For women who have not had children after marriage, if they have been married for more than two years and have not had children, it cannot be excluded that infertility is the cause. It is necessary to go to the obstetrics and gynecology department of the local public hospital in time for laboratory tests of blood analysis, biochemical tests, urinalysis, laboratory tests of sex hormones, ultrasound examinations of the uterus and ovaries, internal gynecological examinations and, if necessary, anti-sperm antibody tests and chromosome-related laboratory tests to clarify the diagnosis of the disease. If everything is normal in female patients after examination, male infertility tests such as sperm motility test and sperm malformation test should be performed to clarify whether the condition of non-pregnancy is caused by male infertility factors. It is recommended to choose a local public hospital for the diagnosis and treatment of the disease.
