Erectile Dysfunction and ED

Erectile dysfunction is sexual dysfunction characterized by the inability to develop or maintain an erection of the penis during sexual performance. A penile erection is the hydraulic effect of blood entering and being retained in sponge-like bodies within the penis. The process is often initiated as a result of sexual arousal, when signals are transmitted from the brain to nerves in the penis. Erectile dysfunction is indicated when an erection is difficult to produce. There are various circulatory causes, including alteration of the voltage-gated potassium channel, as in arsenic poisoning from drinking water. The most important organic causes are cardiovascular disease and diabetes, neurological problems (for example, trauma from prostatectomy surgery), hormonal insufficiencies (hypogonadism) and drug side effects.

Psychological impotence is where erection or penetration fails due to thoughts or feelings (psychological reasons) rather than physical impossibility; this is somewhat less frequent but often can be helped. Notably in psychological impotence, there is a strong response to placebo treatment. Erectile dysfunction, tied closely as it is about ideas of physical well being, can have severe psychological consequences. Besides treating the underlying causes such as potassium deficiency or arsenic contamination of drinking water, the first line treatment of erectile dysfunction consists of a trial of PDE5 inhibitor drugs (the first of which was sildenafil or Viagra). In some cases, treatment can involve prostaglandin tablets in the urethra, injections into the penis, a penile prosthesis, a penis pump or vascular reconstructive surgery. The Latin term impotentia coeundi describes simple inability to insert the penis into the vagina. It is now mostly replaced by more precise terms. The study of erectile dysfunction within medicine is covered by andrology, a sub-field within urology.

Erectile Dysfunction Pathophysiology

Penile erection is managed by two different mechanisms. The first one is the reflex erection, which is achieved by directly touching the penile shaft. The second is the psychogenic erection, which is achieved by erotic or emotional stimuli. The former uses the peripheral nerves and the lower parts of the spinal cord, whereas the latter uses the limbic system of the brain. In both conditions, an intact neural system is required for a successful and complete erection. Stimulation of penile shaft by the nervous system leads to the secretion of nitric oxide (NO), which causes the relaxation of smooth muscles of corpora cavernosa (the main erectile tissue of penis), and subsequently penile erection. Additionally, adequate levels of testosterone (produced by the testes) and an intact pituitary gland are required for the development of a healthy erectile system. As can be understood from the mechanisms of a normal erection, impotence may develop due to hormonal deficiency, disorders of the neural system, lack of adequate penile blood supply or psychological problems. Restriction of blood flow can arise from impaired endothelial function due to the usual causes associated with coronary artery disease, but can also be caused by prolonged exposure to bright light.

Florentine Flogging

Florentine flogging is a two-handed style of flagellation used in BDSM which involves the rhythmic use of a pair of matching floggers, one in each hand of the person administering the flogging. This technique is used to intensify the sensation of the strikes by repeating them in a more rapid manner. This should only be done after the person receiving the flogging has been warmed-up meaning to slowly, gradually bringing the blood up to the surface of the skin as to not cause injury. The skin will become pink and very warm to the touch when this has happened, letting the person administering the flogging know when it is safe to do this specialized technique. The strikes of the floggers come on the downward stroke or the top of each figure-eight flail and are thrown to avoid striking the kidney or spinal area of the subjects back as well as avoiding any areas near joints or bone. This type of flagellation should only be done on the muscular regions of the body as to prevent serious injury. This is best done with a set of identical or similar matching floggers so the weight is evenly distributed to maintain a focused, precise stroke, keeping the falls tails of the flogger together.

Acting agency

There are many acting agencies for actors to choose from and the task can be overwhelming for most. For some help with the search, go to acting agency for important information that will help you make the right choices. The main goal of any talent agency is to consistently find work for its clients. Generally, agencies will represent actors for specific areas within the entertainment industry: film, television or commercials. Many acting agencies will also represent writers and directors. It is a big advantage for any agency to have clients who are capable of acting, writing and directing. An acting agency is a business or company that represents actors (often referred to as "talent") with a common goal of generating profits by securing acting jobs.

For anyone pursuing acting or modeling, it is always good to understand the options and standards for each. Go to acting/modeling to find out the proper steps you should take. Actors generally perform on TV, appear in motion pictures and in theatre. It is standard practice for actors to audition in order to secure a job. Models also appear on TV and film; not so much in the theatre. Models also perform, but mainly at photo shoots or in runway shows.

Drooping Breast

Ptosis of the breast refers to drooping or sagging of the breast. Breast ptosis is related to the laxity of the superficial fascia, suspensory ligaments and skin.

Ptosis is a natural part of the aging process, though the rate at which a woman develops ptosis depends on many factors. Ptosis can result after pregnancy, or after weight gain and subsequent loss. Breast size is a factor in ptosis, with larger breasts becoming ptotic more quickly. Pseudoptosis is the condition where the nipple is at the level of the inframammary crease, but the breast itself has not dropped. Surgeons offering plastic surgery to address ptosis categorize the condition by the relationship that the nipple has to the inframammary crease.

Anatomically, the breasts are composed of soft, glandular tissue, with few support structures, such as connective tissue. Breasts are composed of the mammary glands, which remain relatively constant throughout life, as well as the adipose tissue or fat tissue that surrounds the mammary glands. It is the amount and distribution of adipose tissue and, to a lesser extent, glandular tissue that leads to variations in breast size. In addition, the breasts contain ligaments, although their exact function as related to breast support has not been agreed upon by experts. These ligaments and the overlying skin referred to as the dermal brassiere help determine the resulting breast shape.
