Premature ejaculation (PE) is recognized to be most common male sexual disorder, it provides difficulties for the professionals who treat men with PE because there is neither a universally accepted definition nor a medication approved by the Food and Drug Administration(FDA) with which to treat it.

Some of definition assigned to PE, one of the major guidelines, such as The Diagnostic and statistical Manual of Mental Disorder, Fourth Edition (DSM-IV-TR),The international Consultation on Urological Disease or The American Urological Association Guideline . The DSM –IV- TR has defined PE as “ persistent or recurrent ejaculation with minimal sexual stimulation before on , or shortly after penetration and before the person wishes it ” Similar Definition are given in The Internation Consulation on Urological Disease and The America Urological Association (AUA) Guideline. The latter defines PE as ejaculation That “Occurs Sooner than desired , either before or shortly after penetration , causing distress to either one or both partners”
Sexual Anatomy
Male Reproductive System : Overview
The male external structures are the penis and the scrotum (a pouch which protects the testes ). The penis consist of the glans (the head or the trip), and the shaft (the body). The glans is covered by a fold of skin called the foreskin. The scrotum surround and protects the two testes, the internal structures also referred to as testicles.
The testes are the male gonads (organs that produce male seeds i.e Sperms) and contain hundreds of tiny seminiferous tubules where sperm cells are produced. The epididymis is a small oblong body which rests on the surface of the tests which rests on the surface of the testes where sperm mature and are stored. The epididymis leads into the vas deferens (narrow tubes carry sperm away from the testest)
