The causes of infertility are extremely numerous, and in general, infertility caused unilaterally by the wife accounts for 50%, unilaterally by the man for 30%, and jointly by both partners for 20%. Under normal physiological conditions, a couple living together without contraception and having a normal sex life has a 20% chance of conceiving every month, a 70% chance of getting pregnant in six months and an 80% chance of getting pregnant in a year. If more than a year without contraception and infertility is medically known as infertility, medical examination should be carried out, that is to say, a couple what fertility problems are not any month want to get pregnant can be as desired, but if you marry later, older, want to rush to get pregnant, you can advance to six months after marriage to carry out the relevant examination. Because people have their own strengths and weaknesses, and specialize in their professions, you can only get the best medical help and achieve the best medical results and minimize medical damage if you find the doctor who has the most professional knowledge and skills in diagnosing the disease you are suffering from. A doctor’s treatment is all about diagnosis! If the diagnosis is not clear, the treatment will not work! Only the correct choice of professional doctors can ultimately make their own disease to get the correct and appropriate good treatment. Checking the husband first is simple and economical: Some people think that the reason for not having children is definitely the woman, so they always check the woman around. In fact, the causes of infertility are extremely numerous, generally speaking, infertility caused unilaterally by the wife accounts for 50%, the male unilateral causes account for 30%, and the common causes of both parties account for 20%. The male fertility test is simple and convenient, painless, non-invasive and less costly, so the infertility test will first check whether the male internal and external genitalia are developing normally, and if there is no abnormality in the genital fertility test and the sexual function is normal, the next step is to do a semen test on the male side. If the semen examination is normal, basically we can rule out the possibility of infertility caused by the male partner, and then we can start looking for the cause from the female partner. 1, find out the husband’s inability to produce sperm, no need to check the wife again If the semen examination results are spermless, the next step is to do a testicular biopsy. If the testicular biopsy result is no sperm production ability, it means that the male partner is not fertile and does not need to continue to do other tests. If there is sperm in the testis, the vas deferens may be blocked and a vasectomy may be performed. 2, the female side of the examination follows the “progressive, demining method” for the first visit, do a general gynecological examination to see if there are reproductive organ abnormalities and gynecological diseases such as vaginitis, uterine tumors. If there is any disease, treat it before seeing if you can get pregnant. Examination of the fallopian tubes: If the previous gynecological examinations are normal, an X-ray hysterosalpingogram should be done 3-7 days after menstruation to confirm whether the uterine cavity is normal and whether the fallopian tubes are open. If the fallopian tubes are normal, women can check ovulation to see if the follicles are developing normally; if the menstruation is not normal, ovulation is generally not good, so blood can be drawn directly to check endocrine hormones. These are the main items to check. If the previous tests do not find any problem, then we can check the anti-endometrial antibody, anti-sperm antibody, and chromosome test. Laparoscopy is the last test. If you have been trying to conceive for more than five years and have not been able to detect any fertility problems through various fertility tests, you can try this method.
