1. What are the causes of ovarian failure? Advanced age is the main reason for ovarian failure. After the age of forty, ovarian function declines very quickly, one year at a time, three years at a time! Patients of advanced age must seize the opportunity to retrieve eggs every month, we advocate continuous egg retrieval, not rest, three days of fishing and two days of sunbathing can not do great things, do not be delayed by Chinese medicine conditioning your precious opportunity! Surgical trauma is another important cause of ovarian failure. Especially now that laparoscopy is very popular, gynecological surgery is basically laparoscopic. Since laparoscopic suturing to stop bleeding is time-consuming and laborious, many doctors use electrocoagulation to stop bleeding, but the follicles in the ovaries are very sensitive to electrocoagulation and a large number of follicles are scalded to death, leading to ovarian failure. Tubectomy may also lead to ovarian failure due to destruction of ovarian blood vessels. Endometriosis, chronic pelvic inflammatory disease, pelvic radiotherapy, chemotherapy, immunosuppressants, etc. can destroy ovarian tissue or kill follicles in the ovaries, leading to ovarian failure. Unknown causes Genetic factors 2. Are there any medications to improve ovarian function? There are no medications to improve ovarian function. Ovarian decline is irreversible. Good eggs cannot be obtained with DHEA. In our clinical work, we found that most patients with high FSH will resume follicular development after lowering FSH with estrogen and progesterone, thus we proposed a new way of treating patients with ovarian failure: suppressing excessive FSH. In our clinical practice, we have found that after the development of the dominant follicle, some patients with ovarian failure also have small follicles, which are precious seeds. Our research has shown that after egg retrieval, if there are still small follicles of the right size, ovulation can be promoted again, which is our invention of secondary stimulation, known as the Shanghai method in international academic circles. We have also observed in our clinical work that once a patient with ovarian failure has had a successful ovulation stimulation, in the next menstrual cycle, ovarian function tends to improve, as evidenced by a decrease in FSH levels.
