Which condition is characterized by painful intercourse and often linked to vaginismus?

The condition characterized by painful intercourse, often linked to vaginismus, is associated with pelvic floor dysfunction. Vaginismus is defined as an involuntary contraction of the pelvic floor muscles, making penetration painful or impossible. This muscle contraction can be caused by psychological factors, previous sexual trauma, or physical damage, and it leads to significant discomfort during intercourse.

Pelvic floor dysfunction encompasses a range of disorders that affect the muscles of the pelvic floor, including their ability to relax and function properly during sexual activity. When these muscles are overly tight or spasmodic, they can cause pain during intercourse, which is a key symptom of both vaginismus and broader pelvic floor issues.

In contrast, the other conditions listed, while they can cause pelvic pain or discomfort, do not specifically relate to the involuntary muscle contractions seen in vaginismus. Endometriosis involves the presence of endometrial-like tissue outside the uterus and can cause painful periods and intercourse, but it is distinct from the muscular issues occurring in pelvic floor dysfunction. Ovarian cysts may lead to pain in some cases but are not directly associated with painful intercourse. Pelvic inflammatory disease can cause discomfort and pain in the pelvic region, yet it doesn't specifically involve the pelvic muscle function that
