Abstract

The American College of Obstetricians and Gynecologists makes the following recommendations and conclusions:

  • Patients with müllerian agenesis usually are identified when they are evaluated for primary amenorrhea with otherwise typical growth and pubertal development.
  • Rudimentary müllerian structures are found in 90% of patients with müllerian agenesis by magnetic resonance imaging. On ultrasonography, these rudimentary müllerian structures are difficult to interpret and may be particularly misleading before puberty.
  • Evaluation for associated congenital anomalies is essential because up to 53% of patients with müllerian agenesis have concomitant congenital malformations, especially of the urinary tract and skeleton.
  • All patients with müllerian agenesis should be offered counseling and encouraged to connect with peer support groups.
  • Future options for having children should be addressed with patients.
  • Primary vaginal elongation by dilation is the appropriate first-line approach in most patients because it is safer, patient-controlled, and more cost effective than surgery.
  • Because primary vaginal dilation is successful for more than 90–96% of patients, surgery should be reserved for the rare patient who is unsuccessful with primary dilator therapy or who prefers surgery after a thorough informed consent discussion with her gynecologic care provider and her respective parent(s) or guardian(s).
  • Regardless of the surgical technique chosen, referrals to centers with expertise should be offered. The surgeon must be experienced with the procedure because the initial procedure is more likely to succeed than follow-up procedures.
  • Although vulvar and vaginal intraepithelial neoplasia are possible, routine cytology testing is not regularly recommended because of the lack of a cervix.
  • Sexually active women with müllerian agenesis should be aware that they are at risk of sexually transmitted infections and, thus, condoms should be used for intercourse. Patients should be appropriately screened for sexually transmitted infections according to the guidelines for women without müllerian agenesis.
  • Patients should be given a written medical summary of their condition, including a summary of concomitant malformations. This information may be useful if the patient requires urgent medical care or emergency surgery by a health care provider unfamiliar with müllerian agenesis.
