1. A method of increasing pregnancy rates during embryo transfer using a sonography machine comprising:
(a) turning on the sonography machine;
(b) selecting a probe key from a probe selection menu;
(c) scanning a monitor for a 2D image to ascertain adequate distension of the urinary bladder and desired position of the uterus;
(d) adjusting settings for better visualization of the image;
(e) adjusting focal point and depth such that the focal point is at the endometrial cavity;
(f) changing the image from 2D to 3D4D;
(g) readjusting settings for optimal visualization of the image;
(h) determining the MIP point by visualizing the intra uterine cavity and calculating the intersection point of lines representing the axes of the fallopian tubes.
2. A method of embryo transfer during in vitro fertilization comprising:
(a) adjusting a 2D image on a sonography machine;
(b) passing a catheter through the cervical os;
(c) switching the image from 2D to 3D4D;
(d) adjusting settings for optimal visualization of the image;
(e) determining the MIP point within the uterine cavity;
(f) following the image of the catheter tip as it moves in the uterine cavity towards said MIP point; and
(g) releasing the embryo from the catheter once the catheter tip is over said MIP point.
