What are the influencing factors of IVF success rate?
IVF technology is a kind of assisted reproductive technology, which can help those couples who cannot conceive naturally realize their reproductive aspirations. However, the success rate of IVF is not static and is affected by many factors. These influencing factors will be elaborated from four aspects as follows.
Age of the woman
The age of the woman is one of the important factors affecting the success rate of IVF. Women's reproductive capacity will decrease with age, so young women are more likely to successfully conceive and give birth. According to the data of Fudan University Affiliated Obstetrics and Gynecology Hospital, the success rate of IVF for women under 35 years old is more than 50%, while that for women over 40 years old is only about 20%. Therefore, choosing the right age for IVF can significantly improve the success rate.
Moreover, the quality of female eggs is also one of the factors affecting the success rate of IVF. With the growth of age, the number and quality of female eggs will decline, which will reduce the success rate of fertilization and implantation. For women over 35 years of age, it may be a more appropriate choice to select their eggs for IVF, so as to improve the success rate.
Male sperm quality
The quality of the man's sperm will also affect the success rate of IVF. The quantity, shape and vitality of sperm are important indicators for evaluating sperm quality. If the man has insufficient sperm, abnormal sperm or low vitality, the success rate of IVF will be reduced. If the quality of the man's sperm is not ideal, he can choose to carry out selective sperm injection or ICSI technology to improve the success rate of fertilization.
Living habits and physical conditions
Life habits and physical conditions will also affect the success rate of IVF. Smoking, drinking and using certain drugs will damage the reproductive system and reduce the success rate of fertilization and implantation. Therefore, couples should try to improve their living habits, quit smoking and limit alcohol intake before IVF.
In addition, physical condition will also affect the success rate of IVF. If women suffer from diabetes, thyroid problems, polycystic ovary syndrome and other diseases, or have problems such as uterine cavity malformations and uterine fibroids, the success rate of IVF will be reduced. Before IVF, couples should receive a comprehensive physical examination to ensure that they are in good health.
Hospital technology and doctor experience
The technical level of hospitals and the experience of doctors are also important factors affecting the success rate of IVF. IVF requires multiple steps, including egg collection, sperm processing, embryo culture and embryo transfer. If the hospital's technical equipment is advanced and the doctors are experienced and can skillfully operate each step, the success rate of IVF will be higher.
In conclusion, the success rate of IVF is affected by many factors. The age of the woman, the quality of the man's sperm, the couple's living habits and physical conditions, as well as the hospital's technology and doctor's experience are all important factors affecting the success rate. Choosing an appropriate age, improving living habits, maintaining good physical conditions, and accepting IVF technology in professional hospitals can significantly improve the success rate of IVF.
