Diagram of complete clitoris

Stimulation of the clitoris may assist in the process of physical arousal due to the fact that these nerves also supply the structures of the vagina. Usually the ovum is then swept into the uterine tubes. When the contractions of labor begin, the walls of the uterus contract as they are stimulated by the pituitary hormone oxytocin ahk-see-TOE-sin. In all placental mammals, including humans, the endometrium builds a lining periodically which is shed or reabsorbed if no pregnancy occurs. The clitoris - or clit - is, without a doubt, incredible. You may have seen this number thrown around a lot, but that's because it's so impressive: The clitoris has 8, nerve endings in its tiny surface area, while the penis has around 4, on the whole thing including head and shaft. The male gonads make male gametes sperm.

Genital tubercle. It partially contributes to erection, which are primarily caused by the two corpora cavernosa that comprise the bulk of the shaft; like the female cavernosa, the male cavernosa soak up blood and become erect when sexually excited. Besides enlargement, congenital abnormalities of the clitoris may also include agenesis or hypoplasia. While female spotted hyenas are sometimes referred to as hermaphrodites or as intersex , [] and scientists of ancient and later historical times believed that they were hermaphrodites, [] [] [] modern scientists do not refer to them as such. Clinical anatomy applied anatomy for students and junior doctors 13th ed. Female spotted hyenas have a clitoris 90 percent as long and the same diameter as a male penis millimeters long and 22 millimeters in diameter , [] and this pseudo-penis 's formation seems largely androgen -independent because it appears in the female fetus before differentiation of the fetal ovary and adrenal gland. Biology of Women.

Upon anatomical study, the penis can be described as a clitoris that has been mostly pulled out of the body and grafted on top of a significantly smaller piece of spongiosum containing the urethra. In Bruce Bagemihl 's survey of The Zoological Record — — which contains over a million documents from over 6, scientific journals — articles focusing on the penis were found, while 7 were found focusing on the clitoris. Believing that vaginal orgasms are "a physiological impossibility" because the vagina has insufficient nerve endings for sexual pleasure or climax, he "concluded that satisfaction from penile penetration [is] mainly psychological or perhaps the result of referred sensation".

In humans, the female reproductive system is immature at birth and develops to maturity at puberty to be able to produce gametes , and to carry a foetus to full term.
