Artificial insemination is a method in which sperm is deposited in the vagina of women through mechanical means replacing copulation, and near the time of ovulation. Thus, the journey to the fallopian tube is shortened, and therefore, the number of chances that more sperm approach the egg increases. The aim is to increase the chances of pregnancy in couples who have difficulty conceiving a child. The technique involves, firstly, to collect a semen sample that is treated in the laboratory to concentrate the sperm. The doctor inserts a speculum into the vagina to reach the cervix, and then injects the sperm into the uterus. Usually it's a little painful procedure and is usually accompanied by ovarian stimulation techniques.
