In case there has been no pregnancy, the couple should go to the hospital for a comprehensive examination to clarify the cause and then actively treat it. It is generally recommended for men to have a routine semen analysis to see if there are any problems with sperm quality and also to inform the doctor if there is sexual erectile dysfunction. It is recommended that women have blood tests for sex hormones, anti-Müllerian hormone, thyroid function, and infertility-related antibodies on an empty stomach on the 2nd-5th day of their menstrual period. In addition, women need to have a gynecological examination including routine vaginal discharge and bacterial culture of the discharge on 3 days after menstruation without intercourse, as well as an ultrasound on day 10 of the menstrual cycle to monitor the growth and development of the follicles and, if necessary, a hysterosalpingogram to see if the fallopian tubes are blocked. If there is no dominant follicle or normal ovulation, it will also affect the pregnancy. If the above tests are normal but both partners are still not pregnant, you can consult with the eugenics department to see if there is any immune infertility. If you have not been preparing for pregnancy for more than one year, infertility cannot be diagnosed and it is best for women to have ultrasound to monitor ovulation during ovulation and wait for natural conception. During the preparation period both partners should pay attention to reduce their own mental stress, have a regular sex life, which can be maintained at an average frequency of 2 times a week, have a light diet, and stop smoking and drinking. If the couple has abnormal problems in the examination and conventional treatment is not effective, assisted reproduction techniques can be used to help conception. In particular, if the male is found to have infertility problems and not very serious deformed sperm, artificial insemination can be used to inject “screened” sperm into the female reproductive tract for the purpose of conceiving a woman. If the inability to conceive is due to the female partner, IVF can be used to remove the woman’s eggs and fertilize them in an embryo lab to form a fertilized egg that can then be delivered to the woman’s uterus for conception.
