Generally speaking, if the hospital has a reproductive department, both men and women can go directly to the reproductive department for preconception checkups; if not, the woman can go to the department of obstetrics and gynecology, and the man can go to the department of urology. Pre-conception checkups play an important role in eugenics and the health of both men and women. Men and women can go to the reproduction department of their local hospitals for checkups, depending on the classification of the hospital’s department. If the hospital does not have a fertility department, the woman can go to the obstetrics and gynecology department and the man to the urology department. Pre-conception checkups include a number of tests, such as blood and urine tests, electrocardiogram, thyroid function, liver and kidney function, special infectious diseases, as well as vaginal examination for women and semen examination for men, etc. Each of these tests has its own significance and can effectively prevent the transmission of physiological defects, hereditary diseases, etc. to the next generation. Therefore, it is recommended that couples who need to prepare for pregnancy should take the initiative to go to the hospital for pre-pregnancy checkups for the sake of the health of both parties as well as the next generation.
