How do you know that you insert the straw in the proper location in the cervix?

To ensure the straw is inserted in the proper location in the cervix, it is important to follow established protocols and guidelines specific to the procedure being performed, such as artificial insemination or embryo transfer. Typically, proper placement is confirmed by gently feeling for the cervical opening and guiding the straw into the cervical canal. Additionally, using appropriate visualization techniques, such as ultrasound, can help verify the correct positioning. Proper training and experience are essential for achieving accurate placement.
