As a newly formed family, it is obviously not superfluous for a young couple to go to the hospital for a prenatal or preconception checkup before they plan to have a baby. Why are we talking about pre-breeding or pre-pregnancy tests here? First of all, let me give young couples a bit of common sense. Why is it “prenatal checkup” rather than “preconception checkup” for men? Because with the rapid development of the emerging discipline of male science, which is gradually being recognized and accepted by everyone, some traditional concepts are also changing. In the field of male science, professionals agree that the process of pregnancy is mainly done by the woman, infertility is mainly for women, for men, infertility is obviously more scientific than infertility, more targeted. Male prenatal examination mainly includes the following aspects: 1, physical examination: commonly known as a male doctor to touch, touch the content is mainly the development of male reproductive organs. Understand the development of reproductive organs, there is no deformity or disease, the most important is to observe the development of the penis, testicular volume size (because generally speaking, the larger the volume of the testicles, the better the spermatogenic function, and vice versa, the worse), epididymis whether there is a cyst, whether the lack of vas deferens, spermatic vein varicose, and so on. So don’t underestimate this touch, sometimes the value of this touch is higher than tens of thousands of dollars of medicine and injections. 2, laboratory tests: here is to refer to everyone knows the blood test, and we are not familiar with the male semen and secretions of the examination. Blood is mainly to check whether there are infectious diseases, blood, liver and kidney function, TORCH; body fluids, including semen tests and mycoplasma, chlamydia. Here to mention in particular, men must pay attention to the semen test before the last ejaculation 2-7 days after the hospital test. In the clinic, there are many young couples to the hospital after queuing, registration, consultation, it is not easy to see the doctor’s turn, the results of the semen can not be checked, the reason is that I do not know the semen test time requirements. 3, common sense pregnancy preparation: here to talk about a little common sense pregnancy preparation, women only once a month the opportunity to ovulate, couples only in the ovulation period coitus only have the opportunity to get pregnant, so male friends must grasp the opportunity. Female friends should know that when preparing for pregnancy, 3 months before and after pregnancy is required to take oral folic acid.
