How to carry out the pre-test of IVF
IVF is an infant conceived in the process of in vitro fertilization through assisted reproductive technology. In the early stage of IVF, doctors will carry out a series of examinations to ensure that the patient's physical condition is suitable for this birth method. The following will elaborate the whole process of IVF pre examination from four aspects: embryo examination, hormone examination, sperm quality examination and auxiliary technology examination.
Embryo examination
Embryo examination is an indispensable examination in the early stage of IVF, and its main purpose is to evaluate the quality and health of embryos. This examination is usually carried out when the embryo is 5 days old. The doctor will carefully observe the development, morphology, structure, cell number and other factors of the embryo. At the same time, if necessary, doctors will also carry out genetic and genetic tests to ensure that the patient's embryos are free of chromosomal abnormalities or genetic diseases, so as to increase the possibility of healthy birth of the baby.
In addition, embryo examination can also help doctors select the most potential embryos for implantation, thus improving the success rate of IVF pregnancy. Therefore, embryo examination is a crucial part of IVF pre examination.
Hormone test
Hormone test is an important means to evaluate the ovarian function and uterine status of patients in the pre-test of test tube infants. In this examination, the doctor will take a blood sample to measure the estrogen, progesterone, luteinizing hormone and other hormone levels in the patient's body. Normal hormone levels are essential for normal ovarian development and the smooth process of ovum retrieval.
In addition, hormone examination can also assess the thickness and hyperplasia of endometrium to ensure that the uterus of patients can provide a good implantation environment. If abnormal hormone levels are found, doctors may improve the ovarian activity of patients by adjusting drug dosage or treatment methods.
Sperm quality inspection
Sperm quality test is an important test for male patients in the pre-test tube baby. By evaluating the density, vitality, morphology and structure of sperm, doctors can accurately assess male fertility. Generally speaking, the higher the sperm density and vitality, the more normal the morphology, and the higher the success rate of IVF.
In sperm quality inspection, doctors will also pay attention to evaluating the antioxidant capacity of sperm in semen, which is of great significance for reducing the occurrence of chromosome and gene abnormalities. If the test results are not satisfactory, doctors may improve the quality of sperm by selecting, cultivating and processing sperm.
Auxiliary technical inspection
In the IVF pre examination, the auxiliary technology examination is an important basis to evaluate which kind of assisted reproductive technology is suitable for patients. Including oviduct patency inspection, uterine morphology inspection and abnormal tissue resection.
The inspection of oviduct patency is usually completed through pelvic endoscopy or radiography to ensure that the patient's oviduct is unobstructed and the ovulated eggs can enter the uterine cavity normally. Morphological examination of uterus is mainly conducted by ultrasound or hysteroscopy to assess whether the health condition and morphological structure of uterus are suitable for embryo implantation and embryonic development. The abnormal tissue resection is performed by surgical examination to remove any abnormal tissue that may affect the health of the baby.
Summary
The pre-test of IVF is an important step to ensure that patients are suitable for IVF, including embryo test, hormone test, sperm quality test and auxiliary technology test. Through these examinations, doctors can assess the fertility potential and health status of patients, and formulate the best treatment plan according to the examination results. Through careful examination and evaluation, the success rate of IVF has been improved, providing effective support for patients to achieve their dream reproductive goals.
