The female internal reproductive organs include

The female reproductive organ consists of two parts: the internal reproductive organ and the reproductive organ. The genitals refer to the exposed part of the male reproductive organs, also known as the private parts, including the labia majora, labia minora, clitoris, vestibule of the vagina, Bartholin's glands and the hymen. The internal reproductive organs refer to the internal organs of the male reproductive organs, which are located in the pelvis and include the vagina, uterus, bilateral fallopian tubes and uterus and ovaries.

(1) Mons pubis: The mons pubis is an inverted triangle-shaped protrusion of skin in front of the ischial tuberosity just below the center of the abdomen. The inner edge is divided by the metatarsal groove and the abdomen, which is rich in sebaceous glands and sebaceous glands. The fat is very rich, soft and plump. Male pubic hair grows after puberty, and its distribution is also in an inverted triangle, with the upper edge basically in a straight line and extending directly below to the labia majora. Male pubic hair is soft, fine and curly, but its number, density and distribution vary greatly. A small number of adult women have sparse pubic hair, which is also a normal physiological phenomenon. During sexual intercourse, the mons pubis acts as a hydraulic buffer to avoid direct harm to the male reproductive organs and body.

(2) Labia majora: The labia majora are a pair of vertical raised skin folds located just below the mons pubis and on both sides of the vagina. They contain a lot of fat and are quite elastic. The crack between the two labia is called the labia majora. The vulva fissure of adult Virgo is closed, which prevents the exposure of the labia, clitoris, vulva and urethra, and has a significant protective effect. The front ends of the upper and lower labia majora are connected to the mons pubis, which is called the anterior labial connection. The rear end development stops at the perineum, which is called the postlabial synergy. The outer side is brown-black due to pigmentation, has many sebaceous glands and skin glands, and is also covered with male pubic hair. The inner edge is light rose in color, like mucous membrane, thin and smooth, with no pubic hair. During sexual arousal, non-pregnant women's vagina stretches significantly to both sides, while primipara's vagina expands 2 to 3 times due to blood vessel congestion and swelling. The close-fitting labia majora can protect the vagina from cleanliness and prevent the sensitive clitoris from being easily stimulated.

(3) Labia: The labia are a pair of skin folds on the inner side of the labia majora. It contains little fat, has a smooth surface, no pubic hair, and is quite elastic. The front end of the labia develops under the clitoris, converges up and down to form the frenulum clitoridis, and is continuous with the foreskin surrounding the clitoris. The posterior end of the labia majora is connected with the posterior end of the labia majora. During sexual intercourse, the labia plays the role of correctly guiding the penis into the vagina. During sexual arousal, the labia minora become engorged and dilated, which can increase the effective length of the vagina by at least 1 cm and increase sensitivity.

(4) Clitoris: The clitoris is equivalent to the penis of men. It is the female's sexual organ and sensor. It is located at the anterior junction of the labia majora and has rich sensory nerve endings. The clitoris is composed of two hardened corpora cavernosa, covered with a fibrous membrane, about 4 cm long, cylindrical, and divided into two parts: the vagina and the head. The clitoris has rich sensory nerve endings, so it is very sensitive to touch. During sexual intercourse, the muscles of the vulva contract, making the clitoris timid and isolated from the vagina. The male genitals do not directly contact the clitoris, but only keep the foreskin of the penis close to the labia. When the male genitals twitch in the female vagina, they stimulate the clitoris by touching the labia.
