What tests do test tube babies need?
Test tube baby refers to a baby that is conceived and delivered by an infertile couple through artificial assisted reproduction technology. In order to ensure the healthy development of IVF, doctors need to conduct a series of examinations on both sides of the couple. The following will elaborate on the inspection items required for IVF from four aspects: genetic examination, reproductive system examination, progesterone examination and embryo evaluation.
Genetic examination
The purpose of genetic examination is to know whether the couple has genetic diseases or susceptible genes, so as to avoid the risk of genetic diseases. Usually, doctors will require both the husband and wife to carry out blood tests and gene mutation screening, such as common genetic disease mutation screening, autosomal genetic disease mutation screening, etc. In reality, infertile couples may need more detailed genetic examination based on their own genetic history.
In addition, couples can also choose to conduct genetic counseling and genetic counselor evaluation to obtain more information about genetic risks and genetic diseases.
Reproductive system examination
The reproductive system inspection is mainly a comprehensive inspection and evaluation of the reproductive system of both spouses. For women, the common inspection items include uterine and fallopian tube permeability inspection, intrauterine foreign body inspection, endometrial thickness inspection, etc. These examinations can assess the function of female reproductive system and disease risk.
For men, semen analysis is generally conducted to check the number, vitality, morphology, concentration and other indicators of sperm. In addition, men may also need to undergo testicular ultrasound examination, testicular spermatogenesis function examination, etc. to assess the health of their reproductive system.
After the reproductive system examination, the doctor will formulate appropriate treatment plans based on the examination results to improve the pregnancy success rate.
Progesterone test
Progesterone is a hormone produced by the ovary and plays an important role in maintaining pregnancy. During IVF treatment, doctors usually regularly test the progesterone level of female patients. By checking the progesterone level, we can know whether the luteal function is normal and whether it is necessary to supplement progesterone to improve the pregnancy rate.
The progesterone test can be conducted through blood samples or urine samples, generally about one week after ovulation. This examination item is of great significance for the success rate of IVF, which can help doctors adjust the treatment plan in time and improve the pregnancy rate.
Embryo evaluation
Embryo evaluation is a very important step in IVF treatment. Through embryo evaluation, we can screen the most potential healthy embryos and improve the chances of successful implantation.
Embryo evaluation includes morphological evaluation and genetic evaluation. Morphological evaluation: Observe the morphological characteristics of the embryo through a microscope to evaluate its development and quality. Genetic evaluation can detect whether there is chromosome abnormality in the embryo through gene detection technology. Relevant inspection items include genomic guanylate polymorphism technology, fatigue recovery technology, etc. Through embryo evaluation, the best embryo can be selected for implantation to improve the survival rate of IVF.
Summary
IVF requires a series of tests, including genetic tests, reproductive system tests, progesterone tests and embryo evaluation. These examination items can help doctors understand the physiological conditions of both spouses, evaluate treatment plans, screen the most promising embryos, and improve the probability of successful pregnancy. Through comprehensive inspection and evaluation, the healthy development of IVF can be effectively guaranteed.
