The turkey baster method is a slang term for self or at-home insemination. The name comes from the idea that the syringe or other tool used in the procedure resembles a turkey baster. An actual turkey baster is much too large to effectively handle a small semen sample.
The turkey baster method is also known as self-insemination or at-home insemination.
FertilitySmarts explains Turkey Baster Method
During at-home insemination, a syringe or similar tool is used to draw up semen and insert it inside a woman's vagina. Because fluid is drawn up from one end and then released, the image has been associated with a turkey baster. This is how the turkey baster method got its name.
The turkey baster method (self-insemination) is actually most commonly performed using an insemination syringe. In order to potentially produce a pregnancy, it is important that the timing of this procedure coincides with the time in a woman's cycle when she is ovulating.
