The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
The other group suggested that indeed there is a strong reason to believe that tilting the pelvis back, maybe even keeping the ankles elevated, and having a woman lie on her back for about 15 minutes with the pelvis positioned at about 20 degrees back is ideal for optimizing fertilization.

One group, the group that said, no, pelvic position doesn't really matter, don't worry about it, it's not going to influence the rates of fertilization, argued that the sperm swim very quickly and that if they are released near the cervix they're going to swim very quickly toward the egg in order to fertilize it regardless of pelvic position.
