|Latin||systema genitale femininum|
The female reproductive system (or female genital system) contains two main parts: the vulva, which includes the labia, clitoris and urinary meatus. The vagina is attached to the uterus through the cervix, while the uterus is attached to the ovaries via the Fallopian tubes. At certain intervals, the ovaries release an ovum, which passes through the Fallopian tube into the uterus. If, in this transit, it meets with sperm, a single sperm can enter and merge with the egg, fertilizing it. Corresponding equivalent among males is the male reproductive system.
During the reproductive process, the egg is not a passive recipient but rather an active participant in the fertilization process. It releases certain molecules that are essential to guiding the sperm which allow the surface of the egg to attach to the sperm's surface. The egg can then absorb the sperm and fertilization begins. The fertilization usually occurs in the oviducts, but can happen in the uterus itself. A zygote will then divide over enough generations of cells to form a blastocyst, which implants itself in the wall of the uterus, where it begins the processes of embryogenesis and morphogenesis. When developed enough to survive outside the womb, the cervix dilates and contractions of the uterus propel the fetus through the birth canal, which is the vagina.
The ova are larger than sperm and have formed by the time a female is born. Approximately every month, a process of oogenesis matures one ovum to be sent down the Fallopian tube attached to its ovary in anticipation of fertilization. If not fertilized, this egg is flushed out of the system through menstruation.

The female internal reproductive organs are the vagina, uterus, uterine tubes (Fallopian tubes, oviducts) and ovaries.
The vagina is a fibro-muscular tubular tract leading from the uterus to the exterior of the body in female mammals, or to the cloaca in female birds and some reptiles. Female insects and other invertebrates also have a vagina, which is the terminal part of the oviduct. The vagina is the place where semen from the male penis is deposited into the female's body at the climax of sexual intercourse, a phenomenon commonly known as ejaculation. The vagina is a canal that joins the cervix (the lower part of uterus) to the outside of the body. It also is known as the birth canal.
The cervix is the lower, narrow portion of the uterus where it joins with the top end of the vagina. It is cylindrical or conical in shape and protrudes through the upper anterior vaginal wall. Approximately half its length is visible to the naked eye, the remainder lies above the vagina beyond view. The vagina has a thick layer outside and it is the opening where the fetus emerges during delivery. The cervix is also named the neck of the uterus.
The organ of humans. The uterus provides mechanical protection, nutritional support, and waste removal for the developing embryo (weeks 1 to 8) and fetus (from week 9 until the delivery). In addition, contractions in the muscular wall of the uterus are important in pushing out the fetus at the time of birth.
The uterus contains three suspensory ligaments that help stabilize the position of the uterus and limits its range of movement. The uterosacral ligaments keep the body from moving inferiorly and anteriorly. The round ligaments restrict posterior movement of the uterus. The cardinal ligaments also prevent the inferior movement of the uterus.
The uterus is a pear-shaped endometrium, and derives nourishment from blood vessels which develop exclusively for this purpose. The fertilized ovum becomes an embryo, develops into a fetus and gestates until childbirth. If the egg does not embed in the wall of the uterus, a female begins menstruation.
The Fallopian tubes or oviducts are two tubes leading from the ovaries of female mammals into the uterus. On maturity of an ovum, the follicle and the ovary's wall rupture, allowing the ovum to escape and enter the Fallopian tube. There it travels toward the uterus, pushed along by movements of cilia on the inner lining of the tubes. This trip takes hours or days. If the ovum is fertilized while in the Fallopian tube, then it normally implants in the endometrium when it reaches the uterus, which signals the beginning of pregnancy.
The ovaries are small, paired organs that are located near the lateral walls of the pelvic cavity. These organs are responsible for the production of the ova and the secretion of hormones. Ovaries are the place inside the female body where ova or eggs are produced. The process by which the ovum is released is called ovulation. The speed of ovulation is periodic and impacts directly to the length of a menstrual cycle.
After ovulation, the ovum is captured by the oviduct, after traveling down the oviduct to the uterus, occasionally being fertilized on its way by an incoming sperm, leading to pregnancy and the eventual birth of a new human being.
The Fallopian tubes are often called the oviducts and they have small hairs (cilia) to help the egg cell travel.

Yeast infection is a common cause of vaginal irritation and according to the Centers for Disease Control and Prevention (CDC) at least 75% of adult women have experienced one at least once in their lifetime. Yeast infections are caused by an overgrowth of fungus in the vagina known as Candida. Yeast infections are usually caused by an imbalance of the pH in the vagina, which is usually acidic. Other factors such as pregnancy, diabetes, weakened immune systems, tight fitting clothing, or douching can also be a cause. Symptoms of yeast infections include itching, burning, irritation, and a white cottage-cheese-like discharge from the vagina. Women have also reported that they experience painful intercourse and urination as well. Taking a sample of the vaginal secretions and placing them under a microscope for evidence of yeast can diagnose a yeast infection. Treatment varies from creams that can be applied in or around the vaginal area to oral tablets that stop the growth of fungus. 
bacteria. The diagnosis for bacterial vaginosis is made if three of the following four criteria are present: (1) Homogenous, thin discharge, (2) a pH of 4.5 in the vagina, (3) epithelial cells in the vagina with bacteria attached to them, or (4) a fishy odor. Bacterial vaginosis is treated with acetic acid, estrogen, or fermented milk. It has been associated with an increased risk of other genital tract infections such as endometritis. 
Diseases of the vagina
Type 1 (circumcision) and Type 2 (clitoridectomy) are the most common forms of FGM making up about 80% of cases and Type 3 is the most extreme form and makes up about 15%. Type 3 is commonly a practice of choice in several African countries. The risks of FGM include physical, sexual, psychological, and pregnancy consequences. The procedure is done in a secluded area in the home and the child may be blindfolded or allowed to see where it will take place. Once they arrive the girl is often immobilized on her back with her legs spread apart so that the procedure may be performed. After the procedure is finished the girl’s legs are bounded together and left in a secluded area to recover for 40 days. The people who perform the “surgical” procedure are usually untrained midwives or elderly women and they more than often use unsterilized razor blades, scissors, knives, broken glass, sharp rocks, or even their teeth. This and the binding of their legs cause infection in the uterus, fallopian tubes, and ovaries. Research has shown that circumcised women have significantly lower levels of self-esteem as opposed to uncircumcised women.

Type 3, also known as vulva, which are the smaller inner folds of the labia minora, is the excision of the clitoris with partial or total removal of the clitoridectomy.

Clitoral hood removal, also known as hoodectomy, is a cosmetic surgery intended to enhance a female's sexual experience. This surgery involves the trimming back of the clitoral hood or a complete clitoris hood removal. Removal of the protective hood allows for more clitoral exposure which increases sensitivity in the clitoris. This procedure, sometimes called female circumcision, is different from a clitoral excision and is not intended to prevent a woman from experiencing sexual pleasure. Clitoral reduction is indicated to reduce the size of the clitoris which may be enlarged due to hormonal abnormalities, ingestion of steroids, or birth. Surgery can reduce the glans or shaft of the clitoris through an outpatient procedure.
There are surgical procedures which change the appearance of external female genitalia. Clitoral hood reduction, also known as clitoridotomy, is a procedure intended to reposition the protruding clitoris and reduce the length and projection of the clitoral hood. The procedure is indicated in women with mild clitoral enlargement who are unwilling to undergo a formal clitoris reduction.
Female genital modification
In the absence of fertilization, the ovum will eventually traverse the entire reproductive tract from the fallopian tube until exiting the vagina through menstruation.
The reproductive tract (or genital tract) is the lumen that starts as a single pathway through the vagina, splitting up into two lumens in the uterus, both of which continue through the Fallopian tubes, and ending at the distal ostia that open into the abdominal cavity.
