Artificial insemination is generally not very painful for the woman, there may be some discomfort, but not to the extent of pain. Before artificial insemination, it is usually necessary to take ovulation stimulation injections or ovulation stimulation drugs to let the follicles develop and mature, rupture and ovulate, and there may be dizziness, nausea and other discomforts after the use of the drugs, but it will not make the female partner feel very painful. On the day of artificial insemination, the man goes to the hospital to get semen, which is injected into the uterine cavity after being washed and processed in the laboratory. It is a relatively thin and soft artificial insemination catheter, which is injected directly into the uterus through the cervix, and the whole process will not be very painful either. In some patients, the operation of artificial insemination is more difficult, the artificial insemination tube can not enter the uterine cavity smoothly, and it is necessary to clamp the cervix or probe to expand the cervix, which will cause cervical discomfort, but it will not be particularly painful, and the woman can basically tolerate it. Each woman’s physical condition is different, and the feeling after IUI is also different.
