The ovarian fossa is the region that is bounded by the external iliac artery and in front of the ureter and the internal iliac artery. This area is about 4 cm x 3 cm x 2 cm in size. [3] [4] The ovaries are surrounded by a capsule, and have an outer cortex and an inner medulla. [4]
Lawrence, citing Masters and Johnson's Human Sexual Response (1966), states that pages 73 and 74 of that book show that typical vaginal depth in Masters and Johnson's participants ranged from 7–8 cm (2.8–3.1 in) in an unstimulated state, to 11–12 cm (4.3–4.7 in) during sexual arousal with a speculum in place.

Each tube is a muscular hollow organ [3] that is on average between 10 and 14 cm (3.9 and 5.5 in) in length, with an external diameter of 1 cm (0.39 in). [4] It has four described parts: the intramural part, isthmus, ampulla, and infundibulum with associated fimbriae.
Human ova grow from primitive germ cells that are embedded in the substance of the ovaries. [10] The ovum is one of the largest cells in the human body, typically visible to the naked eye without the aid of a microscope or other magnification device. [11] The human ovum measures approximately 120 μm (0.0047 in) in diameter. [12]
The human female reproductive system is made up of the internal and external sex organs that function in the reproduction of new offspring. The reproductive system is immature at birth and develops at puberty to be able to release matured ova from the ovaries , facilitate their fertilization , and create a protective environment for the ...
On average, the ectocervix is 3 cm (1.2 in) long and 2.5 cm (1 in) wide. [3] Blood is supplied to the cervix by the descending branch of the uterine artery [9] and drains into the uterine vein. [10] The pelvic splanchnic nerves, emerging as S2–S3, transmit the sensation of pain from the cervix to the brain. [5]
Because of the presence of the cervix in the front wall of the vagina, there is a difference in length between the front wall, approximately 7.5 cm (2.5 to 3 in) long, and the back wall, approximately 9 cm (3.5 in) long. [10] [24] During sexual arousal, the vagina expands both in length and width. If a woman stands upright, the vaginal canal ...
