What are the limits on the number of attempts of IVF?

IVF is an assisted reproductive technology, which provides a chance for couples who cannot conceive naturally to have their own children. However, IVF does not succeed in one attempt, and the success rate requires multiple attempts. The number of attempts of IVF is limited in the following aspects.

1. Age limit

The age of women is one of the important factors that affect the success rate of IVF. With the growth of age, the number and quality of female eggs will gradually decline, thus affecting the possibility of pregnancy. Generally speaking, the success rate of women over 35 years old trying IVF will be significantly reduced. Therefore, age is an important factor in limiting the number of IVF attempts.

In addition, the age of a woman will also affect the blood supply to the uterus, thereby affecting the implantation of embryos. With the increase of age, the blood supply of the inner wall of the uterus will decrease, reducing the probability of embryo implantation. This will also increase the number of IVF attempts.

2. Physical condition limitation

IVF needs a series of hormone therapy and auxiliary operations, which have certain requirements for women's physical conditions. Some women whose physical conditions are not suitable for IVF surgery, such as serious chronic diseases, severe anemia, severe hypertension, may be prohibited from IVF treatment.

In addition, the sperm quality of some men may also have an impact on the success rate of IVF. If the number or quality of male sperm is lower than a certain standard, they may not be able to conceive successfully, thus increasing the limit on the number of attempts.

3. Economic cost limitation

IVF is an expensive medical operation, involving a series of examinations, drugs and surgery costs. The cost of IVF will vary according to different hospitals, the complexity of the treatment process and the auxiliary technology used. This makes many families may not be able to bear the financial burden of multiple attempts, leading them to only try a limited number of times.

In addition, the success rate of IVF is not 100%, and even if it is tried many times, it cannot be guaranteed to be successful. Therefore, economic cost is also an important factor limiting the number of IVF attempts.

4. Psychological pressure limit

IVF is a process of heavy psychological burden for couples. The failure of every attempt will bring great disappointment and psychological pressure to the couple. Because each attempt requires a lot of emotion and energy, couples may feel too emotional pressure after experiencing many failures. This is also an important factor in limiting the number of attempts.

In conclusion, the number of attempts of IVF is limited by many factors, such as age, physical condition, economic cost and psychological pressure. These restrictions make it impossible for IVF to succeed in one attempt, and it requires multiple attempts to achieve successful pregnancy. Therefore, couples need to take these limitations into consideration and be mentally prepared when conducting IVF treatment.
