Is the hymen easy to break?

Before puberty, because the uterus and ovaries secrete very little estrogen, the vaginal mucosa is thin, the walls are less wrinkled, and the acidity is low, so the resistance is poor. The rupture of the hymen has a protective effect to prevent bacteria from invading the vagina. After puberty, with the growth and development of the uterus and ovaries, the increase of estrogen in the body, the resistance of the vagina is improved to a certain extent, and the rupture of the hymen will gradually lose its function. The hymen hole is a physiological necessity.

The broken hymen covers the inner and outer exit of the vagina, which is about 1 to 2 mm thick. There is a small round hole in the middle, called the "hymen hole", with a diameter of 1 cm. It is generally circular, oval or serrated; some are crescent-shaped, with the hole biased towards one side; some are septum-shaped holes, with two small round holes arranged left and right or up and down; some have many scattered small round holes, like dice.

During menstruation, menstruation is discharged from the body through this small round hole. If there is no small round hole on the membrane, the menstruation will be blocked every month, accumulate in the vagina, and expand upward to the uterus and bilateral fallopian tubes, and even flow into the abdomen, causing bilateral fallopian tube damage, intestinal adhesions, and abdominal infection. This is medically called "hymen occlusion" and gynecological minimally invasive surgery is necessary.

During female puberty, because the uterus and ovaries metabolize less estrogen, the vaginal mucosa is thin, the walls are less wrinkled, the acidity is low, and the resistance is weak, the rupture of the hymen has the function of preventing bacteria from invading the vagina. After puberty, with the growth and development of the uterus and ovaries, the body's estrogen increases, the resistance of the vagina increases, and the hymen breaks and loses its function.

During the first sexual intercourse, the hymen is broken and torn, causing bleeding. Because the hymen can be broken in various ways, the degree of the tearing will vary greatly, and the degree of pain will also be different. The septate hymen will bleed more, accompanied by more intense pain. When the mouth-shaped hymen is broken, there will be very little bleeding and basically no pain. The thick and very stretchy umbrella-shaped hymen may not break at all after it breaks!
