Do sexual positions affect fertility?

Sexual positions do not significantly impact fertility in terms of conception rates; however, some practices can be considered to potentially enhance the chances of successful fertilization. According to Andrew Huberman, there is a general belief or "lore" rather than scientific evidence that supports specific sexual positions affecting fertility. He notes that variables affecting conception, such as sperm volume and its motility, are numerous and challenging to control in different sexual activities 1.

Additionally, Huberman suggests that after ejaculation, if the female partner adjusts her pelvis slightly, about 15 degrees upwards, and avoids standing immediately, it might help in keeping the semen from leaking out too quickly, potentially increasing the chances for successful sperm-egg interaction. This adjustment, while not scientifically proven for improving fertility, is often recommended as a practical tip by some fertility specialists 1.
