In the absence of contraception, not getting pregnant within a year is called infertility. If you don’t get pregnant in six months, you can relax and continue to prepare for pregnancy; or the couple can go to the hospital to do relevant examinations to clarify the cause, such as semen laboratory tests for men and sex hormone six, ultrasound, leukorrhea routine and other tests for women, to clarify whether there is any disease in the body. Routine semen test is relatively simple, men can abstain from sex for 5-7 days before the test, and then semen can be retained to clarify whether the sperm is normal or not through laboratory tests. The female side of the examination is relatively more, as follows: 1, sex hormone six: to check whether the female endocrine system is normal; 2, ultrasound: to monitor whether the follicle development is good; 3, leukorrhea routine: to understand whether there are gynecological inflammatory problems; 4, tubal iodine oil imaging: to check whether the fallopian tubes are smooth; 5, hysteroscopy, laparoscopy: to clarify whether there is any disease of the reproductive system. If the couple does not have any physical abnormalities, it is recommended to maintain sufficient sleep, moderate exercise, a stable mindset, and continue to prepare for pregnancy. If the couple is still not pregnant after half a year, if it is found that the pregnancy is caused by poor sperm vitality, ovulation disorders and other disease factors, it is necessary to carry out symptomatic treatment for the disease first, and if the treatment effect is not good, it is possible to conceive through the method of in vitro fertilization.
