What indications does IVF have?
IVF technology is a kind of assisted reproductive technology, which is used to help couples who cannot conceive in a natural way to achieve their reproductive aspirations. The indications of IVF vary from individual to individual. The following describes the indications of IVF from the aspects of physiology, medicine and genetics.
1. Physiological indications
The physiological indications of IVF mainly include female fallopian tube damage, uterine malformation, polycystic ovary syndrome and low quality of male sperm.
First, fallopian tube damage is one of the common causes of female infertility. The fallopian tube may be damaged due to infection, surgery or other reasons, resulting in the inability of eggs and sperm to meet in the fallopian tube. In this case, IVF technology can bypass the fallopian tube through in vitro fertilization and embryo transfer to achieve pregnancy.
Secondly, uterine malformation is also a cause of infertility. For example, endometriosis, intrauterine adhesions and other conditions may hinder the implantation and growth of embryos. With IVF technology, embryos can be cultured in vitro and transferred after the endometrium is ready, which improves the success rate of pregnancy.
In addition, polycystic ovary syndrome (PCOS) is a common endocrine disorder in women, which may lead to ovulation disorders and ovarian dysfunction. IVF technology can help these patients achieve pregnancy through ovulation induction and in vitro fertilization.
2. Medical indications
The medical indications of IVF mainly include irreversible obstructive spermatozoa (Azoospermia), irreversible obstructive vas deferens obstruction, transient testicular sperm obstruction and abnormal sperm function.
Irreversible obstructive sperm reduction means that the number of sperm in semen is extremely low or even no sperm. IVF technology can use sperm extraction technology or sperm donation to obtain sperm samples, and complete pregnancy through in vitro fertilization and embryo transfer.
Irreversible obstructive vas deferens obstruction is another major cause of male infertility. With IVF technology, sperm samples can be obtained by sperm extraction technology or sperm donation, and IVF can be achieved by directly injecting sperm into eggs.
In addition, in some cases of abnormal sperm function, IVF technology can also be used to help couples achieve their reproductive aspirations, such as low sperm vitality and abnormal morphology.
3. Genetic indications
The genetic indications of IVF mainly include carrying single gene disease, family history of hereditary diseases and fertility of patients with hereditary diseases.
For couples with single gene disease, IVF technology can screen embryos without disease by means of embryonic genetic screening (PGS) or single cell genetic diagnosis (PGD) for transplantation, so as to reduce the risk of children's disease.
For couples with known family history of hereditary diseases, IVF technology can screen embryos without disease genes through genetic diagnosis for transplantation, so as to reduce the probability of children suffering from diseases.
For couples who have suffered from serious genetic diseases, IVF technology can ensure that embryos are transferred without carrying disease genes through carrier screening and genetic diagnosis, so as to avoid passing diseases on to the next generation.
4. Summary
To sum up, the indications of IVF cover many aspects such as physiology, medicine and genetics. For those couples who cannot conceive naturally, IVF technology provides hope for them to realize their reproductive dreams. However, due to individual differences and medical conditions, not every couple who cannot conceive is suitable for using IVF technology. Therefore, it is recommended to consult a professional doctor before choosing IVF to understand their own indications and treatment plans in detail.
