and embryo implantation.
4、 Selection of assisted reproductive technology
In the process of IVF, it is also necessary to select appropriate assisted reproductive technology. According to the physical conditions of the couple and the doctor's suggestions, the available assisted reproductive technologies include in vitro fertilization embryo transfer (IVF-ET), intracytoplasmic sperm injection (ICSI), top test tube babies, pre implantation genetic diagnosis (PGD), etc.
In vitro fertilization embryo transfer (IVF-ET) is one of the commonly used assisted reproductive technologies. After in vitro fertilization of sperm and eggs in the laboratory, the fertilized eggs are implanted into the mother's uterus for pregnancy. ICSI technology is to inject a single sperm directly into the egg, which is generally used for the poor quality of male sperm. PGD technology can screen embryos carrying genetic diseases through gene detection of embryos to avoid passing genetic diseases on to offspring.
To sum up, the examination and preparation of IVF babies include physical examination, gene testing, sperm and egg extraction, assisted reproductive technology selection, etc. Through these preparations, we can greatly improve the success rate of IVF and help couples to achieve their fertility aspirations.
Summary
The inspection and preparation of IVF babies is an important link to ensure the smooth process of IVF babies. Physical examination can assess the health status and fertility of couples. Gene testing can eliminate the risk of genetic diseases. The extraction of sperm and eggs ensures the material for in vitro fertilization. The selection of assisted reproductive technology is based on the specific situation. Through these preparations, the success rate of IVF can be improved and the health of infants can be guaranteed.
