There is not enough research to know if any of these medicines help relieve CPP symptoms.

Hormonal contraceptives (birth control), hormone shots, and medicines that act like hormones.

There is not enough research to know if any other hormonal therapies help relieve CPP symptoms.

In one study, women with endometriosis who took a hormone-like medicine called raloxifene (Evista^®) after having a diagnostic laparoscopy had their pain return quicker than women who did not take any medicine.

In one study, women who took a hormone-like medicine called depot leuprolide (Lupron Depot^®) felt less pain than women who did not take any medicine. Most of the women in the study had endometriosis.

Laparoscopic adhesiolysis (pronounced ad-HEES-ee-oh-lye-sis): scar tissue is removed in and around your bowel.

LUNA (laparoscopic utero-sacral nerve ablation): some of the nerves in or around your uterus are destroyed.

Utero-sacral ligament resection: some of the nerves and tissue around the uterus are removed.

Hysterectomy: a surgeon removes all or part of your uterus and ovaries.

A few studies showed that removing scar tissue through a laparoscope (called “laproscopic adhesiolysis”) had no effect on relieving pelvic pain or improving the quality of a woman’s life.

A few studies showed that LUNA did not help pelvic pain any more than having a diagnostic laparoscopy.

There is not enough evidence to know how well utero-sacral ligament resection or hysterectomy work to help relieve CPP symptoms.
