How many cycles does IVF take to succeed?
IVF technology is a kind of pregnancy aid method. Through assisted reproduction technology, the fertilized eggs are cultured in vitro, and then the well developed embryos are implanted into the mother for pregnancy, so as to achieve the purpose of assisted reproduction. However, IVF is not a one-time success, it needs to go through multiple cycles to achieve. The cycle required by IVF will be described in detail from several aspects below.
Advantages and success rate
The IVF technology has unique advantages over other pregnancy aid methods. First of all, IVF technology can bypass the main causes of infertility, such as fallopian tube blockage, poor sperm quality, and increase the fertility opportunities of infertile couples. Secondly, IVF technology can conduct embryo screening, reducing the risk of genetic diseases such as chromosome abnormalities. In addition, IVF technology has been widely used worldwide. Some excellent hospitals have advanced equipment and professional medical teams, which further improve the success rate.
However, the success rate of IVF is not high. According to statistics, the success rate of IVF in every country in the world is between 40% and 60%. As IVF technology is a complex medical technology, its success rate is affected by many factors, including female age, quality of fertilized eggs, endometrium and technical level of the medical team.
Specific process of cycle
The IVF cycle usually includes the following main steps:
1. Ovulation promotion: Through the use of ovulation promotion drugs, control the ovarian function of women, and promote the simultaneous development and maturation of multiple follicles.
2. Egg retrieval: doctors use minimally invasive surgery guided by ultrasound at the appropriate time to puncture mature follicles and collect eggs.
3. Sperm taking: The male provides semen samples, which are processed to obtain high-quality sperm.
4. Fertilization: contact the obtained eggs with sperm in an in vitro culture dish to fertilize them.
5. Embryo culture: The fertilized embryos will continue to be cultivated in the in vitro culture dish for several days to evaluate the quality of the embryos.
6. Transfer of embryos: doctors select high-quality embryos and implant them into women's uterus in the hope of a successful pregnancy.
According to different situations and doctors' suggestions, frozen embryos are sometimes selected for preservation, so as to implant in later cycles and increase the success rate.
Uncertainty of success time
The IVF cycle requires several attempts to achieve success. Usually, doctors will recommend 3 to 6 cycles, but it is not guaranteed that every cycle will be successful. This is because the success rate of IVF is affected by many factors, including the professional level of the medical team, individual differences of patients and unpredictable factors.
At the same time, the cycle of IVF may be affected by some unexpected circumstances, such as the inability to obtain enough eggs during egg retrieval, or the unsatisfactory embryonic development. These conditions may lead to cycle failure or the need for repeated surgery.
summary
The number of cycles required by IVF is uncertain, and the success rate of each cycle is difficult to ensure. Excellent hospitals and professional medical teams can provide better technology and services, thus increasing the success rate. Nevertheless, infertile couples need to have enough patience and confidence, and fully communicate and cooperate with doctors to improve the chances of success of IVF.
