We all know that the IVF treatment cycle is relatively long, generally about 25-30 days, during which many processes need to be passed, each of which needs to be rigorously and meticulously operated to avoid the failure of the entire IVF treatment due to the error of a certain link. Therefore, there are many problems in the IVF process that need to be paid attention to by patient friends.
Hengjian Overseas said that the so-called details determine success or failure, this sentence is very appropriate to use in IVF fertility, as we all know, the success rate of IVF is affected by many factors, among them, the factors that affect the success rate in the IVF process are the most. So, what factors affect the success rate of IVF?
What factors affect success rates during IVF?
1. Age
A woman's age is a key factor in the success of IVF. When a woman is over 35 years old, her ovarian function declines, the quality and quantity of eggs declines, and the success rate is greatly reduced. Male age also affects the success rate of IVF, mainly in terms of the difference in sperm quality, but much lower than the impact of female age on IVF success rate.
2. Causes of infertility
Female factors such as primary infertility, severe endometriosis with severe uterine malformations, polycystic ovary syndrome, or severe hypospermia, azoospermia, or the presence of a large number of deformities, the success rate of IVF will be low. But with the advent of the second generation of IVF technology, the impact of male semen-induced infertility on IVF success rates will be reduced.
3. Ovarian function
The ovaries are the place where eggs are produced, the ovarian function is good, the better the quality of the eggs discharged, on the contrary, the poor ovarian function, the quality of the eggs will decline, the pregnancy and miscarriage rate of women will increase, and the decline of ovarian function is not only directly related to age, but also has a large difference in physical fitness between individuals.
4. Embryo quality
High-quality embryos are easy to succeed, inferior embryos have a high failure rate, and high-quality embryos are important conditions for success. According to the six-level grading method of embryos: fresh embryos are available for transfer from grade I to IV. grades, and grades I and II are excellent embryos.
5. Uterine membrane environment
Endometrium is the most important place for embryos to implant, if the endometrium is thick enough, the blood flow is rich and the cells divide well, it will increase the implantation rate of the embryo, while the endometrium is too thin, the blood flow is insufficient, and the endometrium of the hormone secretion is lacking, the embryo is not easy to implant. At the same time, uterine diseases such as endometrial damage and uterine myadenopathy may cause the embryo to fail to implant and affect the success rate.
6. Chromosomes
The proportion of chromosomal abnormalities in infertility is not high, but it is still present, and couples with chromosomal problems have a higher normal pregnancy rate and miscarriage rate, and for this situation, these abnormal factors need to be eliminated with the help of third-generation IVF screening diagnostic technology to improve the success rate of IVF.
7. Psychological state
The influence of mental state is also extremely critical, and the patient's psychological and mental state is a very important factor affecting the success or failure of IVF treatment. Excessive psychological tension is easy to cause endocrine disorders, resulting in difficulty for embryos to implant, so infertile women should maintain psychological balance and be optimistic and open-minded during the IVF process.
Hengjian overseas tips: The above is a few aspects of the IVF process that affect the success rate, I hope to give you a reference role. Every link in the test tube process should be careful and cautious, but do not put too much pressure on yourself, so as not to cause psychological burdens, and maintain a peaceful state of mind.
