For the clam genus Glans, see the article on its family, Carditidae.

The glans (/ɡlænz/,^[1]^[2] plural "glandes" /ˈɡlændˌiːz/; from the Latin word for "acorn")^[3] is a vascular structure located at the tip of the penis in male mammals or a homologous genital structure of the clitoris in female mammals.^[3]

Structure

The exterior structure of the glans consists of mucous membrane, which is usually covered by foreskin or clitoral hood in naturally developed genitalia. This covering, called the prepuce, is normally retractable in adulthood.

The glans naturally joins with the inner labia, and the frenulum of the penis or clitoris. In non-technical or sexual discussions, often the word "clitoris" refers to the external glans alone, excluding the clitoral hood, frenulum, and internal body of the clitoris.^{[citation needed]}

Gender differences in humans

In males, the glans is known as the glans penis, while in females the glans is known as the clitoral glans.

In females, the clitoris is above the urethra. The glans of the clitoris is the most highly innervated part of the external female genitalia.^{[citation needed]}

In other mammals

The pseudo-penis of a female spotted hyena can be distinguished from the male spotted hyena's penis by its greater thickness and more rounded glans.^[4]^[5]^[6]^[7] In both male and female spotted hyenas, the base of the glans is covered with penile spines.^[8]^[9]^[10]

Development

In the development of the urinary and reproductive organs, the glans is derived from the genital tubercle.

Understanding the electrochemical mechanism of K-αMnO2 for magnesium battery cathodes.

ACS applied materials & interfaces.ACS Appl Mater Interfaces.2014 May 7. [Epub ahead of print]
Batteries based on magnesium are an interesting alternative to current state-of-the-art lithium-ion systems; however, high-energy density cathodes are needed for further development. Here we utilize TEM, EDS and EELS in addition to soft-XAS to determine electrochemical magnesiation mechanism of a hi

Balanitis of Zoon (BZ) characterized by an important plasma cell infiltration occurs exclusively in uncircumcised men aged between 40-80 years. We report here a case of BZ in an HIV infected patient who was circumcised since birth. A 43-year old man consulted in 2009 for itchy and not painful glans

The diagnosis of premature ejaculation (PE) was based on a score > 8 at the PEDT five-item questionnaire. Local anaesthetic treatment (LAT) was the first-line therapy. Subjects who obtained a normalisation of EPDT score (≤8) were considered responders to LAT and even affected by lifelong PE d
