Congenital Absence of the Vagina (Vaginal Agenesis)

What is Vaginal Agenesis?

Congenital absence of the vagina (vaginal agenesis) is a rare condition where the uterus and vagina do not form genetically. Patients may have no vagina and uterus, or these structures may be underdeveloped. In some cases, the uterine tissue may be present in small amounts, causing increased abdominal pain during menstruation even though there is no vaginal bleeding.

Since the ovaries develop from a different region, they can be located within the abdomen. Patients with vaginal agenesis may also have additional conditions such as dual urinary systems or abnormal kidney positions, so they need to be monitored for other potential issues. Additionally, skeletal system disorders may be present. A full system examination is advisable.

What Are Congenital Vaginal Defects?

Vaginal agenesis, where there is no vaginal space,
A septum (partition) between vaginal walls,
Absence of the upper 1/3 of the vagina, which may result in the uterus being present but no connection, leading to a blind ending and the vagina appearing shorter than expected.

Müllerian Agenesis

Müllerian agenesis refers to the congenital absence of the uterus, cervix, and vagina due to the failure of the Müllerian duct to develop. This condition is characterized by the absence of the uterus, cervix, and vagina.

Rokitansky-Küster-Mayer Syndrome

This is a rare condition that affects 1 in 4,000 to 1 in 10,000 individuals. It is characterized by the absence of the uterus, cervix, and vaginal structures due to Müllerian agenesis, along with kidney and urinary tract abnormalities, and sometimes skeletal system issues. The ovaries may be present because they develop from a different embryonic origin.

Does Congenital Absence of the Vagina Affect Motherhood?

In patients with vaginal agenesis, pregnancy is not possible because the uterus may be rudimentary or absent. However, it is possible with a uterus transplant. While legal restrictions prevent this in the country, patients with ovaries may have the option to have children through surrogacy abroad.

Does Congenital Absence of the Vagina Affect Sexual Intercourse?

Since there is no vagina in patients with vaginal agenesis, sexual intercourse is not possible. If a rudimentary vaginal structure exists, usually 1-2 cm in length, intercourse is also not feasible. The goal of vaginal agenesis surgery is to enable healthy sexual intercourse.

Symptoms of Congenital Absence of the Vagina

In patients with vaginal agenesis, the absence of menstruation by the age of 15-16, or intermittent abdominal pain during menstrual cycles (if a rudimentary uterus is present) due to accumulation of menstrual blood, can occur. These patients may also experience difficulty with sexual intercourse. Additionally, urinary tract abnormalities can lead to recurrent urinary tract infections.

What Causes Vaginal Agenesis?

Congenital absence of the vagina occurs due to the failure of the Müllerian duct to form during embryonic development. This rare condition is believed to result from genetic factors or developmental disruptions in the womb.

How is Vaginal Agenesis Diagnosed?

In adolescents, vaginal agenesis is suspected in cases where:

Breast and hair development occur, but menstruation is absent, or there is intermittent pain during the menstrual cycle,
There is no vaginal opening,
Difficulty engaging in sexual intercourse in early adulthood,
There are additional urinary tract issues.

A gynecological examination will reveal the absence of the vagina, and ultrasound should be used to confirm the absence of the uterus. Additionally, kidneys and urinary tract should be checked via ultrasound and IVP. The presence and location of the ovaries should also be assessed.

Treatment for Congenital Absence of the Vagina

The treatment for vaginal agenesis is typically surgical. In selected cases where the vaginal rudiment is small, vaginal dilation using penile prostheses (vaginal dilators) can systematically open the vaginal space. This treatment is lengthy and requires patience but is considered a safe approach.

Vaginal dilators are applied starting from larger sizes to smaller ones, with creams that prevent tissue damage. For this process, the patient's psychological readiness and being over 18 years old are important. If this process is not completed, tissue stiffening may occur, and restarting could cause difficulties.

Another method is to surgically create a vaginal space using perianal tissue (skin tissue where the vaginal space should be) to form the vaginal cavity, followed by gradual dilation with vaginal dilators. This approach is considered safer and has a lower complication rate than the method involving the colon for vaginal creation. Gynecologists prefer the perianal approach for its safety.

A piece of the sigmoid colon (from the intestine) can also be used to cover the surgically created vaginal space, placed between the anus and bladder. This procedure, called neo-vagina, involves using the sigmoid colon purely as a covering, not for intestinal passage. It carries higher risks of complications and infection compared to vaginal dilator methods and should only be used in selected cases.

Recovery After Vaginal Agenesis Surgery

After surgery for congenital absence of the vagina, recovery is relatively quick, but reaching the desired vaginal space with vaginal dilators takes time. Tissue formation in the newly created vaginal space also requires a process. It should be understood that with minimal surgical risk, this procedure, combined with exercises, can successfully achieve the desired vaginal opening. The purpose of this procedure is to enable the patient to engage in sexual intercourse.

Can Sexual Intercourse Be Resumed After Vaginal Agenesis Surgery?

The goal of vaginal agenesis surgery is to enable the patient to engage in sexual intercourse. Properly performed surgery and the gradual use of vaginal dilators help achieve the desired vaginal opening.

Can Sexual Pleasure Be Experienced After Vaginal Agenesis Surgery?

Sexual pleasure is transmitted through nerves to the pelvic floor, particularly through the pudendal nerves located in the clitoral area. Once the desired vaginal space is created, clitoral orgasm and sexual pleasure become possible.
