Ovarian follicle
An ovarian follicle (also known as a Graafian follicle in its mature state) is the basic unit of female reproductive biology and is composed of roughly spherical aggregations of cells and contains a single oocyte.
Gross anatomy
An ovarian follicle can be initiated to grow and develop, culminat...

Round ligament of the uterus
The round ligament is one of the supporting structures of the uterus. It has a function in uterine anteflexion.
Embryology
Together with the ligament of the ovary, it is one of the remnants of the gubernaculum in females.
Gross anatomy
The round ligament is a rope-like fibromuscular band tha...

Uterus
The uterus is an extraperitoneal hollow, thick-walled, muscular organ of the female reproductive tract that lies in the lesser pelvis.
Gross anatomy
The uterus has an inverted pear shape. It measures about 7.5 cm in length, 5 cm wide at its upper part, and nearly 2.5 cm in thickness in adults....
Article
Junctional zone (uterus)
Junctional zone is a region representing the inner myometrium of the uterus and is a very important imaging feature in pelvic MR imaging for the interpretation of various pathologies. In its intact state, it is usually visible on MRI as a low T2 signal layer beneath the endometrium. At times, it...
Article
Müllerian duct
The Müllerian ducts (or paramesonephric ducts) are paired ducts of mesodermal origin in the embryo. They run laterally down the side of the urogenital ridge and terminate at the Müllerian eminence in the primitive urogenital sinus.
In the female, they will develop to form the uterine tubes, ute...
Article
Ovary
The ovaries (TA: ovarium 9) are paired female gonads of the reproductive and endocrine systems. They lie within the ovarian fossa on the posterior wall of the true pelvis and form part of the adnexa.
Gross anatomy
The ovaries are firm and ovoid in shape and measure approximately 1.5-3.0 cm × ...
Article
Fallopian tube
The fallopian tube (TA: tuba uterina 8), also known as the uterine tube or, less commonly, the oviduct, is a paired hollow tube that bridges the ovary and uterus and functions to convey the mature ovum from the former to the latter. If conception occurs, it usually does so within the tube, which...

Bicornuate uterus
A bicornuate uterus is a type of uterine duplication anomaly. It can be classified as a class IV Mullerian duct anomaly.
Epidemiology
Overall, congenital uterine anomalies occur in ~1.5% of females (range 0.1-3%). Bicornuate uteri are thought to represent ~25% (range 10-39%) of Mullerian duct ...
Article
Vagina
The vagina is a midline fibromuscular tubular organ positioned in the female perineum extending superiorly from the vulva, to the cervix and uterus in the pelvis.
Gross anatomy
The vagina is 6-8 cm in length, extending posterosuperior from the vestibule through the urogenital diaphragm to the...
Article
Cervix
The cervix or uterine cervix is the lower constricted segment of the uterus providing the passage between the uterus proper and the vagina.
Gross anatomy
The cervix is somewhat conical in shape, with its truncated apex directed posteriorly and inferiorly. The inferior aspect of the cervix pro...
Article
Retroverted uterus
A retroverted uterus is a normal variation of female pelvic anatomy in which the body of the uterus is tilted backwards (usually leans forward, i.e. anteverted) on itself to match the isthmus of the neck and lower uterine segment. There are variable grades of uterine retroversion.
Epidemiology

Article
Unicornuate uterus
A unicornuate uterus or unicornis unicollis is a type of Müllerian duct anomaly (class II). It is also known as a banana-shaped uterus6,7, because of the shape the single horn assumes, and it usually drains into a single fallopian tube.
Epidemiology
This type can account for ~10% (range 6-13%)...
Article
Clitoris
The clitoris (plural: clitorides), the female homologue of the penis, and part of the female reproductive system, is situated at the anterior aspect of the labia minora. The clitoris, like the penis, is formed of a body and glans, formed respectively from the crura of the clitoris and the bulbs ...

Pubococcygeal line
The pubococcygeal line (PCL) is a reference line for the pelvic floor on imaging studies and helps detect and grade pelvic floor prolapse in defecography studies. It is defined as a line that connects the inferior border of the symphysis pubis (anterior margin) to the final coccygeal joint (post...
Article
H and M lines (pelvic floor)
The H and M lines are reference lines for the pelvic floor on imaging studies and help detect and grade pelvic floor prolapse on defecography studies.
The H line is drawn from the inferior margin of the pubic symphysis to the posterior aspect of the anorectal junction, and represents the diamet...
