Urethral gland .
In femalehuman anatomy ,Skene's glands or theSkene glands (/s k iː n / SKEEN , also known as thelesser vestibular glands orparaurethral glands [ 1] ) are twoglands located towards the lower end of theurethra . The glands are surrounded by tissue that swells withblood duringsexual arousal , and secrete a fluid, carried by theSkene's ducts to openings near theurethral meatus , particularly duringorgasm .
Structure and function [ edit ] The Skene's glands' openings are located in thevestibule of thevulva , around the lower end of theurethra .[ 2] The two Skene's ducts lead from the Skene's glands to the vulvar vestibule, to the left and right of theurethral opening , from which they are structurally capable of secreting fluid.[ 2] [ 3] Although there remains debate about the function of the Skene's glands, one purpose is to secrete a fluid that helps lubricate the urethral opening.[ 2] [ 3]
Skene's glands produce a milk-likeultrafiltrate ofblood plasma . The glands may be the source offemale ejaculation ,[ 3] [ 4] [ 5] but this has not been proven.[ 4] Because they and the maleprostate act similarly by secretingprostate-specific antigen (PSA), which is anejaculate protein produced in males, andprostatic acid phosphatase , some authors refer to the Skene's glands as the "female prostate".[ 3] [ 5] [ 6] They arehomologous to the male prostate (developed from the sameembryological tissues),[ 7] but the homology is still a matter of research.[ 8] Female ejaculate may result fromsexual activity for some women, especially duringorgasm .[ 3] [ 4] In addition to PSA and acid phosphatase, Skene's gland fluid contains high concentrations ofglucose andfructose .[ 3]
In an amount of a fewmilliliters , fluid is secreted from these glands when stimulated from inside thevagina .[ 9] [ 10] Female ejaculation and squirting (secretion of large amounts of fluid) are believed by researchers to be two different processes. They may occur in combination during orgasm. Squirting alone is a sudden expulsion of liquid that at least partly comes from the bladder and contains urine, whereas ejaculation fluid includes a whitish transparent ejaculate that appears to come from the Skene's gland.[ 3] [ 11]

While the glands were first described in 1672 byRegnier de Graaf and by the Frenchsurgeon Alphonse Guérin (1816–1895),[ 15] they were named after the Scottishgynaecologist Alexander Skene , who wrote about it inWestern medical literature in 1880.[ 16] [ 17] [ 18] In 2002,[ 19] the termfemale prostate as a second term afterparaurethral gland was added inTerminologia Histologica by theFederative International Committee on Anatomical Terminology . The 2008 edition notes that the term was introduced "because of the morphological and immunological significance of the structure".[ 20]
Horses ,dogs ,sheep , andpigs are examples of othermammals that have these glands (minor vestibular glands).[ 21]
