In a gynecology practice, it is standard practice for the examination table to be equipped with stirrups in which the patient rests her heels. If she is properly positioned with her buttocks at the edge of the seat, access is easy for examinations or procedures on the genital area.
In recent years, obstetricians, who primarily care for pregnant women, seem to prefer a knee support system, which is considered more comfortable. In a general practitioner's office, the examination couch rarely has a removable leg rest, and stirrups are an option that is not commonly used. In this case, the doctor asks the patient to adopt the so-called "frog" position, with her legs apart and her feet flat on the sides.
In the 2010s, an alternative emerged with what is known in France as the "English" (or Sims) position. The woman lies on her side with one leg bent in front of her, and the doctor is positioned behind her.
This position doesn't complicate access to the vulva and vagina, and all necessary procedures can be performed (including IUD insertion). Personally, I think it slightly complicates the relationship between the practitioner and the patient. The patient presents her buttocks and may be less relaxed, not being in control of what is happening. However, in the classic stirrup position, she can see her gynecologist, who can also observe her facial reactions. In my opinion, it's very important to be able to assess the patient's level of stress (or pain) when performing a procedure in her most intimate area.
