Question

What is penis?
Write a deeply note on it? ​

Answer 1

Explanation:

A penis (plural penises or penes) is the primary sexual organ that male animals use to inseminate females (or hermaphrodites) during copulation.Such organs occur in many animals, both vertebrate and invertebrate, but males do not bear a penis in every animal species, and in those species in which the male does bear a so-called penis, the penises in the various species are not necessarily homologous.

The term penis applies to many intromittent organs, but not to all. As an example, the intromittent organ of most cephalopoda is the hectocotylus, a specialized arm, and male spiders use their pedipalps. Even within the Vertebrata there are morphological variants with specific terminology, such as hemipenes.

In most species of animals in which there is an organ that might reasonably be described as a penis, it has no major function other than intromission, or at least conveying the sperm to the female, but in the placental mammals the penis bears the distal part of the urethra, which discharges both urine during urination and semen during copulation.

Answer 2

• Male animals utilise their penises (plural penises or penes) to inseminate females (or hermaphrodites) during copulation.
• Males do not bear a penis in every animal species, and in those species where the male does bear a so-called penis, the penises in the various species are not always comparable.
• Many, but not all, intromittent organs are referred to as the penis.
• Most cephalopods, for example, have an intromittent organ called the hectocotylus, which is a specialised arm, while male spiders have pedipalps.
• There are morphological varieties with particular nomenclature, such as hemipenes, even within the Vertebrata.
