Aims To ask lots of questions and try to find the truth about the medicine-based effectiveness of letrozole (LE) combined with human menopausal gonadotropin (HMG) in the treatment of inability to have children crops patients with endocrine (things that are different from what is usually expected and the effect on ovulation-related chemicals produced by the body). Materials and Methods A total of 160 unable to have children crops patients with endocrine things that are different from what is usually expected who were treated in our hospital from March 2019 to March 2022 were selected as the subjects of this look at how things were in the past study and were divided into instance of watching, making a statement group was treated with human menopausal gonadotropin on the basis of the control group. The differences in serum related to the process of making children, chemical produced by the body levels, ovarian function, and ovulation induction effect between the two groups were watched and compared. Results After treatment, LH, FSH, PRL, and E2 in the observation group were better than those in the control group. The ovarian volume, follicle size, follicle diameter, and endometrial thickness of the two groups of patients were significantly improved, and the observation group was better than the control group. Significance is P < 0.05. After treatment, the ovarian volume, follicle size, follicle diameter, and endometrial thickness in the two groups were significantly improved, and the observation group was better than the control group, and the difference was statistically significant (P < 0.05). The ovulation rate, pregnancy rate, singleton pregnancy rate, and multiple pregnancy rate of the observation group were higher than those of the control group, and the difference was statistically significant by the chi-square test (P < 0.05). Conclusion Letrozole can promote the improvement of sex hormones in infertile patients. After being combined with human menopausal gonadotropin treatment, the follicle development and ovulation of patients are significantly improved, and infertility is improved to a certain extent. It has a certain reference value in the clinical treatment of endocrine abnormal infertility.
