1.The most important preconception test for the father-to-be is semen examination. With the help of a doctor, a semen sample is collected to analyze the number, mobility and vitality of sperm to determine whether there is enough, high-quality sperm. It is more troublesome to take semen for examination by masturbation, and semen will not be examined during the usual physical examination. 2. If you haven’t had a physical examination for years or haven’t had a marriage test, it is also necessary to check for infectious diseases such as hepatitis, syphilis and AIDS. Compared to the fertility test and cost of the mother-to-be, the father-to-be test is much more convenient. Raising a healthy baby is a joint responsibility of both partners. The male partner should pay attention to caring and pampering the female partner throughout the preparation process, assist the female partner to better complete the task of pregnancy preparation, and read some parenting knowledge to be fully prepared to welcome the baby!
