8 common shapes of female vulva? Understand your body scientifically

　　This article will analyze the common morphological classification of the vulva from a medical perspective, combining anatomical structure and healthy Self-test method, help female Correctly understand one's own characteristics, dispel misunderstandings, and provide scientific nursing advice to avoid anxiety or excessive intervention caused by cognitive biases.

　　1. 8 common forms of female vulva: diversity of individual differences

　　The classification of vulva morphology is not a standard medical terminology, but common types summarized by folk can assist in understanding individual differences. The following morphological characteristics are affected by genetics, hormones and development. If there are no abnormal symptoms such as pain, itching, etc., they are within the normal range:

　　Steamed bun type : The perineum is round and plump, with only a thin slit visible when the legs are brought together, and less wrinkles. It is more common in women who have not given birth or who are thin.

　　butterfly type : The labia majora are relatively plump, with obvious folds, and naturally spread out on both sides, resembling butterfly wings, which is one of the more common shapes.

　　water drop type : The labia majora bulges in the middle, becomes narrower on both sides, and is generally drop-shaped with fewer wrinkles. skin smooth.

　　anemone type : There are rich folds around the vaginal opening and the labia are of moderate size. They may have unique reactions due to muscle contraction during sexual stimulation.

　　willow leaf type : The labia minora are as slender as a willow leaf, with a tapered front end and a wide rear end, which may slightly protrude outside the labia majora.

　　petal type : The labia minora are thick and have wavy edges, shaped like petals, and may be darker in color. This is mostly related to genetics or hormone levels.

　　closed type : The labia majora naturally closes tightly, almost completely covering the vaginal opening and urethral opening, and has a strong protective effect on sensitive parts.

　　white tiger type : There is no distribution of pubic hair in the perineal area, but the shape of the labia may show any of the above types, which is related to hormone levels or genetic factors.

　　Key reminder : Most descriptions of vulva morphology are visual summaries. Actual individual differences may have mixed characteristics (such as the "water drop + petal" composite type), so there is no need to force a conclusion.

　　2. Causes of differences in vulva morphology: the combined effects of genetics, hormones and development

　　genetic factors

　　Genes determine the basic framework of anatomy, such as the symmetry of the labia majora and the length of the clitoral hood. For example, if one parent has a thicker labia minora, their children may inherit similar characteristics. This difference is present from birth and will last throughout their lives.

　　Fluctuations in hormone levels

　　puberty : The increase in estrogen secretion promotes thickening and pigmentation of the labia, and the shape gradually develops from childish to mature.

　　Pregnancy : Hormone changes may aggravate pigmentation, during childbirth fetus Passing through the birth canal may stretch the perineal tissue and change its original shape.

　　surround menopause Expect : Decreased estrogen causes the labia to shrink, lose elasticity, make the skin thinner and reduce wrinkles.

　　lifestyle and environment

　　friction irritation : Cycling or wearing tight pants for a long time may cause the labia majora fat pad to proliferate, or cause local pigmentation due to repeated friction.

　　cleaning habits : Excessive use of alkaline lotions may damage the skin barrier and cause thickening of keratinization.； Proper cleaning and keeping dry will help maintain normal shape.

　　3. Vulva health self-examination and care: focus on function rather than appearance

　　Self-examination points

　　Observe symmetry : When standing or lying down, check whether the labia majora on both sides are symmetrical and whether there is swelling or falling sensation on one side.

　　touch skin status : The skin should be soft and free of induration to avoid cauliflower-like growths, white spots or ulcers (which may indicate genital warts, Leukoplakia on vulva or tumors).

　　Check for secretions : Normal secretion is white or transparent and has no peculiar smell.； If there is tofu-like, yellow-green or fishy-smelling discharge, it needs to be investigated Vaginitis。

　　Scientific nursing advice

　　Cleaning method : Wash your vulva with warm water every day and avoid using irritating products； Change sanitary napkins every 2-3 hours during menstruation to prevent bacterial growth.

　　Clothing choices : Give priority to cotton breathable underwear and avoid chemical fiber materials.； Wear sweat-absorbent fabrics when exercising to reduce friction and damage.

　　behavioral habits : Avoid sitting for long periods of time which may cause pressure on the perineum, and pay attention to cleanliness before and after sexual intercourse.； Kegel exercises can be performed during pregnancy to strengthen the support of the pelvic floor muscles.

　　Exception handling

　　sudden change in form : If unilateral labia are swollen and the vaginal opening is incompletely closed, it may indicate a Bartholin's gland cyst or anterior vaginal wall bulge, which requires medical evaluation.

　　accompanying symptoms : If you have persistent itching, pain or difficulty urinating, it may be related to vulvitis , vaginitis or urethritis, the cause needs to be determined through secretion testing.
