What Is Vaginal Agenesis? A Plain-Language Guide to the Condition in Which the Vagina Doesn't Develop
Medically reviewed by Dr. Baraa Alnahhal, MD · Last reviewed: October 2026
TL;DR
Vaginal agenesis (pronounced a-JEN-uh-sis) is a rare disorder in which the vagina doesn't develop, and the womb (uterus) may only develop partially or not at all. The condition is present before birth and may also be associated with kidney or skeletal problems. It's also known as mullerian agenesis, mullerian aplasia, or Mayer-Rokitansky-Kuster-Hauser syndrome. Vaginal agenesis is often identified at puberty when a girl doesn't begin menstruating — even though her other signs of puberty develop typically. The good news is that treatment, most often a vaginal dilator used over time, is frequently successful in creating a vagina, and in some cases surgery may be needed. Treatment makes it possible to have vaginal intercourse.
Quick Answer
What is it? A rare condition present before birth in which the vagina doesn't develop and the uterus may only develop partially or not at all.
Other names: Mullerian agenesis, mullerian aplasia, or Mayer-Rokitansky-Kuster-Hauser syndrome.
How is it spotted? Usually at puberty when menstrual periods don't start, even though breasts and hair develop normally.
Why does it happen? Tubes called the mullerian ducts don't develop properly during the first 20 weeks of pregnancy.
How is it treated? Most often with a vaginal dilator used regularly over a few months; if that doesn't work, surgical options can create a functional vagina. Treatment makes vaginal intercourse possible.
What the research says
Dilation is a proven first step. A systematic review of 23 studies including 1,540 women with MRKH syndrome concluded that vaginal dilation is a viable initial treatment option, found limited evidence that “coital dilation” works as a method of dilation, and found that the literature supports psychological intervention to improve health and well-being. (Baby et al., J Adv Nurs, 2023)
Two common surgeries give similar results. A meta-analysis of 33 studies compared the laparoscopic Davydov and Vecchietti techniques. Mean neovaginal length at 12 months was 8.3 cm (95% CI 8.1 to 8.6) after Davydov and 8.7 cm (95% CI 7.2 to 10.3) after Vecchietti, and mean sexual function scores (FSFI) were 28.9 and 27.5, indicating no sexual dysfunction in either group. Operative time was much longer for Davydov (126 vs 40 minutes), and neither technique was superior in functional terms. (Martens et al., Fertil Steril, 2024)
Guidelines put dilation first and counseling alongside it. ACOG's committee opinion states that nonsurgical vaginal elongation by dilation should be the first-line approach, that all patients should be offered counseling and encouraged to connect with peer support groups, and that assisted reproduction with a gestational carrier has been shown to be successful for women with müllerian agenesis. (ACOG Committee Opinion No. 728, Obstet Gynecol, 2018)
What Is Vaginal Agenesis?
Vaginal agenesis (a-JEN-uh-sis) is a rare disorder in which the vagina doesn't develop, and the womb (uterus) may only develop partially or not at all. This condition is present before birth and may also be associated with kidney or skeletal problems.
The condition is also known as mullerian agenesis, mullerian aplasia, or Mayer-Rokitansky-Kuster-Hauser syndrome.
What Are the Signs of Vaginal Agenesis?
Vaginal agenesis often goes unnoticed until females reach their teens but don't menstruate (amenorrhea). Other signs of puberty usually follow typical female development. In other words, a girl with this condition goes through normal puberty in most visible ways — her breasts develop and she grows underarm and pubic hair — but her periods never start.
Vaginal agenesis may have these features:
Feature | What happens |
External genitals | The genitals look like a typical female |
The vagina | The vagina may be shortened without a cervix at the end, or absent and marked only by a slight indentation where a vaginal opening would typically be located |
The uterus | There may be no uterus or one that's only partially developed |
Monthly cramping | If there's tissue lining the uterus (endometrium), monthly cramping or chronic abdominal pain may occur |
The ovaries | The ovaries typically are fully developed and functional, but they may be in an unusual location in the abdomen |
Fallopian tubes | Sometimes the pair of tubes that eggs travel through to get from the ovaries to the uterus are absent or do not develop typically |
Because this condition can travel with other birth-related changes, vaginal agenesis may also be associated with problems with development of the kidneys and urinary tract, developmental changes in the bones of the spine, ribs, and wrists, hearing problems, and other congenital conditions that also involve the heart, gastrointestinal tract, and limb growth.
When Should You See a Doctor?
If you haven't had a menstrual period by age 15, see your health care provider.
What Causes Vaginal Agenesis?
It's not clear what causes vaginal agenesis, but at some point during the first 20 weeks of pregnancy, tubes called the mullerian ducts don't develop properly.
Typically, the lower portion of these ducts develops into the uterus and vagina, and the upper portion becomes the fallopian tubes. The underdevelopment of the mullerian ducts results in an absent or partially closed vagina, absent or partial uterus, or both.
Duct portion | What it normally becomes | What happens when it underdevelops |
Lower portion | The uterus and vagina | Absent or partially closed vagina, absent or partial uterus |
Upper portion | The fallopian tubes | Fallopian tubes absent or not developed typically |
What Are the Complications?
Vaginal agenesis may impact your sexual relationships, but after treatment, your vagina will typically function well for sexual activity.
Females with a missing or partially developed uterus can't get pregnant. If you have healthy ovaries, however, it may be possible to have a baby through in vitro fertilization. The embryo can be implanted in the uterus of another person to carry the pregnancy (gestational carrier). Discuss fertility options with your health care provider.
How Is Vaginal Agenesis Diagnosed?
Your pediatrician or gynecologist will diagnose vaginal agenesis based on your medical history and a physical exam.
Vaginal agenesis is typically diagnosed during puberty when your menstrual periods don't start, even after you've developed breasts and have underarm and pubic hair. Sometimes vaginal agenesis can be diagnosed at an earlier age during an evaluation for other problems or when parents or a doctor notice a baby has no vaginal opening.
Your health care provider may recommend testing, including:
Test | What it shows |
Blood tests | Assess your chromosomes and measure your hormone levels; they can confirm your diagnosis and rule out other conditions |
Ultrasound | Shows whether you have a uterus and ovaries and identifies if there are problems with your kidneys |
MRI | Gives a detailed picture of your reproductive tract and kidneys |
Other testing | May include tests to examine your hearing, heart, and skeleton |
How Is Vaginal Agenesis Treated?
Treatment for vaginal agenesis often occurs in the late teens or early 20s, but you may wait until you're older and you feel motivated and ready to participate in treatment.
You and your health care provider can discuss treatment options. Depending on your individual condition, options may involve no treatment or creating a vagina by self-dilation or surgery.
What Is Self-Dilation?
Self-dilation is typically recommended as the first option. Self-dilation may allow you to create a vagina without surgery. The goal is to lengthen the vagina to a size comfortable for sexual intercourse.
During self-dilation, you press a small, round rod (dilator) — similar to a firm tampon — against your skin at your vaginal opening or inside your existing vagina for 10 to 30 minutes 1 to 3 times a day. As the weeks go by, you switch to larger dilators. It may take a few months to get the result you want.
Discussion with your health care provider about the process matters, so that you know what to do and can talk about dilator options to find what works best for you. Using self-dilation at intervals recommended by your health care provider or having frequent sexual intercourse is needed over time to maintain the length of your vagina.
Some patients report problems with urinating and with vaginal bleeding and pain, especially in the beginning. Artificial lubrication and trying a different type of dilator may be helpful. Your skin stretches more easily after a warm bath, so that may be a good time for dilation.
Vaginal dilation through frequent intercourse is an option for self-dilation for women who have willing partners. If you'd like to give this method a try, talk to your health care provider about the best way to proceed.
What Are the Surgical Options?
If self-dilation doesn't work, surgery to create a functional vagina (vaginoplasty) may be an option.
Surgical option | How it works |
Tissue graft | The surgeon uses your own tissue — possible sources include skin from the outer thigh, buttocks, or lower abdomen. An incision creates the vaginal opening, the tissue graft is placed over a mold to create the vagina and placed in the newly formed canal, and the mold remains in place about one week |
Medical traction device | The surgeon places an olive-shaped device (Vecchietti procedure) or a balloon device (balloon vaginoplasty) at your vaginal opening. Using a thin, lighted viewing instrument (laparoscope) as a guide, the device is connected to a separate traction device on your lower abdomen or through your navel. You tighten the traction device every day, gradually pulling the device inward to create a vaginal canal over about a week |
Bowel vaginoplasty | The surgeon moves a portion of your colon to an opening in your genital area, creating a new vagina, then reconnects your remaining colon |
Aftercare differs by procedure. After a tissue graft, you generally keep the mold or a vaginal dilator in place — removable for bathroom use or sexual intercourse — and after the surgeon's recommended initial period, you use the dilator only at night. After a traction device is removed, you'll use a mold of varying sizes for about three months. After bowel vaginoplasty, you won't have to use a vaginal dilator every day, and you're less likely to need artificial lubrication for sexual intercourse.
After any surgery, use of a mold, dilation, or frequent sexual intercourse is needed to maintain a functional vagina. Health care providers usually delay surgical treatments until you feel prepared and able to handle self-dilation. Without regular dilation, the newly created vaginal canal can quickly narrow and shorten, so being emotionally mature and ready to comply with aftercare is critically important.
Talk to your health care provider about the best surgical option to meet your needs, and the risks and required care after surgery.
How Do People Cope With the Diagnosis?
Learning you have vaginal agenesis can be difficult. That's why your health care provider will recommend that a psychologist or social worker be part of your treatment team. These mental health providers can answer your questions and help you deal with some of the more difficult aspects of having vaginal agenesis, such as possible infertility.
You may prefer to connect with a support group of females who are going through the same thing. You may be able to find a support group online, or you can ask your health care provider if he or she knows of a group.
The Bottom Line
Vaginal agenesis is a rare condition present from before birth in which the vagina doesn't develop and the uterus may only develop partially or not at all — also known as mullerian agenesis, mullerian aplasia, or Mayer-Rokitansky-Kuster-Hauser syndrome. It usually comes to light at puberty, when a girl doesn't start her periods even though her breasts and hair develop normally, and it can travel with kidney, skeletal, hearing, and other congenital changes. The cause traces back to the mullerian ducts, tubes that should form the uterus, vagina, and fallopian tubes during the first 20 weeks of pregnancy, which fail to develop properly. The treatment path is hopeful: self-dilation with a dilator used a few times a day over a few months is the usual first step and is often successful on its own, and three surgical routes — tissue grafts, traction devices, or bowel vaginoplasty — can create a functional vagina when it isn't. After treatment, a vagina will typically function well for sexual activity, and for those without a functional uterus, in vitro fertilization with a gestational carrier may offer a path to parenthood for those with healthy ovaries. Support from mental health professionals and peer groups is a normal, expected part of care — not an optional extra. If you or someone you love hasn't had a period by age 15, seeing a health care provider is the right next step.
Take the Next Step
If you haven't had a menstrual period by age 15, see your health care provider — that's the key moment this condition typically surfaces. Before your appointment, make a list of your signs and symptoms and all the medications and supplements you take, and consider bringing a family member or friend along. Ask about the likely cause, what tests you may need, whether your condition is long lasting, what treatment options fit you, and whether you should see a specialist. If you receive a diagnosis, know that you're not alone: treatment makes it possible to have vaginal intercourse, and a psychologist, social worker, and support group can be part of your team from the start. If a vagina needs to be created, ask your provider to walk you through self-dilation first, and about the surgical options — tissue graft, traction device, or bowel vaginoplasty — and the aftercare each one requires.
Frequently Asked Questions
What is vaginal agenesis?
Vaginal agenesis is a rare disorder in which the vagina doesn't develop, and the uterus may only develop partially or not at all. It is present before birth and may also be associated with kidney or skeletal problems.
What are its other names?
Mullerian agenesis, mullerian aplasia, or Mayer-Rokitansky-Kuster-Hauser syndrome.
How do you know if you have it?
It often goes unnoticed until the teen years, when a girl doesn't begin menstruating even though her other signs of puberty develop typically. Sometimes it's diagnosed earlier when a doctor notices a baby has no vaginal opening. If you haven't had a menstrual period by age 15, see your health care provider.
Do the ovaries still work?
Yes, typically. The ovaries are usually fully developed and functional, though they may sit in an unusual location in the abdomen. Sometimes the fallopian tubes are absent or don't develop typically.
What causes it?
No one knows the exact cause, but at some point during the first 20 weeks of pregnancy, tubes called the mullerian ducts don't develop properly. The lower portion normally becomes the uterus and vagina; the upper portion becomes the fallopian tubes.
Can it affect other parts of the body?
Yes. It may be associated with kidney and urinary tract development problems, developmental changes in the spine, ribs, and wrists, hearing problems, and other congenital conditions involving the heart, gastrointestinal tract, and limb growth.
Can a person with vaginal agenesis get pregnant?
Females with a missing or partially developed uterus can't get pregnant. With healthy ovaries, however, it may be possible to have a baby through in vitro fertilization, with the embryo implanted in the uterus of a gestational carrier. Discuss fertility options with your provider.
What is the first treatment usually?
Self-dilation — pressing a small, round rod (dilator) against the vaginal opening or inside the existing vagina for 10 to 30 minutes, 1 to 3 times a day, switching to larger dilators over weeks, usually over a few months. It's often successful in creating a vagina without surgery.
What if self-dilation doesn't work?
Surgery to create a functional vagina (vaginoplasty) may be an option, using a tissue graft from your own skin, a medical traction device (Vecchietti or balloon vaginoplasty), or a portion of your colon (bowel vaginoplasty).
Will sex be possible after treatment?
Yes. Treatment makes it possible to have vaginal intercourse, and after treatment the vagina will typically function well for sexual activity. Ongoing dilation or frequent intercourse is needed to maintain a functional vagina after surgery.
What support is available?
Your provider will typically recommend a psychologist or social worker as part of your treatment team to help with difficult aspects such as possible infertility, and peer support groups — online or through your provider — are available for people going through the same thing.
