The prognosis is determined primarily by the cancer stage. Most tumours are discovered at an early stage and have a good prognosis, especially when compared to uterine carcinosarcoma. Five year survival for stage I and stage III tumours is approximately 80% and 50% respectively.

Uterine adenosarcomas are typically treated with a total abdominal hysterectomy and bilateral salpingoophorectomy (TAH-BSO). Ovary sparing surgery may be done in women wishing to preserve fertility.

Endometrial polyps usually occur in women in their 40s and 50s. Endometrial polyps occur in up to 10% of women. It is estimated that they are present in 25% of women with abnormal vaginal bleeding.

Endometrial polyps are usually benign although some may be precancerous or cancerous. About 0.5% of endometrial polyps contain adenocarcinoma cells. Polyps can increase the risk of miscarriage in women undergoing IVF treatment. If they develop near the fallopian tubes, they may lead to difficulty in becoming pregnant. Although treatments such as hysteroscopy usually cure the polyp concerned, recurrence of endometrial polyps is frequent. Untreated, small polyps may regress on their own.

In the United States, uterus didelphys is reported to occur in 0.1–0.5% of women. It is difficult to know the exact occurrence of this anomaly, as it may go undetected in the absence of medical and reproductive complications.

Over one million cases of acute salpingitis are reported every year in the US, but the number of incidents is probably larger, due to incomplete and untimely reporting methods and that many cases are reported first when the illness has gone so far that it has developed chronic complications. For women age 16–25, salpingitis is the most common serious infection. It affects approximately 11% of females of reproductive age.

Salpingitis has a higher incidence among members of lower socioeconomic classes. However, this is thought of being an effect of earlier sex debut, multiple partners, and decreased ability to receive proper health care rather than any independent risk factor for salpingitis.

As an effect of an increased risk due to multiple partners, the prevalence of salpingitis is highest for people age 15–24 years. Decreased awareness of symptoms and less will to use contraceptives are also common in this group, raising the occurrence of salpingitis.

Invasive hydatidiform mole, also known as invasive mole and chorioadenoma destruens is a type of neoplasia that grows into the muscular wall of the uterus. It is formed after conception (fertilization of an egg by a sperm). It may spread to other parts of the body, such as the vagina, vulva, and lung.

For the affected, 20% need hospitalization.

Regarding patients age 15–44 years, 0.29 per 100,000 dies from salpingitis.

However, salpingitis can also lead to infertility because the eggs released in ovulation can't get contact with the sperm. Approximately 75,000-225,000 cases of infertility in the US are caused by salpingitis. The more times one has the infection, the greater the risk of infertility. With one episode of salpingitis, the risk of infertility is 8-17%. With 3 episodes of salpingitis, the risk is 40-60%, although the exact risk depends on the severity of each episode.

In addition, damaged oviducts increase the risk of ectopic pregnancy. Thus, if one has had salpingitis, the risk of a pregnancy to become ectopic is 7 to 10-fold as large. Half of ectopic pregnancies are due to a salpingitis infection.

Other complications are:

- Infection of ovaries and uterus

- Infection of sex partners

- An abscess on the ovary

A number of twin gestations have occurred where each uterus carried its pregnancy separately. A recent example occurred on February 26, 2009, when Sarah Reinfelder of Sault Ste. Marie, Michigan delivered two healthy, although seven weeks premature, infants by cesarean section at Marquette General Hospital. It is possible that the deliveries occur at different times, thus the delivery interval could be days or even weeks.

There are two primary types of vaginal cancer: squamous-cell carcinoma and adenocarcinoma.

- Vaginal squamous-cell carcinoma arises from the squamous cells (epithelium) that line the vagina. This is the most common type of vaginal cancer. It is found most often in women aged 60 or older.

- Vaginal adenocarcinoma arises from the glandular (secretory) cells in the lining of the vagina that produce some vaginal fluids. Adenocarcinoma is more likely to spread to the lungs and lymph nodes.

- Clear cell adenocarcinoma occurs in a small percentage of women (termed "DES-Daughters") born between 1938 and 1973 (later outside the United States) that were exposed to the drug diethylstilbestrol (DES) in utero. DES was prescribed to 5 to 10 million mothers period to prevent possible miscarriages and premature births. Typically, women develop DES-related adenocarcinoma before age 30, but increasing evidence suggests possible effects or cancers (including other forms of vaginal glandular tumors) at a later age. DES-exposure in women is also linked to various infertility and pregnancy complications. Daughters exposed to DES in utero may also have an increased risk of moderate/severe cervical squamous cell dysplasia and an increased risk of breast cancer. Approximately one in 1,000 (0.1%) DES Daughters will be diagnosed with clear cell adenocarcinoma. The risk is virtually non-existent among premenopausal women not exposed to DES.

- Vaginal germ cell tumors (primarily teratoma and endodermal sinus tumor) are rare. They are found most often in infants and children.

- Sarcoma botryoides, a rhabdomyosarcoma also is found most often in infants and children.

- Vaginal melanoma, a melanoma that appears in the vagina.

Cervical agenesis is estimated to occur in 1 in 80,000 females. It is often associated with deformity of the vagina; one study found that 48% of patients with cervical agenesis had a normal, functional vagina, while the rest of the cases were accompanied by vaginal hypoplasia.

Women with the condition may be asymptomatic and unaware of having a uniconuate uterus; normal pregnancy may occur. In a review of the literature Reichman et al. analyzed the data on pregnancy outcome of 290 women with a unicornuate uterus. 175 women had conceived for a total of 468 pregnancies. They found that about 50% of patients delivered a live baby. The rates for ectopic pregnancy was 2.7%, for miscarriage 34%, and for preterm delivery 20%, while the intrauterine demise rate was 10%. Thus patients with a unicornuate uterus are at a higher risk for pregnancy loss and obstetrical complications.

The prevalence of uterine malformation is estimated to be 6.7% in the general population, slightly higher (7.3%) in the infertility population, and significantly higher in a population of women with a history of recurrent miscarriages (16%).

Most studies are based on populations of women who have experienced a pregnancy loss and thus do not address the issue of the prevalence in the general population. A screening study by Woelfer et al. of women without a history of reproductive problems found that about 3% of women had a uterine septation; the most common anomaly in their study was an arcuate uterus (5%), while 0.5% were found to have a bicornuate uterus. In contrast, in about 15% of patients with recurrent pregnancy loss anatomical problems are thought to be causative with the septate uterus as the most common finding.

Cancer of the vagina is rare and is only 2% of all gynecological cancers less than 0.5% of all cancers in women Estimated new cases in the United States in 2017 are 4,810. Deaths from vaginal during the same time were 1,240. It is more common in older women.

In the UK, 254 cases of Vaginal cancer were identified in 2014. Deaths from vaginal cancer in this period were 110. Out of those with vaginal cancer, 53% are related to HPV infection.

Sarcoma botryoides normally is found in children under 8 years of age. Onset of symptoms occurs at age 3 years (38.3 months) on average. Cases of older women with this condition have also been reported.

A unicornuate uterus represents a uterine malformation where the uterus is formed from one only of the paired Müllerian ducts while the other Müllerian duct does not develop or only in a rudimentary fashion. The sometimes called "hemi-uterus" has a single horn linked to the ipsilateral fallopian tube that faces its ovary.

Risk factors for developing a cystocele are:

- an occupation involving or history of heavy lifting

- pregnancy and childbirth

- chronic lung disease/smoking

- family history of cystocele

- exercising incorrectly

- ethnicity (risk is greater for Hispanic and whites)

- hypoestrogenism

- pelvic floor trauma

- connective tissue disorders

- spina bifida

- hysterectomy

- cancer treatment of pelvic organs* childbirth; correlates to the number of births

- forceps delivery

- age

- chronically high intra-abdominal pressures

- chronic obstructive pulmonary disease

- constipation

- obesity

Connective tissue disorders predispose women to developing cystocele and other pelvic organ prolapse. The tensile strength of the vaginal wall decreases when the structure of the collagen fibers change and become weaker.

The condition may not be known to the affected individual and not result in any reproductive problems; thus normal pregnancies may occur. However, it is associated with a higher risk for miscarriage, premature birth, and malpresentation. According to the classical study by Buttram there is a 60% risk of a spontaneous abortion, this being more common in the second than in the first trimester. However, there is no agreement on this number and other studies show a lower risk. Woelfer found that the miscarriage risk is more pronounced in the first trimester.

The condition is also associated with abnormalities of the renal system. Further, skeletal abnormalities have been linked to the condition.

The disease used to be uniformly fatal, with a 5-year survival rate between 10 and 35%. As a result, treatment was radical surgery. New multidrug chemotherapy regimens with or without radiation therapy are now used in combination with less radical surgery with good results, although outcome data are not yet available.

If untreated, the accumulation of menstrual fluid in the uterus caused by cervical agenesis can lead to hematocolpos, hematosalpinx, endometriosis, endometrioma and pelvic adhesions.

A cystocele occurs when the muscles, fascia, tendons and connective tissues between a woman’s bladder and vagina weaken, or detach. The type of cystocele that can develop can be due to to three vaginal wall attachment failures. The midline defect, the paravaginal defect, and the transverse defect. The midline defect is a cystocele is caused by the overstretching of the vaginal wall. The paravaginal defect is the separation of the vaginal connective tissue at the arcus tendineus fascia pelvis. The transverse defect is when the pubocervical fascia becomes detached from the top (apex) of the vagina. There is some pelvic prolapse in 40-60% of women who have given birth. Muscle injuries have been identified in women with cystocele. These injuries are more likely to occur in women who have given birth than those who have not. These muscular injuries result in less support to the anterior vaginal wall.

Some women with connective tissue disorders are predisposed to developing anterior vaginal wall collapse. Up to one third of women with Marfan syndrome have a history of vaginal wall collapse. Ehlers-Danlos syndrome in women is associated with a rate of 3 out of 4.

Endometrial atrophy, uterine fibroids, and endometrial cancer are common causes of postmenopausal vaginal bleeding.

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

A uterine malformation is a type of female genital malformation resulting from an abnormal development of the Müllerian duct(s) during embryogenesis. Symptoms range from amenorrhea, infertility, recurrent pregnancy loss, and pain, to normal functioning depending on the nature of the defect.
