Sperm needs to be ejaculated once about three days before the artificial insemination procedure. The main purpose of sperm discharge before artificial insemination is to ensure the quality of sperm, because if you don’t ejaculate for a long time or ejaculate too often, it will lead to high rate of sperm immaturity and deformity or low quality of sperm, which will affect the success rate of artificial insemination. Men can return to the normal state of sperm about three days after normal ejaculation, so it is better to ejaculate once three days before artificial insemination. Normally, you need to exercise more, quit smoking and drinking, don’t sit for a long time, and don’t wear too tight pants or underwear, so as to keep the air permeability of the genitals can also improve the quality of sperm. In addition, it is important to note that artificial insemination requires sperm quality monitoring under the arrangement of the doctor. If there is any abnormality in sperm quality, early intervention can be made.
