Both men and women can apply for the birth permit, but in principle, it is handled by the woman, because only the family planning department where the woman's household registration is located holds the information of the woman's various fertility services, which will be easier to handle and more difficult for the man. Generally speaking, both men and women should be present when applying for a birth permit. Just take their household registration book, ID card and marriage certificate to the family planning department where either of you is registered. There is generally no need to provide proof of infertility. Besides, it's your first time to get married. The woman wants to do gynecological examination mainly to see if there are serious gynecological diseases that affect pregnancy and childbirth, whether she is pregnant or not, and then take blood samples from both men and women for inspection (as if to screen diseases that pose a serious threat to the health of children born later). I won't tell you whether it is normal or not after the test, but I will tell you whether it is abnormal, but please rest assured that more than 90% of them are normal. It takes a period of time, about a month, from submitting a birth application to obtaining a birth permit, and the situation varies from place to place.
