Indications for IVF
IVF is a kind of assisted reproductive technology, which is widely used in couples who have difficulty or cannot conceive naturally. Indications are one of the key factors to determine whether a couple is suitable for IVF treatment. Next, we will elaborate on the indications of IVF from different aspects.
Feminine factors
Female factor is one of the important aspects of IVF indications. Main indications include:
1. Obstruction of fallopian tube: If the female fallopian tube is damaged or blocked, the egg cannot enter the uterus through the fallopian tube, which will affect pregnancy. IVF can avoid the fallopian tube problem by directly implanting the fertilized egg into the uterus.
2. The reason for infertility is unknown: some couples still cannot find a clear reason for infertility after a comprehensive examination. IVF can solve this problem through assisted pregnancy technology.
3. Uterine problems: If women suffer from habitual abortion, endometriosis or abnormal uterine development, IVF can provide an effective solution.
Male factors
Male factor is another important aspect of IVF indications. Main indications include:
1. Abnormal sperm: If the male suffers from abnormal sperm quality such as insufficient sperm quantity, low motility or high abnormality rate, IVF can use selected sperm for artificial fertilization to improve the pregnancy rate.
2. Azoospermia: If a man suffers from azoospermia, that is, there is no sperm in the semen, IVF can use semen extraction technology to obtain sperm, and then conduct artificial fertilization.
3. Genetic disease: If a man carries a genetic disease, IVF can select healthy embryos for implantation through embryonic gene screening technology to prevent the disease from being passed on to the next generation.
Age factor
Age factor is also one of the important reference standards for determining the indications of IVF. The fertility of women declines with age, especially those over 35 years old. Therefore, older couples often choose IVF to solve the problem of pregnancy.
In addition, for older women, IVF can also improve the probability of pregnancy by implanting multiple embryos. However, multiple pregnancy will also increase the risk of pregnant women and fetuses, so doctors need to carefully evaluate and manage.
Other factors
In addition to the above factors, there are other special circumstances that may also be indications for IVF:
1. Recanalization after ligation: If a woman has undergone ligation and later needs to have another child, IVF can achieve fertility through fertilized egg transfer.
2. Endometriosis: Endometriosis is endometriosis to other parts, resulting in infertility. IVF can solve this problem by transplanting fertilized eggs into healthy endometrium.
3. Genetic disease screening: there is a risk of serious genetic diseases in the families of both spouses, and healthy embryos can be selected for implantation by screening embryos carrying abnormal genes through test tube babies.
In conclusion, the indications of IVF mainly include female factors, male factors, age factors and other factors. Doctors will determine whether couples are suitable for IVF treatment through detailed medical examination and evaluation.
summary
IVF is an assisted reproductive technology, which is applicable to those couples who are difficult or unable to conceive naturally. Indications are one of the key factors to determine whether a couple is eligible for IVF treatment.
Feminine factors are important aspects of IVF indications, including fallopian tube obstruction, unknown causes of infertility and uterine problems.
Male factors are also important aspects of IVF indications, such as sperm abnormalities, azoospermia and genetic diseases.
Age factor is an important reference standard for determining indications, and female age will affect fertility more.
In addition, there are other special circumstances that may also be indications for IVF, such as recanalization after ligation, endometriosis and genetic disease screening.
Doctors will determine whether couples are suitable for IVF treatment through detailed medical examination and evaluation.
