What is the posterior vaginal fornix?

Many women don’t know much about their bodies, especially some of the more private parts. So when problems occur in these places, we don’t know exactly which part they are in. It refers to the part of the female genitals called the posterior fornix of the vagina. However, many women are not particularly familiar with this area. Let us now understand what the posterior fornix of the vagina is specifically. I hope that through my introduction, everyone can understand it.

What is the posterior vaginal fornix?

The vagina is an elastic, tubular organ located between the bladder, urethra, and rectum. It has multiple physiological functions in the human reproductive process. It is the channel connecting the uterus and the vulva. It is the only way to discharge menstrual blood and deliver the baby. It is also an important sexual organ.

Normally, the front and back walls of the vagina are close to each other, making the cross section of the vagina form an "H" shape. The upper part bends downward and backward, close to the sacral concave, and its lower end bends forward, making the sagittal plane of the vagina "S" shape. The upper end of the vagina is wider and surrounds the cervix. The annular cavity between the cervix and the vaginal wall is called the vaginal vault. According to its location, it is divided into four parts: front, back, left and right. The posterior fornix is ​​a particularly deep and wide reservoir for semen. In the cesarean position, the posterior fornix is ​​the lowest point in the vagina. This anatomical relationship is conducive to the flow of sperm from the vagina to the cervix, because the external os of the cervix in a normal position is facing the posterior fornix. The posterior fornix is ​​the most expandable part of the vagina, providing the necessary space for the erect penis while preventing excessive displacement of the cervix and possible dyspareunia.

The upper end of the vagina is wider than the lower end. The back wall is about 10 to 12 cm long, and the front wall is about 7 to 9 cm long. The average size of the vagina from the opening to the cervix is ​​about 7.5 cm.

The upper end of the vagina is wider and surrounds the cervix. The annular space between the cervix and the vaginal wall is called the vaginal vault. When harmful bacteria ascend and infect the vaginal vault and cervix, it can cause vaginitis. At this time, the self-cleaning function of the vagina cannot solve the problem. You need to use a wash solution, and it is best if it can penetrate deep into the vaginal vault and cervix. The length of the catheter is determined according to the physiological characteristics of the woman. This can significantly improve the inflammation in the vault area. For example, the patented eight-hole nozzle used for vaginal cleansing liquid can reach deep into the vaginal vault and cervix.

The above content is about the specific part of the posterior fornix of the female vagina. I believe that many women will have a deeper understanding of their bodies after understanding it, so that if problems arise in the future life, we will know how to solve them. No more being embarrassed about not knowing which parts of your body you have.
