Definition and principle of IVF and AI
IVF and AI are two kinds of assisted reproductive technologies, which play an important role in helping infertile couples achieve their reproductive aspirations. In vitro fertilization (IVF) and embryo transfer (ET) are the processes in which the fertilized eggs are cultivated to a certain stage and then transferred to the mother to continue their development and finally obtain a healthy baby. Artificial insemination refers to the process of combining sperm and egg in vivo by injecting sperm into female body.
Test tube babies first need to obtain female eggs and male sperm. If the quality of male sperm is poor or unable to provide sperm, artificial sperm extraction or testicular sperm extraction can be used to obtain sperm. Artificial insemination is to inject sperm treated semen into a woman's uterus or near the mouth of the cervix, so that sperm can fertilize by combining with eggs.
Indications for IVF and AI
IVF is suitable for a variety of infertile patients, including women with blocked fallopian tubes, endometriosis, low ovarian function, men with poor sperm quality or unable to provide sperm, and couples with chromosomal abnormalities. Artificial insemination is generally applicable to single women, couples who cannot have natural sexual intercourse (such as male sexual function problems), and men whose sperm quantity or quality is not ideal, resulting in inability to conceive naturally.
Success rate of IVF and artificial insemination
IVF is a complex technology, and its success rate is affected by many factors, including female age, ovarian reserve, and whether there are other infertility factors. Generally speaking, the success rate is negatively correlated with the age of the patient. The older the patient is, the lower the success rate is. According to the statistics of different hospitals, the success rate of IVF is generally about 30% to 60%.
Artificial insemination is relatively simple and has a high success rate. The success rate of artificial insemination in regular hospitals is usually between 10% and 30%. Success rates often vary depending on individual differences and the skill level of doctors.
Advantages and disadvantages of IVF and AI
The advantage of IVF is that it can help many infertile couples achieve their fertility aspirations, and at the same time, it can carry out a series of genetic screening and gene testing to improve the health quality of infants. However, the cost of IVF technology is high, and there may be a risk of complications during the operation.
The advantages of artificial insemination are simple, convenient and relatively high success rate. For some couples who cannot conceive naturally, artificial insemination is an effective choice. However, artificial insemination can not solve some severe infertility problems, and the success rate is relatively low.
Summary
IVF and AI are two common assisted reproductive technologies. IVF helps infertile couples achieve their fertility aspirations through in vitro fertilization and embryo transfer. The indications are wide, and the success rate is between 30% and 60%. Artificial insemination is the process of injecting sperm into a woman's body to achieve fertilization. The indications are relatively limited, and the success rate is between 10% and 30%. Both have their own advantages and disadvantages. It is necessary to select appropriate assisted reproductive technology according to the specific conditions of patients.
