How can normal menstruation not conceive children?

Female menstruation does not mean that the uterus is normal. If there are abnormal conditions such as uterine malformation and tubal blockage in women, it will cause infertility. If male testicular function is abnormal, male sperm abnormality rate is high, and sperm count is reduced, it will affect female pregnancy. Suggestion: Both husband and wife need to go to the hospital for pre-pregnancy examination to determine the cause of infertility before treatment.
