1. How ovulation promoting drugs improve the success rate of IVF
There are two kinds of ovulation promoting drugs: oral and injection. Clomiphene, gonadotropin and human chorionic gonadotropin are commonly used. These drugs can stimulate ovarian development and ovulation, increase the number and quality of eggs, and thus improve the success rate of IVF.

2. Influencing factors of IVF success rate
In addition to the use of ovulation promoting drugs, the success rate of IVF is also affected by many other factors. First of all, the age of the woman is one of the important factors that affect the success rate of IVF. The increase of female age will lead to the decrease of egg quality and quantity, thus reducing the success rate of IVF. Secondly, the quality and quantity of male sperm also have a certain impact on the success rate. In addition, the thickness and quality of the endometrium, the shape of the uterus, and the secretory function of endometrial glands are also closely related to the success rate of IVF.
In addition, the success rate of IVF is also affected by the technical level and equipment conditions of the hospital. Some large general hospitals and professional reproductive centers have rich experience and advanced equipment in the field of IVF, which can provide better treatment effect and service quality.

According to statistical data, the success rate of IVF is usually about 30% - 40% for women under 35 years old; For women over 35, the success rate will gradually decrease. Therefore, some couples may need to try IVF several times to get pregnant successfully.
