Vaginal hypoplasia is the underdevelopment or incomplete development of the vagina. Vaginal hypoplasia can vary in severity from being smaller than normal to being completely absent. The absence of a vagina is a result of vaginal agenesis. Diagnostically, it may look similar to a vaginal obstruction. It is frequently associated with Mayer-Rokitansky-Küstner-Hauser (MRKH) syndrome, in which the most common result is an absent uterus in conjunction with a deformed or missing vagina, despite the presence of normal ovaries and normal external genitalia. It is also associated with cervical agenesis, in which the uterus is present but the uterine cervix is absent.

The presence of unusual lumps in the wall or base of the vagina is always abnormal. The most common of these is Bartholin's cyst. The cyst, which can feel like a pea, is formed by a blockage in glands which normally supply the opening of the vagina. This condition is easily treated with minor surgery or silver nitrate. Other less common causes of small lumps or vesicles are herpes simplex. They are usually multiple and very painful with a clear fluid leaving a crust. They may be associated with generalized swelling and are very tender. Lumps associated with cancer of the vaginal wall are very rare and the average age of onset is seventy years. The most common form is squamous cell carcinoma, then cancer of the glands or adenocarcinoma and finally, and even more rarely, melanoma.

Genital symptoms include dryness, itching, burning, soreness, pressure, white discharge, malodorous discharge due to infection, painful sexual intercourse, bleeding after intercourse. In addition, sores and cracks may occur spontaneously. Atrophic vaginitis is one possible cause of postmenopausal bleeding (PMB).

Urinary symptoms include painful urination, blood in the urine, increased frequency of urination, incontinence, and increased likelihood and occurrence of infections.

Atrophic vaginitis (also known as vaginal atrophy, vulvovaginal atrophy, or urogenital atrophy) is an inflammation of the vagina (and the outer urinary tract) due to the thinning and shrinking of the tissues, as well as decreased lubrication. These symptoms are due to a lack of the reproductive hormone estrogen.

The most common cause of vaginal atrophy is the decrease in estrogen which happens naturally during perimenopause, and increasingly so in post-menopause. However this condition can occur in other circumstances that result in decreased estrogen such as breastfeeding and the use of medications intended to decrease estrogen too, for example, treat endometriosis.

The symptoms can include vaginal soreness and itching, as well as painful intercourse, and bleeding after sexual intercourse. The shrinkage of the tissues and loss of flexibility can be extreme enough to make intercourse impossible.

Symptoms and signs in the newborn can be sepsis, abdominal mass, and respiratory distress. Other abdominopelvic or perineal congenital anomalies frequently prompt radiographic evaluation in the newborn, resulting in a diagnosis of coincident vaginal atresia. Symptoms for vaginal atresia include cyclical abdominal pain, the inability to start having menstrual cycles, a small pouch or dimple where a vaginal opening should be, and pelvic mass when the upper vagina becomes filled with menstrual blood. Signs and symptoms of vaginal atresia or vaginal agenesis can often go unnoticed in females until they reach the age of menstruation. Women may also experience some form of abdominal pain or cramping.

The absence of a vagina is a result of vaginal agenesis. Diagnostically, it may look similar to a vaginal obstruction such as can be caused by an imperforate hymen or, less commonly, a transverse vaginal septum.

It is frequently associated with Mayer-Rokitansky-Küstner-Hauser (MRKH) syndrome, in which the most common result is an absent uterus in conjunction with a deformed or missing vagina, despite the presence of normal ovaries and normal external genitalia. It is also associated with cervical agenesis, in which the uterus is present but the uterine cervix is absent.

The situation is most urgent where there is a menstruating uterus with an obstructed uterovaginal outflow, leading to hematometra. In this case prompt medical action is required.

Vaginal atresia can sometimes be diagnosed by physical examination soon after birth. A child with vaginal atresia often has other congenital abnormalities and other tests such as x-ray and tests to evaluate the kidney are done. Findings in adolescents may include abdominal pain, difficulty voiding, and backache, but most present with amenorrhea. Difficulties with sexual intercourse can suggest atresia. In the event that the condition is not caught shortly after birth, vaginal atresia becomes more evident when no menstrual cycle is occurs. If vaginal atresia is suspected by the doctor, a blood test may also be request for any of the previously mentioned syndromes, a magnetic resonance imaging (MRI) test, or an ultrasound. A regular evaluation of children born with an imperforate anus or anorectal malformation should be paired with the assessment of the results from these tests.

Vaginal hypoplasia can vary in severity from being smaller than normal to being completely absent.

Vaginal discharge is a mixture of liquid, cells, and bacteria that lubricates and protects the vagina. This mixture is constantly produced by the cells of the vagina and cervix and it exits the body through the vaginal opening. The composition, amount, and quality of discharge varies between individuals as well as through the various stages of sexual and reproductive development. Normal vaginal discharge may have a thinner, watery consistency or a thick, sticky consistency, and may be clear or white in color. Normal vaginal discharge may be large in volume but typically does not have a strong odor, nor is it typically associated with itching or pain. While most discharge represents normal functioning of the body, some changes in discharge can reflect infection or other pathological processes. Infections that may cause changes in vaginal discharge include vaginal yeast infections, bacterial vaginosis, and sexually transmitted infections. The characteristics of abnormal vaginal discharge vary depending on the cause, but common features include a change in color, a foul odor, and associated symptoms such as itching, burning, pelvic pain, or pain during sexual intercourse.

Foreign objects can cause a chronic vaginal discharge with a foul odor. Common foreign objects found in adolescents and adults are tampons, toilet paper, and objects used for sexual arousal.

A vaginal septum is a congenital partition within the vagina; such a septum could be either longitudinal or transverse.

Leukorrhea or (leucorrhoea British English) is a thick, whitish or yellowish vaginal discharge. There are many causes of leukorrhea, the usual one being estrogen imbalance. The amount of discharge may increase due to vaginal infection or STDs, and it may disappear and reappear from time to time. This discharge can keep occurring for years, in which case it becomes more yellow and foul-smelling. It is usually a non-pathological symptom secondary to inflammatory conditions of vagina or cervix.

Leukorrhea can be confirmed by finding >10 WBC under a microscope when examining vaginal fluid.

Vaginal discharge is not abnormal, and causes of change in discharge include infection, malignancy, and hormonal changes. It sometimes occurs before a girl has her first period, and is considered a sign of puberty.

Hematometra typically presents as cyclic, cramping pain in the midline of the pelvis or lower abdomen. Patients may also report urinary frequency and urinary retention. Premenopausal women with hematometra often experience abnormal vaginal bleeding, including dysmenorrhea (pain during menstruation) or amenorrhea (lack of menstruation), while postmenopausal women are more likely to be asymptomatic. Due to the accumulation of blood in the uterus, patients may develop low blood pressure or a vasovagal response. When palpated, the uterus will typically feel firm and enlarged.

A longitudinal vaginal septum develops during embryogenesis when there is an incomplete fusion of the lower parts of the two Müllerian ducts. As a result, there is a "double vagina". There may be associated duplications of the more cranial parts of the Müllerian derivatives, a double cervix, and either a uterine septum or uterus didelphys (double uterus).

The person with a longitudinal vaginal septum may be asymptomatic and not aware of the condition. If dyspareunia is a problem a simple resection of the septum could be performed.

Vaginal flatulence is an emission or expulsion of air from the vagina. It may occur during or after sexual intercourse or during other sexual acts, stretching or exercise. The sound is somewhat comparable to flatulence from the anus but does not involve waste gases and thus often does not have a specific odor associated. Slang terms for vaginal flatulence include vart, queef, and fanny fart (mostly British).

Vaginal gas that involves strong odor or fecal matter may be a result of colovaginal fistula, a serious condition involving a tear between the vagina and colon, which can result from surgery, child birth, diseases (such as Crohn's disease), and other causes. This condition can lead to urinary tract infection and other complications. Vaginal gas can also be a symptom of an internal female genital prolapse, a condition most often caused by childbirth.

Puffs or small amounts of air passed into the vaginal cavity during cunnilingus will not cause any known issues, however "forcing" or purposely blowing air at force into the vaginal cavity can cause an air embolism, which in very rare cases can be potentially dangerous for the woman, and if pregnant, for the fetus.

Common symptoms include increased vaginal discharge that usually smells like fish. The discharge is often white or gray in color. There may be burning with urination. Occasionally, there may be no symptoms.

The discharge coats the walls of the vagina, and is usually without significant irritation, pain, or erythema (redness), although mild itching can sometimes occur. By contrast, the normal vaginal discharge will vary in consistency and amount throughout the menstrual cycle and is at its clearest at ovulation—about two weeks before the period starts. Some practitioners claim that BV can be asymptomatic in almost half of affected women, though others argue that this is often a misdiagnosis.

It may also result from inflammation or congestion of the vaginal mucosa. In cases where it is yellowish or gives off an odor, a doctor should be consulted since it could be a sign of several disease processes, including an organic bacterial infection (aerobic vaginitis) or STD.

After delivery, leukorrhea accompanied by backache and foul-smelling lochia (post-partum vaginal discharge, containing blood, mucus, and placental tissue) may suggest the failure of involution (the uterus returning to pre-pregnancy size) due to infection. A number of investigation such as wet smear, Gram stain, culture, pap smear and biopsy are suggested to diagnose the condition.

The symptoms of a cystocele may include:

- a vaginal bulge

- the feeling that something is falling out of the vagina

- the sensation of pelvic heaviness or fullness

- difficulty starting a urine stream

- a feeling of incomplete urination

- frequent or urgent urination

- fecal incontinence

- frequent urinary tract infections

A bladder that has dropped from its normal position and into the vagina can cause some forms of incontinence and incomplete emptying of the bladder.

Affected newborns may present with acute urinary retention. In adolescent females, the most common symptoms of an imperforate hymen are cyclic pelvic pain and amenorrhea; other symptoms associated with hematocolpos include urinary retention, constipation, back pain, nausea, and diarrhea.

Hematometra or hemometra is a medical condition involving collection or retention of blood in the uterus. It is most commonly caused by an imperforate hymen or a transverse vaginal septum.

A woman may have vaginal itching or burning and may notice a discharge.

The discharge may be excessive in amounts or abnormal in color(such as yellow, gray, or green).

The following symptoms may indicate the presence of infection:

- Irritation or itching of the genital area

- inflammation (irritation, redness, and swelling caused by the presence of extra immune cells) of the labia majora, labia minora, or perineal area

- vaginal discharge

- foul vaginal odor

- pain/irritation with sexual intercourse

An individual with this condition is hormonally normal; that is, the person will enter puberty with development of secondary sexual characteristics including thelarche and adrenarche (pubic hair). The person's chromosome constellation will be 46,XX. At least one ovary is intact, if not both, and ovulation usually occurs. Typically, the vagina is shortened and intercourse may, in some cases, be difficult and painful. Medical examination supported by gynecologic ultrasonography demonstrates a complete or partial absence of the cervix, uterus, and vagina.

If there is no uterus, a person with MRKH cannot carry a pregnancy without intervention. It is possible for the person to have genetic offspring by in vitro fertilization (IVF) and surrogacy. Successful uterine transplant has been performed in limited numbers of patients, resulting in several live births, but the technique is not widespread or accessible to many women.

A person with MRKH typically discovers the condition when, during puberty years, the menstrual cycle does not start (primary amenorrhoea). Some find out earlier through surgeries for other conditions, such as a hernia.

A perineal tear is a laceration of the skin and other soft tissue structures which, in women, separate the vagina from the anus. Perineal tears mainly occur in women as a result of vaginal childbirth, which strains the perineum. Tears vary widely in severity. The majority are superficial and require no treatment, but severe tears can cause significant bleeding, long-term pain or dysfunction. A perineal tear is distinct from an episiotomy, in which the perineum is intentionally incised to facilitate delivery.

Complications may include urinary retention, recurring urinary tract infections and incontinence. The anterior vaginal wall may actually protrude though the vaginal introitus (opening). This can interfere with sexual activity. Recurrent urinary tract infections are common for those who have urinary retention. In addition, though cystocele can be treated, some treatments may not alleviate troubling symptoms, and further treatment may need to be performed. Cystocele may effect the quality of life. Women who have cystocele tend to avoid leaving their home and social situations. The resulting incontinence puts women at risk of being placed in a nursing home or long term care facility.
