How is the formation of paired genitalia?
Under the influence of teratogenic factors there is a violation of the process of laying the genital organs at the stage of embryogenesis. So, for example, 2 vaginas are formed due to incomplete fusion of such formations as paired Muller channels.
As a rule, doctors find it difficult to give an unambiguous answer to the question of the reasons for such a violation. However, with almost 100% certainty, it can be said that the development of this kind of anomaly is facilitated by:
- influence on the future baby of harmful environmental factors;
- viral infections (rubella, influenza, toxoplasmosis during pregnancy);
- toxic drugs at early gestation (8-16 weeks).
What kinds of forms of doubling the vagina exist?
So, most often among similar anomalies in gynecology is recorded a complete doubling of the uterus and vagina (two uterus and two vaginas). In such cases, when the patient is examined, the doctor discovers 2 completely isolated uterus, each of which has 1 fallopian tube and 1 ovary. In this case, the presence of two uterine necks and 2 vaginas are recorded. In some cases, both the uterus and both vaginas can be separated by the bladder or rectum, and sometimes closely adjoin each other. In most cases, both halves of the vagina are unequally functional and anatomically complete, often one of them is somewhat better developed.
The second form of this disorder is the doubling of the uterus, with only one vagina (bicorne, saddle-shaped uterus, intrauterine septum).
As a rule, doubling of the uterus and vagina are combined with other malformations of the genitourinary system. So, for example, when doubling the uterus with partial aplasia of one of the vaginas, almost always aplasia of the kidney is observed. Also quite often in patients with a double vagina there is atresia of the hymen.
How is the diagnosis of this violation?
The presence of 2 separate vaginas in a girl can not cause any clinical manifestations. Therefore, quite often such patients about the peculiarities of the structure of their reproductive organs, find out when they visit a gynecologist.
However, with a full doubling of the uterus and vagina, which is combined with atresia of one of the vaginal cavities, symptomatology may appear 3-6 months after menarche (the first menstruation). At the same time, a young girl complains of strong, flaring pains in the lower abdomen, which, after taking antispasmodic drugs, do not disappear.
In those cases when there is a fistulous passage in the intervaginal septum, there may be an outflow of menstrual blood through the vagina. In this case, the girl often notes the appearance of bloody discharge, not associated with menstruation, which acquire a purulent character.
How often do two vaginas occur?
It is worth noting that this type of violation is rarely recorded. That is why many women do not believe such a statement, and they often ask doctors if two women have vaginas.
Such a violation does take place. So, for example, Hazel Jones found her two vaginas only at 18 years old. Before she turned to the doctor, she did not even suspect it. In this case, the first feature of this was noticed by the girl's girlfriend, who told her that she had "something wrong", as it should be.
