Premature Ejaculation Is Very Common, But What's Premature?

Premature ejaculation (PE) is probably men's most common sexual
dysfunction. It's practically the norm for young men to experience it
during their first explorations of sex. But for some, the problem never
goes away, while others find it returning later in life. Doctors are
not quite sure how to explain either phenomenon.
urinating or lacking bowel control when we are babies, I think
ejaculation is a behavior that we learn to gain control of," says Irwin
Goldstein, MD, director of San Diego Sexual Medicine and the editor in
chief of The Journal of Sexual Medicine. "Some people cannot learn to gain control (of PE), and the research into the causes is not definitive."
How long should sex last? But what's a "normal" amount of time to wait for ejaculation? The Journal of Sexual Medicine
published a study in 2005 that had 1,587 women time sex with a man from
initial penetration to climax and found that the men diagnosed with
premature ejaculation climaxed in an average of 1.8 minutes, while the
others performed for an average of 7.3 minutes—a difference of just
five and a half minutes.
Causes of PE Some link PE to
hyperthyroidism, a condition in which the thyroid gland produces too
much of the thyroid hormone thyroxine, which regulates the body's
metabolism. A small study in the December 2005 issue of the Journal of Clinical Endocrinology & Metabolism found that 50% of men with hyperthyroidism complained of PE.
Sharlip, MD, spokesman for the American Urological Association and
clinical professor of urology at University of California at San
Francisco, is not so sure. He blames PE on "subtle abnormalities in
serotonin metabolism" and, in some cases, psychological factors.
Serotonin is a neurotransmitter that regulates many functions,
including mood, appetite, and sensory perception.

Given the individuality and uniqueness of every person, some things in life have to be unified. White collars are to dress in the classic style to work, while pupils wear school uniform on a daily basis. This allows for consistency and accuracy in their respective institutions just like the formatting does in writing. For clear and digestible expression of ideas, essays follow a certain structure, consist of particular elements, and have a special layout. Read more
