is it true that sometimes, the egg moves towards the sperm, or just the egg makes more effort than we think, is not as passive as we think?
just asking, because it's based on new research articles that have been published lately, they say that the egg chooses the sperm, the sperm does not choose the egg, or that the egg does make some movement towards the sperm, I just wanted to make sure.

There's simply no real truth to this. Pituitary hormones guide the egg, not anything supernatural. The egg and sperm do not do any 'choosing' as you put it. They move with the help of the fimbria of the fallopian tubes guiding them down, if a viable sperm is there to meet the egg, that's the lucky one (or sometimes two) that fuse into this egg and start their journey forward. No selection going on...that's why there are sometimes birth defects and pregnancy ending circumstances. If the egg (or sperm) could actually pick/choose there would be zero birth defects.
